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.
