A skyscraper has a mass of 2.2 x 10^5 tons. Another skyscraper in the same town has a mass of 3.7 x 10^5 tons. What is the combined mass, in tons, of the two skyscrapers? Use scientific notation to express your answer to 1 decimal place.
To find the combined mass of the two skyscrapers, we add the masses together: 2.2 x 10^5 + 3.7 x 10^5 = 6.9 x 10^5
Therefore, the combined mass of the two skyscrapers is 6.9 x 10^5 tons.
To find the combined mass of the two skyscrapers, you simply need to add their individual masses together.
First, convert both masses to scientific notation:
Mass of the first skyscraper: 2.2 x 10^5 tons
Mass of the second skyscraper: 3.7 x 10^5 tons
Now, add the two masses together:
(2.2 x 10^5) + (3.7 x 10^5) = 5.9 x 10^5
Therefore, the combined mass of the two skyscrapers is 5.9 x 10^5 tons.
To find the combined mass of the two skyscrapers, we need to add their masses together.
The mass of the first skyscraper is 2.2 x 10^5 tons.
The mass of the second skyscraper is 3.7 x 10^5 tons.
To add these two numbers, we can first convert both masses to ordinary decimal notation:
2.2 x 10^5 tons = 220,000 tons
3.7 x 10^5 tons = 370,000 tons
Now, we can add the two masses together:
220,000 tons + 370,000 tons = 590,000 tons
Finally, we express the result in scientific notation to 1 decimal place:
5.9 x 10^5 tons
So, the combined mass of the two skyscrapers is 5.9 x 10^5 tons.
