Answer:

Step-by-step explanation:
We have given:
Principal amount which is 80,000
Time which is 20 year
Rate which is 11.5%
And since, we have to find 13 years early so, time would be: 20-13=7 years.
And since, we have to find for 12 months
Hence, n=12
We have formula to calculate compound interest:

On substituting the values we get:


On simplification we get:

Answer:
5
Step-by-step explanation:
2x + 5 = 10
you minus the 5
2x = 5
you divide both sides by 2
x = 5
The surface area of the rectangular prism is 3668.94 m²
<h3>Calculating Surface area </h3>
From the question, we are to determine the surface area of the rectangular prism
Surface area of a rectangular prism is given by the formula,
Surface area = 2(lw + lh + wh)
Where l is the length
w is the width
and h is the height
From the given diagram,
l = 35.7 m
w = 25.5 m
h = 15.1 m
Putting the parameters into the formula, we get
Surface area = 2(35.7×25.5 + 35.7×15.1 + 25.5×15.1)
Surface area = 2(910.35 + 539.07 + 385.05)
Surface area = 2(1834.47)
Surface area = 3668.94 m²
Hence, the surface area of the rectangular prism is 3668.94 m²

Answer:
<em>The salesperson needs to sell 10 stereos to make the same money on both plans</em>
Step-by-step explanation:
We'll analyze both choices for the compensation plans of a salesperson.
One plan offers a fixed weekly salary of $250 plus a $25 commission for each stereo sold. The function than models this plan is:
P1=250+25x
Where x is the number of stereos sold.
The other plan offers no fixed salary but a $50 commission on each stereo sold. The function of this plan is:
P2=50x
To find the equilibrium point for both plans, we make P1=P2:
250+25x=50x
Simplifying:
25x=250
Solving:
x = 250 / 25 = 10
The salesperson needs to sell 10 stereos to make the same money on both plans
