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
To find the total length of the two insects, we need to add their lengths together.
The first insect is 4 x 10^-2 inches long, and the second insect is 1.3 x 10^-1 inches long.
We can convert both these lengths to scientific notation by moving the decimal point to the left so that we have a number between 1 and 10.
The first insect's length becomes 4 x 10^-2 = 0.04 inches.
The second insect's length becomes 1.3 x 10^-1 = 0.13 inches.
To find the total length, we add these two lengths together:
0.04 + 0.13 = 0.17 inches.
The total length of the two insects is 0.17 inches or 1.7 x 10^-1 inches.
To find the total length of the two insects, we will add their lengths together.
Given:
Length of first insect = 4 x 10^-2 inches
Length of second insect = 1.3 x 10^-1 inches
Step 1:
Convert both lengths to decimal notation.
Length of first insect = 0.04 inches (4 x 10^-2 = 0.04)
Length of second insect = 0.13 inches (1.3 x 10^-1 = 0.13)
Step 2:
Add the lengths of the two insects together.
Total length = 0.04 inches + 0.13 inches = 0.17 inches
Step 3:
Express the total length in scientific notation to 1 decimal place.
Total length = 1.7 x 10^-1 inches
To find the total length of the two insects, we need to add their lengths together. Let's start by representing the lengths of the insects in scientific notation.
The first insect is approximately 4 x 10^-2 inches long, which can be written as 4 * 10^-2.
The second insect is about 1.3 x 10^-1 inches long, which can be written as 1.3 * 10^-1.
To add these two numbers, we need to make sure that the exponents are the same. In this case, the exponents are both -2 and -1, so we're good to go.
Adding the numbers, we get:
4 * 10^-2 + 1.3 * 10^-1 = 0.04 + 0.13 = 0.17
So, the total length of the two insects is 0.17 inches.
