Members from 6 different school organizations decorated floats for the homecoming parade. How many different ways can first, sec
Alex
<h3>Answer:  120 different ways</h3>

=======================================================

Explanation:

There are...

  • 6 ways to select the first place winner
  • 5 ways to pick the second place winner
  • 4 ways to pick the third place winner

We start with 6, and count down by 1 each time we fill up a slot. We stop once the third slot is filled or accounted for. The countdown is to ensure that we don't pick the same person twice. From here, multiply those values: 6*5*4 = 30*4 = 120

Interestingly, this is equal to 5! = 5*4*3*2*1 = 120 because the 3*2 becomes 6 and that *1 at the end doesn't affect things. Though usually results of permutation problems don't always end up like this. The order matters because a result like ABC is different from BAC, where A,B,C,D,E,F are the six school organizations.

As a slightly longer way to do the problem, you can use the nPr formula which is _nP_r = \frac{n!}{(n-r)!} where n = 6 and r = 3 in this case. The exclamation marks indicate factorial. If you go this route, you should find that one of the steps will involve 6*5*4.

Choose the linear equations.
andrew-mc [135]

Answer:

y = \frac{3}{3}x - 5

y = 2x + 5

Step-by-step explanation:

In linear equations, both variables x and y must have the exponent of 1 (i.e. they cannot have a small number at the top-right). And they cannot be in the exponents (i.e. cannot be the small number at the top-right).

Find the volume of oxygen in a room with the dimensions of 144.78 cm x 198.12 cm x 144.78
blondinia [14]

Answer:

  4,152,842.53301 cm³ ≈ 4.1528 m³

Step-by-step explanation:

The volume of a rectilinear room of those dimensions will be the product of those dimensions:

  (144.78 cm)(198.12 cm)(144.78 cm) = 4,152,842.53301 cm³

A more appropriate unit for such a volume is cubic meters. There are a million cubic centimeters in a cubic meter, so the volume (to 5 significant digits) is ...

  4.1528 m³

_____

We assume that any oxygen is uniformly distributed in the space, so the volume of oxygen will be the same as the volume of the room.

_____

<em>Additional comment</em>

These dimensions correspond to those of a room that is 57 inches square and 78 inches high.
