To find the total length of the two insects, we 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 lengths gives us (4 × 10^(-2)) + (1.3 × 10^(-1)) inches.
To express this answer in scientific notation with one decimal place, we need to adjust the decimal point to have one digit to the left.
4 × 10^(-2) inches is equivalent to 0.4 × 10^(-1) inches.
Therefore, the total length of the two insects and 6 inches is (0.4 × 10^(-1)) + (1.3 × 10^(-1)) inches.
Adding these lengths gives us 0.7 × 10^(-1) inches.
In scientific notation with one decimal place, the total length is 0.7 × 10^(-1) inches.
