Sorry to the people who were me earlier, but i actually don't get this one. i really need if anyone could with this. what is the reciprocal of 7/12? 1. -12/7 2.-7/12 3.7/12 4.12/7 if you could teach me about this that would be the best and you would be very and make my day!

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

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
