A skyscraper has a mass of 2.2x10^(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. (1 point)

Answer 1

To find the combined mass of the two skyscrapers, you need to add their masses together.

The first skyscraper has a mass of 2.2 x 10^5 tons.
The second skyscraper has a mass of 3.7 x 10^5 tons.

Adding these two masses together, you get:

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.
