A skyscraper has a mass of 2.2×10^5 tons. Another skyscraper in the same town has a mass of 3.7×105 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 can simply add their masses together:

1. The mass of the first skyscraper is \( 2.2 \times 10^5 \) tons.
2. The mass of the second skyscraper is \( 3.7 \times 10^5 \) tons.

Now, adding these together:

\[ (2.2 \times 10^5) + (3.7 \times 10^5) = (2.2 + 3.7) \times 10^5 = 5.9 \times 10^5 \text{ tons} \]

Thus, the combined mass of the two skyscrapers is:

\[ \boxed{5.9 \times 10^5} \text{ tons} \]
