Suppose you work for a large coffee distributor that has a secret coffee blend it sells to local stores. You mix the Rift Valley blend with the Arabian Mocha blend, but always in the same proportion. Yesterday, you mixed 90 pounds of the Rift Valley blend with 27 pounds of the Arabian Mocha blend. Today, there is 60 pounds of the Rift Valley coffee left in stock. How many pounds of the Arabian Mocha coffee should you mix with it to get your secret blend?

Suppose you have a cube of length s. The volume of that cube is V = s^3. Now let's suppose the dimensions of that cube (and hence its volume) depend on time. We are wondering about the relationship between the growth of the length versus the growth of the volume. Supposes(t) = t.Then s'(t) = t______________ and V'(t) = t ___________Next suppose V(t) = t. s'(t) = t______________ and V'(t) = t____________

An oil refinery is located 1 km north of the north bank of a straight river that is 3 km wide. A pipeline is to be constructed from the refinery to storage tanks located on the south bank of the river 5 km east of the refinery. The cost of laying pipe is $200,000/km over land to a point P on the north bank and $400,000/km under the river to the tanks. To minimize the cost of the pipeline, how far downriver from the refinery should the point P be located?

A recording company obtains the blank CDs used to produce its labels from three compact disk manufacturers: I, II, and III. The quality control department of the company has determined that 1% of the compact disks produced by manufacturer I are defective, 7% of those produced by manufacturer II are defective, and 3% of those produced by manufacturer III are defective. Manufacturers I, II, and III supply 36%, 20%, and 44%, respectively, of the compact disks used by the company. What is the probability that a randomly selected label produced by the company will contain a defective compact disk?
