A rectangular solid is 3 cm long 2 cm wide 1 cm mass is 12g What is its density?
What you do find the volume by multiplying the height the width and the length So... 3x2x1=6 Then you divide the mass by the volume m/v= 12 / 6 So... The answer is 2cm3
How many 5 digit combinations can you make with 8 numbers?
WRONG ANSWER NB !!If repeated numbers are permitted the answer is 8x8x8x8x8=32768 (85)If the numbers can only be used once in each combination, the answer is 8x7x6x5x4= 6720, where ABCDE has [n!/ (n-r)!] or [8! / 3!] combinations for 8 numbers used 5 at a time.NONONONO THIS IS NOT THE RIGHT FORMULA IT SHD BE [n ! / (n-r)! x r! ] = ONLY 56 COMBINATIONS where each number can only be used once.8x7x6x5x4x3x2x1 / (3x2x1) ( 5x4x3x2x1) = 56from napoleon solo

How many triangles are formed by the diagonals in a 21 sided polygon?
The number of triangles formed by the diagonals of a 21 sided polygon is C(21,3) = 21x20x19/3x2x1 = 1,330.
How many different ways can you arrange 5 letters in a row?
5 choices for the first, 4 for the second .... so is 5x4x3x2x1 = 120 ways. If 2 of the letters are the same then for any arrangement, switching those 2 doesn't make any difference, so divide the answer by 2. If 3 are the same then there are 3x2x1 ways of shuffling those, which at first were all different arrangements but now are not, so divide by 3x2x1 ie 6.
How many different combinations of 2 dvds are possibles if Amy has 5 dvds?
C 5 2 = 5! / (2! x 3!) = (5x4x3x2x1) / (2x1 x 3x2x1) = 10

How do you find out a permutation?
A permutation is just a way to arrange thing in a certain order. For example, the letters a and b can be permuted as ab and ba. Note there are two letters and 2 permutations. Think of it this way, There are two letters so 2 choices for the first letter and one choice for the second. So 2x1 is 2 If we had a,b and c There would be 3 choices for the first letter, it could be a or b or c, and once one of those is used, two choices for the second and then the last letter is the one left over. So there are 3x2x1=6 permutations. In general if we have n objects, there are nxn-1xn-2....3x2x1 which we write as n!.
