20. Our Galaxy It is about 30,000 light years from our solar system to the center of the Milky Way Galaxy. The solar system revolves around the center of the Milky Way
with an angular velocity of about 2.6 x 10-* radians per year.
a. What distance does the solar system travel in its orbit each year?
b. Given that a light year is about 5.88 X 10'2 miles, how fast is the solar system
circling the center of the galaxy in miles per hour?

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
