Two cars, each with a different volume of gas in their tanks, start moving at the same time. However, the volume of gas in their tanks is used up at different rates. Assume the volumes are changing linearly. Volume in Tank (gal) Time (hr)15Car A17.2514.25Car B1915 How many hours will it take before both tanks have the same volume of gas in it?

8 hours

Step-by-step explanation:

−0.75x + 18 = -x+20

0.25x = 2

x = 8

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
