Answer:
16.8
Step-by-step explanation:
A = pi * r^2
<span>A = 3.14 * 50^2 </span>
<span>A = 7,850 square miles (area of the 50 mile broadcast signal)
A = pi * r^2
A = 3.14 * 75^2
A = </span>17,662.5 = 17,663 square miles (area of the 75 mile relayed signal)
Now we just need to subtract the 50 mile signal from the 75 mile signal, so:
17,663 - 7,850 = <span>9,813 square miles greater
Hope this helps :)

Answer:
There are 36 boys
Step-by-step explanation:
This is how you do it!
So, There is a ratio of 1:2 for the orange to green.
This means that e can write an equation like this:
Let x be the orange picks
x + 2x = 12
3x = 12
x = 4
This means that there are 4 orange picks, and also 8 green picks
Now we can check that by simplifying the ratio --> 4:8 = 1:2
Therefore, your answer would be 8 green picks
Hope this helped!
Answer:
Option c
Step-by-step explanation:
A system of equations are given to us. And we need to solve them . The given system is
We numbered the equations here . Now put the value of equation 1 in equation 2 that is substituting y = 2x - 3 in eq. 2 .
We got two values of x as 0 & 2 . Alternatively substituting these values we have ,
Thefore the required answer is ,
