9. The theater club of a local high school is planning a production. The amount of time t needed to assemble the set is inversel

Vsevolod [243]

Answer:

The situation that represents this situation is:

$t = \frac{60}{n}$

Step-by-step explanation:

The amount of time t needed to assemble the set is inversely proportional to the number people n working.

This means that:

$t = \frac{k}{n}$

In which k is the constant of proportionality.

Twelve people can assemble the set in 5 hours.

This means that for $n = 12, t = 5$ . We use this to find k.

$t = \frac{k}{n}$

$5 = \frac{k}{12}$

$k = 12*5 = 60$

Write an equation to represent the situation.

$t = \frac{60}{n}$

A line is an undefined term because it

Bond [772]

It is undefined because it is one of the building blocks of geometry.
In order to define a term, we must have a definition of all of the words used to describe it. As this progresses, we would have a never-ending list of words to define; at some point, we must accept a few basic building blocks as being undefined.
