What else can I help you with?
If there are 8 people at a party and every person shakes hands with everyone else at the party how many handshakes will there be?
There will be 28 handshakes. If you ask each person how many handshakes they had they will tell you 7 making 7 x 8 = 56 handshakes in all. But every hand involves two people, so every handshake has been counted twice, thus there are 56 / 2 = 28 handshakes in all.
If there were 28 handshakes how many people?
8
At certain party there wereb 45 handshakes Everyone shook hands with everyone else exactly once how many people attended the party?
There were ten people at the party. This is a triangular sequence starting with two people: 1, 3, 6, 10, 15, 21, 28, 36, 45, etc. There's an equation for this. With n people at the party, the number of handshakes is n(n-1)/2.
How many 2 person conversations are possible at a party of 28 people?
28*27/2 = 378
There are 8 people at a party each person shakes hands with everybody else once how many handshakes are there?
28. The formula is (n * (n-1)) / 2, where n represents the number of people. You divde by 2 because each handshake covers two possibilities (ie, person #1 to person #8 is the same as person #8 to person #1).

If twenty nine people in a room shake hands how many handshakes would there be?
1/2 of (29 x 28) = 29 x 14 = 406
At a party 28 handshakes were exchanged How many people were present at the party?
The underlying assumption is that each person shakes the hand of each other person. If there are "n" people, each will shake the hands of "n-1" other people. To avoid counting double, the result has to be divided by 2. Therefor, the number of handshakes is equal to n(n-1)/2. Trying this out for several values of "n" should be faster than using the quadratic formula. (If you use the quadratic formula, you will probably get a positive and a negative solution - you can discard the negative solution.)

If you have 28 hand shakes how many people in the room?
i dont know there could be other peolple in the room besides the people doing hand shakes but if there werent, and there were only two people to each hand shake, there would be 56 people in the room.
