PLEASE SHOW ALL YOUR CALCULATIONS
10. You are the
veterinarian at a zoo that has 21 zebras. Each zebra needs to get
four
intravenous shots (over the course of a month) of a vaccination
against Zebra Zombie Disease.
Each injection contains 750 mg of the active vaccination agent. How
many grams of the active
vaccination agent should you order for the month?
12. A municipal
transit system has 85 diesel buses that travel an average of 47,000
miles per
year each. Because of the start and stop nature of a bus route,
they only get an average of 5
MPG. If diesel costs $2.75 per gallon, how much is the annual fuel
bill?
13. A block of metal is 5 cm by 7 cm by 9 cm and has a mass of 854
grams. Calculate the density
of the block and give your best guess of what it is made of.
Express the density in both g/cm3
and kg/m3.
14. You have a 100-watt light bulb on your front porch that is
turned on 10 hours every night. If
the cost of electricity is 12 cents per KWHR (kilowatt hour), how
much does that bulb add to
your monthly electric bill?
15. The parking lot of a college campus has 200 lamp posts. Each
lamp post has two 1200-watt
light bulbs. The lights are on an average of 10 hours per night
year-round. Calculate the annual
electric cost for the lights if the college pays 8.5 cents per
KWHR.
