0 bonanova Posted May 12, 2015 Report Share Posted May 12, 2015 No Let f = GCD (A, B) so that A = f a and B = f b where GCD (a, b) = 1. Then (A+B) = f (a+b). GCD (A+B, A) = f GCD (a+b, a) = f = f GCD (a+b, b) = GCD (A+B, B) = GCD (A, B). Approximately,R ~ 4000 mi; land area ~ (3/10)(4) pi R^{2} sq miles; 3' of snow ~ 3" of water = 3/(12x5280) miles of water. Do the math: (land area) x (water depth) cubic miles of water would be needed.. It depends. A) if "on a globe" refers just to the points then the distance between them is the length of a straight line; B) if "on a globe" refers to the distance then the distance on the globe's surface is the length of a curved line. The speed of light. Quote Link to comment Share on other sites More sharing options...

## Question

## phil1882

1. if all borks are grogs, and all grogs are snorts, are all snorts borks?

2. prove that GCD(A,B) = GCD(A+B,A) = GCD(A+B,B)

3. how much water, approximately, would you need to cover all land on earth in 3 feet of snow?

4. whats the shortest distance between any two points on a globe? A) straight line B) curved line

5. and just to be silly: what's the speed of dark?
