f the exterior angle of a polygon is given, then the formula to find the interior angle is Interior Angle of a polygon = 180° – Exterior angle of a polygon Method 3: If we know the sum of all the interior angles of a regular polygon, we can obtain the interior angle by dividing the sum by the number of sides

Answer:

60 different ways.

Step-by-step explanation:

We have been given that you have 5 reindeer, Bloopin, Rudy, Ezekiel, Prancer, and Balthazar, and you want to have 3 fly your sleigh. You always have your reindeer fly in a single-file line. We are asked to find the number of ways in which we can arrange reindeer.

We will use permutations to solve our given problem.

The number of way to choose r objects from a set of n objects is $^nP_r=\frac{n!}{(n-r)!}$ .

Upon substituting our given values in permutations formula, we will get:

$^5P_3=\frac{5!}{(5-3)!}$

$^5P_3=\frac{5!}{2!}$

$^5P_3=\frac{5\times 4\times 3\times 2!}{2!}$

$^5P_3=5\times 4\times 3$

$^5P_3=60$

Therefore, you can arrange your reindeer in 60 different ways.

Can You show me how to do this?

Elanso [62]

22a is < since multiplying something by a fraction less than one makes it smaller.
22b is = since multiplying something by a fraction equal to one makes it stay the same.
22c is > since multiplying something by a mixed number makes it larger.
22d is < since multiplying something by a fraction less than one makes it smaller.
Hope this helps!
