Answer:
2.0 , 2/1.
1.35 , 1 7/20.
1.52, 1 13/25
0.0003, 3/10000
0.0045, 9/2000
Step-by-step explanation:
1.35 = 1 35/100 = 1 7/20
1.52 = 1 52/100 = 1 13/25
0.0045 = 45/10000 = 1 9/2000.
Answer: 4
The distance between two points is measured by distance formula of coordinate system.
Step-by-step explanation:
Distance formula :
If two points L and M are given having coordinates L(x1, y1) and M(x2, y2), then the distance between these two points is D=
(x2-x1)² + (y2-y1)²
So the distance between the points (3, 3) and (7, 3) is
D=
(7-3)² + (3-3)² =
16 = 4
Distance between the two points is 4
