C.

Step-by-step explanation:

65% means 65 out of 100, or 65/100.

65% of 90 is an unknown number, x.

65 is to 100 as x is to 90.

65/100 = x/90

Answer is C.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
