  1. Revision

  2. 1. Factorise 7d – dh 2. Percy gets £8 per hour and works 32 hours per week. a) Calculate weekly wage. b) Overtime rate is time and a half. How much will he get if he works 38 hours?

  3. E 3. In triangle below LDEF is 900 Calculate length of DE (to 1 d.p.) 4cm D F 14cm

  4. 4. In a raffle where 400 tickets have been sold, Harriet calculates that the probability of her winning is 0.3. How many tickets has she? 5. Tony has £94 to spend. By the end of the day, he has £13 left. What percentage of his money did he spend?

  5. 1. Factorise 7d – dh d( 7 – h)

  6. 2. Percy gets £8 per hour and works 32 hours per week. a) Calculate weekly wage. 8 X 32 = 256 b) Overtime rate is time and a half. How much will he get if he works 38 hours? Overtime rate = 1½ X 8 = £12 per hour Hours of overtime = 6 Overtime pay = 6 X 12 = £72 Total Wages = 256 + 72 = £328

  7. E 3. In triangle below LDEF is 900 Calculate length of DE (to 1 d.p.) x2 = 142 – 42 = 180 x = √180 = 13.4 4cm D F 14cm

  8. 4. In a raffle where 400 tickets have been sold, Harriet calculates that the probability of her winning is 0.3. How many tickets has she? Prob. = Tickets Tickets ÷ 400 = 0.3 Tickets = 0.3 X 400 = 120 = 0.3 400

  9. 5. Tony has £94 to spend. By the end of the day, he has £13 left. What percentage of his money did he spend? Money spent = £81 81/94 = 86.2%
