6!  numbers can be made = 720 numbers

Numbers must end in 5 to be a multiple of 5 

  if the number ends in 5 , the first number cannot be a 5    so the only numbers > 500 000 will be the ones that start with a 6

     6 x x x x 5    will all be greater than 500 000  

             for the x's :  4 * 3 * 2 * 1 =   24 numbers out of 720 possible

24/720  <=====  simplify as needed

5 2/3 c flour    *     1/3 c chips / c flour =  5 2/3 * 1/3  c chips =  ................. 

                                                ( see how c flour 'cancels out' and you are left with c chips?)

   root 1     -7 + 2i       means   (x- (-7+2i))   is a factor  of the quadratic:   (x+7-2i)

          2                                    (x- (7 - 2i)    is a factor                               (x - 7+2i)

   ( I suspect the second root should be -7 - 2i)

(x+7-2i)(x-7+2i)      will be your quadratic ....but it will not be of the form    z^2 + bz + c = 0    

    if the second root is   (-2i - 7)    you will get the factor    (x+7+2i)

               then factor1 * factor2    would be      (x+7-2i)(x+7+2i)     and when multiplied out would be of the correct form to calculate b+c.....

I did answer it ....Obviously you would take option 1

Is this question written correctly?    Obviously you would take option 1     option 2 has a smaller and smaller salary everyday.....option 1 has the same salary everyday.

3/8ths are women

x = total number

5/8 x   =   30 + 3/8 x

2/8 x = 30

x = 120 people at wedding                   3/8 * 120 = 45 women

    5/4 = 45/ g       g = girls

     45 * 4/5 = g = 36 girls                      45 women  - 36 girls  = 9   more women than girls at the wedding

The length of one side of a triangle is 3 feet less than twice the length of its second side. The third side is 2/3 of the sum of the lengths of the first 3 sides. Find the length of all  * two *  sides if the perimeter is 6.5

Sides a +b + c = 6.5

a = 2b-3

b

c = 2/3 (b + 2b-3)   

2b-3     +   b    +  2/3 (b   +   2b-3)     = 6.5       first solve for 'b'     then a = 2b-3         etc......

Not a very specific f/u question, Guest !    What is the prob?
