Jeffrey is using a copy machine to make posters for a school play. The machine prints the posters at a constant rate. After 3 mi
jasenka [17]

Answer:

B: 11 minutes.

Step-by-step explanation:

So, we know that the machine prints at a constant rate.

After 3 minutes, the machine prints 108 posters.

So, let’s find the <em>unit rate. </em>We will divide the output over the input. So:

108\text{ posters}/3\text{ minutes}=36\text{ posters/min}

So, the unit rate of the machine is 36 posters per minute.

We can write an equation. If t represent the number of minutes and p represent the amount of posters, then:

p=36t

Gives the amount of posters p and t minutes.

We want to know how long it will take Jeffrey to make 396 posters.

So, we can substitute 396 for p and solve for t. Hence:

396=36t

Divide both sides by 36:

t=11

Therefore, it will take Jeffrey 11 minutes to make 396 posters.

<em>The question is incomplete has the figure of the triangle is not given.</em>

<em>However, the following steps will guide you.</em>

To solve this question;

you need the lengths of the threes sides of the triangular fields

Represent these lengths with a, b and c

Next;

Sum these lengths together;

This gives the required length of fencing

Length = a + b + c
