Mathematics

since its 2 half circles calculate are for a circle would be area = piR^2

 the diameter is 100 feet so radius would be 100/2 = 50 feet

 using 3.14 for pi you get 50^2 x 3.14 = 7850 square feet for the circle area

 rectangle area = l x w = 100 x 212 = 21200

 now add them

21200 + 7850 = 29050 square feet

5 can go into 10 and 20 so you just want to divide them by five which gives you 
2/4.

its still not simplified yet so 2 can go in to 2 and 4 so we divide them your answer should be 1/2

so your simplified answer for 10/20 is 1/2

so 10/20=1/2

same thing for 30/60

10 can go into 30 and 60 so we divide them by 10

you should get 3/6

its still not simplified 

3 can go into 3/6 so we divide them by 3

you should get 1/2

 so 30/60= 1/2




10/20 = 1/2. 

30/60 = 1/2



so your simplified answer for both of them is 1/2





I hope this helped!

ICE Princess25 [194]

Answer:

x = 49

Step-by-step explanation:

AD is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides , that is

\frac{28}{x} = \frac{8}{14} ( cross- multiply )

8x = 392 ( divide both sides by 8 )

x = 49

PolarNik [594]

Answer:

Step-by-step explanation:

First, replace f(x) with y . ...

Replace every x with a y and replace every y with an x .

Solve the equation from Step 2 for y . ...

Replace y with f−1(x) f − 1 ( x ) . ...

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.
