Answer:
858
Step-by-step explanation:
Answer:
Option C is the correct answer,
Step-by-step explanation:
The distance of planet Jupiter from the Sun is approximately 7.8 x 10⁸ kilometers.
Distance from Jupiter to Sun = 7.8 x 10⁸ kilometers
The distance of planet Saturn from the Sun is 1.5 x 10⁹ kilometers.
Distance from Saturn to Sun = 1.5 x 10⁹ kilometers
Difference in distances = 1.5 x 10⁹ - 7.8 x 10⁸ = 15 x 10⁸ - 7.8 x 10⁸
Difference in distances = 7.2 x 10⁸ kilometers
Answer: Difference in distances = 7.2 x 10⁸ kilometers
Step-by-step explanation:
Answer: It has two pairs of parallel lines
Step-by-step explanation:
coordinates of E (-4,4) K (4,4) M(-6,-3) I( 2,-3)
The distance from E to K is 8 the same as the distance from M to I.
The distance from M to E is about 7.3 and the distance between K and I is the the same thing.
Answer:
Counting the unit on graph, we observes:
EK = MI = 8
EK // MI // x-axis
=> MEKI is parallelogram
Hope this helps!
