It take 8.205 minutes to fill a queen sized mattress.
<h3>What is volume?</h3>
'Volume' is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.
Given dimensions:
Twin sized air mattress (39 by 8.75 by 75 inches).
Queen sized mattress (60 by 8.75 by 80 inches)
Now, Volume of twin sized mattress
=39* 8.75* 75
= 25593.35 cubic inch
Volume of queen sized mattress,
=60* 8.75* 80
= 42000 cubic inch
as, To fill 25593.35 cubic inch it takes 5 minutes
so, to fill 1 cubic inch = 5/25593.35
and, So to fill 42000 cubic inch it will take = 42000* 5/25593.35
=8.205 minutes

Answer: y<2
Step-by-step explanation:
Since we can say a functions could be added to the system without changing the solution set if after including it to the system the feasible region of entire system is not affected.
Here, the solution to the system of inequalities is,
y≤ 0.5x+2
y>3x-3
Since after ploting these two enequslties in the graph we get our feasible region.
When we include y > 2 in the system there is no solution of the system.
Therefore it affects the system.
Now when we include y < 2 in the system the solution or feasible region remain same.
Therefore it does not affect the system.
When we include y > 3 in the system there is no solution of the system.
Therefore it affects the system.
When we include line y=3 in the system then the system has no solution.
Therefore, it affects the system.
Thus, second Option is correct.
For the first one is D
The second one is A
The third one should be B, it makes the most sence
