Which of these people repaid his loan at a variable interest rate? andre, who made monthly payments of $57 for one year gary, who paid $37 each month for the first six months and $67 each month for the next six months dean, who repaid the full amount of the loan in one installment

Answer :Gary, who paid $37 each month for the first six months and $67 each month for the next six months

Andre, who made monthly payments of $57 for one year . Single amount is paid every month for one year. So same interest rate for the whole year.

Gary, who paid $37 each month for the first six months and $67 each month for the next six months. Different loan amount is paid for the whole year. Variable interest rates are used because the amount varies for first six months and next six months.

Dean, who repaid the full amount of the loan in one installment. No interest rates because full payment is done in one installment.

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
