The 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.
To find the combined mass of the two skyscrapers, we need to add their individual masses.
The mass of the first skyscraper is 2.2x10^5 tons.
The mass of the second skyscraper is 3.7x10^5 tons.
To add these masses, we need to have the same power of 10. Let's convert the mass of the second skyscraper to the same power of 10 as the first skyscraper.
3.7x10^5 tons is the same as 37x10^4 tons.
Now, let's add the two masses: 2.2x10^5 tons + 37x10^4 tons = (2.2 + 37)x10^4 tons = 39.2x10^4 tons.
To express the answer in scientific notation to 1 decimal place, we need to divide 39.2x10^4 tons by 10^4 to obtain a number between 1 and 10:
39.2x10^4 tons / 10^4 = 3.92x10^(4+10-4) tons = 3.92x10^10 tons.
Therefore, the combined mass of the two skyscrapers is 3.9x10^10 tons.
To find the combined mass of the two skyscrapers, we simply need to add the masses of the two skyscrapers together.
Given:
Mass of the first skyscraper = 2.2 x 10^5 tons
Mass of the second skyscraper = 3.7 x 10^5 tons
To add the masses, we add the numbers without the powers of 10:
2.2 + 3.7 = 6.9
To determine the power of 10 in scientific notation, we add the powers of 10:
10^5 + 10^5 = 10^5
Therefore, the combined mass of the two skyscrapers is 6.9 x 10^5 tons.
To find the combined mass of the two skyscrapers, you need to add their masses together.
The first skyscraper has a mass of 2.2x10^5 tons, and the second skyscraper has a mass of 3.7x10^5 tons.
To add these two numbers in scientific notation, you need to make sure the exponents (the powers of 10) are the same. In this case, both numbers already have the same exponent of 10^5.
Now, you can add the coefficients (the numbers before the "x10^5" part) together:
2.2 + 3.7 = 5.9
The combined mass of the two skyscrapers is 5.9x10^5 tons.
