A skyscraper has a mass of 2.2 x 10^5 tons. Another skyscraper in the same town has a mass 3.7 x 10^5 tons. What is the combined mass, in tons, of two skyscrapers? use scientific notation to express your answer to 1 decimal place
To find the combined mass of the two skyscrapers, we can simply add their masses together.
2.2 x 10^5 tons + 3.7 x 10^5 tons = 5.9 x 10^5 tons
Therefore, the combined mass of the two skyscrapers is 5.9 x 10^5 tons.
To find the combined mass of the two skyscrapers, we need to add their masses.
First, let's write the masses in scientific notation:
Skyscraper 1 mass: 2.2 x 10^5 tons
Skyscraper 2 mass: 3.7 x 10^5 tons
Now, let's add the masses:
2.2 x 10^5 + 3.7 x 10^5
To add these numbers in scientific notation, we need to have the same exponent (power of 10). Let's rewrite the numbers so that they have the same exponent:
2.2 x 10^5 = 0.22 x 10^6 (dividing by 10)
3.7 x 10^5 = 0.37 x 10^6 (dividing by 10)
Now, let's add the masses:
0.22 x 10^6 + 0.37 x 10^6 = 0.59 x 10^6 (adding the decimal part)
Combining these results, the combined mass of the two skyscrapers is 0.59 x 10^6 tons.
To express the answer to 1 decimal place, we can round the number:
0.59 x 10^6 tons = 5.9 x 10^5 tons
Therefore, the combined mass, in tons, of the two skyscrapers is 5.9 x 10^5 tons (to 1 decimal place).
To calculate the combined mass of the two skyscrapers, we simply need to add their individual masses 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 these two numbers in scientific notation, we need to make sure the powers of 10 are the same. In this case, both masses are already in the same scientific notation.
Now, we can proceed to add the masses:
(2.2 x 10^5) + (3.7 x 10^5) = 5.9 x 10^5
Thus, the combined mass of the two skyscrapers is 5.9 x 10^5 tons, expressed in scientific notation to 1 decimal place.
