The gas tank of your car is 40% full. There are 8 gallons of gas in the tank. What is the capacity of the gas tank?
andreyandreev [35.5K]
Percentage by which the gas tank of the car is full = 40%
Amount of gas in the gas tank = 8 gallons
Let us assume the capacity of the gas tank = x gallons
Then
40% * x = 8
(40/100) * x = 8
4x/10 = 8
4x = 8 * 10
4x = 80
x = 80/4
   = 20 gallons
So the total capacity of the gas tank of the car is 20 gallons. I hope the procedure is clear to you.

Which is not a solution of sin 20 = 1?<br> A = 90<br> B = 45<br> C = 225<br> D = - 135
koban [17]
If you plug in 90 into theta, the expression becomes sin(180), which has a value of zero. Therefore 90 cannot be a solution to this equation. Hope this helps.
