Okay to find the percent version of 0.624 you multiply by 100. 0.624×100=62.4%. Now as a fraction the last number behind the decimal is in the thousandths place so put 624 over 1000. 624/1000 simplified it would be 78/125
Answer: 
Step-by-step explanation:
Answer:
Not proportional.
Step-by-step explanation:
The butterfly method multiples it like a butterfly. Ex. 5 times 3 is 15. 8 times 2 is 16. Therefore, not proportional.
How To Find Inverses:
1. First, replace f(x) with y . ...
2. Replace every x with a y and replace every y with an x .
3. Solve the equation from Step 2 for y . ...
4. Replace y with f−1(x) f − 1 ( x ) . ...
5. Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
Area of square = 10x10
= 100
area of circle = pi(r)^2
= pi (5)^2
=25pi
area of shaded = 100 -25pi
circumference of circle = 2pi (r)
= 2pi(5)
= 10pi
perimeters of shaded = 10pi + 10 + 10
= 10pi +20
