The distance of a door knob from the floor is about one hip I guess
Radius- 5
The radius is half, so if you want to find the radius, you have to see what if half of the diameter, which is 10. So 10 divided by 2 is 5 which is the radius. Easy.
Answer:
![a.\ m=2,\ \text{the line is rising}\\\\b.\ m=-\dfrac{5}{4},\ \text{the line is falling}\\\\c.\ m=0,\ \text{the line is horizontal}\\\\d.\ m\ is\ unde fined,\ \text{the line is vertical}](https://tex.z-dn.net/?f=a.%5C%20m%3D2%2C%5C%20%5Ctext%7Bthe%20line%20is%20rising%7D%5C%5C%5C%5Cb.%5C%20m%3D-%5Cdfrac%7B5%7D%7B4%7D%2C%5C%20%5Ctext%7Bthe%20line%20is%20falling%7D%5C%5C%5C%5Cc.%5C%20m%3D0%2C%5C%20%5Ctext%7Bthe%20line%20is%20horizontal%7D%5C%5C%5C%5Cd.%5C%20m%5C%20is%5C%20unde%20fined%2C%5C%20%5Ctext%7Bthe%20line%20is%20vertical%7D)
Step-by-step explanation:
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
If
m > 0, then a line is rising
m < 0, then a line is falling
m = 0, then a line is horizontal
m is undefined, then a line is vertical

No shel will not have enough tile. If you don't know the dimensions of the actual tile how will you solve. If you have a closet 18 square feet it could be 9 ' x 2 ' = 18 square feet. If the tiles were 12" x 6" you would need 36 tiles. If the closet was 6' x 3' = 18 square feet you could have the tiles 12" x 6" = 36 tiles. So you need to know the dimensions of the tile.
Let G be the granola we need (in pound)
Let N be the nut we need (in pound)
Trail mix cost $5.00 per pound---> cost for 7 pound = 5 x 7 = $ 35
4.5G+7N= 35
G+ N = 7
Therefore G = 5.6 N=1.4, we would need 5.6 pound granola & 1.4 pound nut
