Answer:

1. 83 square inches

2. 7.065 square centimeters

Step-by-step explanation:

Hey there!

In order to find the area of the shaded region of the rectangle, you need to first find the area of the whole shape

The dimensions are 10 and 16 and if you multiply them together, you get 160

This means that the area of the whole shape is 160

Now they are asking for the area of the shaded shape, so we need to find the area of the white rectangle, and then subtract that area from 160

The dimensions for the white rectangle is 11 and 7

This means that the area of the white rectangle is 77

Now what we need to do is subtract 77 from 160

160-77=83

So the area of the shaded region is 83 square inches

Now to get to the second question

We need to find the area of the quarter circle

In order to find this, we need to first find the area of the whole circle, then divide that by 2

They gave us the radius already which makes it a lot easier (the radiues is 3)

All we need to do is input 3 into the formula for the area of a circle

\pi r^2

In this case, since they are telling us to use 3.14 as pi, the equation would look like this:

3.14*3^2

This can be simplified to 3.14*9 which is equal to 28.26

So this is the area of the whole circle

But the question is asking for the area of a quarter of that circle

So what we need to do is divide 28.26 by 4 which is 7.065

So the area of the quarter circle is 7.065 square centimeters

Emily made 75% of the baskets that she attempted if she may nine baskets how many attempts did you make?
Aneli [31]
Set up a proportion

75/100= 9 baskets/ x attempts

The ratio of numerator to denominator should be 75/100 which simplifies to 3/4. 3/4= 9/x
3*3=9, 4*3=12

x=12

Final answer: 12 attempts

I’d say it’s 2/1 since the rise is 2 and the run is 1 and slope I believe is rise/run. It’s been awhile So I’m not too sure this is the right answer. I hope it is.
