If the scale is
R.F.= 1/2000000
=1/2x 10000x100
1cm=20000m
The scale of a map is given as= 1/2000000
Two town are 4 cm apart on the map.
the actual distance between two towns
=4x 20000
=80000 m
=80000/1000 Km
=80Km
I hope this help you

Step-by-step explanation:
C
Answer:
Four unique planes
Step-by-step explanation:
Given that the points are non co-planar, triangular planes can be formed by the joining of three points
The points will therefore appear to be at the corners of a triangular pyramid or tetrahedron such that together the four points will form a three dimensional figure bounded by triangular planes
The number of triangular planes that can therefore be formed is given by the combination of four objects taking three at a time as follows;
₄C₃ = 4!/(3!×(4-3)! = 4
Which gives four possible unique planes.
The answer is negative -2 so im going to go with D
