You use the Pythagorean theorem which is a^2+b^2=c^2
So....
.8^2+.6^2=c^2
.64+.36=c^2
1=c^2
1=c becaaue the square root of one is one
Since 60 minutes are in 1 hour, we can do (0.08 km/1 min)*(60min/1 hour) and cross out the minutes, getting (0.08*60 km)/(1 hour)= 4.8km/1 hour. Since 1.61 kilometers are in 1 mile, we can multiply the equation by 1mile/1.61 km (since they are equal) and cross out the km to get 4.8*1.61miles/1 hour= \
7.728mi/1 hour. Since it's closer to 8 than 5, 3, or 2, D is right
Answer:
a. Total cost of the principal = $217,411.20
b. Interest for the mortgage loan = $104,911.20
Step-by-step explanation:
Total cost of the principal = Monthly payment * Number of years * Number of months in a year = $603.92 * 30 * 12 = $217,411.20
Total cost of the principal of the loan includes the mortgage loan amount and the interest for the mortgage loan. Therefore, the interest for the mortgage loan can be calculated as follows:
Interest for the mortgage loan = Total cost of the principal - Mortgage loan amount = $217,411.20 - $112,500 = $104,911.20
