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.
Just gonna put the answers here because the bot is dumb.
1. 9.1 x 10^7
2. 3.58 x 10^6
3. 2.953 x 10^5 pounds
4. 447,000,000,000
5. 5.12 x 10^11
Don't always trust the bot as it can give incorrect answers.
To find the combined mass of the two skyscrapers, we can simply add their masses together.
The mass of the first skyscraper is 2.2×10^5 tons.
The mass of the second skyscraper is 3.7×10^5 tons.
Adding these two masses together gives us:
(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.
To find the total length of the two insects, we can simply add their lengths together.
The length of the first insect is 4×10^−2 inches.
The length of the second insect is 1.3×10^−1 inches.
Adding these two lengths together gives us:
(4×10^−2) + (1.3×10^−1) = 1.7×10^−1
Therefore, the total length of the two insects is 1.7×10^−1 inches.
Apologies for the incorrect response.
To find the sum of 6.3×10^3 and 2.41×10^4, we need to make sure that the exponents (powers of 10) are the same.
We can rewrite 6.3×10^3 as 0.63×10^4 since 3.3×10^3 is equal to 0.33×10^4.
Now we have:
0.63×10^4 + 2.41×10^4 = 0.63×10^4 + 2.41×10^4 = 3.04×10^4
Therefore, the sum of 6.3×10^3 and 2.41×10^4 is 3.04×10^4.
To find the area of the Canadian football field, we need to add the additional area to the American football field.
The American football field has an area of 6.4×10^3 square yards.
The Canadian football field is 3,350 square yards larger.
Adding the additional area to the American football field gives us:
6.4×10^3 + 3,350 = 6.4×10^3 + 3.35×10^3
Now we can add the coefficients:
6.4 + 3.35 = 9.75
The final answer, expressed in scientific notation to 2 decimal places, is:
9.75×10^3 square yards.
To find the thickness of a fingernail, we need to add the additional thickness to the diameter of a human hair.
The human hair has a diameter of about 4×10^−3 inches.
The fingernail is about 0.011 inches thicker.
Adding the additional thickness to the diameter of the hair gives us:
4×10^−3 + 0.011 = 0.011 + 0.004
Now we can add the coefficients:
0.011 + 0.004 = 0.015
The thickness of a fingernail is approximately 0.015 inches.
