Will you be my boy.friend?

Step-by-step explanation:

-30%

Step-by-step explanation:

Use the above formula to find the percent change. So, replacing the given values, we have Percent change = [ (35 - 50) / 50] x 100 = -30 % (decrease) Where: 50 is the old value and 35 is the new value. In this case we have a % of decrease because the new value is smaller than the old value.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
