A certain insect is approximately 4x10^-2 inches long. A second insect Is about 1.3x10^-1 inches long. What is the total length of the two insects in inches? Use scientific notation to express the answer to 1 decimal place.

Answer 1

To find the total length of the two insects, we need to add their lengths together.

The length of the first insect is 4x10^-2 inches and the length of the second insect is 1.3x10^-1 inches.

Adding these lengths gives us (4x10^-2) + (1.3x10^-1) = 4.0x10^-2 + 1.3x10^-1 = 5.3x10^-1 inches.

Expressed in scientific notation to 1 decimal place, the total length of the two insects is 5.3x10^-1 inches.
