Online calculator to calculate the dimensions (length and width) of a rectangle given the area A and perimeter P of the rectangle. Then these equations are solved for L and W which are the length and width of the rectangle. Enter the perimeter P and area A as positive real numbers and press "enter".

A = L * W
A = 91
L = W + 6

91 = W(W + 6)
91 = W^2 + 6W
W^2 + 6W - 91 = 0
(W - 7)(W + 13) = 0

W - 7 = 0
W = 7

W + 13 = 0
W = -13.......extraneous solution...this one does not work

so the width is 7 inches <====
L = W + 6
L = 7 + 6
L = 13...and the length is 13 inches <====

If triangle RST and triangle XYZ are similar, which of these equations must be true?

Delicious77 [7]

Answer: A

Step-by-step explanation:

If they are similar, that means the proportions for corresponding sides will be the same.

I personally ignore the picture and use the labels of "triangle RST and triangle XYZ" that the problem gives because the XYZ picture is not lined up with the similarity it has with RST.

(A) says that side ST is corresponding with side YZ,

[] Triangle RST and triangle XYZ

-> Correct

(A) also says that side RT is corresponding with size XZ,

[] Triangle RST and triangle XYZ

-> Correct

This means that option A is the correct answer.

Jeff has been offered a new job which requires that he invests $100

hichkok12 [17]

Answer:

At the beginning of 6th month , Jeff will have in his account $ 520 .

Step-by-step explanation:

At the beginning of 6th month , Jeff will have in his account,

$ $( 100 \times (1 + 0.02\times 4) + 100 \times (1 + 0.02 \times 3) + 100 \times (1 + 0.02 \times 2) + 100 \times (1 + 0.02) + 100)$

= $ $(100 \times (5 + 0.02 \times (4 + 3 + 2 + 1)))$

= $ $(100 \times (5 + 0.02 \times 10))$

= $ $(100 \times 5.2)$

= $ 520

since, the $ 100 deposited at the end of 1st month earns interest for 4 months till the end of the 5th month, the $ 100 deposited at the end of the 2nd month earns interest for 3 months and so on till the last $100 deposited earns interest for '0' month.
