To determine the total length of the two insects, we add their lengths: $4\times10^{-2}$ inches + $1.3\times10^{-1}$ inches = $4\times10^{-2} + 1.3\times10^{-1} = 4.0\times10^{-2} + 1.3\times10^{-1} = \boxed{1.7\times10^{-1}}$.
What
We can rewrite the numbers in scientific notation as $4\times10^{-2}$ and $1.3\times10^{-1}$.
To add the two numbers, we need to make sure they have the same exponent. We can rewrite $4\times10^{-2}$ as $4\times10^{-2}\times10^{1} = 4\times10^{-2+1} = 4\times10^{-1}$.
Now that the exponents are the same, we can add the two numbers: $4\times10^{-1} + 1.3\times10^{-1} = 5.3\times10^{-1}$.
Therefore, the total length of the two insects is $\boxed{5.3\times10^{-1}}$ inches.
To add the two numbers, we need to make sure they have the same exponent. We can rewrite $4\times10^{-2}$ as $4\times10^{-2}\times10^{1} = 4\times10^{-2+1} = 4\times10^{-1}$.
Now that the exponents are the same, we can add the two numbers: $4\times10^{-1} + 1.3\times10^{-1} = 5.3\times10^{-1}$.
Therefore, the total length of the two insects is $\boxed{5.3\times10^{-1}}$ inches.
Makes no sense
I apologize for the confusion. Let's approach the problem step by step.
The length of the first insect is approximately $4\times10^{-2}$ inches.
The length of the second insect is approximately $1.3\times10^{-1}$ inches.
To find the total length of the two insects, we add their lengths:
$(4\times10^{-2}) + (1.3\times10^{-1})$
To add these numbers, we need to have the same exponent. We can rewrite $4\times10^{-2}$ as $0.04\times10^{-1}$.
Now, we can add the two numbers: $(0.04\times10^{-1}) + (1.3\times10^{-1}) = 0.04\times10^{-1} + 1.3\times10^{-1} = 1.34\times10^{-1}$.
Therefore, the total length of the two insects is $\boxed{1.34\times10^{-1}}$ inches.
The length of the first insect is approximately $4\times10^{-2}$ inches.
The length of the second insect is approximately $1.3\times10^{-1}$ inches.
To find the total length of the two insects, we add their lengths:
$(4\times10^{-2}) + (1.3\times10^{-1})$
To add these numbers, we need to have the same exponent. We can rewrite $4\times10^{-2}$ as $0.04\times10^{-1}$.
Now, we can add the two numbers: $(0.04\times10^{-1}) + (1.3\times10^{-1}) = 0.04\times10^{-1} + 1.3\times10^{-1} = 1.34\times10^{-1}$.
Therefore, the total length of the two insects is $\boxed{1.34\times10^{-1}}$ inches.
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.
To find the total length of the two insects, we simply add their lengths:
$4\times10^{-2}$ inches + $1.3\times10^{-1}$ inches
We can add these numbers by converting them to the same power of 10:
$4\times10^{-2} = 0.04\times10^{-1}$ inches
Now we can add the lengths:
$0.04\times10^{-1}$ inches + $1.3\times10^{-1}$ inches = $0.04 + 1.3 \times10^{-1}$ inches
We can rewrite $1.3 \times10^{-1}$ as $0.13 \times 10^{-1}$:
$0.04 + 0.13 \times 10^{-1}$ inches
Now we can add the decimal numbers:
$0.04 + 0.13 = 0.17$
The sum of the decimal numbers is 0.17. The exponent remains the same, $10^{-1}$. Therefore, the total length of the two insects is $\boxed{0.17 \times 10^{-1}}$ inches.
$4\times10^{-2}$ inches + $1.3\times10^{-1}$ inches
We can add these numbers by converting them to the same power of 10:
$4\times10^{-2} = 0.04\times10^{-1}$ inches
Now we can add the lengths:
$0.04\times10^{-1}$ inches + $1.3\times10^{-1}$ inches = $0.04 + 1.3 \times10^{-1}$ inches
We can rewrite $1.3 \times10^{-1}$ as $0.13 \times 10^{-1}$:
$0.04 + 0.13 \times 10^{-1}$ inches
Now we can add the decimal numbers:
$0.04 + 0.13 = 0.17$
The sum of the decimal numbers is 0.17. The exponent remains the same, $10^{-1}$. Therefore, the total length of the two insects is $\boxed{0.17 \times 10^{-1}}$ inches.
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.
To find the total length of the two insects, we add their lengths: $4\times10^{-2}$ inches + $1.3\times10^{-1}$ inches.
To add them, we need to make sure their exponents are the same. We can rewrite $4\times10^{-2}$ as $0.04\times10^{0}$ inches.

Wrong
I apologize for the previous incorrect responses. Let's try again.
The length of the first insect is approximately $4\times10^{-2}$ inches.
The length of the second insect is about $1.3\times10^{-1}$ inches.
To find the total length of the two insects, we add their lengths:
$4\times10^{-2}$ inches + $1.3\times10^{-1}$ inches
To add these, we need to convert the lengths to the same exponent. We can rewrite $4\times10^{-2}$ in scientific notation as $0.04\times10^{-1}$ inches.
Now, we can add the two lengths:
$0.04\times10^{-1}$ inches + $1.3\times10^{-1}$ inches = $0.04\times10^{-1} + 1.3\times10^{-1}$ inches
Adding the decimal values, we have:
$0.04 + 1.3 = 1.34$
The sum of the decimal values is 1.34. The exponent remains the same, $10^{-1}$.
Therefore, the total length of the two insects is $\boxed{1.3\times10^{-1}}$ inches.
The length of the first insect is approximately $4\times10^{-2}$ inches.
