ANSWERS

  1. 10/0.834  − 3/129.64 
    (10 x 1.199) − (3 x 0.007713)
    11.99 − 0.923139
    11.966861
    12.0
  2. 807 → 0.001239
    0.0591 → 16.92
    5(0.001239) + 4(16.92)
    = 67.69
  3. ¹/³ {2 x 1.5065 + 5 x 1.2004}
    ¹/³ (3.013 + 6.002) (0.3333)
    = 9.015 x 0.3333
    = 3.005 (3 dp)
  4.  
    R A5
  5. 4/(8.68)³ + 5/34.46 
    4/653.97 + (0.1451)¹/³
    4(0.1529) + 0.5255
    0.6116 + 0.5255 = 1.1371
  6. 1/a = 0.007874 + 0.0869
    = 0.9483
    a = 10.55

  7. R A8
    √3.87946 = √3.879
    = 1.9695
    = 1.970(4s.f)

  8. R A9
  9. 3x1.485 + 13x6.410
    = 4.455 + 83.33
    = 87.785

    ALT
    30/6.735 + 130/1.56 = 30 x 0.1485 + 130x0.641
    = 4.455 + 83.33
    = 87.785
