Answer:

B: It is a composite number.

Step-by-step explanation:

The number 143 is a composite number because 143 can be divided by one, by itself and by 11 and 13.

If you were to divide it by 11, you would get 13, and vise versa.

Jungkook walks 3 1/2 miles in 1 1/4 hours, what is the unit rate? I also want to know how do you find the unit rate?
geniusboy [140]
Hi there!
Unit rates are basically changes expressed as a quantity of one. For example, if we have something like 100 feet per second or 2 meters per hour, those are unit rates. In this case, we have a multiple-unit rate - 3 1/2 miles in 1 1/4 hours. First off, we need to simplify both fractions to an improper fraction, giving us 7/2 miles and 5/4 hours. Now, we need to divide 7/2 by 5/4.
7/2 ÷ 5/4
Find the reciprocal of 5/4:
7/2 × 4/5
Multiply:
28/10 → 2.8
Therefore, Jungkook walks 2.8 miles in one hour, or 2.8 mi/hour. Hope this helped!
