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 sciencetific notation to express your answer to 1 decimal place
To find the total length of the two insects, we add their lengths together.
4 x 10^-2 inches + 1.3 x 10^-1 inches = (0.4 + 1.3) x 10^-1 inches
Simplifying the decimal part, we get:
(1.7) x 10^-1 inches
So the total length of the two insects is approximately 1.7 x 10^-1 inches.
To find the total length of the two insects, we need to add their lengths.
1. Convert the lengths to scientific notation:
- The first insect: 4 x 10^-2 inches
- The second insect: 1.3 x 10^-1 inches
2. Add the lengths:
(4 x 10^-2 inches) + (1.3 x 10^-1 inches)
3. Before adding, we need to align the exponents. We can do this by converting the first insect's length to have the same exponent as the second insect:
(4 x 10^-2 inches) = (0.04 x 10^0 inches) = 0.04 inches
4. Now we can add the lengths:
0.04 inches + (1.3 x 10^-1 inches)
5. Add the decimal numbers:
0.04 + 1.3 = 1.34
6. The sum is 1.34 inches.
Therefore, the total length of the two insects is approximately 1.3 inches, expressed in scientific notation as 1.3 x 10^0 inches.
To find the total length of the two insects, we need to add their lengths. Both lengths are given in scientific notation.
The first insect is approximately 4 x 10^-2 inches long, which can be written as 0.04 inches.
The second insect is about 1.3 x 10^-1 inches long, which can be written as 0.13 inches.
Now, we can simply add the two lengths together to find the total length:
0.04 inches + 0.13 inches = 0.17 inches.
Therefore, the total length of the two insects is approximately 0.17 inches.
