688,747,536 ways in which the people can take the seats.

</h3><h3>
How many ways are there for everyone to do this so that at the end of the move, each seat is taken by exactly one person?</h3>
There is a 2 by 10 rectangular greed of seats with people. so there are 2 rows of 10 seats.
When the whistle blows, each person needs to change to an orthogonally adjacent seat.
(This means that the person can go to the seat in front, or the seats in the sides).
This means that, unless for the 4 ends that will have only two options, all the other people (the remaining 16) have 3 options to choose where to sit.
Now, if we take the options that each seat has, and we take the product, we will get:
P = (2)^4*(3)^16 = 688,747,536 ways in which the people can take the seats.

Answer:
Step-by-step explanation:
Given:
The figures cylinder, cube, cone, and pyramid.
To find:
The formula of volume for the given figures.
Solution:
Volume of a cylinder is:
Where r is the radius and h is the height.
Volume of a cube is:
Where a is side length of cube.
It is also written as:
Where l is length, w is width, h is height and 
.
Volume of a cone is:
Where r is the radius and h is the height.
Volume of a pyramid is:
Where B is the base area and h is the height.
Therefore the table of formulae is shown below:

Answer:
1/2 of a pound.
Step-by-step explanation:
Step 1: You take 2 and 1/2 and convert it to an improper fraction.
2 1/2 = 5/2
Step 2: Divide 5/2 by 5.
5/2 / 5 = 1/2
Your answer is 1/2
5 - c - d
5 - 8 - (-13)
5 - 8 + 13
-13 + 13
0
The value of the expression when c = 8, and d = -13 is c. 0
