Given two points
and
The distance between them is >>>
![D=\sqrt[]{(y_2-y_1)^2+(x_2-x_1)^2}](https://tex.z-dn.net/?f=D%3D%5Csqrt%5B%5D%7B%28y_2-y_1%29%5E2%2B%28x_2-x_1%29%5E2%7D)

Answer: 211 miles
Step-by-step explanation: An equation for this could be:
base fee + additional charge (miles driven) = total charge
19.99 + 0.86(x) = 201.45
0.86(x) = 201.45 - 19.99
0.86(x) = 181.46
x = 
= <em>211 miles</em>
Answer:
1. 3/4, 0.75, 75%
2. 1/4, 0.25, 25%
3. 3/5, 0.6, 60%
4. 5/5, 1, 100%
5. 1/2, 0.5, 50%
6. 4/6, 0.6, 66.6%
Step-by-step explanation:
It’s A) 9.1 because it equals 82.81 while answer B) 9.2 equals 84.64.
Add another triangle to make it a square/rectangle. Then find the perimeter of that. Then divide the answer by 2. That will be the perimeter of the shape.
