Answer:

0.9km/minute

or

54km/hour

Step-by-step explanation:

  • Average speed in km/minutes

18km in 20 minutes = 18km/20min

18km/20min = 0.9km/min

  • Average speed in km/hour

1 hour = 60 minutes

20 minutes = 20/60 = 0.3333 hours

18km/20mins = 18km/0.3333hours = 54km/hour

Answer:

All convert to terminating decimals.

Step-by-step explanation:

A decimal fraction will terminate if its denominator is a power of 2 or 5 or a product of such powers.

16 is the 4th power of 2, so all fractions that are some multiple of 1/16 will terminate.

If f(x)=-2x-3 find f(4)
Naddik [55]

Answer:

f(4) = -11

Step-by-step explanation:

Plug in 4 for x: Note that x = 4.

f(x) = -2x - 3

f(4) = -2(4) - 3

Remember to follow PEMDAS. First, solve the multiplication, then subtract:

f(4) = (-2 * 4) - 3

f(4) = (-8) - 3

f(4) = -11

f(4) = -11 is your answer.
