A certain insect is approximately 4 x 10^-2 inches long. A second insect is about 1.3 x 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)
The total length of the two insects can be found by adding their lengths.
The first insect is approximately 4 x 10^-2 inches long, which can be rewritten as 0.04 x 10^-2 inches.
The second insect is about 1.3 x 10^-1 inches long, which can be rewritten as 0.13 x 10^-1 inches.
Adding these two lengths together, we get 0.04 x 10^-2 inches + 0.13 x 10^-1 inches = 0.17 x 10^-1 inches.
In scientific notation, this can be written as 1.7 x 10^-2 inches.
Therefore, the total length of the two insects is approximately 1.7 x 10^-2 inches.
