Michael has a set of 24 math problems to do for homework. Michael completed 1/4 of his homework in 3/4 of an hour. If he continues at this rate , what fraction of his homework would he complete in one hour ? A. 3/8 B. 2/3 C. 4/3 D. 3/2

Given:

Total number of problems = 24

Michael completed of his homework in of an hour.

To find:

What fraction of his homework would he complete in one hour.

Solution:

We have,

Part of work done in of an hour

Part of work done in an hour

Therefore, he complete of his homework in 1 hour. Hence, all options are incorrect.

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
