A certain insect is approximately 4x10^-2 inches long. A second insect Is about 1.3x10^-1 inches long. What is the total length of the two insects in inches? Use scientific notation to express the answer to 1 decimal place.
To find the total length of the two insects, we can add their lengths together.
The first insect is approximately 4x10^(-2) inches long.
The second insect is about 1.3x10^(-1) inches long.
Let's add these two lengths together:
4x10^(-2) + 1.3x10^(-1)
To add numbers in scientific notation, we need to make sure the exponents are the same.
To do this, we can convert 4x10^(-2) to have an exponent of -1 by moving the decimal point one place to the right:
4x10^(-2) = 0.4x10^(-1)
Now, let's add the lengths:
0.4x10^(-1) + 1.3x10^(-1) = 1.7x10^(-1)
Therefore, the total length of the two insects is approximately 1.7x10^(-1) inches, which is expressed in scientific notation.
To find the total length of the two insects, we need to add their lengths together.
The first insect is approximately 4x10^-2 inches long: 4x10^-2 = 0.04 inches in scientific notation.
The second insect is about 1.3x10^-1 inches long: 1.3x10^-1 = 0.13 inches in scientific notation.
Now, we can add the lengths to get the total length: 0.04 + 0.13 = 0.17 inches.
Expressing the answer to 1 decimal place, the total length of the two insects is approximately 0.2 inches.
To find the total length of the two insects, we need to add their lengths together.
The length of the first insect is 4x10^-2 inches and the length of the second insect is 1.3x10^-1 inches.
Adding these lengths gives us (4x10^-2) + (1.3x10^-1) = 4.0x10^-2 + 1.3x10^-1 = 5.3x10^-1 inches.
Expressed in scientific notation to 1 decimal place, the total length of the two insects is 5.3x10^-1 inches.
