Answer:
25 in x 15 in
Step-by-step explanation:
Given:
- Length = 3/5 the width
- Area = 375 in²
Let width =
Therefore, length = 3/5
First create an equation for the area of the picture based on the given information for its width and length:
We are told the area of the enlarged picture is 375 in². Therefore, substitute this into the equation and solve for to find the width of the enlarged picture:
Therefore, the width of the enlarged picture is 25 in.
Substitute the found value of into the expression for length to find the length of the enlarged picture:
Therefore, the dimensions of the enlarged picture are <u>25 in x 15 in</u>. The width is 25 in and the length is 15 in, as the length is 3/5 of the width.

Step-by-step explanation:
The formula for compound interest, including principal sum is:
, where:
- A is the future value of the investment/loan, including interest
- P is the principal investment amount
- r is the annual interest rate (decimal)
- n is the number of times that interest is compounded per unit t
- t is the time the money is invested or borrowed for
∵ Phineas puts $800 into a certificate of deposit
∴ P = 800
∵ The rate of deposit is 3.39%
∴ r = 3.39% = 3.39 ÷ 100 = 0.0339
∵ The money is compounded monthly
∴ n = 12
∵ t = 3
- Substitute these values in the formula above
∴
∴
∴ A = 885.51407
- Round it to the nearest cent ⇒ hundredths place
∴ A = 885.51
