2 2/5 in kilometers in 3 3/4 minutes unit rate

Mathematics
1 answer:
Mars2501 [29]3 years ago
5 0

Answer:

Step-by-step explanation:

d = r * t     Divide both sides by t

r = d / t

d = distance = 2.25 km

t = time = 3 3/4 minutes = 3.75 minutes

r = 2.25 / 3.75

r = 0.6 km / minute

r = 3/5 km / minute

If the units are different than those given, please state them underneath my answer. I'll get to it as soon as I see your comment.

What is the slope of the line that passes through the points (-8, -3) and
aleksklad [387]

Answer:

slope of the graph is

\frac{ - 1}{4}

Step-by-step explanation:

slope of a graph = (y2 - y1) / (x2 - y1)

  • 1 - (-3) / ( -24 - ( -8 ) )
  • 1 + 3 / -24 + 8
  • 4 / -16
  • 1 / -4
  • -1 / 4

hence the slope of the graph is

\frac{ - 1}{4}

Chris purchased a used car for $19,700. The car depreciates exponentially by 10% per year. How much will the car be worth after
Monica [59]

Given: Purchasing value of car = $19,700,

                 Rate of depriciation = 10% per year.

To find:  Final value of car after after 6 years.

Solution : Because rate of car is being depriciated exponential. So, we would exponential formula.

A = Pe^{-kt}.

Where, P is the purchase value, k is the rate of depriciation and t is the number of years.

Plugging values P = 19,700, r=10% that is 0.10 and t= 6 in above formula.

A= 19,700e^{-0.10*6}

A= 19,700e^{-0.60}

A= 19,700 (0.54881163609)

A= 10811.5892311.

Rounding to the nearest penny (two decimal places0.

A= 10811.59.

Therefore, Final value of car after after 6 years = $ 10811.59
