PLEASE HELP ME I NEED TO DO THIS BEFORE I GO TO SLEEP AND I AM SOOO TIRED AND DO NOT UNDERSTAND HOW TO DO THIS.

Ok so, here goes:
simple interest: r- rate, A- amount in the end, t- time, P- principal
<span>r = (1/t)(A/P - 1)
</span>Putting in our numbers
r = (1/4)((21236/5309) - 1) = 0.75
r = 0.75

Converting r decimal to R a percentage
R = 0.75 * 100 = 75%/year

The interest rate required to get a total amount, principal plus interest, of $21,236.00 from simple interest on a principal of $5,309.00 over 4 years is 75% per year.

fence is to be built to enclose a rectangular area of 250 square feet. The fence along three sides is to be made of material tha
Morgarella [4.7K]

Answer:

23.05 x 10.85

Step-by-step explanation:

Area of Rectangular Fence = L * W = 250ft^{2}

L * W = 250

W = \frac{250}{L}                                      ................................... (i)

Perimeter = 2L + 2W

Three sides cost 4 dollars per foot = 4(2L) + 4W

(The two lengths must be constructed with the 4 dollars materials)

Fourth side costs 13 dollars per foot = 13W

Cost = 4(2L) + 4W + 13W

C = 8L + 17W                         ...................................... (ii)

Substitute (i) into (ii)

C = 8L + 17 (\frac{250}{L})

C = 8L + \frac{4250}{L}  

Plotting this equation with L on the x-axis and cost on the y-axis

minimum cost will be when L ≈ 23.05 ft

W = \frac{250}{23.05} ≈ 10.85 ft

minimum cost = 8(23.05) + \frac{4250}{23.05}

minimum cost = 184.4 + 184.382

minimum cost ≈ 368.78 dollars
