28. Switch everything to eights:
[tex] ( \frac{1}{8}) +4( \frac{4}{8} )+( \frac{5}{8} )+2( \frac{6}{8} )+( \frac{7}{8)} )= \frac{41}{8} [/tex] this represents the sum of the pieces shown on the graph.
Now we add the 1 foot left over: [tex] \frac{41}{8} + \frac{8}{8} = \frac{49}{8} =6 \frac{1}{8} [/tex]
29.Answer is choiice D.. [tex] \frac{3}{3} =1 [/tex] and 1 x 12 = 12 so any number for 'k' greater than 3 will create a factor greater than '1' to be multiplied by 12 resulting in a product greater than 12.
