a skyscraper has a mass of 2.2 x 10^5 tons another skyscraper in the same town has a mass of 3.7 x 10^5 tons what is the combined mass in tons of the two skyscrapers use scientific notation to express your answer to the 1 decimal place
To find the combined mass of the two skyscrapers, we simply add their masses together.
Combined mass = (2.2 x 10^5 tons) + (3.7 x 10^5 tons)
= 5.9 x 10^5 tons
So, 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 together.
Given:
Skyscraper 1 mass = 2.2 x 10^5 tons
Skyscraper 2 mass = 3.7 x 10^5 tons
To add these masses, we can simply add the numbers in front of the powers of 10 (the coefficients) and keep the same power of 10.
2.2 x 10^5 + 3.7 x 10^5 = (2.2 + 3.7) x 10^5 = 5.9 x 10^5
Therefore, the combined mass of the two skyscrapers is 5.9 x 10^5 tons (expressed to 1 decimal place in scientific notation).
To find the combined mass of the two skyscrapers, you simply need to add their individual masses together.
The first skyscraper has a mass of 2.2 x 10^5 tons.
The second skyscraper has a mass of 3.7 x 10^5 tons.
To add these two masses, first convert them to scientific notation with the same exponent:
2.2 x 10^5 tons = 22.0 x 10^4 tons
3.7 x 10^5 tons = 37.0 x 10^4 tons
Now, add the converted masses:
22.0 x 10^4 tons + 37.0 x 10^4 tons = 59.0 x 10^4 tons
To express the answer to 1 decimal place in scientific notation, we need to divide the number by 10 to adjust the exponent.
59.0 x 10^4 tons = 5.9 x 10^5 tons
Therefore, the combined mass of the two skyscrapers is 5.9 x 10^5 tons.
