If $1600 earned simple interest of $56.24 in 2 months, what was the simple interest rate? The simple interest rate is % (Do not
Fiesta28 [93]

Answer:

\$21.1

Step-by-step explanation:

We know that for principal amount P , time period T and rate of interest R\% , simple interest is given by S.I. = \frac{P\times R\times T}{100} .

Here ,

P=\$1600\\T=2\,\,months=\frac{2}{12}\,\,years=\frac{1}{6}\,\,years\\S.I=\$56.24

To find :  simple interest rate i.e., R\%

On putting values of P\,,\,T\,,\,S.I in formula , we get S.I. = \frac{P\times R\times T}{100}

56.24 = \frac{1600\times R\times 1}{600}\\R=\frac{56.24\times 600 }{1600}=\frac{703\times 3}{100}=\$21.09

Now we need to round off the answer to the nearest tenth .

So, simple interest rate is % = \$21.09 = \$21.1

The length of a rectangular garden is 17 feet longer than its width. If the area of the garden is 234 square feet, what are the
kifflom [539]

Answer:

The garden is 9 feet wide and 26 feet long.

Step-by-step explanation:

L = W+17

area = LW = 234

(W+17)W = 234

W²+17W-234 = 0

Quadratic formula

W = [-17 ± √(17² – 4·1(-234))] / [2·1]

 = [-17 ± √1225] / 2

 = [-17 ± 35] /2

 = -26, 9

-26 is an extraneous solution

W = 9

L = W+17 = 26

The garden is 9 feet wide and 26 feet long.
