Sean organized his rubber duck collection in two rows on a shelf in his room. He put 14 rubber ducks in one row and the rest in a second row. If Sean has 29 rubber ducks in all, how many ducks did Sean put in the second row? Pick the diagram that models the story. Let d represent how many ducks Sean put in the second row.

15

Step-by-step explanation:

The answer is 15 because:

1st row: 14 rubber ducks

2nd row: d

We are trying to find d, and the simplest way to solve that is by subtracting.

29-14=15

So 15 ducks are on the second row.

d=15 rubber ducks.

definitely a. the others have almost all data points on one side of the line.

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
