Answer: 720</h3>
============================================================
Explanation:
The number 8 from "8 year old boy" can be completely ignored. In my opinion, this is an (un)intentional distraction on your teacher's part.
There are 6 toys to arrange. The order is important.
- For the first slot, there are 6 choices.
- Then the second slot has 5 choices (we cannot have a toy occupy more than one slot at a time).
- The third slot has 4 choices, and so on.
We have this countdown: 6,5,4,3,2,1
Those values multiply out to 6*5*4*3*2*1 = 720
There are 720 ways to arrange the 6 different toys. Order matters.
---------------------
An alternative approach is to use the nPr permutation formula with n = 6 and r = 6. We use a permutation because order matters.
The nPr formula is

where the exclamation marks indicate factorial. For example, 6! = 6*5*4*3*2*1 = 720.
Answer:
x(y² - 4) = 1.512
Step-by-step explanation:
We need to evaluate the following expression for x = 0.2 and y = 3.4 :
x(y² - 4)
Put the values of x and y.
x(y² - 4) = (0.2)((3.4)² - 4)
= (0.2)((3.4)² - 4)
= 0.2×7.56
= 1.512
So, the value of the above expression is 1.512
Answer: I think its $176.40
Step-by-step explanation:
The area would be 21
Feet would be = 50.4 (21 x 2.4)
Then it would cost $176.40 (50.4 x $3.50)
I might be wrong, I'm not entirely sure.
