Using the volume of the spherical balloon, it is found that it will take 24 hours for the balloon to become completely empty.
<h3>What is the volume of a sphere?</h3>
The volume of a sphere of radius r is given by:
Aspherical balloon has a radius of 6 feet, hence the volume is:
It has already lost 20% of it's air, and air is leaking out of the balloon at a rate of 30 cubic feet per minute, hence the volume after t minutes is given by:
It will be completely empty when:
Rounding, it will take 24 hours for the balloon to become completely empty.

Answer:
Sometimes they represents the same value
Step-by-step explanation:
the expression x-3 and y-3 represent the same value.
yes sometimes the expression x-3 and y-3 represent the same value.
the expression x-3 and expression y-3 represents the same value only when x=y (that is only when x and y values are same)
For example
when x=5 and y=5
then expression x-3 becomes 5-3= 2
the expression y-3 becomes 5-3=2
so both the expression give same value when x=y
Sometimes they represents the same value
