<span>A
tank can hold 15 gallons to be considered as full tank. Currently, the tank has
12 gallons on it. Find the percentage of its current gas.
Let x be the value of the percentage that we are looking:
=> 12 = x * 15
=> 12 = 15x
Now, let’s divide both sides with 15.
=> 12 /15 = 15x / 15
=> 0.8 = x
Now, we have the decimal value of our percentage, let’s convert it to
percentage
=> 0.8/100
=> 80%, thus x = 80%

9 sides
Method 1: Since the interior angle 140 degrees, the supplement of this is the exterior angle and equal to 40 degrees. Hence the number of sides is 360/40 = 9 sides.
