2.) Given: There are 30 students. 24 are wearing sneakers.

Work: We can figure this out by finding the exact percentage of sneaker-wearers in the class.

To find the percentage, you do 24/30. 24/30 is equal to 80%.

Answer: Joe is wrong. The percentage of students wearing sneakers is 80% and not 70%.

3.) Given: There are 40 people total. 2 women per 3 men.

Work: 2:3 women to men

If we multiply both by 10, we will get 50 people in total.

20:30 = 50

So we need to shrivel this down to 40 by taking out 5 on both sides of the ratio.

50 - 5 - 5 = 15:25 = 40

But the ratio need to be divisible by 2 because of the 2 women that are needed per 3 men. We can do this by moving over one human to the men’s side.

There are 14 women and 26 men. I didn’t use any of the strategies there listed because I don’t even remember what those are. I’m in grade 9. I would say that the ratio table works best because I just used ratios...

4.) Given: Find simplified fraction of silicon. 100%.

Work: Add all things up to find out the denominator for the fraction. They will equal 100.

So the fraction is 28/100.

We can divide this fraction by 4.

7/25

This is the simplified form.

Answer: 7/25

The scatter plot shows the maximum noise level when different numbers of people are in a stadium. The linear model is given by the equation y=1.5x + 22.7 where y represents maximum noise level and x represents the number of people, in thousands, in the stadium.

1. The slope of the linear model is 1.5. What does this mean in terms of the maximum noise level and the number of people?

2. A sports announcer states that there are 65,000 fans in the stadium. Estimate the maximum noise level. Is this estimate reasonable? Explain your reasoning.

3. What is the -intercept of the linear model given? What does it mean in the context of the problem? Is this reasonable? Explain your reasoning.

Find the area...

A. 54 sq in
B. 60 sq in
C. 72 sq in

Answers

A. 54 sq in

6 in. times 9 in. = 54 sq in

Answer:

60 sq inches

Step-by-step explanation:

Okay, here we are given two different shapes. One being a rectangle, and the other being a triangle. We are trying to find the area of the two shapes combined and in order to do so here are the steps:

The area of a rectangle is as follows:

[tex]b*h=A[/tex]

The area of a triangle is as follows:

[tex]A= \frac{1}{2} b*h\\or \\A=\frac{b*h}{2}[/tex]

Note: Notice how rectancgles have coensideing sides. Meaning that the opposite side of 9in will be 9 in and the opposite side of 6 in will be 6in.

Now lets solve the problem:

[tex]b*h =A\\6*9=54 sq inches\\A=\frac{1}{2} b*h\\A=\frac{1}{2} 6*2\\A=\frac{1}{2}(12)\\A=6 sq inches\\6+54=60 sq inches[/tex]

What does the word "flip" tell you to do in "Keep, Change, Flip" for dividing fractions?
A
change the places of the numbers in the numerator and the denominator for the first fraction
B
change the places of the numbers in the numerator and the denominator for the second fraction
C
change the places of the numbers in the numerator and the denominator for both fractions
D
change the division sign between the fractions

Answers

Answer: It is C.

Step-by-step explanation:

When you are dividing fractions, you should always flip the numerator and denominators for the second fraction. After flipping the second fraction, you should multiply the first fraction and the second fraction together.

Example: 1/3 divided by 2/5= 1/3 x 5/2= 5/6
