Please help me!! Amy has 18 marbles. Four of her marbles are red and the rest are black.
What is the ratio of the number of black marbles to the number of red marbles?

14:4

Step-by-step explanation:

First u would find how much black are left then u would put it in a ratio black to red which is what I put up there

17   x 256=4352

sorry if this is wrong, i'm new.

step-by-step explanation:

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
