10. A student studied 18 hours in 7 days, if he wants to study average 2 hours each day for 14 days. How many hours he needs to study for next 7 days

14 hours, you just need to multiply your average with the next 7 days and it will be 14 hours.

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
