2) Every pyramid is a polyhedron
3) The bases of all cones are circles
4) All lateral faces of an oblique prism are rectangular regions

All I have to know is true/false but if you have time to explain, I would appreciate it to help me better understand.

An exam question is showing an experiment to prove snails produce carbon dioxide. It then asks how you can modify the experiment to prove plants produce carbon dioxide during repiration. I can only think of putting the plant in the dark and testing the gas. But how would you test it. Lighted splint going out is not conclusive enough and would there be enough carbon dioxide anyway. Thanks

Three buisness women need to rent a car for a day. the cost is $30 so they each pay$10. as they approach their rental car, the owner at the counter says "wait theres been a change. its your lucky day. the fee is only $25. heres $5 back." since the women are in a hurry and do not want to split the $5 they give the owner a $2 tip and they keep $3. so each women paid $10-$1 (money they each got back) = $9, times 3 is $27. If you add the $2 tip u get $29!!! wheres the extra dollar?
