Ring lights are the best lighting option for close-up photography and videography - NSC Mathematical Literacy - Question 2 - 2023 - Paper 2

From the item list in ANNEXURE B, the item identified as the ring light stand is labeled as a 'Tripod'. This is a standard component used for stability in lighting setups.

The direction of the arrow in diagram B is clockwise. This indicates the direction in which the component should be rotated during assembly.

(a) The correct picture for clamping the cellphone to the cellphone holder is picture H. (b) The correct picture for installing the tripod on the pan-tilt and rotating until tightened is picture G.

To determine the distance on the wall map, use the scale of 1 : 250,000. First, convert 65 kilometers to meters:

$65 ext{ km} = 65,000 ext{ m}$

Next, apply the scale:

$ext{Map Distance} = \frac{65,000 ext{ m}}{250,000} = 26 ext{ cm}$

Thus, the distance on the map is 26 cm.

One other type of scale commonly used on maps is a bar scale. This graphical representation allows users to measure distances directly on the map.

First, calculate the total volume of one ream of paper:

$\text{Volume} = L \times W \times H = 27.94 ext{ cm} \times 21.59 ext{ cm} \times 6.35 ext{ cm}$

Calculating this gives:

$\text{Volume} \approx 3,646.92 ext{ cm}^3$

Next, calculate the volume of the shelf:

$\text{Shelf Volume} = 102 ext{ cm} \times 44 ext{ cm} \times 39 ext{ cm}$

Calculating this gives:

$\text{Shelf Volume} \approx 182,568 ext{ cm}^3$

Now, to find out how many reams can fit, divide the shelf volume by the single ream volume:

$\frac{182,568 ext{ cm}^3}{3,646.92 ext{ cm}^3} \approx 50.07$

Thus, all 36 reams can fit on one shelf.

One reason the teacher would like to pack the reams of paper in the cabinet is to keep them dry and moisture-free. This helps to maintain the quality of the paper, preventing damage and ensuring it remains usable.
