A 2-yard piece of ribbon costs $41.28. What is the price per foot?

$61.92

Step-by-step explanation:

a yard is 1/3 of a foot

2 yards = $41.28

which means that 1 yard = $20.64

3 yards = 1 foot

so 1 foot of ribbon =

$20.64 x 3 = $61.92

hope this helps :)

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
