a 500-foot roll of fencing will be used to enclose a rectangular play pen for pets.
which equation could not be used to find the possible length, 1, and width, w, of the
play pen?
a. 500 = 2lw
500 = 1 + w
c. 2(1 + w) = 500
500 = 21 +2w

Consider the reaction 2x2y2+z2⇌2x2y2z which has a rate law of rate= k[x2y2][z2] select a possible mechanism for the reaction.

Saline iv fluid bags cost $64.20 for 24, 1000 ml bags from one supplier. a new supplier sells 500 ml bags for $2 each. the hospital uses about 10,000, 1000 ml bags each month. nurses report that about half of the bags are more than half full when they are discarded. if you are going to use only one supplier, which size bag provides the best deal, and how much will you save each month? compare the cost of the new supplier to the current one.
