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.
Answer:
4 and 5
Step-by-step explanation:
Let the numbers be x and y
If their sum is 9, hence;
x + y = 9 ....1
When reversed
10y+x = 2(10x+y)
10y+x = 20x + 2y
10y - 2y = 20x - x
8y = 19x
y = 10x/8 ...2
Substitute equation 2 into 1;
From 1;
x+y = 9
x +(10x/8) = 9
18x/8 = 9
18x = 72
x = 72/18
x = 4
Since x+y =9
y = 9-x
y =9-4
y = 5
Hence the numbers are 4 and 5
