The combined volume of all the tanks at an aquarium is 1.25*10^6 gallons. the aquarium plans to install a new dolphin tank with a volume of 25 gallons. what will be the total volume of all the tanks at the aquarium after the new dolphin tank is install

1500000 gallons.

Step-by-step explanation:

To solve this problem we can use the scientific notation.

Currently, all tanks at the aquarium have a combined volume of 1.25 x 10⁶ gallons.

The new tank has a volume of 250000 gallons, this number can be written as .25 x 10⁶

Now we're going to sum up the two quantities to find out the volume (both numbers have the same potency of 10):

(1.25 x 10⁶) + (.25 x 10⁶)  = 1.50 x 10⁶.

Therefore, the volume of all the tanks will be 1.5 x 10⁶ gallons, which can also be written as 1500000 gallons.
