3. The average distance from the sun to the planet Jupiter is about 483,800.000. The average
MArishka [77]

Answer:

The answer to your question is:

a) sun to jupiter =  4.838 x 10 ⁸ miles

   sun to earth = 9.296 x 10 ⁷ miles

b) 5.2 times

Step-by-step explanation:

distance sun to jupiter = 483 800 000 miles

distance sun to earth = 92 960 000 miles

a)

      sun to jupiter =  4.838 x 10 ⁸ miles  just move the decimal point eight places to the left.

      sun to earth = 9.296 x 10 ⁷ miles   just move the decimal point seven places to the left.

b)

divide distance sun to jupiter by distance sun to earth =

                                  = 4.838 x 10 ⁸ / 9.296 x 10 ⁷

                                 

First divide   4.838 by 9.296    or   4.838 / 9.296 = 0.52

Then we substract the powers:  8 minus 7  or 8 -7 = 1

So we get              0.52 x 10¹  or 0.52 x 10 = 5.2 times

Angles on a straight line add up to 180 degrees.
180-100 = 80
x + 3x = 4x
80/4 = 20
x = 20 degrees
