24 different ways.
24
That would be 5x4x3x2x1 or 5! or 120 ways to arrange those objects in a line.
They could be the coordinates of a straight line equation
The line that forms the apparent boundary between earth and sky.
draw 9 lines and join them
24: The first picture can be any of 4, the second any of the remaining 3 etc so 4 x 3 x 2
draw two triangles with overlapping lines
as long as it is not installed on a drain line. If it is used strictly on the vent system then yes it can be used horizonally.
Mathematically speaking, if you line them up in one straight line, there are 5040 ways. You do 7*6*5*4*3*2*1=5040. The * means multiply.
There are 1680 ways of arranging them is a straight line: fewer if in a circle.
To place 10 coins in 5 straight lines with 4 coins on each line, you can arrange them in a pattern where each line intersects with the others. One way to achieve this is by placing 4 coins in a square formation, then placing 3 coins in a straight line across the middle of the square, and finally placing the last 3 coins in a straight line perpendicular to the middle line. This arrangement creates 5 straight lines, each containing 4 coins.
Yes. If it is not straight, then it is not a line.
