If the perimeter is 30
and the length is twice the width
c=length
w=width
2c=w
a pool table has 4 sides, the two adjacent sides will be equal so we only need to account for 1 of the widths and 1 of the lengths
meaning we only need to use half of the perimeter, or 15
if the length is twice as long as the width
the length would be 10
the width would be 5
there are two widths and 2 heights so the perimeter would correctly add up to 30 feet, proving you have the right answer
Answer: The experimental probability of 2/9
Step-by-step explanation:
2/18= 1/9 * 2= 2/9 so on the first try,she sold 2 out of 18 which means the experimental probability is 2/18 = 1/9 so since this is the second try, you will have to multiply 1/9 by 2 to find the next possible outcome.
Answer: terminating decimal

Answer:
![slope=\frac{1}{4}](https://tex.z-dn.net/?f=slope%3D%5Cfrac%7B1%7D%7B4%7D)
Step-by-step explanation:
The slope of a line can be seen as:
![\frac{rise}{run}](https://tex.z-dn.net/?f=%5Cfrac%7Brise%7D%7Brun%7D)
Rise over run is the change in the y values over the change in x values. For example, in this graph, you would start on one of the points given. From there, you would move up first. After moving up a certain number of spaces, you would move to the side until you reach the other point.
In the graph, you would move up until you are in line with one of the other points. Starting at (-4,5), move up one space, then to the left 4 spaces to reach the point (0,6). Using the spaces moved in the rise over run:
![\frac{1}{4} =\frac{rise}{run}=slope](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20%3D%5Cfrac%7Brise%7D%7Brun%7D%3Dslope)
Therefore, the slope is
.
This is true for any two points on the line.
:Done
*When you move up, the number will be positive
. If you move down, the number will be negative
. If you move left, the number will be positive
. If you move right, the number will be negative
. Keep this in mind. It is very important.
**Always <em>move along the y-axis first</em>, then move along the x-axis. If you do it the other way, the slope will be wrong.
