Use the equation for volume of a pyramid (base x width x height)
Answer:
$90
Step-by-step explanation:
Given from the question that the down payment is 10% the selling price of the store this will be;
10/100 * $2445 = $244.50
Monthly payments = $195
For one year, paying $195 per month will give a total of : $195 * 12 =$2340
Adding the down payment to get total amount paid = $2340 + $195 = $2535
The interest paid will be : $2535 -$2445 = $90
Pretty sure that you got it right..
Answer:

where R is the R-value and t is the thickness in inches.
Step-by-step explanation:
We are given the following in the question:
The R-value of fiberglass insulation and f its thickness have a linear relation.
Let R be the R-value and t be the thickness. Then, the equation can be written as:

where a and b are constants.
When t = 3.5, R = 11

When t = 6, R = 19

Solving the two equation, using the elimination method, we have,

Thus, the linear relationship is given by:

where R is the R-value and t is the thickness in inches.
