4) Tammy is preparing to display all her rocks on a 28 inch by 22 inch poster board. Each rock
will be in its own square with side length 3 and 1/4 inches, which fits her largest rock. The
maximum number of squares that fit on the poster board is the same as the number of rocks in
her collection. How big is her collection? |
5) Roni loves to talk. Roni's mom is a tech wiz and programs Roni's phone so that after 7pm,
each time she is on her phone it cuts her off at half of the time she spent on her previous
conversation. Her first phone call lasts 52 minutes and starts at 7:05 pm. If she talks until she is
cut off in every conversation after that, how many minutes has she been on the phone at the end
of her sixth call? Express your answer as a mixed number.
