Question

The mean distance from the Sun to Earth is 9.29x10^7. Jupiter’s mean distance from the Sun is 4.8388x10^8. What is the difference etween these two distances in miles?
A. 4.3902 x 10^1
B. 5.7678 x 10^8
C. 3.9098 x 10^8
D. 3.9098 x10^7

Answer 1

Answer:

$-3.9098*10^8$

Step-by-step explanation:

1) Convert to Standard Form:

9.29 * 10^7 = 92900000

4.8388 * 10^8= 483880000

2) Subtract 483880000 from 92900000.

$92900000-483880000=-390980000$

3) Convert the difference into scientific notation.

$-390980000= -3.9098 * 10^8$

C would be your best choice.

Answer 2

The difference between the distances of Jupiter and Earth to the Sun is 3.9098 x 10^8 miles, so the correct answer is C.  

Given that the mean distance from the Sun to Earth is 9.29x10 ^ 7, while Jupiter’s mean distance from the Sun is 4.8388x10 ^ 8, to determine what is the difference between these two distances in miles, the following calculation must be performed:

• 9.29 x 10 ^ 7 = X
• 9.29 x 10,000,000 = X
• 92,900,000 = X  
• 4.8388 x 10 ^ 8 = X
• 4.8388 x 100,000,000 = X
• 483,880,000 = X
• 483,880,000 - 92,900,000 = 390,980,000 = 3.9098 × 10^8
