Solve the equation: 4(x-2)=12
Answer:
x = 5
Step-by-step explanation:
Given
4(x - 2) = 12 ( divide both sides by 4 )
x - 2 = 3 ( add 2 to both sides )
x = 5

Find the value of x.
Answer:
x= 128*
Step-by-step explanation:
180*-52*=128*
Answer:
x = 128
Step-by-step explanation:
well we know that for a polygon, the interior angles always add up to 360.
One angle is 52, and since the other two have squares it means that they are a perfect 90 degree angle. add those up to get 232, and then subtract 232 from 180 to get 128
I need help with this problem :)
Answer:
Replace all occurrences of y with 6x−3 in each equation.
Replace all occurrences of y in 18x−3y=9 with 6x−3 .
18x−3(6x−3)=9
y=6x−3
Simplify 18x−3(6x−3).
9=9
y=6x−3
Remove any equations from the system that are always true.
y=6x−3

Which function is represented by the graph?
f(x) = −2|x| + 1
f(x) =-1/2 |x| + 1
f(x) = -2|x + 1|
f(x) = -1/2 |x + 1|
i posted the problem just in case you need it.
Answer:
It would be the first option.
f(x) = -2 |x| + 1
If your roll a six sided die what is the probability of getting a 2 or a 6
(A) 1/3
(B) 1/4
(C) 1/6
(D) 2/3
Answer:
(A)1/3
Step-by-step explanation:
probability of getting a 2 = 1/6
probability of getting a 6 = 1/6
so the probability of getting a 2 or a 6
=(probability of getting a 2+probability of getting a 6)
=(1/6+1/6)
=2*(1/6)
=1/3
Find the value of x. 120
Answer:
x = 25
Step-by-step explanation:
2x + 70 = 120 {Subtract 70 from both sides}
2x = 120 -70
2x = 50 {divide both sides by 2}
x = 50/2
x = 25
Math help please answer question a and b ( show work please)
Answer:
a) 24 degrees
b) 50 degrees
Step-by-step explanation:
part a : use sine-1
sine-1 = [tex]\frac{opposite}{hypotenuse}[/tex]
sine-1 = [tex]\frac{17}{42}[/tex]
sine-1 = 0.405
missing angle = 23.89
round to the nearest degree = 23.89 = 24
part b : use cosine-1
cos-1 = [tex]\frac{adjacent}{hypotenuse}[/tex]
cos-1 = [tex]\frac{16}{25}[/tex]
cos-1 = 0.64
missing angle = 50.208
round to the nearest degree = 50.208 = 50

Answer:
14.9 dollars
Step-by-step explanation:
1. There are 30 students and if everyone pay the same, it will be 14.9 dollar. Because the total is 447 dolar and if everyone pay equally, then everyone have the same amount. So, 447 dollar divided to 30 student equal 14.9 per student.
2. The essential information is the total cost of money and the amount of student.
3. 30m = 447
/30 /30
m= 14.9 dollar
4. 14.9*30 = 447

Answer:
AB, BC, AC
Step-by-step explanation:
Hi there,
In order to solve this problem, we should know that the longest side of the triangle is always opposite of the largest angle in a triangle. The first step is to find the angle measures. We are given the measures of ∠A and ∠C.
To find m∠B, just subtract the sum of the other angles and subtract the value from 180.
m∠A + m∠C + m∠B = 180°
65° + 40° + m∠B = 180°
105° + m∠B = 180°
m∠B = 75°
Now that we know all of the angle measures, we can identify the the lengths of the sides from least to greatest by looking at the angle value. The greater the angle measure, the longer the opposite side would be.
m∠A = 65° ⇒ opposite of side BC = medium side
m∠B = 75° ⇒ opposite of side AC = longest side
m∠C = 40° ⇒ opposite of side AB = shortest side
Hope this explanation helps. Cheers.

State the domain, the range, and the intervals on which function is increasing, decreasing, or constant in interval notation
Answer:
Domain: [tex][-1,\infty)[/tex]
Range: [tex](-\infty, 3][/tex]
Decreases over: [tex](-1,-\infty)[/tex]
Step-by-step explanation:
Given
[tex]f(x) = -\sqrt{x + 1} + 3[/tex] --- Missing from the question
Solving (a): The domain
To get the domain, the expression under the square root must not be negative.
In other words:
[tex]x + 1 \ge 0[/tex]
Solve for x
[tex]x + 1 -1\ge 0-1[/tex]
[tex]x \ge -1[/tex]
Hence, the domain is:
[tex][-1,\infty)[/tex]
To get the range, we plot the values of the domain in the expression.
[tex]x = -1[/tex]
[tex]f(x) = -\sqrt{x + 1} + 3[/tex]
[tex]f(-1) = -\sqrt{-1+1} +3[/tex]
[tex]f(-1) = -\sqrt{0} +3[/tex]
[tex]f(-1) = -0 +3[/tex]
[tex]f(-1) = 3[/tex]
[tex]x = \infty[/tex]
[tex]f(\infty) = -\sqrt{\infty +1}+3[/tex]
[tex]f(\infty) = -\sqrt{\infty}+3[/tex]
[tex]f(\infty) = -\infty+3[/tex]
[tex]f(\infty) = -\infty[/tex]
So, the range is: [tex](-\infty, 3][/tex]
To get the interval where the function increases or not, we simply plot the graph of f(x).
See attachment for graph.
From the attachment, it will be observed that the graph of f(x) continuously decreases from x = -1, and it never increased.
This implies that, the graph decreases over the interval [tex](-1,-\infty)[/tex]

RESEARCH STUDY 11.2: Dr. Bloedorn is a health psychologist who researches nutrition. She is curious as to whether a new drink additive will help people consume fewer calories during a meal. The drink additive is a white, odorless, tasteless powder that a person can add to any drink. She collects a random sample of 63 overweight students on campus and measures the calories they eat during lunch using a bomb calorimeter. She then gives this additive to the same 63 participants to use at dinner and measures how many calories they eat (again using the bomb calorimeter). Imagine that Dr. Bloedorn finds no difference between the calories consumed with the drink additive and without. This is known as

This is known as null effect
Step-by-step explanation:
A null effect is the outcome of an experiment that does not give the effect or result expected. Although an experiment with a null effect has a result, however the result of the experiment does not support the hypothesis
An example of a null result that remains importantly useful is the Michelson-Morley experiment from that partly made possible the formulation of special relativity theory

find the missing dimension of the cone
Answer:
h=1ft
Step-by-step explanation:
The volume of a cone is:
v=πr^h/3
plug in the values (I am assuming not 1/18π but 1/18×π):
1/18π= π1/3^2h/3
Get rid of the radius:
1/3^2=1/9
Continue:
π/18= πh/3*1/9= πh/18
Remove the denominators:
π=πh
Divide both sides by π :
h=1

Two fair coins are being used in a probability experiment. During each trial of the experiment, the
coins are flipped and the outcomes are recorded with H representing heads and T representing tails.
There are four possible outcomes: HH. HT. TH, and TT. What is the probability, on each trial of the
experiment, that the outcome is one head and one tail, in any order?
25%
33%
50%
75%
Answer: 50%
Step-by-step explanation:
If we can get a head tails combo in any order we could get a head/tails or a tails/head so there is a 50% probability of getting that combo in a trial

To find the diameter of a circle, you multiply the radius (the radius is the distance from the outside of the circle to the middle) by 2.
Ex: the first one has 6m as the radius. So you would multiply the 6 by 2. Which would be 12.
The radius is half of the diameter. So for number 8, the answer would be 2.

Step-by-step explanation:
James ran 4 laps and walked 2 laps When running his average speed was 2.5 minutes per lap When walking his average speed was 4.9 minutes per lap How long did it take James to complete 6 laps? 7.4 minutes 9.9 minutes 14.8 minutes Or 19.8 minutes
Answer:
19.8 minutes
Step-by-step explanation:
Total time the 4 laps was completed = 4 x 2.5 = 10 minutes
Total time the 2 laps was completed = 2 x 4.9 = 9.8 minutes
total time = 10 minutes + 9.8 minutes = 19.8 minutes
