Water flows into the tank at a rate of 3 litres per minute. If the tank fills completely in 450 seconds , What is the capacity of the tank in ml?

rate = 3l/minute÷60 = 0.05l/s

t = 450s

capacity = ?

rate = c/t

c = rate*t

c = 0.05*450

c = 22.5litres.

c = 22500ml

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

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
