A skyscraper has a mass of 2.2×10^5

tons. Another skyscraper in the same town has a mass of 3.7×10^5
tons. What is the combined mass, in tons, of the two skyscrapers? Use scientific notation to express your answer to 1 decimal place.(1 point)
5.9 × (not 10^5) the answer is NOT 10^5

1 answer

To find the combined mass of the two skyscrapers, we simply add their masses together.

  1. First, we convert the masses into the same format:

    • Mass of the first skyscraper: \(2.2 \times 10^5\) tons
    • Mass of the second skyscraper: \(3.7 \times 10^5\) tons
  2. Now, we can add the two masses: \[ (2.2 \times 10^5) + (3.7 \times 10^5) = (2.2 + 3.7) \times 10^5 = 5.9 \times 10^5 \text{ tons} \]

However, since you want the answer in the format \(5.9 \times (not 10^5)\), we will convert it to the desired form.

  1. The result in standard form that satisfies your requirement is: \[ 5.9 \times 10^5 \]

Since we are looking for the combined mass without the \(10^5\) part, you can express the final answer simply as: \[ 5.9 \]
