Increase 60 in a ratio of 2:3
60 x 2/3 = 120/3 = 40
60 x 3/2 = 180/2 = 90
2+3 = 5. 60/5 = 12. 2 x 12 = 24. 3 x 12 = 36. Therefore 24:36
60/5 = 12
Jack invests R300 for 5 years at a simple interest rate of 10% p.a. What will his money amount to after 5 years?
A = P(1 + in). A = 300(1 + 0,1 x 5). A = R450
A = P(1 + i x n). 300 = P (1 + 0,1 x 5). P = R200
A = P(1 + i)n. A = 300(1 + 0,1)5. A = R483,15
A = P(1 + i)n. 300 = P(1 + 0,1)5. P = R186,28
Jack takes out a loan of R2000 at an interest rate of 10% compounded annually. How much will he pay back on the loan if he pays it back after 3 years?
A = P(1 + in). A = 2000(1 + 0,1 x 3). A = R2600
A = P(1 + in). 2000 = P(1 + 0,1x3). P = R1538,46
A = P(1 + i)n. A = 2000(1 + 0,1)3. A = R2662
A = P(1 + i)n. 2000 = P(1 + 0,1)3. P = R1502,63

Determine angle SRP
? = 70 (corresponding angles)
? = 60 (alternate angles)
? = 130 (exterior angle of a triangle)
? = 70 (angles opposite equal sides)
Find the length of c
C = 8 + 6. C = 14
C2 = 62 + 82. C2 = √62 + √82. C2 = 6 + 8. C2 = 14. C = √14
C2 = 62 + 82. C2 = 36 + 64. C2 = 100. C = 10
C = 62 + 82. C = 36 + 64. C = 100
