Answer:
First, we need to know how to calculate the area and the permiter of a rectangle.
To calculate the area, we multiply base by height and to calculate the perimeter, we sum all sides.
Knowing this, we can say that the area is 3x * (x+5) and the perimiter is 3x + 3x + x + 5 + x + 5, as we know both are the same, we write it as an equation:
Now we solve the equation:
As the negative result doesn't have sense, we only pick the second one: 1.
If x = 1, then area would be 3*6 = 18 square inches and perimeter 3+3+6+6 = 18 inches
Answer:
The monthly payment will be $531.12
Step-by-step explanation:
Consider the provided information.
After paying $5,000 down payment you need to pay:
$29,000-$5,000=$24,000
APR is 2.99% or APR = 0.299%
Therefore, 
n = 48
We can calculate the monthly payment by using the formula:
Where P is the monthly payment, PV is the present value, r is the rate per period and n is the number of period.
Substitute the respective values in the above formula we get,
Hence, the monthly payment will be $531.12
Answer:
D. Obtain a cluster sample by randomly selecting 20 counties and visiting every restaurant within those counties.
Step-by-step explanation:
Since this executive wants to minimize cost and expenses he should use a cluster sample of 20 counties and using the selected counties as a representative of the whole. Cluster sampling is a good and useful way of doing market research. It is more economical than other sampling methods and as the executive cannot get information on the whole population, he would be able to get information from the clusters.
