Answer:
101º
Step-by-step explanation:
supplementary angles mean they equal 180
so 180 - 79=101
$0.50/ (1/4 pound)= $2.00/pound.
The final answer is $2.00 per pound~
Answer:
The slope of the following graph is:
![m=3](https://tex.z-dn.net/?f=m%3D3)
Step-by-step explanation:
Given the line on the graph
Taking two points
Finding the slope between the points (40, 20) and (50, 50)
![\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cmathrm%7BSlope%7D%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
![\left(x_1,\:y_1\right)=\left(40,\:20\right),\:\left(x_2,\:y_2\right)=\left(50,\:50\right)](https://tex.z-dn.net/?f=%5Cleft%28x_1%2C%5C%3Ay_1%5Cright%29%3D%5Cleft%2840%2C%5C%3A20%5Cright%29%2C%5C%3A%5Cleft%28x_2%2C%5C%3Ay_2%5Cright%29%3D%5Cleft%2850%2C%5C%3A50%5Cright%29)
![m=\frac{50-20}{50-40}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B50-20%7D%7B50-40%7D)
![m=3](https://tex.z-dn.net/?f=m%3D3)
Thus, the slope of the following graph is:
![m=3](https://tex.z-dn.net/?f=m%3D3)
