Find the amount of simple interest earned for depositing the given principle in an account if $2200 is invested at 5.5 % for 6 months

  $60.50

Step-by-step explanation:

Put the given numbers into the formula and do the arithmetic. 6 months is 1/2 year.

  i = Prt . . . . i is interest earned, P is principal amount, r is annual rate, t is number of years

  i = $2200×0.055×0.5 = $60.50

The amount of simple interest earned in 6 months is $60.50.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

i think that you should ask google for the answer to that problem because if we don't know it google does
