An astronaut who weighed 150 pounds on earth found that his weight on jupiter was 400 pounds. he captured an alien that weighed 120 pounds on jupiter. what is the alien's weight on earth?

44.98 pounds

Step-by-step explanation:

Weight = mass * acceleration due to gravity

acceleration due gravity (earth) = 9.8 m/s²

Astronaut weight on earth =

W = M * g =》 150 = Mass * 9.8

Mass of the astronaut = 150 / 9.8 = 15.306 pound

His weight in Jupiter became 400 pounds

Acceleration due to gravity on Jupiter?

W = m * g

400 = 15.306 * g

g = 400 / 15.306

g = 26.13 m/s

Acceleration due to gravity on Jupiter = 26.13 m/s

Weight of the alien = 120 pounds

Mass of the alien?

W = m * g

120 = mass * 26.13

Mass = 120 / 26.13 = 4.59 pounds

Weight of the alien on earth = mass * acceleration due to gravity (earth)

W = 4.59 * 9.8

W = 44.98 pounds

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
