A skyscraper has a mass of 2.2x10^5 tons. Another skyscraper in the same town has a mass of 3.7x10^5 tons. What is the combined mass, in tons, of the two skyscrapers? Use scientific notation to express your answer to 1 decimal place.
The combined mass of the two skyscrapers is (2.2x10^5 + 3.7x10^5) tons = (5.9x10^5) tons.
To find the combined mass of the two skyscrapers, we need to add their masses together.
Given:
Mass of skyscraper 1 = 2.2x10^5 tons
Mass of skyscraper 2 = 3.7x10^5 tons
To add these two masses, we can simply add the numbers in front of the powers of 10 and keep the power of 10 the same.
2.2x10^5 + 3.7x10^5 = (2.2 + 3.7) x 10^5
Adding the numbers in front, we get:
5.9 x 10^5
Therefore, the combined mass of the two skyscrapers is 5.9x10^5 tons.
To find the combined mass of the two skyscrapers, you need to add their individual masses. Given that the first skyscraper has a mass of 2.2x10^5 tons and the second skyscraper has a mass of 3.7x10^5 tons, you can add these two values together.
First, convert both masses to standard notation:
2.2x10^5 tons = 220,000 tons
3.7x10^5 tons = 370,000 tons
Now, add the two masses together:
220,000 tons + 370,000 tons = 590,000 tons
Therefore, the combined mass of the two skyscrapers is 5.9x10^5 tons (or 590,000 tons in standard notation).
