Delbert prepares a 25% glugose solution of by mixing 2 ml of glucose with 8 ml of water. If he adds x ml of glucose to the solution, its concentration is given by C(X)=2+x/8+x
toxicsugar22: How many ml of glucose should delberrt add to increase the concentration to 50%

Best ResponseYou've already chosen the best response.0first find how much glucose it has by setting C(x)=.25\[.25 = {(2+x) \over (8+x)}\] find how much glucose does a 50% concentration solution has by setting the equation equal to 50%:\[.50 = {(2+x) \over (8+x)}\] Last, subtract the 50% x from the 25% x and you will have how much is need to add. is that right?

Best ResponseYou've already chosen the best response.0The cost in thousands of dollers for extracting p% of a precious ore from a mine is given by the equation C(p)=360p/100p Complete this showing the cost of extracting various percents of the ore . if 15 is P then what is C

Best ResponseYou've already chosen the best response.0now you set C(p) = 540,000 so, 540,000 = 360p/100p solve for p

Best ResponseYou've already chosen the best response.0A computer store sells approximately 300 of its most popular model per year. The manager would like to minimize her annual inventory cost by ordering the optimal numbers of computers, x, at regular intervals. If she orders x computers in each shipment, the cost of storage willl be 6x dollers, and the cost of reording will be 300/x (15x+10) dollers. The inventory cost is the sum of the storage cost and the reording cost. use the distributive law to simplfy the expression for the rerding cost. Then express the inventory cost C as a function of x
