loris [4]
The line would start at the bottom of the distance versus time graph and start to move up at a constant speed (straight diagonal line) for 4 minutes then there would be a straight horizontal line representing the time she was not moving, so 3 minutes. Then another straight diagonal line representing her walking for 2 minutes after talking to Maria.

Well, we have to determinate the 65% of 140, which are 91 members play soccer. 

The total members are 140, if 91 play soccer, 49 members do not play soccer. 

The answer is 49 members.

Serial numbers for a product are to be made using 2 letters followed by 2 digits. The letters are to be taken from the first 6 l

Alright so I'm coming up with this on the fly; you have the first six letters (a,b,c,d,e,f) and 0-9 and your ten numbers. calculate the amount of possible combinations for the letters by simply writing them down.
ab, ac, ad, ae, a f- five
bc, bd , be, bf- four
cd, ce, cf- three
de, df- two
ef,- one.
adding these all together gets a total of 15 for the letters. now the numbers
01, 02, 03, 04, 05, 06, 07, 08, 09- nine
12, 13, 14, 15, 16, 17, 18, 19- eight
23, 24, 25, 26, 27, 28, 29- seven
34, 35, 36, 37, 38, 39- six
45, 46, 47, 48, 49- five
56, 57, 58, 59- four
67, 68, 69- three
78, 79- two
89- one
added together with a total of 45 combinations.
alright so, 45 different number combinations and 15 letter combinations. multiplying 15 by 45 should tell you the total possible combinations for a two letter and two number serial-number
