A skyscraper has a mass of 2.2 x 10 tonsAnother skyscraper in the same town has a mass of 3.7 x 105 tonsWhat 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 add their masses together.

2.2 x 10 tons + 3.7 x 10^5 tons = 2.2 x 10 + 3.7 x 10^5 tons

To add these numbers in scientific notation, we need to bring them to the same power of 10.

2.2 x 10 + 3.7 x 10^5 tons = 2.2 x 10^1 + 3.7 x 10^5 tons

Now we can add the numbers:

2.2 x 10^1 + 3.7 x 10^5 = 22 + 370000

= 370022

Therefore, the combined mass of the two skyscrapers is 3.7 x 10^5 tons.
