If you pay $5,500 for a simple interest note that will be worth $6,000 in 21 months,
what annual simple interest rate will you earn?

  5.19%

Step-by-step explanation:

The amount of an account (A) earning simple interest rate r for time t on principal P is ...

  A = P(1 +rt)

Filling in the given values and solving for r gives ...

  6000 = 5500(1 +r(21/12))

  12/11 = 1 + r(7/4) . . . . . . . . . . divide by 5500, simplify fractions

  1/11 = r(7/4) . . . . . . . . subtract 1

  4/77 = r . . . . . . . . . . . multiply by 4/7

  r ≈ 0.051948 ≈ 5.19%

You will be earning about 5.19% annual simple interest.

The annual simple interest rate is 5.19%

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the simple interest note.

P represents the principal or amount paid for the simple interest note.

R represents interest rate

T represents the duration in years.

From the information given,

P = 5500

T = 21 months = 21/12 = 1.75 years

I = 6000 - 5500 = $500

500 = (5500 × R × 1.75)/100

500 = 9625R/100 = 96.25R

R = 500/96.25

R = 5.19%

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
