The unit rate would be $0.37
21 divided by 7 = 3
so that means 3 x 4 is 12

Explanation:
The formula for calculating the distance between two points is:
d
=
√
(

Substituting the values from the points in the problem gives:
d
=
√
(

Or
d
=

rounded to the nearest thousandth.
Or
d

Answer:
I'll give it straight: the following are rational numbers.
- Whole numbers
- Terminating decimals
- Repeating decimals
- Improper fractions (and all other fractions)
- (Integers, too)
- If square root is whole number, square root of a square is perfect, and therefore, rational
- Since a rational number is any number that can be written as a fraction, if a mixed number, such as 1 1/2, can be written as a fraction, then it is rational (1 1/2 can be written as 3/2, therefore it is rational)
