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.

On a highway, you take 3 seconds to increase your speed from 32 to 35 miles per hour. Your speed increases the same amount each
balandron [24]

Answer:

1 to 30 seconds

Step-by-step explanation:

3 seconds increases your speed from 32 to 35 miles per hour

Hence 3 seconds = 3 miles per hour(35-32 miles)

1 second = 1 mile

The function for the increase per mile is therefore:

f(x)= 1x

Where x is number of seconds travelled on the highway

The domain of a function are the possible input values for x. Since the speed limit on the highway is 65 miles, the input values for x cannot be more than 30 seconds(current speed is 35 miles per hour, 65-35=30)
