The students in Ms. Baca’s art class were
mixing yellow and blue paint. She told them
that two mixtures will be the same shade of
green if the blue and yellow paint are in the
same ratio.
The table below shows the different
mixtures of paint that the students made.

A B C D E
Yellow 1 part 2 part 3 part 4 part 5 part
Blue 2 part 3 part 6 part 6 part 9 part

How many different shades of paint did the
students make?

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

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
