If the simple interest on $8000 for 3 years is $540, what is the rate of interest per annum?​

2.25%

Step-by-step explanation:

I = Prt

Given:

I = 540

P = 8000

t = 3

Solve for r:

I = Prt

r = I/(Pt)

r = 540/(8000 * 3)

r = 540/24000

r = 0.0225

Rate in percentage form:

0.0225 * 100 = 2.25%

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

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
