Question

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.

Answer 1

To find the total length of the two insects, we need to add the lengths of the insects together. The length of the first insect is 4×10^(-2) inches and the length of the second insect is 1.3×10^(-1) inches.

Adding these two lengths together, we get:

4×10^(-2) + 1.3×10^(-1) = 0.04 + 0.13 = 0.17

Since both numbers are already in scientific notation, we don't need to convert them.

Therefore, the total length of the two insects is 0.17 inches.

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

The first insect is approximately 4×10^−2 inches long, which can be written as 0.04 inches in decimal form.

The second insect is about 1.3×10^−1 inches long, which can be written as 0.13 inches in decimal form.

Now, we can add the lengths:

0.04 + 0.13 = 0.17

Therefore, the total length of the two insects is approximately 0.17 inches. In scientific notation, this can be written as 1.7×10^−1 inches.

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

The length of the first insect is approximately 4×10^−2 inches.

The length of the second insect is about 1.3×10^−1 inches.

To add these two values, you first need to make sure that the exponents of the scientific notation are the same. In this case, both numbers are already written in scientific notation, so no conversion is necessary.

Now you can directly add the coefficients:

4 + 1.3 = 5.3

To maintain the scientific notation, the common exponent should be used, which in this case is 10^−2.

Thus, the total length of the two insects is approximately 5.3×10^−2 inches.
