a skyscraper has a mass of 2.2*10^5tons another in the same town has a mass of 3.7*10^5tons what is the combined mass in tons of the two skyscrapers use scientific notation to express your answer to 1 decimal place
The combined mass of the two skyscrapers is (2.2*10^5 + 3.7*10^5) tons.
This can be simplified by adding the numbers without the exponents: 2.2 + 3.7 = 5.9.
The exponent remains the same: 10^5.
Therefore, the combined mass is 5.9*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 2.2 * 10^5 tons, and the second skyscraper has a mass of 3.7 * 10^5 tons.
To add these masses, align the decimal places and then add the numbers:
2.2 * 10^5
+ 3.7 * 10^5
-------------
6.9 * 10^5
Therefore, the combined mass of the two skyscrapers is 6.9 * 10^5 tons.
To calculate the combined mass of the two skyscrapers, you need to add their masses together.
Given:
Mass of the first skyscraper = 2.2 * 10^5 tons
Mass of the second skyscraper = 3.7 * 10^5 tons
To add these masses in scientific notation, you should ensure that the exponents (the powers of 10) are the same. In this case, we need to adjust the first mass to have the same exponent as the second mass, which is 10^5.
To do this, we can express 2.2 * 10^5 tons in scientific notation as 0.22 * 10^6 tons. Here, we move the decimal point one place to the right and change the exponent to 6 to maintain the same value.
Now, we can add the adjusted masses:
0.22 * 10^6 tons + 3.7 * 10^5 tons
To combine these masses, we simply add the coefficients:
0.22 + 3.7 = 3.92
For the final answer, we keep the common exponent, which is 10^5, and write the coefficient as 3.92 in scientific notation:
3.92 * 10^5 tons
Therefore, the combined mass of the two skyscrapers is 3.92 * 10^5 tons.
