A skyscraper has a mass of 2.2×10^5 tons. Another skyscraper in the same town has a mass of 3.7×10^5 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, we need to add their masses together.

2.2×10^5 tons + 3.7×10^5 tons

= (2.2 + 3.7) × 10^5 tons

= 5.9 × 10^5 tons

So the combined mass of the two skyscrapers is 5.9 × 10^5 tons.
