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 simply add their lengths:
4 x 10^-2 + 1.3 x 10^-1
To simplify this, we need to make sure the exponents are the same. We can do this by converting 4 x 10^-2 to scientific notation with an exponent of -1:
4 x 10^-2 = 4 x 10^(-2 + 1) = 4 x 10^-1
Now, we can add the two lengths:
4 x 10^-1 + 1.3 x 10^-1 = (4 + 1.3) x 10^-1
= 5.3 x 10^-1
= 5.3 x 10^-0.5 (one decimal place)
Therefore, the total length of the two insects is approximately 5.3 x 10^-0.5 inches.
To find the total length of the two insects in inches, we need to add the lengths together. The first insect is approximately 4 x 10^-2 inches long, and the second insect is about 1.3 x 10^-1 inches long.
Let's express both lengths in scientific notation:
First insect: 4 x 10^-2 inches
Second insect: 1.3 x 10^-1 inches
Now, we can add them:
(4 x 10^-2 inches) + (1.3 x 10^-1 inches)
To do the addition, we need to make sure both numbers are written with the same power of 10. Let's convert 4 x 10^-2 inches to a number with the same exponent as 10^-1:
4 x 10^-2 inches = 0.04 x 10^-1 inches
Now, we can add them:
(0.04 x 10^-1 inches) + (1.3 x 10^-1 inches)
Combining the terms with the same exponent, we get:
(0.04 + 1.3) x 10^-1 inches
Calculating the sum, we get:
1.34 x 10^-1 inches
Therefore, the total length of the two insects is 1.3 x 10^-1 inches, expressed in scientific notation to 1 decimal place.
To find the total length of the two insects, we simply need to add their lengths together.
The first insect is approximately 4 x 10^-2 inches long, which is the same as 0.04 inches in decimal form.
The second insect is about 1.3 x 10^-1 inches long, which is equivalent to 0.13 inches in decimal form.
Adding these two lengths together, we have:
0.04 inches + 0.13 inches = 0.17 inches
Therefore, the total length of the two insects is approximately 0.17 inches.
