earth's radius is approximately 3,959 miles, while jupiter's radius is approximately 4.3441 * 10^4 miles. how much bigger is jupiter's radius compared to earth's? express your answer in scientific notation.

Answer 1

To find out how much bigger Jupiter's radius is compared to Earth's, we need to divide Jupiter's radius by Earth's radius.

4.3441 * 10^4 miles / 3,959 miles

To divide these numbers, we subtract the exponents of 10 and divide the base numbers:

4.3441 / 3,959 = 1.0967

Next, we compare the exponents of 10:

10^4 / 10^0 = 10^4

Therefore, Jupiter's radius is 1.0967 * 10^4 times bigger than Earth's radius.

Answer 2

human hair grows at a rate of about 6.849*10^-4 cm per hour to 2.329*10^-2 cm per hour. the rate depends on gender, genetics, age, and health. find the difference between the high end and the low end of the range. express your answer in scientific notation. do not round your answer

Answer 3

To find the difference between the high end and the low end of the range, we subtract the low end from the high end.

High end: 2.329 * 10^-2 cm per hour
Low end: 6.849 * 10^-4 cm per hour

2.329 * 10^-2 - 6.849 * 10^-4

To subtract these numbers, we need to make sure the exponents of 10 are the same. We can do this by converting both numbers to the same power of 10, which in this case will be 10^-4.

2.329 * 10^-2 = 2.329 * 10^-4 * 10^2
6.849 * 10^-4 = 6.849 * 10^-4 * 10^0

Now we can subtract:

2.329 * 10^-4 * 10^2 - 6.849 * 10^-4 * 10^0

Taking out the common factor of 10^-4:

10^-4 * (2.329 * 10^2 - 6.849 * 10^0)

2.329 * 10^2 - 6.849 * 10^0 = 2.329 * 100 - 6.849

= 232.9 - 6.849

= 226.051

Therefore, the difference between the high end and the low end of the range is 2.26051 * 10^2 cm per hour.
