a certain insect is approximately 4*10^-2 inches long a second a second insect is about 1.3*10^-1 inches long what is total length of the two insect in inches use scientific notation to express your answer to 1 decimal place

Answer 1

To find the total length of the two insects, we need to add their individual lengths:

4*10^-2 inches + 1.3*10^-1 inches

To add these numbers in scientific notation, we need to adjust the exponents so that they are the same. In this case, we can convert 4*10^-2 to scientific notation by moving the decimal point two places to the right, resulting in:

0.4*10^-1 inches

Now we can add the two lengths:

0.4*10^-1 inches + 1.3*10^-1 inches = 1.7*10^-1 inches

Therefore, the total length of the two insects is approximately 1.7*10^-1 inches.
