Question

9. The number of possible string sections (s) to be cut from a 4-inch piece of string variesinversely with the length (/) of each of these string sections. Which equation models thisrelationship?

Answer 1

`s=(4)/(l)`

Step-by-step explanation

We want to find the equation that models the relationship.

An inverse proportional relationship is generally given as:

`y=(k)/(x)`

where k = constant of proportionality

x and y = variables that are related

Therefore, given that the number of possible string sections, s, varies inversely with the length, l, the only option that is in this form is:

`s=(4)/(l)`

That is the correct answer.
