QUESTION 4

In South Africa there are ordinary schools and special schools. Special schools are for learners with special needs. Ordinary schools are divided into public schools and independent schools.

mathlitp243

The government generally funds ordinary schools, and some schools levy school fees.

In February 2015 a newspaper published data relating to the number of learners, teachers and schools per province in South Africa. Refer to TABLE 4 and TABLE 5 in ANNEXURED

TABLE 4 shows data from 2014 relating to the number of learners, teachers and schools in the ordinary school sector per province.

TABLE 5 shows data from 2012 to 2014 relating to the number of learners and teachers in the ordinary school sector per province.

4.1.4 After reading the data in TABLE 4, a teacher stated:

'In South Africa, the teacher-to-learner ratio of independent schools is better than that of public schools.'

Verify, showing ALL calculations, whether this teacher's statement is valid. (6)

4.3

A company would like to build a three-dimensional (3D) model of a 21" century classroom. This must be a scaled model of an actual classroom that they have built at a school.

The actual dimensions of the classroom are:

length = 7,5 m; width-6,5 m and height = 3 m

The 3D scale model of the classroom must fit on a rectangular table top with the following dimensions:

length = 1,75 m and width - 1 m

Only half of the table top area may be used for the scaled model.


Verify, showing ALL calculations, whether a scale of 1:8 will be suitable for the scaled model. (5)

QUESTION 5

5.1

Mrs Dundee, an Australian farmer, has four silos on her farm in which she stores fertiliser, as shown in the photograph and diagram below. The silos are cylindrical with a roof section. Fertiliser is only stored in the cylindrical part of the silos.

  • Silo 1: 15% full
  • Silo 2: 1/4 full
  • Silos 3 and 4: empty

Verify, showing ALL calculations, whether she will have enough fertiliser left in her silos for the wheat field if the spread rate is 22,65 kg of fertiliser per acre. (6)
