Answer:
4 pieces of chair rail are needed
Step-by-step explanation:
<u>Step 1: Calculate the perimeter of the room</u>
Perimeter of rectangle = 2L + 2B
Length = 18
Breadth = 14
Perimeter of room = 2(18) + 2(14)
Perimeter of room = 64 feet
<u>Step 2: Calculate the pieces of chair rail needed</u>
<em>Perimeter of room = 64 feet</em>
<em>Length of each chair rail = 16 feet</em>
<em>Total chair rails needed = Perimeter of room/length of each chair rail</em>
<em>Total chair rails needed = 64/16</em>
Total chair rails needed = 4
Therefore, Mr. Herzog needs 4 pieces of chair rails.

Determine the concentration at the end of 4 hours
First, calculate the amount of liquid that has been replaced at the end of the 4 hours.
This implies that, over the 4 hours; The tank has 160000 liters of liquid out of 440000 liters were replaced
Calculate the ratio of the liquid replaced.
Next, calculate the amount of solid left.
Lastly, the concentration is calculated as:
Convert L to cubic meters
2 eggs are used for each batch of nut bars
