: : : : a rectangle has a length of 100 inches and a width of 50 inches. There will be a bolt at each corner and then a bolt spaced every ten inches in both of the 100 inch sides. How many bolts will there be total?
: : What it is? A joke?
: : 22
: No, not a joke . A legitimate question. I'm looking for methods used out there to solve it aside from drawing and taking physical measurement. Could you elaborate a little on how you arrived at the answer? Thank you, tom
Well. To get one segment of the line you need to have two points. To cover two segments you need three points and so on. To cover N segments you need N+1 points, right? Only what you have to do figure out how many segments you have
In this particular case all your segments are equal 10". N = 100" : 10" = 10 N+1 = 10 + 1 = 11
For two side 11 * 2 = 22
That is it.
