An account earns simple interest.<br><br> $5200 at 7.36% for 54 months

vovikov84 [41]

A = P(1 +rt) where A is the total amount(principal and interest), r is the rate, and t is the time invested.

A = 5200[1 + .0736(4.5)]
A = 6922.24

note we had to change the rate to a decimal by dividing by 100
Also 54 months is equal to 4.5 years...you enter time in years.

The area of a rectangle is 30 square root 3750 square inches, and the length is 3 square root 250 inches what is the width of th

Ann [662]

Answer:

$width=10\sqrt{15}\ in$

Step-by-step explanation:

-A rectangle's area is given by:

$A=lw\\\\l=length\\w=width$

Given A= $30\sqrt{3750}$ and $l=3\sqrt{250}$ , we substitute in the formula to solve for the width as follows:

$A=lw\\\\30\sqrt{3750}=3\sqrt{250}\times w\\\\w=\frac{30\sqrt{3750}}{3\sqrt{250}}\\\\w=10\frac{\sqrt{3750}}{\sqrt{250}}\\\\=10\times \sqrt{\frac{3750}{250}}\\\\=10\sqrt{15}\ in$

Hence , the rectangle's width is $10\sqrt{15}\ in$
