Leah practices dance for 2 hours each week. her younger sister sonia practices dance for 0.8 the amount of time leah practices.

1.6 hours

Step-by-step explanation:

Leah practices dance for 2 hours each week.

Her younger sister Sonia practices dance for 0.8 the amount of time Leah practices.

The time of practice by Sonia = 0.8 of 2 hours

= 0.8 × 2

= 1.6 hours

Converting 1.6 hours to hours and minute.

1 hour (0.6 × 60) 36 minutes

Sonia practices dance for 1 hour 36 minutes each week.

i would say c is the best answer, hope it's right!

good luck! =)

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
