The combined volume of all the tanks at an aquarium is 1.25*10^6 gallons. The aquarium ... At an aquarium is 1.25*10^6 gallons. The aquarium plans to install a new dolphin tank with a volume of 250000 gallons. What will be the total volume of all the tanks at the aquarium after the new dolphin tank is install.

1.50 × 10^6 gallons

Step-by-step explanation:

Given that ;

Combined volume of all tanks = 1.25×10^6 gallons

Volume of new tank to be installed = 250000 gallons

Total volume of all tanks after installing the new tank:

Initial volume of combined tanks + volume of new tank

1.25×10^6 + 250000

250000 in standard notation

250000 = 0.25×10^6

Hence,

1.25×10^6 + 0.25×10^6

= (1.25 + 0.25) × 10^6

= 1.50 × 10^6 gallons

1,918
