Answer: The copy machine makes 171 copies in 4 minutes and 45 seconds.

Step-by-step explanation:

Let's dissect the question. The copy machine makes 36 copies per minute.

36 per min.

To see how many copies it makes in 4 minutes and 45 seconds, we multiply 36 * 4.75. 45 seconds is 3/4ths of a minute, or 0.75 of a minute.

36 * 4.75=171

It makes 171 copies in 4 minutes and 45 seconds.

Hey guys I need some help. Question in the image below
mafiozo [28]

Answer:

15 students at school

Step-by-step explanation:

So there is 50 students in total

First subtract that much with how much students have the flu

1/10 = 5/50

So 5 students have the flu

That leaves 45 students

Then subtract that much with the amount of students that are remaining are on the field trip

45 divided by 3 = 15

so 2/3 = 30/45 (they can both be multiplied and divided by 15)

so 30 of the 45 students are on the field trip

45 - 30 = 15

That means there are 15 students left over at school

The length of a rectangle is three times the width of the rectangle. The area of the rectangle is 48cm2. Draw the rectangle on t
Schach [20]

Answer:

<em>The width is 4 cm</em>

<em>The length is 12 cm.</em>

Step-by-step explanation:

<u>Area of a rectangle</u>

Given a rectangle of width W and length L, its area is calculated as follows:

A=W\cdot L

The area of the given rectangle is 48 cm^2, and the length is three times the width, thus:

L = 3W

Substituting into the formula of the area:

W\cdot L=48

W\cdot 3W=48

Simplifying:

3W^2=48

Solving:

W^2=48/3=16

W=\sqrt{16}=4

The width is 4 cm. Find the length:

L=3W=3*4= 12

The length is 12 cm.

The image attached shows the rectangle on the centimeter grid
