Keeping in mind what you did in the lab this week, do you think that determining the volumes of your solid samples (rubber stopper, crock stopper, and pennies) by measuring their dimensions and calculating it mathematically would be more or less accurate than determining their volumes by water displacement? Explain.

You are thinking of making your mansion more energy efficient by replacing some of the light bulbs with compact fluorescent bulbs, and insulating part or all of your exterior walls. each compact fluorescent light bulb costs $4 and saves you an average of $2 per year in energy costs, and each square foot of wall insulation costs $1 and saves you an average of $0.20 per year in energy costs.† your mansion has 150 light fittings and 3000 sq ft of uninsulated exterior wall. to impress your friends, you would like to spend as much as possible, but save no more than $750 per year in energy costs (you are proud of your large utility bills). how many compact fluorescent light bulbs and how many square feet of insulation should you purchase? how much will you save in energy costs per year? (if an answer does not exist, enter dne.)

Two products, qi and vh, emerge from a joint process. product qi has been allocated $34,300 of the total joint costs of $55,000. a total of 2,900 units of product qi are produced from the joint process. product qi can be sold at the split-off point for $11 per unit, or it can be processed further for an additional total cost of $10,900 and then sold for $13 per unit. if product qi is processed further and sold, what would be the financial advantage (disadvantage) for the company compared with sale in its unprocessed form directly after the split-off point?
