Every sheet in March 1971
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st March 1971y is directly proportional to sqrt(x). When x = 16, y = 24. Work out y when x = 36.
- 2nd March 1971A cuboid measures 11 cm by 7 cm by 7 cm. Work out the length of the longest diagonal inside it, to 1 decimal place.
- 3rd March 1971A bag holds 5 red and 3 blue counters. Two are taken without replacement. Given the first was red, what is the probability the second is blue?

- 5th March 1971Rationalise the denominator of 42/sqrt(7), giving your answer in its simplest form.
- 6th March 1971Prove that the sum of 3 consecutive integers is always a multiple of 3. State the simplified sum you would use.
- 7th March 1971A train slows steadily from 33 m/s to rest in 5 seconds. Work out its deceleration.
- 8th March 1971A cuboid measures 12 cm by 10 cm by 5 cm tall. Work out the angle between its longest internal diagonal and the base, to 1 decimal place.
- 9th March 1971A bag holds 7 red, 3 blue and 4 green counters. Two are taken without replacement. Given neither is green, what is the probability both are red?
- 10th March 1971A histogram has two bars: one 5 units wide with frequency density 2, one 5 units wide with density 3.5. How many values in total?
- 11th March 1971Simplify sqrt(50) + sqrt(8), giving your answer in the form a sqrt(b).
