The rule being used here is
which is often used to simplify square roots.
Answer:
a
Step-by-step explanation:
6ft = 72 inches
72 + 10 = 82 inches
First we'll consider the floor size.
In a 10 by 12 room the longest pipe that will fit lying on the floor equals the hypotenuse of a 10 by 12 triangle:
hypotenuse² = 10² + 12²
hypotenuse² = 100 + 144
hypotenuse² = 244
hypotenuse =
<span>
<span>
<span>
15.62 feet
Now we have to consider the third dimension (height = 8 feet).
The two sides would be 15.62 and 8
</span></span></span>hypotenuse² =
15.62² + 8²
hypotenuse² =
244 + 64 = 308
hypotenuse = 17.55
So, the longest pipe that would fit in that room would be 17.55 feet long.
Answer:

Step-by-step explanation:
we have

where
Q -----> is the daily output
A -----> is the number of people
For Q=621
Find the value of A
substitute and solve for A

Subtract 600 both sides


squared both sides


Subtract 41 both sides

Rewrite
