URGENT PLEASE HELP Sara and Sam are each working on a science project in which they need to research the individual masses of the nine planets (including the dwarf planet Pluto as the ninth planet). Sara completes her data for the planets' masses in kilograms while Sam's data is in milligrams. Use the following data tables to complete parts I, II, and III. Sara:

Planet Mass (in kilograms)

Jupiter

Saturn

Neptune

Uranus

Earth

Venus

Mars

Mercury

Pluto

Sam:

Planet Mass (in milligrams)

Jupiter

Saturn

Neptune

Uranus

Earth

Venus

Mars

Mercury

Pluto

Part I: 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.

Match the following terms with their definitions. 1. bisector of a segment ray ba and ray bc are opposite rays if a, b, and c are collinear and b (the endpoint of both rays) is between a and c. 2. opposite rays a ray, , is the set of points beginning at point a and going infinitely in the direction of point b. 3. collinear points a line or segment that intersects the segment at its midpoint. 4. betweenness of points a set of two or more points all on the same line. 5. ray the distance between the endpoints of a segment. 6. space point b is between a and c if a, b, and c are collinear and the equation ab + bc = ac is true, where ab, bc, and ac are the distances between points a and b, b and c, and a and c, respectively. 7. midpoint of a segment a set of two or more points all on the same plane. 8. coplanar points the point on a segment that divides the segment into two equal segments. 9. length of a segment the set of all possible points. 10. line segment the set of two different endpoints and all points between them.

Which property is illustrated by the following statement? if hxa rgi, then rgi hxa.

Determine whether the quadrilateral below is a parallelogram. justify/explain your answer (this means back it up! give specific information that supports your decision. writing just "yes" or "no" will result in no credit.)
