The combined volume of all the things and aquarium is 1.25×10 to the six power gallons the aquarium plants to install a new dolphin take with a volume of 250,000 gallons what was the total volume of all the tanks at the aquarium after the new dolphin tank is installed

1,500,000 gallons

Step-by-step explanation:

In this question, we are to calculate the total volume of the aquarium after installing a new dolphin tank.

Mathematically, to calculate this, we simply need to add the the volume of the new dolphin tank to the volume of the things in the aquarium before bringing the dolphin tank.

The volume of all the things in the aquarium before installing the dolphin tank is 1.25 * 10^6 = 1,250,000 gallons

now let’s add the volume of the dolphin tank which is 250,000 gallons

that would be 1,250,000 + 250,000 = 1,500,000 gallons or 1.5 * 10^6 gallons

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
