Use the formula   i = p*r*t:
                                                               $456
$456 = $1600*r*6.  Solving for r, r = ----------------- = 0.0475, or 4 3/4%
                                                           ($1600)(6)

ICE Princess25 [194]

Answer:

First piece = 6 inches

Second piece = 12 inches

Third piece = 18 inches

Step-by-step explanation:

Length of the first piece = x

Length of the second piece = 2x

Length of the third piece = 3x

Total length is 36 inches:

x + 2x + 3x = 36

6x = 36

x = 6

Therefore, the lengths are:

First piece = 6 inches

Second piece = 12 inches

Third piece = 18 inches

Can someone please solve this please?!
sasho [114]

Answer:

56

Step-by-step explanation:

This problem can be solved b using a combination. We're using a combination for this because the order in which you would pick the songs doesn't matter. To solve, we would plug in the number of songs we want to download, in this case 8, into the n value of the combination. Then we would plug in the number of songs that we can pick, in this case 3, in the r value of the combination. Solve the combination and we get 56.
