Any 2 points determine a line. if there are 6 points in a plane, no 3 of which lie on the same line, how many lines are determined by pairs of these 6 points?

Total number of lines formed by 6 points will be 15.

Step-by-step explanation:

Number of lines determined by 2 points = 1

There is a condition that only 2 points lie on a line.

Total number of points on a plane = 6

We have to calculate the number of lines formed by the pairs of these 6 points.

It's a question of combinations.

Number of combinations formed =

=

=

=

= 15

Therefore, total number of lines formed by 6 points will be 15.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
