DaniilM [7]

1. The combined volume of all the tanks at the aquarium is written in Scientific notation. Keeping this on mind, you can write it as following:

(1.25)(10^{6})=1,250,000gallons

2. Now, you must sum the combined volume of all the tanks and the volume of  the new tank to calculate the total volume of all of them:Vt=1,250,000gallons+250,000gallons\\Vt= 1,500,000gallons

3. Now, you can write the result in Scientific notation, as following:

Vt=(1.5)(10^{6}) gallons

The answer is: (1.5)(10^{6}) gallons
