3. Identify the subsets of real numbers that apply to /100/5
Alina [70]

Using number sets, it is found that the correct classification of the number is:

C. rational number, integer, whole number, natural number , real number.

Numbers are classified as:

  • Whole, which is all positive numbers and zero, also called natural.
  • Integers, which is the set of whole numbers plus negatives.
  • Rational, which is the set of integer numbers plus terminating or repeating decimals.
  • Irrational, which are non terminating decimals.
  • Real, which are the sum of rational and irrational.

In this problem, the number given is:

\frac{100}{5} = 20

  • Which is a whole(natural) number, thus it is also integer, rational and real, and the correct option is C.

A cheetah ran 275 feet in 3.23 seconds. How fast did the cheetah run in miles per hour? Round your answer to the nearest whole m
yawa3891 [41]
First we convert feet into meters, since 1 feet is 0.3048 m: 275 feet * 0.3048 = 83.82m.

Then we do: 83.82m / 3.23s =  <span>25.9504644 m/s.

Then we convert that into miles per hour by </span>2.23694, so we do:

25.9504644 * 2.23694 = <span>58.0496318.

Then we round it to 58 mph.

So the answer is: The cheetah was running at 58 mph.

Hope this helped! c:</span>
