    Venn Problem

    the answer is 66: 33=x+16+8+5 43=y+16+18+5 42=z+18+8+5 x=4, y=4, z=11 Total = (sum of exactly 1 ) + (sum of any 2) + (all 3)=4+4+11+16+18+8+5=66
  2. 1.a. (216/54)^1.5=8 1.b. surface=2*pi*r^2+2*pi*r*h 2. y=-3x/5+3
  3. 9\3*12\3*round(8\3)=3*4*2=24

    (25..45)4=(45..60)2 100..180=90..120 So, it should be between 100 and 120.
