7%

Step-by-step explanation:

The problem has a misspelling. The word should be "principal" not "principle."

Formula for simple interest:

I = Prt

where I = amount of interest

P = principal

r = annual rate of interest

t = time in years

I = Prt

509.60 = 910.00 * r * 8

910 * r * 8 = 509.6

7280r = 509.6

r = 0.07

The interest rate is 0.07 as a decimal.

To write it as a percent, we multiply the decimal by 100.

0.07 = 0.07 * 100% = 7%

is there answer choices?

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
