michael is paid $12.25 per hour. he worked 28 hours this week. he put 1/4 of his weekly pay in his savings account. how much did he have left?

257.25

Step-by-step explanation:

$12.25 * 28

=  343

343 / 4

= 85.75 (the amount he pays in his savings account)

So 3/4 of the total amount he have left

85.75 * 3

=257.25

12.25  ( 28) (3/4)   =  ???

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

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
