Step-by-step explanation:

The compound interest equation is ...

  B(t) = P(1 + r/n)^(nt)

where r is the annual interest rate and n is the number of times per year it is compounded.

Comparing this general formula to the given equation, we see that ...

P = 124r = .05 = 5%n = 4 . . . . (compounded quarterly, 4 times per year)t = (still a variable representing the number of years)

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
