Answer:
175
Step-by-step explanation:
It is much easier if you use the unit rate, so we'll convert the first senta\ence into a ratio. 2 cubic feet:90lb. you need to get 1 cubic foot, so divide both sides my 2, 1 cubic foot:35 pounds. now, to get five cubic pounds(See where this is going?) you multiply both sides by 5. 5 cubic feet:175lb
(these idoits make you go back and forth in solving problems)
Answer:
F(0) = 0
F(1) = 3
F(2) = 2 x F(1) + F(0) = 2 x 3 + 0 = 6
F(3) = 3 x F(2) + F(1) = 3 x 6 + 3 = 21
F(4) = 4 x F(3) + F(2) = 4 x 21 + 6 =90
F(5) = 5 x F(4) + F(3) = 5 x 90 + 21 = 471
Hope this helps!
