Answer: The driver has $95.25 after the last ride.
Step-by-step explanation: First we need to know how much money he recieved from each ride. Multiply 3.5 with each number.
$3.5 x 10 = $35
$3.5 x 5.5 = $19.25
$3.5 x 19 = $91
Now add them up.
$35 + $19.25 + $91 = $145.25.
However, he spends $50 on gas. So subtract $145.25 and $91.
$145.25 - $91 = $95.25.
Therefore, the driver has $95.25 after the last ride.
Answer: 800pi inches
=======================================
Explanation:
The formula to find the circumference of a circle is
C = pi*d
where
C = distance around the circle (aka circumference)
pi = 3.14 approximately
d = diameter
We know that the diameter of the wheel is d = 8, so
C = pi*d
C = pi*8
C = 8pi
is the circumference of the wheel
One full rotation will have the wheel cover a distance of 8pi inches. Imagine that wet paint is on the outer surface of the wheel. If the wheel is rolled out in a straight line, then the wet paint would cover a linear distance of 8pi inches along the flat ground. This is one full rotation, so 100 rotations covers 100*8pi = 800pi inches
Note: if we use pi = 3.14 as the approximation, then the hamster ran approximately 800*pi = 800*3.14 = 2512 inches if the wheel could move
I think it's $405 because that's the product of the decimal form of 13.5% (.135) and the amount loaned (3,000).
