## End of year B

These two sheets are equivalent, the sets of ten questions swapped so that 11-20 come first on this one (because so many pupils failed to finish).

11.Solve these:

5x – 3 = 10 – 2x;
2(x + 5) = 7 – x;
4x + 5 = 9x – 6

12. These are the first few terms of a sequence: 9, 13, 17, 21, 25, ...

Write down a rule for the next term

Find a formula for the nth term

Find the 100th term

Find the formula for the sequence which starts 25, 21, 17, 13, 9, ...

What is the 100th term of this second series?

13. Write these numbers,           57903,         179939,                7932,

to the nearest ten;   to the nearest hundred;      to two significant figures in standard form

14. Fred wants more than 70% in the next test. There are 60 questions, 60 marks. How many must he get right?

15. To convert Centigrade to Fahrenheit you must multiply by 9, divide by 5 and add 32.

Convert  (i)     5ºC to ºF                             (ii)    100ºC to ºF

(iii)       Find what  -40º F is in ºC

16. Write these in order, smallest first:    4/3,  0.785,  √2,  0.950,   6/7

17. There are three otherwise identical cars of different colours. How many different ways can they be parked in three adjacent spaces and facing the same way?

4. (a) Write the prime factors of 84.         (b) Find the highest common factor of 84 and 56. (c) Find the lowest common multiple of 84 and 56. [no calculator!!]

5. Draw the triangle ABC with vertices (1, 2), (3, 2) and (3, 5).    –3<x<10, -4<y<10

(a) Reflect ABC in the line x=5            (b) Rotate ABC about (1,1) through 90º clockwise

6. Indicate the number of lines of symmetry and order of rotational symmetry for each of:

(a) a rhombus     (b) an ellipse      (c) a parallelogram      (d) a kite.

7. Draw accurately a triangle with angles of 60º and 55º and a side of 11cm between them. Use a protractor.

Bisect the new angle using compasses.

Measure the shortest side to the nearest millimetre.

8. A car hire company uses the formula y = 30x + 12 to work out the cost £y of hiring a car for x complete days. Find the cost of hiring a car for 1, 5 and 10 days. Draw the graph of y = 3x + 12. Use 0<x<10 and 0<y<100 (one unit per square in x, ten in y).
