A skyscraper has a mass of 2.2 × 10 tons. Another skyscraper in the same town has a made of 3.7 × 10 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, we add the masses of the two skyscrapers together.
2.2 × 10 tons + 3.7 × 10 tons = 5.9 × 10 tons
Therefore, the combined mass of the two skyscrapers is 5.9 × 10 tons.
To find the combined mass of the two skyscrapers, we need to add their masses together.
The first skyscraper has a mass of 2.2 × 10 tons.
The second skyscraper has a mass of 3.7 × 10 tons.
Adding these two masses together, we get:
2.2 × 10 + 3.7 × 10 = 5.9 × 10 tons
Therefore, the combined mass of the two skyscrapers is 5.9 × 10 tons.
To find the combined mass of the two skyscrapers, you need to add their individual masses.
The first skyscraper has a mass of 2.2 × 10 tons, which can be written as 2.2 × 10^1 tons in scientific notation.
The second skyscraper has a mass of 3.7 × 10 tons, which can be written as 3.7 × 10^1 tons.
To add these two masses, add the coefficients (2.2 + 3.7 = 5.9) and keep the exponent the same (10^1).
Therefore, the combined mass of the two skyscrapers is 5.9 × 10^1 tons.
In scientific notation, this can be written as 5.9 × 10 tons or 59.0 tons.
