Question 12
a) On day 1, one alien virus is placed in an experimental bottle. On day 2 the number doubles; on day 3 it triples; on day 4 it becomes four times the previous day's number. This continues, so on day 10 the number becomes ten times that on day 9. Can the viruses on day 10 be divided equally among 24 test tubes? Explain.
b) A basket contains 13 apples. A scale can measure the combined mass of any two apples. Show how to find the total mass of all 13 apples using eight weighings.
