For the first movie he has 6 choices, then for the second since he has chosen the first there are only 5 left, then for the third there are only 4 choices left and so on.

Therefore the answer is 6!=6*5*4*3*2=720 orderings

So,

We can see that this is a permutation.

The total number of permutations will be the number with an exclamation mark attached to it.

6! = total number of possible permutations
6! = 720

There are 720 possible permutations.

Six pipes are laid end to form a row.each pipe is 9 1/3 inches long.how long is the row of pipes in feet?
laiz [17]

six pipes are laid end to end to form a row. Each pipe is 9 1/3 inches long. how long is the row of pipes, in feet?

Answer:

4.67 feet or 4 feet 8 inches or 4\frac{2}{3}feet

Step-by-step explanation:

Let x be the length of the row pipes.

Given:

Number of pipes = 6

Each pipe has length 9\frac{1}{3} inches. and six pipes are laid end to end to form a row.

The total length of the row is equal to length of the 6 pipes.

So, total length of row = Number of pipes \times Length of the pipe

x=\frac{28}{3}\times 6

x=28\times 2

x=56 inches

convert inch into feet.

x=\frac{56}{12}

x=4.67 feet

Therefore, The length of the row is 4.67 feet or 4 feet 8 inches or 4\frac{2}{3}feet .
