Answer:
The side length of of the base of the tank is 15 inches.
Step-by-step explanation:
We are given the following in the question:
Cost of the tank and filter system = $280
Perimeter of tank base = 60 inches
The perimeter of tank is in the shape of square.
We have to find the side length of the base of the tank.
Perimeter of tank base = Perimeter of square =
Thus, the side length of of the base of the tank is 15 inches.
Given :
Median salary of engineer , E = $55,000 .
Median salary of computer engineer , C = $52,000 .
To Find :
The total cost for a business to employ two engineers and three programmers for 1 year .
Solution :
Now , cost of paying two engineers .
Also , cost of paying three programmers .
Therefore , total cost for 1 year is .
Hence , this is the required solution .
the complete question in the attached figure
step 1
Find the distance of the center of the wall from the left end of the wall
distance=(1/2)*24--------> 12 ft
so
If x is the distance from a painting edge to its corresponding end of the wall, then
|x-12| is the distance from the painting edge to the center of the wall
and
If the painting is centered, then 2|x-12| represents the width of the painting
Since the painting is 10 ft wide,
we have 2|x-12|=10
therefore
the answer is the option B
2|x-12|=10
