We are given a rectangle with sides as indicated.
Required;
We are required to find the area and the perimeter from the dimensions provided.
Step-by-step solution;
We shall begin by reconstructing the rectangle and show the missing sides. This is done below;
Take note that we can extract one of the triangles and use the dimensions to calculate the missing side. This is also shown below;
Observe that we now have a triangle with sides 17 units and 16 units.
We draw a perpendicular and we effectively split the triangle into two right angled triangles. We can now solve for the side x using the Pythagoras' theorem.
[tex]\begin{gathered} c^2=a^2+b^2 \\ Where: \\ c=hypotenuse \\ a,b=other\text{ }sides \end{gathered}[/tex]We substitute these into the formula above;
[tex]\begin{gathered} 17^2=x^2+8^2 \\ \\ 289=x^2+64 \end{gathered}[/tex]Subtract 64 from both sides;
[tex]225=x^2[/tex]Take the square root of both sides;
[tex]\begin{gathered} \sqrt{225}=\sqrt{x^2} \\ \\ 15=x \end{gathered}[/tex]Let us now reconstruct the quadrilateral with the new dimension calculated.
We now have the Length and Width of the rectangle and we can now calculate the area and perimeter.

Answers
Let's begin by identifying key information given to us:
Amount invested (Initial Value) = $210 /acre
Gross income (Final Value) = $220 /acre
The percentage return is given by:
[tex]\begin{gathered} Return=\frac{FinalValue-InitialValue}{InitialValue} \\ Return=\frac{220-210}{210}=\frac{10}{210} \\ Return=0.04762\approx4.76\approx4.8 \\ Return=4.8\text{\%} \end{gathered}[/tex]Therefore, the return on investment is 4.8%

A car with a 15-gallon gas tank can go 22 miles on 1 gallon of gas. If the tank is full at the beginning of a 377-mile trip, how many times does the driver have to refill the gas tank?
Answers
Consider that the car can go 22 miles on 1 gallon of gas, therefore the amount of gas required for the 377 mile trip is calculated as,
[tex]\frac{377}{22}\approx17.136[/tex]So the car needs 17.136 gallons of gas to complete the trip.
Since the capacity of the tank is 15 gallons, so the driver has to fill the tank two times.
First time for the full 15 gallons refill, and the second tme for the remaining 2.136 galllons fuel refill.
Thus, the driver has to refill the gas tank 2 times, to complete the trip.

o points earned 21 Sally borrowed $500 to help pay for a car repair. The interest rate is 16% and the length of the loan is 30 months. How much money will Sally owe in total at the end of 30 months? Do not enter any spaces.
Answers
Answer:
$700
Explanation;
Givern the following
Amount borrowed = $500 (Principal)
Rate = 16%
Time = 30months = 30/12 yrs
Get the interest
Interest = PRT/100
Interest = 500*16*30/12*100
Interest = 5*16*30/12
Interest = $200
Amount owed at the end of 30months = Principal + Interest
Amount owed at the end of 30months = $500 + $200
Amount owed at the end of 30months = $700
There are 15 members of the show choir. In how many different ways can you arrange any 8 members in the front row?
Answers

.
The eighth chair can be any of 8.
For each of those ...
Number of ways to fill the 8 chairs = (15 x 14 x 13 x 12 x 11 x 10 x 9 x 8) = 259,459,200
But in each group of 8 people you can sit on (8 x 7 x 6 x 5x 4 x 3 x 2 x 1) = 40,320 orders.
So each group of 40,320 people is represented 24 times out of 259,459,200
Therefore, the answer is:

Percentage of commission = 10.5%
per week paid = $495.50
a. Equation of Michelle paid = 10.5/100X + 495.50
b. The total value of the kayaks she sold was $19 425.

Problem 7:
We determine the time as follows:
*We can proceed using the following expression:
[tex]t=\frac{\ln (\frac{m}{p})-\ln (\frac{m}{p}-\frac{r}{n})}{n\ln (1+\frac{r}{n})}[/tex]Here, t is the time it will take to pay, m is the maximum she can afford to pay each month, p is the base loan value, r is the interest rate, n is the number of periods. Now we replace:
[tex]t=\frac{\ln(\frac{500}{20000})-\ln(\frac{500}{20000}-\frac{0.071}{12})}{12\ln(1+\frac{0.071}{12})}\Rightarrow t\approx3.8[/tex]So, she will take approximately 3.8 years to pay up the loan.
Problem 8:
We determine the time he has as follows:
We use the expression:
[tex]t=\frac{\ln (\frac{m}{p})-\ln (\frac{m}{p}-\frac{r}{n})}{n\ln (1+\frac{r}{n})}[/tex]Here, t is the time it will take to pay, m is the maximum he can afford to pay each month, p is the base loan value, r is APR, n is the number of periods. Now we replace:
[tex]t=\frac{\ln(\frac{400}{14000})-\ln(\frac{400}{14000}-\frac{0.068}{12})}{12\ln(1+\frac{0.068}{12})}\Rightarrow t\approx3.3[/tex]So, he will take approximately 3.3 years to pay the loan.
Problem 10:
We determine the amount he will have to pay as follows:
*We use the following expression:
[tex]V=P(1+n)^t[/tex]Here V is the value to obtain, P is the original amount, n is the interest rate and t is the number of periods, now we replace:
[tex]V=(22000)(1-0.0485)^{15}\Rightarrow V\approx44766.09[/tex]So, after 15 years he will have to pay approximately $44766.09.

[tex]\begin{gathered} m\angle1+m\angle4=180\rightarrow \\ 10x+2+5x+13=180 \\ 15x+15=180 \\ 15x=165 \\ x=\frac{165}{15}=11\rightarrow \\ m\angle1=10\cdot11+2=112 \end{gathered}[/tex]
