Answer:

2000 times

Step-by-step explanation:

Given

Sara:

Mercury = 3.302 * 10^{23

Saturn = 5.685 * 10^{26

Sam:

Mercury = 3.302 * 10^{29

Saturn = 5.685 * 10^{32

To determine the number of times, the mass of Saturn is greater than the mass of Mercury, we simply do the following:

Times = \frac{Saturn}{Mercury}

Using Sara's measurement; this gives:

Times = \frac{5.685 * 10^{26}}{3.302 * 10^{23}}

Apply law of indices

Times = \frac{5.685 * 10^{26-23}}{3.302}

Times = \frac{5.685 * 10^3}{3.302}

Times = 5.685/3.302 * 10^3

Times = 1.72 * 10^3

Approximate

Times = 2 * 10^3

Times = 2000

Question is in picture<br><br> Drag and drop the steps in order to correctly complete the proof
gavmur [86]

9514 1404 393

Explanation:

The correct order of the steps is ...

  • (Given)
  • (Definition of supplementary)
  • (Substitution)
  • (Subtraction ...)
  • (Definition of congruent angles)

A proof always starts with "given". It always ends with a statement of what you have proved.

To fill in the sequence between these, it helps to think about what the relationships are and why you can conclude that the theorem is correct.
