Part 1: Although both data tables represent correct data for each of the planet's masses, who represented Jupiter's mass with the most appropriate units, Sara or Sam?
Part II: In two or more complete sentences, explain your reasoning for your answer in Part I.
Part III: Use multiplication, division, and scientific notation to show that Sara's representation of Jupiter's mass in
kilograms is equal to Sam's representation of Jupiter's mass in milligrams.
1. Use milligrams to prove that 1.989. 1027 kilograms is equal to 1.989. 1033 milligrams.
2. Use kllograms to prove that 1.989.1033 milligrams is equal to 1.989.1027 kilograms

answer: entity is prob the answer

step-by-step explanation:

hello!

to begin with, we're given that on earth, a rock weighs 20 pounds, and while on jupiter, that same rock weighs 42 pounds. now, we're trying to find the weight of a rock that weighs 10.5 pounds on earth, on jupiter.

to solve this, first, set up a proportion, cross-multiply, and solve it algebraically.

setting up the proportion is the hardest and the most confusing part of the problem, but it's simple.

if on earth, the rock weighs 20 lbs, and on jupiter it weighs 42 lbs, our first part of our proportion is 20/42 lbs. the second part has to be equal to each other. this means that 10.5 has to be on the numerator of the fraction, and x, the value we're trying to find, has to be on the denominator. remember that the rock weighs 10.5 lbs on earth, and we're trying to find the weight of it on jupiter (which is x).

20/42 = 10.5/x

next, you would cross-multiply.

20x = 42(10.5)

20x = 441

now, solve it algebraically by using division.

x = 22.05 lbs

this can be rounded to 22.1 lbs.

therefore, the weight of the rock on jupiter is 22.1 lbs, the fourth choice.
