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. (1 point)
To find the total length of the two insects, we need to add their lengths.
The length of the first insect is 4 * 10^(-2) inches.
The length of the second insect is 1.3 * 10^(-1) inches.
To add these two lengths, we need to ensure they have the same exponent.
4 * 10^(-2) = 0.04 * 10^0
1.3 * 10^(-1) = 0.13 * 10^0
Now, we can add their lengths:
0.04 * 10^0 + 0.13 * 10^0 = 0.17 * 10^0
We can rewrite 10^0 as 1, so we have:
0.17 * 1 = 0.17
Therefore, the total length of the two insects is 0.17 inches.
Your wrong
I apologize for the mistake. Let's correct it:
The length of the first insect is 4 * 10^(-2) inches, which is equal to 0.04 inches.
The length of the second insect is 1.3 * 10^(-1) inches, which is equal to 0.13 inches.
To find the total length, we add the lengths of the two insects:
0.04 inches + 0.13 inches = 0.17 inches
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 these two lengths together:
0.04 inches + 0.13 inches = 0.17 inches
So, the total length of the two insects is approximately 0.17 inches.
