<span>Krystal's rate = 1 floor in 16 min. = 1/16 floors per min.
Working together their rate = 1 floor in 5.76 min. = 1/5.76 floors per min.
We need to determine Perry's rate, so we need to equate their combined rate with the sum of the individual rates.
Let Perry's time = x
In equation form, we can write:
1/16 + 1/x = 1/5.76
Solve for x:
(x+16)/16x = 1/5.76 -> 5.76(x+16) = 16x -> 10.24x = 92.16 -> x = 9
So, Perry would take 9 mins. to do the floor alone.
I hope this helped!

Answer:
Number one the base is 24 and the Volume is 120
Number two the base is also 24 and the Volume is 240.
Step-by-step explanation:
For #1:
For the first one the area of the base is 8x3 which equals 24 so for base Number 1 its 24.
All we got to do to figure out the volume is multiply by 10 *the height* and then divide by 2 because we are finding the volume of a pyramid. 24x10 = 240/2 = 120. So the volume for Number 1 is 120.
For #2:
It has the exact same number except we are dealing with a rectangular prism which means at the end we don't have to divide by 2. For the base its 8 x 3 = 24 the same as the pyramid. For the volume- 8 x 3 = 24 x 10 = 240 which means the volume is 240. And of course don't forget the unit yards³
