♦ The boiling point of water is 100ºC. You have a tank that has a temperature control
in degrees Fahrenheit. What must you set the temperature to in order to boil the water
in the tank?
♦ Danny is an operator at a bottling plant. Each bottle has a volume of 500 ml. He is
given an export order to the USA for 400 gallons of vinegar.
i) How many bottles must he fill?
ii) Danny's colleague checks his calculations, but he rounds off the conversion rate to 3,8 litres. How many extra bottles would he have filled?
iii) The sales manager who took the order has rounded off the conversion rate to the nearest litre. How many bottles has he quoted for?
100 C = 212 F (formula F = 9/5 C + 32 )
500 ml = .132086 gal
400 / .132086 = 3 028 bottles
400 * 3.8 * 2 = 3040 12 extra bottles
400*4 *2 = 3200 bottles
