Need help on this question on compound shapes
1 answer:
9514 1404 393
Answer:
468 square inches
Step-by-step explanation:
The way dimensions are labeled on the figure suggests a simple division and easy calculation.
Left part: 17 in by 16 in. A= LW = (17 in)(16 in) = 272 in^2
Right part: 14 in by 14 in. A = LW = (14 in)(14 in) = 196 in^2
__
Total area = left part + right part
Total area = 272 in^2 + 196 in^2 = 468 in^2

Answer:
He should pay $2,790.7.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time, in years.
After t years, the total amount of money is:
In this question:
Rate of 10%, so I = 0.1.
9 months, so
How much should he pay for a note that will be worth $3,000 in 9 months?
We have to find P for which T = 3000. So
Then
He should pay $2,790.7.
