The graph shows the amount of water being filled over time.
For each tank, explain whether or not there is a proportional relationship between the amount of water, in gallons, and the time in minutes. If there is a proportional relationship, identify the unit rate. Use specific features of the graph to support your answer.

50- 250 is correct i did that one too

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

: )

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
