Wayne's class is building a wagon to be used as a float for the upcoming Pioneers Day Parade. The outsides of the four wagon wheels are going to be covered in brown felt so they can draw pictures on them. Rubber stripping will go around the wheel to help give it a smoother ride during the parade.
If each wheel has about 94.2 inches of rubber around it, the diameter of each wheel is
inches.
Given this diameter, they need
square inches of felt to cover each wheel.
If they can buy a rectangular piece of felt that has a width equal to the diameter of the wheel, the rectangular piece of felt would need to have a length of at least
inches in order for each of the four wheel covers to be a solid piece. Though to account for any cutting errors, it should probably be a little longer.

Exercise: counting committees 0.0/2.0 puntos (calificable) we start with a pool of n people. a chaired committee consists of k≥1 members, out of whom one member is designated as the chairperson. the expression k(nk) can be interpreted as the number of possible chaired committees with k members. this is because we have (nk) choices for the k members, and once the members are chosen, there are then k choices for the chairperson. thus, c=∑k=1nk(nk) is the total number of possible chaired committees of any size. find the value of c (as a function of n ) by thinking about a different way of forming a chaired committee: first choose the chairperson, then choose the other members of the committee. the answer is of the form c=(α+nβ)2γn+δ. what are the values of α , β , γ , and δ ?
