GIVING BRAINLIST WHOEVER GETS IT RIGHT!!!!!!!!!!!!!!!!!!!! Select the correct answer.
Sam's height is 15 centimeters less than 2 times Martha's height. If Sam is 185 centimeters tall, and Martha's height is x, the relationship between the heights can be represented by the equation 2x − 15 = 185. What is Martha's height?
Step-by-step explanation:
The equation 2x − 15 = 185 represents the relationship between Sam's and Martha's heights. We can solve for x, which represents Martha's height, by isolating x on one side of the equation:
2x − 15 = 185
Add 15 to both sides of the equation:
2x = 200
Divide both sides of the equation by 2:
x = 100
Therefore, Martha's height is 100 centimeters.
Simplify the expression below.
5^2 + 9^2
To simplify the expression 5^2 + 9^2, we can evaluate the squares of 5 and 9 and then add the results:
5^2 = 5 x 5 = 25
9^2 = 9 x 9 = 81
So, 5^2 + 9^2 = 25 + 81 = 106
Therefore, the simplified form of the expression 5^2 + 9^2 is 106.

14 points! PLEASE HELP!!!
Step-by-step explanation:
I just did in the other posting. how often did you post it ?
this is a trick question. the triangle at the top is not an isoceles triangle.
we use Pythagoras for an the steps.
so, the left part of the baseline (split by the height) is calculated by
12² = 10² + part²
144 = 100 + part²
part = sqrt(44) = 6.633249581... ft
the other part is then
20 - 6.633249581... = 13.36675042... ft
and the second leg of the large triangle is
leg² = 10² + 13.36675042...² = 278.6700168...
leg = 16.69341238... ft
P = 12 + 16.69341238... + 8 + 8 + 20 = 64.69341238... ft ≈

PLEASE HELP! Find missing side lengths of B and C. Explain
Answer:
b=7 & c=7√2
Step-by-step explanation:
b=7 as it is an isosceles triangle
now using Pythagoras theorem,
(c)^2= (7)^2+(7)^2
⇒(c)^2= 49+49
⇒(c)^2= 98
⇒c= √98
⇒c=7√2
Answer:
b = 7c = 7√2Step-by-step explanation:
You want the missing side lengths in an isosceles right triangle with one side given as 7.
Isosceles right triangleThe two congruent acute angles tell you this right triangle is isosceles. That means sides 7 and b are the same length:
b = 7
The hypotenuse of an isosceles right triangle is √2 times the side length:
c = 7√2
__
Additional comment
You can figure the hypotenuse using the Pythagorean theorem if you haven't memorized the side relations of this "special" right triangle.
c² = 7² + b²
c² = 7² +7² = 2·7²
c = √(2·7²) = 7√2
The side length ratios for an isosceles right triangle (angles 45°-45°-90°) are 1 : 1 : √2.
The other "special" right triangle is the 30°-60°-90° triangle, which has side length ratios 1 : √3 : 2.
On a field trip, the ratio of adults to students is 1:8. Which of the following statements about the field trip must be true? (A) A total of 9 people went on the field trip. B. The total number of people on the trip is a multiple of 8. C. There were 7 more students than adults on the field trip. D. There were 8 times as many students as adults on the field trip.
Answer:
B
Step-by-step explanation:
The correct answer is B. The total number of people on the field trip must be a multiple of 9 (1 adult and 8 students).
A is not true because if there were only 9 people, there could not be both an adult and 8 students, and the ratio would not be 1:8.
C is not necessarily true. It is possible that there were more adults than students on the field trip, or that the ratio was not an exact 1:8.
D is not true because if there were 8 times as many students as adults, the ratio would be 1:64, not 1:8

Lola hosts a podcast about computers, and Franco hosts a podcast about parenting. Both podcasts have a set duration for each episode. Last year, Lola released 17 episodes and Franco released 43 episodes, for a total of 5,645 minutes of content. This year, Lola released 36 episodes and Franco released 43 episodes, which lasted a total of 6,956 minutes. How long is each episode?
Answer:
Let's denote the duration of each episode of Lola's podcast by "L" and the duration of each episode of Franco's podcast by "F".
From the information given, we can write two equations based on the total duration of content for the two years:
17L + 43F = 5,645 (equation 1)
36L + 43F = 6,956 (equation 2)
To solve for L and F, we can eliminate F by subtracting equation 1 from equation 2:
(36L + 43F) - (17L + 43F) = 6,956 - 5,645
Simplifying, we get:
19L = 1,311
Therefore, the duration of each episode of Lola's podcast (L) is:
L = 1,311 / 19
L ≈ 69.0 minutes
To find the duration of each episode of Franco's podcast (F), we can substitute the value of L into either equation 1 or 2:
17L + 43F = 5,645
17(69.0) + 43F = 5,645
1,173 + 43F = 5,645
43F = 4,472
F = 4,472 / 43
F ≈ 104.0 minutes
Therefore, each episode of Lola's podcast is approximately 69.0 minutes long, and each episode of Franco's podcast is approximately 104.0 minutes long.
the angle has 4x and 6x what is the measurement of the angle
The sum of the measures of the two angles is 180 degrees, as they are angles of a straight line. The measure of the first angle is 4x = 72 degrees, and the measure of the second angle is 6x = 108 degrees.
What is angle ?
A measure of rotation of two crossing lines or planes in mathematics is called an angle. Angles are frequently defined as degrees or radians. Two lines or splines intersect at a location, known as the apex of the angle, to produce an angle. The edges of the angle are the two lines and line segments. According to its measurement, an angle can be categorized as: An acute angle is one that ranges from 0 to 90 degrees. Right arc: an angle that is 90 degrees in length. A measureable angle intermediate 90 and 180 degrees is referred to as an obtuse angle. 180 degree angle is referred to as a straight angle.
The sum of the measures of the two angles is 180 degrees, because they are angles of a straight line. Therefore:
4x + 6x = 180
Simplifying the left-hand side, we get:
10x = 180
Dividing both sides by 10, we obtain:
x = 18
So the measure of the first angle is:
4x = 4(18) = 72 degrees
And the measure of the second angle is:
6x = 6(18) = 108 degrees

The quadrilateral on the graph below is rotated about the point (0, 0). What are the new coordinates of Point B and Point C after a 90 degree clockwise rotation?
A 90 degree clockwise rotation about the point (0,0), the new coordinates of Point B are (3, -1) and the new coordinates of Point C are (1, -2).
How do you check if a quadrilateral is a rectangle on a graph?A quadrilateral can be proven to be a rectangle in a number different ways. Here are the three simplest methods: 1. Establish that all angles are 90 degrees; 2. Establish that two opposed angles are 90 degrees; and 3. Establish that the diagonals are equally long and intersect one another.
The following transformation matrix can be used to rotate a point (x,y) 90 degrees clockwise with respect to the origin (0,0):
|0 1|\s|-1 0|
This transformation matrix can be applied to each point to determine its new coordinates upon rotation.
Point B is the first point, and its initial coordinates are (-1, 3). The transformation matrix in use:
|0 1| |-1| |3|
|-1 0| x |3| = |-1|
After rotating Point B 90 degrees clockwise, the new coordinates are: (3, -1).
The transformation matrix is then applied to Point C, whose initial coordinates are (2, 1):
|0 1| |2| |1|
|-1 0| x |1| = |-2|
After rotating in a clockwise direction by 90 degrees, Point C's new coordinates are (1, -2).
As a result, after rotating 90 degrees in a clockwise direction around Point 0, Point B's new coordinates are (3, -1), while Point C's new coordinates are (1, -2).

Based on the graph of the polynomial f(x), the following is not a factor: B. (x - 1).
What is a polynomial graph?In Mathematics and Geometry, a polynomial graph simply refers to a type of graph that touches the x-axis at zeros, roots, solutions, x-intercepts, and factors with even multiplicities.
Generally speaking, the zero of a polynomial function simply refers to a point where it crosses or cuts the x-axis of a graph. Since the polynomial function with x-intercepts at x = -4, x = 0, and x = 5 cuts the x-axis at three (3) points. Therefore, the degree of this polynomial is either greater than or equal to three (3).
By critically observing the graph of the polynomial function shown above, we can logically deduce that its x-intercepts include the following;
x = -1 ⇒ x + 1 = 0.
x = -2 ⇒ x + 2 = 0.
x = 2 ⇒ x - 2 = 0.
x = 3 ⇒ x - 3 = 0.

Yes, quadrilaterals LMNO and PQRS are similar because a rotation and a dilation map quadrilateral LMNO onto PQRS.
Yes, quadrilaterals LMNO and PQRS are similar because a reflection and a dilation map quadrilateral LMNO onto PQRS.
No, quadrilaterals LMNO and PQRS are not similar because their corresponding segments are not proportional.
The correct answer is (d) No, quadrilaterals LMNO and PQRS are not similar because their corresponding sides are not proportional.
What are quadrilaterals?A quadrilateral is a geometric shape with four sides and four corners.
To be classified as a quadrilateral, its shape must be a closed figure with four straight sides and four interior angles.
To determine quadrilaterals are similar, we need to check if corresponding angles are congruent and corresponding sides are proportional.
Checking corresponding angles are congruent:
∠ L to ∠P.
∠M to ∠Q.
∠ N to ∠ R.
∠O to ∠S.
All corresponding angles are congruent. Therefore, quadrilaterals have the same shape.
Check if corresponding sides are proportional.
LM =√((-1 - (-2))² + (4 - 2)²) = √(2² + 2²) = 2√2
MN = √((3 - (-1))² + (4 - 4)²) = √(4²) = 4
NO = √((4 - 3)² + (2 - 4)²) = √(2² + 2²) = 2√(2)
OL = √((-2 - 4)² + (2 - (-6))²) = √(6² + 8²) = 10
PQ = √((4 - 2)² + (-2 - (-6))²) = √(2² + 4²) = 2√5
QR = √((12 - 4)² + (-2 - (-2))²) = √(8²) = 8
RS = √((15 - 12)² + (-6 - (-2))²) = √(3² + 4²) = 5
SP = √((2 - 15)² + (-6 - (-6))²) = √(13²) = 13
LM / PQ = (2√2) / (2√5) = √(8/5)
MN / QR = 4 / 8 = 1/2
NO / RS = (2√(2)) / 5√(1) = (2/5)√(2)
OL / SP = 10 / 13
The corresponding sides are not proportional because they are not all equal or proportional to each other. Therefore, we can conclude that the quadrilaterals LMNO and PQRS are not similar.

b) the probability of catching a medium-sized guppy from the tank is 0.1391.
c) the probability of catching a guppy if we randomly select a medium-sized fish from the tank is 0.4375.
d) the probability of catching a medium-sized guppy if we randomly select a guppy from the tank is 0.3206.
e) the probability of catching a fish that is not a goldfish if we randomly select a fish from the tank is 0.6291.
f) 0.1384 is not equal to 0.1391, which indicates that the two events are not independent
Probability is a measure of the likelihood or chance of an event occurring, expressed as a number between 0 and 1, with 0 indicating impossibility and 1 indicating certainty.
The explanation to the above probability answer are given below:
a)
From the contingency table, we can see that the total number of medium-sized fish is 96. The total number of fish in the tank is 302. Therefore, the probability of catching a medium-sized fish is:
Probability of catching a medium-sized fish = Total number of medium-sized fish / Total number of fish
Probability of catching a medium-sized fish = 96 / 302
Probability of catching a medium-sized fish = 0.3182
Therefore, the probability of catching a medium-sized fish from the tank is 0.3182
b)
From the contingency table, we can see that the total number of medium-sized guppies is 42. The total number of fish in the tank is 302. Therefore, the probability of catching a medium-sized guppy is:
Probability of catching a medium-sized guppy = Total number of medium-sized guppies / Total number of fish
Probability of catching a medium-sized guppy = 42 / 302
Probability of catching a medium-sized guppy = 0.1391
Therefore, the probability of catching a medium-sized guppy from the tank is 0.1391.
c)
From the contingency table, we can see that the number of medium-sized guppies is 42, and the number of medium-sized fish is 96. Therefore, the probability of catching a guppy if we randomly select a medium-sized fish is:
Probability of catching a guppy given a medium-sized fish = Number of medium-sized guppies / Total number of medium-sized fish
Probability of catching a guppy given a medium-sized fish = 42 / 96
Probability of catching a guppy given a medium-sized fish = 0.4375
Therefore, the probability of catching a guppy if we randomly select a medium-sized fish from the tank is 0.4375.
d)
To calculate the probability of catching a medium-sized guppy if we randomly select a guppy from the tank, we need to find the number of medium-sized guppies in the tank and divide it by the total number of guppies in the tank.
From the contingency table, we can see that the number of medium-sized guppies is 42, and the total number of guppies is 131. Therefore, the probability of catching a medium-sized guppy if we randomly select a guppy from the tank is:
Probability of catching a medium-sized guppy given a guppy = Number of medium-sized guppies / Total number of guppies
Probability of catching a medium-sized guppy given a guppy = 42 / 131
Probability of catching a medium-sized guppy given a guppy = 0.3206
Therefore, the probability of catching a medium-sized guppy if we randomly select a guppy from the tank is 0.3206.
e)
From the contingency table, we can see that the total number of non-goldfish is 190 (45 medium goldfish + 70 small guppy + 42 medium guppy + 9 medium gourami + 10 large gourami + 14 small gourami). The total number of fish in the tank is 302. Therefore, the probability of catching a fish that is not a goldfish is:
Probability of catching a fish that is not a goldfish = Total number of non-goldfish / Total number of fish
Probability of catching a fish that is not a goldfish = 190 / 302
Probability of catching a fish that is not a goldfish = 0.6291
Therefore, the probability of catching a fish that is not a goldfish if we randomly select a fish from the tank is 0.6291.
f)
From the contingency table, we can see that the probability of randomly catching a guppy is 131/302, which is approximately 0.4344. Similarly, the probability of randomly catching a medium-sized fish is 96/302, which is approximately 0.3182.
Now, let's consider the joint probability of randomly catching a medium-sized guppy, which we calculated earlier to be 42/302, or approximately 0.1391. To determine if the events are independent, we need to compare the product of the probabilities of the individual events (catching a guppy and catching a medium-sized fish) to the joint probability of the events occurring together.
If the events are independent, then the product of their individual probabilities should be equal to the joint probability:
P(catching a guppy) x P(catching a medium-sized fish)
= P(catching a medium-sized guppy)
0.4344 x 0.3182 = 0.1391
0.1384 is not equal to 0.1391, which indicates that the two events are not independent.

In PQR, PQ= 5.4, QR= 3.6, and PR=6.2. To the nearest Tenth, what is M∠R
Therefore , the solution of the given problem of angles comes out to be M∠R measured at 45.4 degrees, to the closest tenth.
An angle meaning is what?The intersection of the lines that form a skew's ends determines the size of its biggest and smallest walls. There's a possibility that two paths will intersect at a junction. Angle is another outcome of two things interacting. They mirror dihedral forms the most. A two-dimensional curve can be created by placing two line beams in various configurations between their ends.
Here,
To determine the size of angle R in triangular PQR, we can apply the Law of Cosines:
=> cos(R) = (PQ₂ + PR₂ - QR₂) / (2 * PQ * PR)
=> cos(R) = (5.4₂ + 6.2₂ - 3.6₂) / (2 * 5.4 * 6.2)
=> cos(R) = 0.6960917
When we calculate the inverse cosine of both sides, we obtain:
=> R = cos⁻¹(0.6960917)
=> R equals 45.4 degrees
Angle R in triangle PQR is therefore measured at 45.4 degrees, to the closest tenth.

A line has a slope of 5/6
and passes through the point (7,6). Write its equation in slope-intercept form.
Answer:
y = 5/6x + 1/6
Step-by-step explanation:
m = 5/6, x = 7, y = 6
y = mx + b
6 = 5/6(7) + b
b = 6 - 35/6
b = 36/6 - 35/6 = 1/6
y = 5/6x + 1/6
Answer:
Below
Step-by-step explanation:
Here is another way:
Start with point ( 7,6) slope ( m= 5/6) form :
(y-6) = 5/6 ( x-7) expand
y-6 = 5/6 x - 35/6 add 6 to both sides
y = 5/6 x + 1/6 Done.
An oil-producing country can sell 7 million barrels of oil a day at a price of $80 per barrel. If each $1 price increase will result in a sales decrease of 100,000 barrels per day, what price will maximize the country's revenue?
$
How many barrels will it sell at that price?
barrels
Answer:
Step-by-step explanation:
To find the price that maximizes the country's revenue, we need to consider the relationship between price, sales, and revenue.
Let's start by calculating the current revenue for the country:
Revenue = Price × Sales
Revenue = $80/barrel × 7 million barrels/day
Revenue = $560 million/day
Now let's consider the effect of a price increase on sales. According to the problem, a $1 increase in price will result in a decrease of 100,000 barrels/day in sales. This means that the new sales rate at a price of $81/barrel will be:
New sales = 7 million barrels/day - 100,000 barrels/day per $1 increase × (81 - 80)
New sales = 6.9 million barrels/day
The new revenue at a price of $81/barrel will be:
New revenue = $81/barrel × 6.9 million barrels/day
New revenue = $559.9 million/day
We can repeat this process for a range of prices to see how revenue changes:
Price Sales (million barrels/day) Revenue (million $/day)
80 7.0 560.0
81 6.9 559.9
82 6.8 544.0
83 6.7 534.1
84 6.6 528.0
85 6.5 520.0
From this table, we can see that the price that maximizes revenue is $84/barrel. At this price, the country will sell 6.6 million barrels/day, and generate revenue of $528 million/day.
Therefore, the price that will maximize the country's revenue is $84/barrel, and it will sell 6.6 million barrels/day at that price.
A company's sales in Seattle were $410,000 in 2012, while their sales in Portland were $255,000 for the same year. Complete the following statements:
a. Seattle's sales were ___% larger than Portland's.
b. Portland sales were ___ % smaller than Seattle's.
c. Portland sales were ___ % of Seattle's.
Give answers accurate to at least one decimal place.
In 2012, a company made $410,000 in sales in Seattle but only making $255,000 in sales in Portland. Fulfill each of the following claims:
a. Seattle outsold Portland in sales by 60.78%.
b. Portland's sales lagged Seattle's by 60.78%.
c. Sales in Portland were 62.2% of those in Seattle.
a. Seattle's sales were ___% larger than Portland's.
To calculate the percentage difference between the two sales figures, we can use the following formula:
Percentage difference = ((larger value - smaller value) / smaller value) x 100%
Substituting the values, we get:
Percentage difference = ((410,000 - 255,000) / 255,000) x 100%
Percentage difference = 155,000 / 255,000 x 100%
Percentage difference = 0.6078 x 100%
Percentage difference = 60.78%
Therefore, Seattle's sales were 60.78% larger than Portland's.
b. The sales in Portland were ___% less than those in Seattle.
Since Portland's sales were smaller than Seattle's, we can simply use the percentage difference we calculated above to find the percentage by which Portland's sales were smaller:
Portland sales were 60.78% smaller than Seattle's.
c. Portland sales were ___ % of Seattle's.
To calculate the percentage of Seattle's sales that Portland's sales represent, we can use the following formula:
Percentage = (smaller value / larger value) x 100%
Percentage = 0.62195 x 100%
Substituting the values, we get:
Percentage = (255,000 / 410,000) x 100%
Percentage = 62.2%
Therefore, Portland's sales were 62.2% of Seattle's.

The inequality that determines the maximum number of speakers, x, Michael can buy is: B. $46.00 + $483.33 < $1,045.69
How to Solve Inequalities?To determine the maximum number of speakers, x, Michael can buy without spending more money than he has in his account, we need to use the following inequality:
Total amount spent on TV and speakers ≤ amount of money in the account
We know that Michael has $1,045.69 in his account, and he will spend $483.33 on a new television. Let x be the maximum number of speakers he can buy. Each speaker costs $46.00, so the total amount spent on the speakers will be $46.00x. Thus, we can write the inequality as:
$483.33 + $46.00x ≤ $1,045.69
Simplifying this inequality, we get:
$46.00x ≤ $1,045.69 - $483.33
$46.00x ≤ $562.36
x ≤ $562.36 ÷ $46.00
x ≤ 12.20 (rounded to two decimal places)
So the maximum number of speakers Michael can buy without spending more money than he has in his account is 12.20. However, since he cannot buy a fractional number of speakers, he can only buy a maximum of 12 speakers.
Therefore, the correct inequality that determines the maximum number of speakers, x, Michael can buy without spending more money than he has in his account is:
B. $46.00 + $483.33 < $1,045.69
