Four friends had dinner at a restaurant. the bill was $45.00 and they added a 20% tip. the four friends shared the total cost equally. how much does each person pay?

$13.50

Step-by-step explanation:

We can find the total bill here by multiplying $45 by 1.20, where the 0.20 represents the 20% tip:

1.20($45) = $54

Since the four friends agree to split the bill equally, each pays:

$54/4 = $13.50

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
