In total, they would need 4 pumps. If we divide 55 by 17, we get just more than 3. This little more would need an entire pump. So the answer 4 total, 3 added
Sum of interior angle of polygon: S = (n-2) * 180°,
where n is number of sides and where S is total degrees.
With 6 sides, n = (6-2)*180 = 720°
Then set all of the interior equations equal to the sum, or
720 = 5x + 4x+2 + 5x+6 + 2x-2 + 3x+5 + x-10
720 = 20x + 1
719 = 20x
x =
= 35.95
Customer have to drive 100 miles for cost to be equal to $140
<u>Solution:</u>
Given function is as follows
C = 120 + 0.20m
Where "C" represents cost in dollar of renting a car and "m" represents number of miles.
If we see the given equation, we can say that fixed cost is 120 and variable cost is 0.20m which is dependent on number of miles car is driven.
We need to calculate number of miles so that total cost that is C = $140
On substituting C = $140 in given function, we get
140 = 120 + 0.20m
On Solving above equation for m we get
140 – 120 = 0.20m
=> 20 = 0.20m
=> 
Hence customer have to drive 100 miles for cost to be equal to $140.
