a certain insect is approximately 4*10^-2 inches long a second a second insect is about 1.3*10^-1 inches long what is total length of the two insect 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 individual lengths:

4*10^-2 inches + 1.3*10^-1 inches

To add these numbers in scientific notation, we need to adjust the exponents so that they are the same. In this case, we can convert 4*10^-2 to scientific notation by moving the decimal point two places to the right, resulting in:

0.4*10^-1 inches

Now we can add the two lengths:

0.4*10^-1 inches + 1.3*10^-1 inches = 1.7*10^-1 inches

Therefore, the total length of the two insects is approximately 1.7*10^-1 inches.

To find the total length of the two insects, we need to add their lengths together.

The length of the first insect is approximately 4 * 10^-2 inches.
The length of the second insect is about 1.3 * 10^-1 inches.

Adding these two lengths together:

(4 * 10^-2) + (1.3 * 10^-1)

To add these numbers in scientific notation, we need to make sure the exponents are the same. In this case, we can convert 4 * 10^-2 to scientific notation by moving the decimal point two places to the left, resulting in 4 * 10^-2 = 4 * 10^-2.

Now we can add the values together:

4 * 10^-2 + 1.3 * 10^-1

By rewriting the second value in scientific notation as 13 * 10^-2, we have:

4 * 10^-2 + 13 * 10^-2

Now we can add the coefficients together:

4 + 13 = 17

The common exponent is still 10^-2.

So the total length of the two insects is 17 * 10^-2 inches.

Expressing the answer in scientific notation to 1 decimal place, we can rewrite it as:

1.7 * 10^-1 inches.

To find the total length of the two insects, we need to add their lengths together.

In scientific notation, the first insect is approximately 4 x 10^-2 inches long, and the second insect is about 1.3 x 10^-1 inches long.

To add these numbers, we need to make sure they have the same exponent (power of 10). We can achieve this by converting 4 x 10^-2 to the same exponent as 1.3 x 10^-1, which is 10^-1.

To convert 4 x 10^-2 to 10^-1, we can multiply the numerator and denominator by 10. This gives us (4 x 10^-2) x (10/10) = 40 x 10^-3.

Now we can add the two numbers together:

40 x 10^-3 + 1.3 x 10^-1 = (4 x 10^1) x (10^-3) + 1.3 x 10^-1

Next, we can multiply the coefficients (numbers before the power of 10):

4 x 10^1 = 40

Finally, we add the powers of 10:

40 x 10^-3 + 1.3 x 10^-1 = 40 x 10^-3 x 10^1 + 1.3 x 10^-1

Simplifying further:

40 x 10^-3 x 10^1 + 1.3 x 10^-1 = 40 x 10^-2 + 1.3 x 10^-1

Now, we can add the two lengths:

40 x 10^-2 + 1.3 x 10^-1 = 41.3 x 10^-2

However, we need to express the answer in scientific notation to 1 decimal place. To do this, we can adjust the coefficient:

41.3 x 10^-2 = 4.1 x 10^-1

Therefore, the total length of the two insects is approximately 4.1 x 10^-1 inches.
