Hey how do you know of can run 1/4 of a mile in 22.5 seconds. at this rate, which equation can be used to determine how fast a hyena runs in miles per hour? a. 1/4 divided by 22.5 = 40 b. 22.5 divided by 1/4 = 40 c. 1/4 divided by 22.5 = 90 d. 22.5 divided by 1/4 = 90

D

Step-by-step explanation:

If its 1 quarter of a mile in 22.5, then we take s, seconds, times 4 which is 90.

SO we cross out A and B, and we're left with C AND D.  Now we check the math on them.

.25/22.5 is 0.01111111 (repeating)

and 22.5/.25 is 90!

126 maybe. sorry

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
