Given:
Principal amount = $28,000
Time period = 9 years
Interest rate = 3.25
Required:
Find the total amount at the end of the period.
Explanation:
The amount formula when the interest is compounded annually is given by the formula:
[tex]A=P(1+r)^{nt}[/tex]Where P =principal amount
r = rate of interest
T = time period
n = Number of time
Substitute the given values in the amount formula.
[tex]\begin{gathered} A=28,000(1+0.0325)^9 \\ A=28,000(1.33355) \\ A=37,339.51 \\ A=37,340 \end{gathered}[/tex]Final Answer:
Thus the amount after 9 years is $37,340.
1,1,2,2,2,5,5,8,9,10,11
In order to calculate the median the data should be arranged in order from least to greatest.
According to this question we have the following number:
1,1,2,2,2,5,5,8,9,10,11
So, we would proceed to arrange the number as follows:
1, 1, 2, 2, 2, 5, 5, 8, 9, 10, 11
As we have a total of number of 11, then that means that the median would be the central score of it.
Therefore, in this case the central score
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?
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.

If a savings account of $19,400 is compounded semiannually at 5,07% annual interest, how much will the account be worth in 32 months? Round your answer to thenearest cent, if necessary. Note: 365 days in a year and 30 days in a month.
From the question, we are provided with the following information:
[tex]\begin{gathered} \text{Principal, P=\$19,400} \\ \text{Rate, r=5.07\%} \\ r=\frac{5.07}{100}=0.0507 \\ \text{Time, t(in years)=}\frac{32}{12}=2.67years \\ N\text{umber of times interest applied per time period, n=2(semi-annually)} \end{gathered}[/tex]The required parameter we are to find is the Amount, A.

Samuel invested $210 per acre for seed, fertilizer, fuel, depreciation, and land use. If he grosses$220 per acre this year, what percent return does he earn on his investment?
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%
Find the circumference of a circle with an area of 95.03 m^2. Round the answer to the nearest tenth.
The area of a circle with radius r is given by the following formula:
[tex]A=\pi r^2[/tex]The circumference of that circle is given by:
[tex]C=2\pi r[/tex]Finding the answerWe are given the area of the circle. With this data and the first formula we can construct an equation for the radius r. Once we find the radius of the circle we can use it to find its circumference. So first of all we take the first formula and we equalize it to 95.03:
[tex]95.03=\pi r^2[/tex]We can divide both sides by π:
[tex]\begin{gathered} \frac{95.03}{\pi}=\frac{\pi r^2}{\pi} \\ r^2=\frac{95.03}{\pi} \end{gathered}[/tex]Now we apply a square root to both sides:
[tex]\begin{gathered} \sqrt{r^2}=\sqrt{\frac{95.03}{\pi}} \\ r=\sqrt{\frac{95.03}{\pi}} \end{gathered}[/tex]And that's the radius of the circle. Then we can use this value in the formula of the circumference C:
[tex]C=2\pi *\sqrt{\frac{95.03}{\pi}}=34.6[/tex]AnswerThen the answer is 34.6 m.

answer is 1/25Reasoning Use the Distributive Property to solve the equation below. Use pencil and paper. Explain why the Distributive Property makes it possible to solve this equation. 44 - (2c + 3) = 4(C+5) + C The solution of the equation is
ANSWER and EXPLANATION
The distributive property involves simplifying expressions to make them easier to solve.
It is possible to solve the equation with distributive property because it allows us to break down equations into simpler forms of addition or subtraction.
The equation we are given is:
44 - (2c + 3) = 4(c + 5) + c
Using the distributive property, we have:
44 - 2c - 3 = 4c + 20 + c
Collect like terms:
-2c - 4c - c = 20 - 44 + 3
-7c = -21
Divide through by -7:
c = -21 / -7
c = 3
The equation has been solved.

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.
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

For each of those ...
The second chair can be any of the 14.
For each of those ...
And so on until choosing 8 chairs
.
.
.
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:
[tex]\frac{259459200}{40320}=6435[/tex]6435 sets of 8 members, in any order.

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.
