Every sheet in September 1971

The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.

  1. 1st September 1971A rectangle is 27 cm by 20 cm, each correct to the nearest cm. Work out the upper bound of its area.
  2. 2nd September 1971Solve x^2 + y^2 = 169 and y = x + 7 simultaneously.
  3. 3rd September 1971y is directly proportional to x^3. When x = 4, y = 192. Work out y when x = 2.
  4. 4th September 1971A cuboid measures 12 cm by 12 cm by 8 cm tall. Work out the angle between its longest internal diagonal and the base, to 1 decimal place.
  5. 5th September 1971A bag holds 5 red, 6 blue and 2 green counters. Two are taken without replacement. Given neither is green, what is the probability both are red?
  6. 6th September 1971A histogram has two bars: one 20 units wide with frequency density 2, one 20 units wide with density 1.4. How many values in total?
  7. 7th September 1971Expand and simplify (7 + sqrt(7))(7 - sqrt(7)).
  8. 8th September 1971Use the iteration x(n+1) = cube root of (7x(n) + 3) with x(0) = 5. Work out x(1) to 3 decimal places.
  9. 9th September 1971y is directly proportional to sqrt(x). When x = 36, y = 24. Work out y when x = 25.
  10. 10th September 1971The point (12, 16) lies on the circle x^2 + y^2 = 400. Work out the gradient of the tangent to the circle at that point.
  11. 11th September 1971A bag holds 5 counters, r of them red. Two are taken without replacement and P(both red) = 1/10. Work out r.
