Answer:
C
Step-by-step explanation:
<em>You will cover halfway up each wall. Since the total height of the wall is 8 feet, you will cover half of that, which is 4 feet. </em>
Length is 12 feet and full length will be covered.
So area covered in 1 wall is sq. ft.
There are 4 walls, so total area to be covered is sq. ft.
Each panel board is 4 feet by 8 feet, so 1 panel board's area is sq. ft.
So number of panel boards required to cover 192 sq. ft. with 32 sq. ft. boards is
So we need 6 panels. Answer choice C is right.

A vertical line has no slope so the equation of the line is simply x = constant.
For this question we have:
x = 2
as the equation of the line.
Answer: x = 2
Please find the question attached below.
The equation that models the decrease in water (in gallons) of the fish tank over time (in hours) is y = - 20x + 180.
We know that a linear equation with one variable is one that contains just one variable.
Here we have to find the appropriate equation that models the given chart.
For option A. :
y = - 40x + 140
At x = 2, y = - 40*2 + 140 = - 80 + 140 = 60 =/ 140
So this option is incorrect.
For option B.:
y = - 40x + 180
At x = 2, y = - 40*2 + 180 = - 80 + 180 = 100 =/ 140
So this option is incorrect.
For option C.:
y = - 20x + 140
At x = 2, y = - 20*2 + 140 = - 40 + 140 = 100 =/ 140
So this option is incorrect.
For option D.:
y = - 20x + 180
At x = 2, y = - 20*2 + 180 = - 40 + 180 = 140
So this option is correct.
Therefore, the equation that models the decrease in water (in gallons) of the fish tank over time (in hours) is y = - 20x + 180. So, the last option is correct.
