Hello there!
You can use the equation:
504 ÷ 6
84
The hotel can buy 84 pillows.
Hope this helped! :D
Answer:
because the power of the polynomial (T) is 0.5 where the polynomial considered when it must have power as 1,2 or many more.
The volume of the pipe is about 282.6 cubic feet.
First, we need to find the area of each circular cross section and subtract them to find the width of the pipe. The area of a circle is pi(r^2).
pi(3^2) - pi(2^2)
28.26 - 12.56 = 15.7
The width of the pipe is 15.7. Now, multiply that by 18 to find the volume.
15.7 x 18 = 282.6
There are 680 combinations of four teachers include Mrs. Vera(only)
<h3>How to determine the number of combination?</h3>
The given parameters are
Teachers, n = 18
Selected teachers. r = 4
The selection must include Mrs. Vera.
So, the remaining parameters are:
Teachers, n = 17
Selected teachers. r = 3
The combination is then calculated as:
Ways = nCr
This gives
Ways = 17C3
Apply the combination formula
Ways = 17!/(14!3!)
Evaluate the expression
Ways = 680
Hence, there are 680 combinations of four teachers include Mrs. Vera(only)
