A skyscraper has a mass of 2.2×10 to the fifth power tons. Another skyscraper in the same town has a mass of 3.7 times 10 to the fifth power times what is the combined mass and tons of the two skyscrapers you scientific notation to express your answer to the first decimal place
To find the combined mass of the two skyscrapers, we need to add their masses together.
The first skyscraper has a mass of 2.2×10^5 tons.
The second skyscraper has a mass of 3.7 × 10^5 tons.
To add these together, we add the coefficients and keep the same exponent:
2.2×10^5 + 3.7 × 10^5 = 5.9 × 10^5
Therefore, the combined mass of the two skyscrapers is 5.9×10^5 tons, using scientific notation with one decimal place.
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 × 10^5 tons.
The second skyscraper has a mass of 3.7 × 10^5 tons.
Adding these two masses together, we get:
2.2 × 10^5 + 3.7 × 10^5 = (2.2 + 3.7) × 10^5 = 5.9 × 10^5 tons
Therefore, the combined mass of the two skyscrapers is 5.9 × 10^5 tons.
To find the combined mass of the two skyscrapers, we need to add their masses together. Let's start by converting the masses of the skyscrapers to the same unit.
The first skyscraper has a mass of 2.2 × 10^5 tons. This is already given in tons.
The second skyscraper has a mass of 3.7 × 10^5 times something. To find the mass in tons, we need to multiply this value by 10^5.
3.7 × 10^5 × 10^5 = 3.7 × (10^5 × 10^5) = 3.7 × 10^(5+5) = 3.7 × 10^10
So, the mass of the second skyscraper is 3.7 × 10^10 tons.
Now, we can add the masses of the two skyscrapers together:
2.2 × 10^5 + 3.7 × 10^10
To simplify the calculation, we can rewrite the masses in scientific notation with the same exponent:
2.2 × 10^5 = 2.2 × 10^5 × 10^10 / 10^10 = 2.2 × 10^(5+10)
Now, we can add the masses:
2.2 × 10^(5+10) + 3.7 × 10^10 = 2.2 × 10^15 + 3.7 × 10^10
Adding these values gives us the combined mass of the two skyscrapers.
Using scientific notation to express the answer to the first decimal place, we have:
(2.2 × 10^15) + (3.7 × 10^10) = 2.2 × 10^15 (rounded to the first decimal place)
