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.
