Worked Solution & Example Answer:A programme inspiring people of all ages and genders usually ends with a fashion show - NSC Mathematical Literacy - Question 4 - 2023 - Paper 2

Step 1

4.1.1 Write, in simplified form, the ratio of the width to the length of the raised runway.

Answer

To determine the ratio of the width to the length of the raised runway, first note that the width is given as 4 feet. From the layout in ANNEXURE B, the length of the raised runway can be assessed. Assuming it is, for instance, 24 feet, the ratio would be calculated as:

extRatio=WidthLength=424=16 ext{Ratio} = \frac{\text{Width}}{\text{Length}} = \frac{4}{24} = \frac{1}{6}

The simplified ratio is therefore 1:6.

Step 2

4.1.2 Convert the length of the floor runway to metres.

Answer

Given the length of the floor runway is 54 feet, we will convert it to metres using the conversion factor:

1extm=3.28084extfeet1 ext{ m} = 3.28084 ext{ feet}

Thus:

Length in metres=543.2808416.46extm\text{Length in metres} = \frac{54}{3.28084} \approx 16.46 ext{ m}

Step 3

4.1.3 (a) Why the second- and third-row seats are not arranged exactly behind the first-row seats that are closest to the floor runway.

Answer

The second and third-row seats are not arranged directly behind the first-row seats to eliminate possible obstructions caused by front row spectators. This design also allows for better visibility for all attendees watching the fashion show.

Step 4

4.1.3 (b) Why there is a gap between the two runways.

Answer

The gap between the two runways is intentional. It allows passage for people to move freely without obstruction, minimizing the chances of collisions, and enhancing safety and accessibility for all participants and guests.

Step 5

4.1.4 (a) Calculate the area of the top of ONE round table.

Answer

The diameter of the round table is given as 1,828 m, hence the radius will be:

Radius=1,8282=914 m\text{Radius} = \frac{1,828}{2} = 914 \text{ m}

Using the area formula:

Area=3,142×(914)22,627,112.72 m2\text{Area} = 3,142 \times (914)^2 \approx 2,627,112.72 \text{ m}^2

Step 6

4.1.4 (b) Determine the maximum length allocated to each person seated around the round table.

Answer

First, we calculate the circumference of the round table:

Circumference=3,142×1,828 m5,746.09 m\text{Circumference} = 3,142 \times 1,828 \text{ m} \approx 5,746.09 \text{ m}

Then, divide this by the number of people that can be seated at the table:

Length allocated per person=5,746.0910574.609 m\text{Length allocated per person} = \frac{5,746.09}{10} \approx 574.609 \text{ m}
