There are six equally spaced beads on a circle How many straight lines are needed to connect each bead with every other bead?

15. The fisr bead needs 5 lines to connect to the others; the second four (one has already been drawn); the third three, the fourth two, the fifth one; the sixth then already connects to the rest. For n beads, the general answer is: n x (n-1) / 2.


There are four equally spaced beads on a circle. How many straight lines are needed to connect each bead with every other bead?

The first bead needs three lines to connect it to every other bead.The second bead needs two more lines to connect it to every other bead (it's already connected to bead 1).The third bead needs one line to connect it to bead 4 (it's already connected to 1 and 2).The fourth bead is already connected to all the other beads, so no additional lines are needed.That's six lines total.

What is the shortest distance between 2 places on the globe?

a straight line ^Wrong. A straight line is NOT the shortest distance between two places when you're on a globe. http://en.wikipedia.org/wiki/Great_circle This is mathematically proven using calculus. Another way to prove this is to take a globe, and get some string. Pick two points, and make a straight line with the string to measure the distance. Cut off the extra string so you are using the exact amount needed for a straight line. Now, use the great circle, and you will be able to reach the same point, and have extra string left over, proving that the great circle is shorter than the straight line.
