The Answer is C.) 9%

Step-by-step explanation: The first step is to divide the part by whole.

462/525, which equals 0.88. and then next multiply that by 100 to get the percentage  0.88*100 = 88. Just move the decimal 8.8% which rounds up to 9%.

Hoped this helped!!!

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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
