there are 12 actors auditioning for 5 different roles in a new play. how many different cast are possible
aleksandr82 [10.1K]

Answer:

95,040 different cast are possible

Step-by-step explanation:

In this case the order in which the actors are selected for the 5 different roles is important. Therefore we use the permutations formula.

nPr =\frac{n!}{(n-r)!}

Where n is the number of items you can choose and choose r from them.

In this case n = 12 and r = 5

12P5 =\frac{12!}{(12-5)!}

12P5 =\frac{12!}{7!}

12P5 =95040

A tree in John's backyard has been growing for 4 1/2 years. The tree is 4/5 meters tall. What is the unit rate in meters per yea
STatiana [176]

Answer:

<u>5 127/200 meters</u>

Step-by-step explanation:

4 1/2 = 4 5/10 | 4/5 = 8/10

--------------------------------------

4 5/10 = 4.5 | 8/10 = 0.8

--------------------------------------

4.8 divided by 0.8 = 5.625

--------------------------------------

5.635 = 5 635/1000

635/1000 divided by 5 = 127/200

--------------------------------------

5 + 127/200 = <u>5 127/200</u>

Solving systems of equations using substitution. y=2x+8. y=5-x
kherson [118]

Answer:

(x, y) = (-1, 6)

Step-by-step explanation:

y = 2x + 8

y = 5 - x

Substituting the second equation into the first equation, we get:

5 - x = 2x + 8

5 = 3x + 8

-3 = 3x

x = -1.

So, y = 5 - (-1).

Simplifying, we get:

y = 6.
