Answer:
interest rate is 38.68 %
Step-by-step explanation:
Given data
installment = $60
time = 36 months = 36/12 = 3 years
principal = $1000
to find out
interest rate
Solution
we know student pay $60 for 36 months
so he pay total = 60 × 36 = 2160
total amount pay by student = $ 2160
so we can find interest rate by given formula
rate = (1/time)(amount/Principal - 1)
put the value time amount and principal here
rate = (1/3)(2160/1000 - 1)
rate = 0.386667
interest rate is 38.68 %
The expression equivalent to 4^-5 • 3^-5 is 12^-5
<h3>What are equivalent expressions?</h3>
Equivalent expressions are simply known as expressions with the same solution but different arrangement.
Given the index expressions;
4^-5 • 3^-5
Using the exponent rule, the two values are have different bases but the same exponent and thus, we multiply the bases and leave the exponents the same way.
This can be written as;
4(3) ^ -5
expand the bracket
12^-5
Thus, the expression equivalent to 4^-5 • 3^-5 is 12^-5

Answer:
Perimeter = (Length x 2) + (Width x 2)
27.5 = (9 x 2) + (Width x 2)
27.5 = 18 + (Width x 2)
9.5 = (Width x 2)
4.75 = Width
check:
27.5 = (9 x 2) + (4.75 x 2)
27.5 = 18 + 9.5
27.5 = 27.5
Since the width is 4.75 and the length is 9, we can multiply the two to get the area. 4.75 x 9 = 42.75 sq. ft.
