A skyscraper has a mass of 2.2×10^5 tons. Another skyscraper in the same town has a mass of 3.7×10^5 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 add their masses together.
(2.2x10^5 tons) + (3.7x10^5 tons) = 5.9x10^5 tons
Therefore, the combined mass of the two skyscrapers is 5.9x10^5 tons.
To find the combined mass of the two skyscrapers, you'll need to add their masses together.
Given that the mass of the first skyscraper is 2.2×10^5 tons and the mass of the second skyscraper is 3.7×10^5 tons, you can add these values as follows:
2.2×10^5 tons + 3.7×10^5 tons = 5.9×10^5 tons
Therefore, the combined mass of the two skyscrapers is 5.9×10^5 tons (expressed in scientific notation to 1 decimal place).
To calculate the combined mass of the two skyscrapers, we can simply add their individual masses together.
The first skyscraper has a mass of 2.2×10^5 tons, and the second skyscraper has a mass of 3.7×10^5 tons.
To add these numbers in scientific notation, we first need to ensure that the exponents (the power of 10) are the same. In this case, both exponents are already 5.
2.2×10^5 + 3.7×10^5 = (2.2 + 3.7) × 10^5
Next, we add the coefficients (the numbers in front of the power of 10).
2.2 + 3.7 = 5.9
So, the combined mass of the two skyscrapers is 5.9×10^5 tons.
Expressing the answer to 1 decimal place, we would write it as 5.9×10^5 tons.
