A skyscraper has a mass of 2.2 times 10,5 tons another skyscraper in the same town has a mass of 3.7 times 10,5 tons. What is the combined mass, in tons, of the two of the two skyscraper?

Answer 1

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

Mass of first skyscraper = 2.2 × 10^5 tons
Mass of second skyscraper = 3.7 × 10^5 tons

Combined mass = Mass of first skyscraper + Mass of second skyscraper
= 2.2 × 10^5 tons + 3.7 × 10^5 tons

To add these two masses, we need to have the same exponent for the 10 parts of the scientific notation. Let's convert both masses to the same exponent (10^5) by adjusting their coefficients.

= (2.2 + 3.7) × 10^5 tons

Now, we can compute the sum.

= 6.9 × 10^5 tons

Therefore, the combined mass of the two skyscrapers is 6.9 × 10^5 tons.
