Hello. There was no figure to look at so I plotted all of these points for you. Which one looks like the figure to you? That will be your answer.
Remember, you plot the first number first, which will be along the X axis on a graph. Thats the line that runs right to left.
Then you plot the second number, which will be along the Y axis on a graph.
Thats the line that runs up and down.
If you go down or to the left, you will have a negative point. If you go up or to the right you will have a positive point.
20 miles an hour. 60 miles/3 hours=60 divided by 3=20
Answer:
1800 bricks
Step-by-step explanation:
Given
Sidewalk = 100ft by 4ft
Brick = 8 inches by 4 inches
Required
Determine the minimum number of bricks
First, we need to determine the area of both;
![Sidewalk = 100ft * 4ft](https://tex.z-dn.net/?f=Sidewalk%20%3D%20100ft%20%2A%204ft)
![Sidewalk = 400ft^2](https://tex.z-dn.net/?f=Sidewalk%20%3D%20400ft%5E2)
![Brick = 8in * 4in](https://tex.z-dn.net/?f=Brick%20%3D%208in%20%2A%204in)
![Brick = 32in^2](https://tex.z-dn.net/?f=Brick%20%3D%2032in%5E2)
Number of bricks is calculated as follows;
![Number = \frac{Sidewalk}{Brick}](https://tex.z-dn.net/?f=Number%20%3D%20%5Cfrac%7BSidewalk%7D%7BBrick%7D)
![Number = \frac{400ft^2}{32in^2}](https://tex.z-dn.net/?f=Number%20%3D%20%5Cfrac%7B400ft%5E2%7D%7B32in%5E2%7D)
Convert ft^2 to in^2
![Number = \frac{400 * 144in^2}{32in^2}](https://tex.z-dn.net/?f=Number%20%3D%20%5Cfrac%7B400%20%2A%20144in%5E2%7D%7B32in%5E2%7D)
![Number = \frac{57600in^2}{32in^2}](https://tex.z-dn.net/?f=Number%20%3D%20%5Cfrac%7B57600in%5E2%7D%7B32in%5E2%7D)
![Number = 1800](https://tex.z-dn.net/?f=Number%20%3D%201800)
