This test has 6 pages. Maximum number of points is 32. Calculators allowed:
any calculator, no restrictions.
If some piece of information is missing, you must decide on its value.
1. Circle ONE answer, or FILL IN THE BLANK. No justification is needed.
(a)[2] Which of the following numbers is the largest, when converted to a decimal number?
(A) (6000)8
(B) (6; 0; 0; 0)20
(C) (6000)12
(D) (6000)16
(b)[2] You are counting in the vigesimal system (base 20), starting from (18; 19; 19)20. What
is the next number?
(A) (19, 19, 19)20
(B) (19; 0; 0)20
(C) (18; 19; 0)20
(D) (1; 0; 0; 0)20
(c)[2] The average growth rate of human hair is about 1.2 centimetres per month. The
average rate of growth of human nails is about 0.1 millimetres per day. (These are averages;
actual growth rates depend upon age, gender, season, exercise level, diet, and hereditary
factors.) Based on this information, circle the correct conclusion.
(A) Human hair grows faster than human nails.
(B) Human hair grows slower than human nails.
