Ineed a walkthrough on this, i have tonight to get it finished and i'm not sure where to begin..a steel beam can be cut to different lengths for a project. assuming the weight of a steel beam is proportional to its length, what information would you need to know to write an equation that represents this relationship? [following a lesson titled 'solving problems about proportional relationships']

We have been given that the weight of the steel beam is proportional to its length.

Therefore, w ∞ l

or, w = kl, where k is the constant of proportionality.

So, to know the relationship between the weight and the length, we need to know the constant of proportionality.

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
