In a certain set of numbers, the ratio of integers to non integers is 2: 3. what percent of the numbers in the set are integers?
1) 20%
2) 33 1/3%
3) 40%
4) 60%
5) 66 2/3%

The relationship between related dataset can be represented in ratios and/or proportions using the ":" symbol. The percentage of integers in the set is 40%

To do this, we make use of the following representations:

integer

non-integer

So, we have:

The percentage of integers is calculated as:

This gives:

Hence, the percentage of integer is 40%

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
