Axel is getting his pig ready for the pig races at the county fair. During the race, four juvenile pigs run along a straight track, trying to be the first pig to get to a cream-filled chocolate cookie. His pig, Hammy, can run at a rate of feet per second.

At this speed, how far will Hammy run in seconds? In seconds? In minute (which is the same as seconds)?

Write an expression that represents how far Hammy will run in seconds.

The race track at the fair is feet long.

Draw a diagram that shows how long it will take Hammy to finish the race.

Write an equation to represent this situation.

About how long it will take Hammy to finish the race?

step-by-step explanation:

hello!

to begin with, we're given that on earth, a rock weighs 20 pounds, and while on jupiter, that same rock weighs 42 pounds. now, we're trying to find the weight of a rock that weighs 10.5 pounds on earth, on jupiter.

to solve this, first, set up a proportion, cross-multiply, and solve it algebraically.

setting up the proportion is the hardest and the most confusing part of the problem, but it's simple.

if on earth, the rock weighs 20 lbs, and on jupiter it weighs 42 lbs, our first part of our proportion is 20/42 lbs. the second part has to be equal to each other. this means that 10.5 has to be on the numerator of the fraction, and x, the value we're trying to find, has to be on the denominator. remember that the rock weighs 10.5 lbs on earth, and we're trying to find the weight of it on jupiter (which is x).

20/42 = 10.5/x

next, you would cross-multiply.

20x = 42(10.5)

20x = 441

now, solve it algebraically by using division.

x = 22.05 lbs

this can be rounded to 22.1 lbs.

therefore, the weight of the rock on jupiter is 22.1 lbs, the fourth choice.
