   what is 123456789x8+9=     

   (123456789 x 8) + 9  =     987,654,321     

   123456789 x (8 + 9)  =  2,098,765,413     

   By the products I now know which one you meant.  Neat.     

   Here's one for you.  Notice that you have to omit the 8.     

   12345679 x (2 x 9)  =  222,222,222     

   12345679 x (3 x 9)  =  333,333,333     

   12345679 x (5 x 9)  =  555,555,555     

   12345679 x (7 x 9)  =  777,777,777     

   Try it with the others:  1x9, 4x9, 6x9, 8x9, 9x9

   Lionel deposited $3,631.23 in a savings account that earns 1.9% simple interest. What will Lionel's account balance be in 8 months?     

   3631.23  x  0.019   =      68.99    interest after twelve months     

       68.99  x  ( ⁸/₁₂ )  =      46.00    interest after eight months     

   3631.23  +  46.00   =  3677.23    interest plus principal after eight months

Yes, the answer is 3/2, same for me

The path of B is an arc with radius AB and central angle θ, length 6 = AB * θ (radians).

The path of C is an arc with radius AC and same θ, so length = AC * θ = 6 * (AC / AB).

Ann throws a dice 30 times. The chances of getting 1, 2, 3, 4, 5 or 6 are equal.     

a. How big of a chance is there that her next throw will be a 3?     

b. Ann throws the dice another 12 times. How many times is she expected to throw a 3 on these 12 throws?     

a.  1 / 6    Previouse results have no effect on the probability of the next throw.*     

b.  2 / 6     I think the word "expected" is inappropriate.     

                 Instead, say "the probability" of throwing another 3.     

* You might be tempted to say, "Well, that darn three will never come."     

   Alternatively, "Well, the three hasn't come up,  It's due any time now."     

   These fallacious conclusions are one way casinos make their money.

   A map has a scale 6.5 in=32 miles.  How far apart are two cities that are 97.5  inches apart on the map?     

     32                x     

   –––––   =    –––––     

     6.5             97.5     

    (6.5) x  =  (97.5) (32)     

    (6.5) x  =  3120     

            x  =  3120 / 6.5  =  480

  How do you get 37 only using four 4s? you can only use Square root of four,4!,+-/x,     

             sqrt(4) + 4!     

  37  =  ––––––––––  +  4!     

                sqrt(4)     

                2 + 24     

  37  =  ––––––––––  +  24     

                   2     

                  26     

  37  =  ––––––––––  +  24    =    13 + 24

The answer is 3x^2.

  whats 1 over 2 to the 2nd power     

  two ways to read this:   Either  (1 / 2)²  =  1 / 4     

                                              or   1 / 2²   =  1 / 4     

  They just happen to come out the same     

  because there's a one in the numerator.
