52 cards     

     13 clubs (one is an Ace)  3 more Aces = 16 possibles         16/52 = 4/13

2u       u  cannot equal or be less than - 1/2   because    2(-1/2) = -1

-20 u   u cannot equal or be MORE  than   1/20  because  -20 ( 1/10) = -1

[-1/2, 1 /20]     edited    sorry for the math error

a = 14-b

b^3 + (14-b)^3 = b^3+      (196 -28b+b^2)(14-b) =

       b^3 +       2744-196b-392b+ 28b^2 +14b^2 -b^3 = 812

      42b^2 -588b +1932 = 0            Quadratic Formula      a and b = 7+- sqrt 3          or    b = 5.268   a=8.732

                                                                                                                                            b= 8.732   a = 5.268

arctan 1/2   + arctan 1/3   = 45 degrees

The vertical position is given by

yf = yo + vot - 1/2 a t^2        yo = 3   vo = 70 sin 30 = 35 f/s   a = -32.174 ft/s^2

when the ball hits the ground yf= 0    so you have

0 = 3 + 35 t  - 1/2 (32.174)t^2      solve to find t

the x component of the velocity is  70 cos 30 = 60.62 f/s

   use the 't' you found above to find the x distance =  60.62 * t

2u       u  cannot equal or be less than - 1/2   because    2(-1/2) = -1

-20 u   u cannot equal or be MORE  than   1/20  because  -20 ( 1/10) = -1

maybe 39?      3*9  + 3+9 =  27 +12 = 39

9

(363-15)/6  + 1  = ............

3 drinks    3 pieces   20 dollars

[$20- (3 pieces * $3 )-5]  = PRICE OF 3 DRINKS

I'll start you off

there are 360 degrees in the ENTIRE circle

   if you make 2 comgruent pieces ....the central angles will be    360 / 2

      if you make 3  congruent pieces  ....the central angles will be   360 / 3

You should be able to proceed from here !
