Question

Write an integer to represent this situation: Draining 15 gallons of water from a fish tank

Answer 1

Answer:

The integer that representes the draining of 15 gallons of water from a fish tank is $\Delta V = V_{f} - V_{o} = -15\,gal$

Step-by-step explanation:

The gallon is a capacity (volume) units. The draining means that a part of the tank capacity occupied by water is removed. Then, the change in tank capacity is equal to a negative integer. That is:

$\Delta V = V_{f} - V_{o} = -15\,gal$

Where:

$V_{o}$, $V_{f}$ - Initial and final capacities in the fish tank, measured in gallons.

Hence, the integer that representes the draining of 15 gallons of water from a fish tank is $\Delta V = V_{f} - V_{o} = -15\,gal$
