Which expression has a value of 35 when p = 7?
Answer:
B) 5p
Step-by-step explanation:
If you substitute 7 in for each equation you will see that the answers are either 7, 38, or 32, which are not 35. But when you substitute 7 in for B, 5(7), and multiply it out you get 35. I hope this helps :)

Caroline and Ben are playing a game using this spinner.
Caroline will win the game if her next spin lands on a section labeled E or F.
Caroline claims that it is likely, but not certain, that she will win the game on her next spin.
Explain why Caroline's claim is not correct.
Answer:
Caroline's claim is not correct because the probability of her winning is 1/3 or 2/6 which is unlikely.
Step-by-step explanation:
The spinner can land on 6 different sections, in order for Caroline to win her spin must land on E or F.

a framer sells 16 pounds or his small 48 pound potato crops what percent does he sell
Answer:
Is it 32
Step-by-step explanation:
I think your suppose to subtract if you get it wrong i'm sorry
Answer:
33.3333333% (with the 3 repeating forever)
Step-by-step explanation:
If they sell 16 pounds/48 pounds, you can first simplify this fraction:
16/48 = 1/3.
Then, you do 1 divided by 3 and you would get 0.33333...
As a percent, this is 33.3% (where the 3 is repeating forever)

Is that right? Is x equal to 6?
Answer:
x=4
Step-by-step explanation:
It can't be x=6 because 15x6 is 90 and that doesn't allow for the 8x-2. The bottom half has to equal 180 because it's a straight line. So, 18x4=60. Then 8(4)-2 equals 30. 30+60=90. 90+90 equals 180.

First, find out how much he earns in one week-so $8 times 40 = 320. Then multiply 320 by 6 to get how much earns in 6 weeks which is $1920.
(hope this helps :P)
Answer:
1920
Step-by-step explanation:
Multiply the amount of money by the amount of hours. 8x40=320. Then multiply that by the number of weeks. 320x6=1920.

An open box is to be made by using a piece of sheet metal with the dimensions of 4m by 2m. Determine the dimensions the box should be to maximize volume by cutting out the four corners of the material and folding up the edges to make the box. The material that is cut out is waste and cannot be used.
Answer:
Dimensions: 0.4 by 3.2 by 1.2
Step-by-step explanation:
I'm assuming here that we are cutting out squares out of each of the metal's corners:
Let x = the length of each cut-out square,
Each base (of the desired net square folded) is 4-2x, and 2-2x respectively,
Volume = x(4-2x)(2-2x)
= 4x^3 - 12x + 8x
Now we take the derivative:
[tex]\frac{d}{dx}\left[4x^3-12x^2+8x\right]\\\\= \frac{d}{dx}\left(4x^3\right)-\frac{d}{dx}\left(12x^2\right)+\frac{d}{dx}\left(8x\right)\\\\= 12x^2-24x+8[/tex]
We equate to 0 (0 for max volume), and solve using the quadratic formula:
[tex]12x^2-24x+8=0,\\\\x_{1,\:2}=\frac{-\left(-24\right)\pm \sqrt{\left(-24\right)^2-4\cdot \:12\cdot \:8}}{2\cdot \:12}\\\\= \frac{-\left(-24\right)\pm \:8\sqrt{3}}{2\cdot \:12}\\\\\mathrm{Separate\:the\:solutions}:\\\\x_1=\frac{-\left(-24\right)+8\sqrt{3}}{2\cdot \:12},\:x_2=\frac{-\left(-24\right)-8\sqrt{3}}{2\cdot \:12}\\\\x =\frac{3+\sqrt{3}}{3},\:x=\frac{3-\sqrt{3}}{3}\\\\x=1.57735\dots ,\:x=0.42264\dots[/tex]
So we approximate the side lengths to be 1.6 and 0.4 respectively. But when we plug in 1.6 for x, we get the volume as negative. Therefore x has to be 0.4.
Side lengths: 0.4, 4-2(0.4) => 3.2, 2-2(0.4) => 1.2
It’s x+8 at the bottom but if you solve this please give me a step by step so I know how to solve it, thank you!!♥️
Answer:
x=4.
Step-by-step explanation:
Let's solve your equation step-by-step.
5/15=x/ x+8
Step 1: Cross-multiply.
5/15=x/ x+8
5*(x+8)=x*(15)
5x+40=15x
Step 2: Subtract 15x from both sides.
5x+40−15x=15x−15x
−10x+40=0
Step 3: Subtract 40 from both sides.
−10x+40−40=0−40
−10x=−40
Step 4: Divide both sides by -10.
−10x−10=−40−10
Then your answer will be x=4.

which images shows a reflection
I'll Give You Some Hints:
Let's Look at C.
In C, the triangle is translated 2 units to the right. Which means that it cannot be a reflection.
Let's Look at B.
In B there is a sideways triangle. That means it's a Rotation. Which means it's not Reflected.
Lastly, Let's Look at A.
To get from the original triangle to the triangle in A, you have to reflect twice. Once along a vertical line, and then along a horizontal line.

Answer:
Your answer is
∠MHJ = 50°
Mark my answer as brainlist . I need that urgently . Folow me for more answer.
Step-by-step explanation:
The measure of angle ∠MHJ is 35.
Option A is the correct answer.
What are corresponding angles?The angles that are in the same position on a given two parallel lines intersected by a transversal line are called the corresponding angles.
Corresponding angles are always equal.
We can also have alternate angles which are always equal.
We can also have alternate interior and exterior angles which are equal.
The angles on the same side make upto 180 degrees
We have,
From the figure,
We can see that,
(2x - 20) and (x + 15) are opposite angles.
So,
2x - 20 = x + 15
2x - x = 15 + 20
x = 35
Thus,
The measure of angle ∠MHJ is 35.
