Transcript of "Mathematical Literacy 4 Module 2 Part 2"

  1. 1. 2. IDENTIFY AND USE INFORMATION FROM DIFFERENT REPRESENTATIONS OF RELATIONSHIPS TO SOLVE PROBLEMS IN THE WORKPLACE <ul><li>At the end of this outcome, you will be able to: </li></ul><ul><ul><li>Identify and select information from different representations of relationships to solve problems </li></ul></ul><ul><ul><li>Use and develop formulae with confidence </li></ul></ul>
  2. 2. Activity 10 <ul><li>Solve the following equations by logic: </li></ul><ul><li>14t =28 What is the value of t </li></ul><ul><li>x / 1000 = 56 What is the value of x </li></ul><ul><li>V = (28)(160)(17) What does V stand for and what is its value? </li></ul><ul><li>6500 = (8)(25)(h) What does the “h” stand for and what is its value? </li></ul>2 56 000 Volume 76 160 units 3 Height 32.5 units
  3. 3. Activity 11 <ul><li>Select the correct formula from the given table and then calculate the unknown value by using the given substitution values. </li></ul><ul><li>a. SI if P=R20 000; t = 10 years and r =15% </li></ul><ul><li>b. S if d = 42.2km at t=2hrs25min </li></ul><ul><li>c. Volume of a tank if r of the base = 2.5m and the height of cylinder =9.25m </li></ul>SI = R30 000 S = 17, 46 km.h -1 181.62m 3
