I think the answer is 75.6 because i divided 36 cards by 5 folders and i got 1.2. And then i divided 372 extra cards by 5 folders am got 74.4. I add the two total and have 75.6
5/36 = 1.2 5/372 = 74.4
1.2+74.4= 75.6 srry if I'm wrong
Given:
M=(x1, y1)=(-2,-1),
N=(x2, y2)=(3,1),
M'=(x3, y3)= (0,2),
N'=(x4, y4)=(5, 4).
We can prove MN and M'N' have the same length by proving that the points form the vertices of a parallelogram.
For a parallelogram, opposite sides are equal
If we prove that the quadrilateral MNN'M' forms a parallellogram, then MN and M'N' will be the oppposite sides. So, we can prove that MN=M'N'.
To prove MNN'M' is a parallelogram, we have to first prove that two pairs of opposite sides are parallel,
Slope of MN= Slope of M'N'.
Slope of MM'=NN'.

Hence, slope of MN=Slope of M'N' and therefore, MN parallel to M'N'

Hence, slope of MM'=Slope of NN' nd therefore, MM' parallel to NN'.
Since both pairs of opposite sides of MNN'M' are parallel, MM'N'N is a parallelogram.
Since the opposite sides are of equal length in a parallelogram, it is proved that segments MN and M'N' have the same length.
The distance between the two points is 
The polar coordinate of A is 
The polar coordinate of B is 
Explanation:
The two points are
and 
The distance between two points is given by,

Thus, the distance between the two points is 
The polar coordinates of A can be written as 
Distance = 
Substituting
, we get,
Distance = 

To make the angle positive, let us add 360,

The polar coordinate of A is 
Similarly, The polar coordinate of B can be written as 
Distance = 
Substituting
, we get,
Distance = 

To make the angle positive, let us add 360,

The polar coordinate of B is 
2/9 ÷ 4/1 (keep,change,flip) is 1/18.
