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

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
