So the distance formula is
. Using this, our equation is
and we can solve for it as such:

As we see with this radical, the sum that's under it is 15^2 + 8^2, or the third option.
13.8 gallons
Rounded from 13.8462
The equation you would use is (65/18)=(50/x) solve for x

Answer: 1</h3>
========================================================
Explanation:
Pick any two points you want from the blue line. I'll pick (0,1) and (1,2)
Apply the slope formula to those points
m = (y2-y1)/(x2-x1)
m = (2-1)/(1-0)
m = 1/1
m = 1
The slope is 1.
Notice how if we're at (0,1), then we move up 1 and over to the right 1 to arrive at (1,2).
slope = rise/run = 1/1
rise = 1, run = 1
