A certain insect is approximately 4 x 10^-2 inches long A second insect is about 1.3 * 10 to the negative power of 1 in Long what is the total length of two insects in inches use scientific notation to express your answer to one decimal place
To find the total length of the two insects, we need to add their lengths.
The length of the first insect is 4 x 10^-2 inches.
The length of the second insect is 1.3 x 10^-1 inches.
Adding these two lengths, we get:
4 x 10^-2 + 1.3 x 10^-1
To add these numbers in scientific notation, the exponents must be the same.
We can rewrite 4 x 10^-2 as 0.04 x 10^0, and 1.3 x 10^-1 as 0.13 x 10^0.
Adding these two numbers, we get:
0.04 x 10^0 + 0.13 x 10^0 = 0.17 x 10^0
Since 0.17 x 10^0 is equal to 0.17, we can write the total length as:
0.17 inches.
To find the total length of the two insects, we need to add their lengths together.
First, let's convert the length of the first insect into scientific notation:
4 x 10^-2 inches = 4 * 10^-2 inches
Now, let's convert the length of the second insect into scientific notation:
1.3 x 10^-1 inches = 1.3 * 10^-1 inches
To add the two lengths together, we need to ensure that the exponents are the same:
4 * 10^-2 inches + 1.3 * 10^-1 inches = ?
To do this, we can convert 4 x 10^-2 inches to 40 x 10^-3 inches by moving the decimal point one place to the right.
Now, we have:
40 x 10^-3 inches + 1.3 x 10^-1 inches
To add these two numbers together, we need to add the coefficients (40 and 1.3) while keeping the common exponent of 10^-3:
40 x 10^-3 inches + 1.3 x 10^-1 inches = (40 + 1.3) x 10^-3 inches
Now, let's calculate the sum of the coefficients:
(40 + 1.3) = 41.3
So the total length of the two insects is 41.3 x 10^-3 inches.
Finally, let's express this result in scientific notation with one decimal place:
41.3 x 10^-3 inches = 4.1 x 10^-2 inches.
Therefore, the total length of the two insects, in scientific notation with one decimal place, is 4.1 x 10^-2 inches.
To find the total length of the two insects, we need to add their lengths.
First, let's convert the lengths of both insects to standard scientific notation.
The length of the first insect is approximately 4 x 10^-2 inches. This can be written as 4.0 x 10^-2 inches.
The length of the second insect is about 1.3 x 10^-1 inches.
Now, let's add the two lengths together:
4.0 x 10^-2 inches + 1.3 x 10^-1 inches
To add numbers in scientific notation, we need to ensure that the exponents (powers of 10) are the same. In this case, we need to adjust the first number.
Since 4.0 x 10^-2 = 4.0 x 10^-2 x 10^1 = 4.0 x 10^-1, we can rewrite the addition as:
4.0 x 10^-1 inches + 1.3 x 10^-1 inches
Now, we can add the two lengths:
4.0 x 10^-1 inches + 1.3 x 10^-1 inches = 5.3 x 10^-1 inches
The total length of the two insects is approximately 5.3 x 10^-1 inches.
