Amount of car loan taken by Scott = $5500
Amount of loan paid back by Scott = $7370
Then
Amount of money paid as interest by Scott = (7370 - 5500) dollars
= 1870 dollars
Then
Percentage of interest given for the car loan = (1870/5500) * 100
= 1870/55
= 34 percent
So Scott had to pay a total interest rate of 34% in the four years.I hope the procedure is simple enough for you to understand and solve future problems.
Answer:

Step-by-step explanation:
By the Pythagorean theorem, triangle BCD has

and triangle ABD has
.
Substituting the first equation into the second equation for
gives the equation

Now triangle ABC has

Expanding out the left side,
.
Now substitute the equation from before,
, into the new equation.


We work to isolate
by adding
to both sides of equation and subtracting
from both sides.

Divide both sides by 2 and you get 
Assume that x is positive and square root both sides to get the final result of

11% of 36278.13 is the same as .11 × 36278.13. The answer is 3990.5943
Your answer will be 12 since 8/8 is one whole and you need 12 so your answer is 12
