Barbed wire is sold in 80-rod rolls. How many feet are in 16 rolls of barbed wire?
(Note: 16.5ft = 1 rod)

answer:

21,120 feet

Step-by-step explanation:

16.5 ft x 80 rods = 1,320 ft of wire in each roll

1,320 ft x 16 rolls = 21,120 ft of wire in 16 rolls

positive

step-by-step explanation:

the quadrant is facing upwards

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
