Answer:
22 blue blocks
17 green blocks
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations:
There are five more blue blocks than green blocks.
So, the number of blue blocks (b) is equal to the number of green blocks (g) plus 5.
b = g+5Three times the number of green blocks (3g), increased by double the (+2b) number of blue, equals 95.
3g+2b =95The system is
b = g+5
3g+2b =95
Replacing b=g+5 in the second equation:
3g + 2 (g+5)=95
Solving for g:
3g +2g+10 =95
5g = 95-10
5g=85
g= 85/5
g= 17
Replacing g=17 in the first equation:
b = g+5
b = 17 +5
b=22
A painter is painting a rectangular wall that measures 22.8 ft by 17.3 ft. Each gallon can of paint covers 100 square feet. What are the fewest gallons needed to paint the wall?
____gallons
Answer:
1.548 gallons
Step-by-step explanation:
Length of the rectangular wall = 25.1 ft.
Width of the rectangular wall = 18.5 ft.
Area of the rectangular wall = length * width = 25.1 * 18.5
= 464.35 square feet
300 square feet wall can be painted using 1 gallon of paint.
=> 1 square feet wall can be painted using gallon of paint.
=> 464.35 square feet wall can be painted using gallon of paint.
= 1.548 gallons of paint
Answer:
4 gallons
Step-by-step explanation:
The first thing you want to do is times 22.8 * 17.3 = 394.44. Then what you want to do is see how much 100 square gallons can cover the area : 4. If we make it 3 it is going under if it is 4 it can cover the whole thing, and if we make it 5 we have a little much.

Answer:
x≤-3 2 ≤x<7
Step-by-step explanation:
(x^2+x-6) /(x-7) ≤0
Factor the numerator
(x+3)(x-2) / (x-7)≤0
Critical points are
X =-3 X =2 X=7
We need to check the values when
x≤3 -3 ≤ x≤2 2 ≤x<7 x>7
(x cannot be 7 because then the denominator is zero)
and see when it is less than 0
Substitute a value in and see if factor is positive or negative
x≤-3
(negative)(negative) / (negative) = negative
-3 ≤x≤2
(positive)(negative) / (negative) = positive this range does not work
2 ≤x<7
(positive)(positive) / (negative) = negative
x>7
(positive)(positive) / (positive)

Suppose you deposit $2,000 in a savings account that pays interest at an annual rate of 5%. If no rioney is added or withdrawn from the account, answer the following questions.
a. How much will be in the account after 4 years?
b. How much will be in the account after 17 years?
c. How many years will it take for the account to contain $2,500?
d. How many years will it take for the account to contain $3,000?
a. After 4 years, the amount in the account will be $
(Do not round until the final answer. Then round to the nearest cent as needed.)
Answer:
a. $ 2,431.01 = 4 years
b. $ 4,584.04 = 17 years
c. 4.57 years = $ 2,499.57
d. 8.3 year = $ 2,998.48
e. $ 2,431.01 = 4 years
Step-by-step explanation:
Compound Interest Equation
A = P(1 + r/n)nt
Where:
A = Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
R = Annual Nominal Interest Rate in percent
r = Annual Nominal Interest Rate as a decimal
r = R/100
t = Time Involved in years, 0.5 years is calculated as 6 months, etc.
n = number of compounding periods per unit t; at the END of each period
n is an integer and -2
Write down the possible values of n,
from smallest to largest.
Answer:
Step-by-step explanation:
-2 < n+3 ≤ 4
Make two separate equations,
-2 < n+3
Subtract 3 from both sides,
-2-3 < n + 3 -3
-5 < n
So, value of n should be greater than (-5)
n +3 ≤ 4
Subtract 3 from both sides
n ≤ 1
So, n value should be less than or equal to 1
So, n value should be greater than -5 and less than or equal to 1
n= { -4, -3 , -2 , -1 ,0 ,1 }

If AB = CA and m1 = 45°, what is m3?
A.
47°
B.
45°
C.
43°
D.
90°
Answer:
B 45 degrees
Step-by-step explanation:
if AB and CA are = the M2 = 90 degrees
in an right triangle ware one angle is 90 degrees and one is 45 degrees the outer one will be 45 degrees
the total of the angles in a triangle is 180 degrees so 180 - 90 = 90
90 - 45 = 45
so the remaining angle is 45.
A student is asked to find the length of the hypotenuse of a right triangle. The length of one leg is 26
centimeters, and the length of the other leg is 24 centimeters. The student incorrectly says that the
length of the hypotenuse is 7.1 centimeters. Answer parts a and b.
a. Find the length of the hypotenuse of the right triangle to the nearest tenth of a centimeter.
Answer:
c ≅ 35.4 cm.
Step-by-step explanation:
To find the length of the Hypotenuse of a triangle, the formula a² + b² = c² will need to be used. Therefore:
26² + 24² = c² (c is the hypotenuse)
1252 = c²
√1252 = c
c ≈35.38
Round to tenths place:
c ≅ 35.4 cm. This is the Hypotenuse of the triangle.

D. g(x) = (x + 51
Answer: i thini its 2
Step-by-step explanation:
The function g(x) is:
g(x) = Ix - 5I.
Therefore, the option A in the given question is correct.
What is transformation on the graphs?When a function is transformed, the graph's curve either "moves to the left, right, up, or down," "expands or compresses," "reflects," or all three.
The function is made possible by the fundamental function f(x) and the constant
g(x) = f(x - k),
horizontally moving, the f(x) k unit coordinates may be drawn.
The shift's direction depends on the value of k. Specifically,
If k > 0, the basis graph shifts right by k units.
If k < 0, the base graph shifts k units to the left.
Given that the parent function is f(x) = IxI.
From the definition,
the transformed function is moved horizontally to 5 units to the right.
So, the function is g(x) = Ix - 5I.
Therefore, g(x) = Ix - 5I.

Your question is incomplete; most probably, your complete question is this:
Which represents continuous data? A) The number of times you flip a coin B) The number of students in a classroom C) The number of chocolate candies in a box D) The price of fish per pound
Answer:
D) The price of fish per pound
Step-by-step explanation:
A continuous data is one which can take any value . it can have even value between any two consecutive number.
Example :
continuous data can have value between 4 and 5 like 4.5 4.001 and so on.
Discrete data is one which can be counted such as number of flowers, no of cars in parking.
it can take value such as 1,2, 12, 66 etc.
____________________________________________
Let go through the option
A) The number of times you flip a coin
We can count the number of times a coin is flipped .
Like 2 times, 3 times and hence it is discrete data and not a continuous one.
B) The number of students in a classroom
Student in a classroom can also be counted.
in a class there can be 12, 50, 66 etc students not 12.1 , 50.5 etc.
hence it is discrete data and not a continuous one.
C) The number of chocolate candies in a box
Again, chocolate number can be counted .
Number of chocolate can be 2, 4, 5 and not 2.1 , 4.6 etc and
hence it is discrete data and not a continuous one.
D>The price of fish per pound
Price of fist cannot be counted . Further, price of fish can be $2.5 , $ 4.555
hence it is a continuous data.
Based on above discussion
continuous data is represented by The price of fish per pound
4) Members of the school band are buying bouquets of flowers to sell at the fundraiser.
They plan on buying 120 bouquets of flowers. The ratio of the number of bouquets of roses to the number of bouquets of sunflowers will be 5/3. How many bouquets of flowers did they buy?
Bouquet of Roses?
Bouquet of Sunflowers?
Answer: Roses= 75, Sunflowers= 45
Step-by-step explanation:
Add the ratios- 5 + 3 = 8
Divide the total by the sum = 120 ÷ 8 = 15
Multiply the ratios- 5 x 15 = 75 and 5 x 3 = 45
∴ 5:3 = 75 , 45
Phone company A conducted a study that showed 97% customer satisfaction, with a standard deviation of 1%. The sample included 25 people who appear in one of their commercials during the past three years
phone company B conducted a study to show 94% customer satisfaction with a standard deviation of 4% a random sample consisting of 100 customers
which of the company claims is more believable and why? 
A.Phone Company A because the time span was longer
B. Phone company B bc the sample was not biased
C. Company A bc the standard deviation is smaller
D.Company B because the standard deviation is larger
Answer:
B. Phone company B because the sample was not biased.
Step-by-step explanation:
While Phone company A had a higher satisfaction rate, 25 people that conducted this poll were in at least 1 commerical of the phone company's in the past 3 years. This means that their reflection of the company is biased (typically higher) and not completely based off of their performance but instead how cool it was to be in a commerical or how much they were paid. If the poll was a more random sample of just customers, it would be more believable data. On the other hand, while phone company B had a lower satisfaction rate and higher deviation, their statistics are more believable due to the random sampling of customers.

B

A study was done by an online retail store to determine the rate at which users used its website. A graph of the data that was collected is shown: A line graph with Number of Months on the x axis and Number of Users, in thousands, on the y axis. The x axis has a scale from 0 to 36 with an increment of 4. The y axis has a scale of 0 to 60 with increments of 6. A straight line connecting 0, 0 and approximately 36, 54 is drawn. What can be interpreted from the range of this graph? The range represents the 54-month time period of the study. The range represents the 36-month time period of the study. The range represents the number of users each month for 36 months. The range represents the number of users each month for 54 months.PLEASE HELP IT URGENT
Answer:
The correct option is C.
C) The range represents the number of users each month for 36 months
Step-by-step explanation:
We have been given that:
x-axis ⇒ Number of Months
y-axis ⇒ Number of Users
x-axis values = 0 to 36
y-axis values = 0 to 60
We have a function which is represented by a straight line from (0,0) to (36,54).
We have to find the RANGE of the function.
Range of a function is a complete set of values of dependent variable y, for all possible values of independent variable x
As total number of months = 36
Range is the set of all values of y (Number of Users) for each month for a period of 36 months.
Hence, the correct option is C.
