The answer is 270 degrees. 

Since a circle has a full degree measure of 360 degrees, we can multiply 360 by 3/4 to result in 270 degrees.

Hope this helps.

Question #7
Sever21 [200]

Answer:

The area is 56.7 square inches

Step-by-step explanation:

Given

See attachment for corner shelf

Required

The area

The corner shelf is a quadrant with radius;

r = 8.5in

The area of a quadrant is:

Area = \frac{\pi r^2}{4}

So, the area of the corner shelf is:

Area = \frac{\pi * 8.5^2}{4}

Area = \frac{\pi * 72.25}{4}

Area = \pi * 18.0625

Take \pi as 3.14

Area = 3.14 * 18.0625

Area = 56.7 -- approximated

Find the reciprocal of the expression. 10b/2b + 8
Alexus [3.1K]
Comment
I think you need brackets to clarify what you mean. I think it should be written as 
10b/(2b + 8) 

If that is the case the reciprocal is

(2b + 8)/10b You just turn everything up side down. There are technical ways of doing this, but the easiest way is just to do what I just did. 

Put the numerator in  the denominator,
Put the denominator in the numerator.

You could simplify this a bit.
2b/10b + 8/10b
which reduces further.

1/5 + 4/5b 
Just to make sure you understand where that b is, I will do this in

Latex.\frac{2b + 8}{10b} =  \frac{2b}{10b} +  \frac{8}{10b} =  \frac{2}{10} + \frac{4}{5b} =  \frac{1}{5} +  \frac{4}{5b}

Alternate answer
If you do mean what your wrote then the reciprocal is 2b / 10b + 8 which is 1/5 + 8 = 8 + 0.2 = 8.2 

The 8 has nothing to do with the reciprocal under these conditions.

The answer
I have given you all the choices I can think of without going into decimals. If you have choices, please list them under the comments.

Answer:

16

Step-by-step explanation:

Let the number be X

3/4 of X = 15

Multiplying out gives;

3X = 4x15

3X= 60

X = 20

Therefore, 4/5 of 20

Putting X = 20 we have;

4/5 x 20 = 16.

-------------------------------------------------

16-3/4= 15.25
