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 mads in tons of the two skyscrapers? use scientific notion to express your answer to 1 decimal place
To find the combined mass of the two skyscrapers, you can add their masses together.
Given:
Mass of the first skyscraper = 2.2 x 10^5 tons
Mass of the second skyscraper = 3.7 x 10^5 tons
Adding the two masses together:
2.2 x 10^5 + 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.
A certain insect is approximately 4 × 10^-2 inches long. A second insect is about 1.3 × 10^-1 inches long. What is the total length of the two insects in inches? Use scientific notation to express your answer to 1 decimal place. (1 point)
To find the total length of the two insects, you can add their lengths together.
Given:
Length of the first insect = 4 × 10^-2 inches
Length of the second insect = 1.3 × 10^-1 inches
Adding the two lengths together:
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.
what isvthe sum of 6.3 x 10^3? use scientific notion to express your answer
To find the sum of 6.3 x 10^3, you can simply express it in scientific notation.
6.3 x 10^3 can be written as 6.3 x 1000, since 10^3 = 1000.
Therefore, the sum of 6.3 x 10^3 is 6.3 x 1000, which can be expressed in scientific notation as 6.3 x 10^4.
OOPS
what isvthe sum of 6.3 x 10^3 and 2.41 x 10^4?? use scientific notion to express your answer
To find the sum of 6.3 x 10^3 and 2.41 x 10^4, you can add them together.
6.3 x 10^3 + 2.41 x 10^4 = 6.3 x 1000 + 2.41 x 10000
Simplifying further:
= 6300 + 24100
= 30400
Therefore, the sum of 6.3 x 10^3 and 2.41 x 10^4 is 3.04 x 10^4.
An American football field has an area of 6.4 ×
10^3 square yards. A Canadian football field is 3,350 square yards larger.
What is the area of a Canadian football field? Write your answer in scientific notation to 2 decimal places. (1 point)
To find the area of the Canadian football field, you can add the difference in areas to the area of the American football field.
Given:
Area of the American football field = 6.4 × 10^3 square yards
Difference in area = 3,350 square yards
Adding the two areas together:
6.4 × 10^3 + 3,350 = 6.4 × 10^3 + 3.35 × 10^3
= 9.75 × 10^3
Therefore, the area of the Canadian football field is 9.75 × 10^3 square yards.
A human hair has a diameter of about 4 x 10^3 inches. A fingernail is about 0.011 inches thicker. How thick is a fingernail? Write your answer as a decimal to 3 places. (1 point)
To find the thickness of a fingernail, you can add the difference in thickness to the diameter of a hair.
Given:
Diameter of a hair = 4 x 10^3 inches
Difference in thickness = 0.011 inches
Adding the two measurements together:
4 x 10^3 + 0.011 = 4 x 10^3 + 0.011
= 4.011
Therefore, the thickness of a fingernail is 4.011 inches.
A mobile phone holds 1.28 × 10^11 bytes of storage. You can also pay more money to get an additional 384,000,000,000 bytes. How much storage would your phone have if you buy the additional bytes? The answer should be in scientific notation. (1 point)
To find the total storage of the phone after buying the additional bytes, you can add the additional bytes to the existing storage.
Given:
Existing storage: 1.28 × 10^11 bytes
Additional bytes: 384,000,000,000 bytes
Adding the two together:
1.28 × 10^11 + 384,000,000,000 = 1.28 × 10^11 + 3.84 × 10^11
= 5.12 × 10^11
Therefore, the phone would have a total storage of 5.12 × 10^11 bytes after buying the additional bytes.
