Kelly's art teacher asked him to draw a rectangle with a length of 6 inches and a width of 10 inches. After Kelly does so, his teacher changes her mind and asks him to draw a proportional rectangle that has a length of 9 inches. How many inches wide is the new rectangle?

15

Step-by-step explanation:

It’s pretty simple!

So first we set up the proportion, 6:10

We know that 3 is a common factor for 6 and 9, so we divide 6 by 2 and 10 by 2 and get the proportion 3:5, now we multiply both numbers by 3,

9:15!

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

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
