3.1 Calculate, in rand per minute, the rate for solo flying - NSC Mathematical Literacy - Question 3 - 2019 - Paper 2

The total approximate cost for a private pilot's licence is calculated by adding all components:

1. Flight with instructor: 28 hours at R2 050 per hour = R57 400
2. Solo flying: R31 050
3. Ground lessons: 15 hours at R1 242,42 per hour = R18 636,30
4. Ground school fees: R700
5. Flying kit: R6 544
6. Examinations: 7 at R190 each = R1 330

Total Cost: $R57,400 + R31,050 + R18,636.30 + R700 + R6,544 + R1,330 = R115,660.30$

We need to calculate the total amount after two years with compound interest:

Given:

• Principal (P): R90 000
• Rate (r): 8.5% per annum
• Time (t): 2 years

The formula for compound interest is: $A = P(1 + r/n)^{nt}$ Assuming interest is compounded yearly (n=1): $A = R90 000(1 + 0.085)^2$ Calculating gives: $A = R90 000(1.085)^2 = R90 000(1.177225) = R105 950,25$

Since R105 950,25 is less than the total cost of R115,660.30, the total amount is not enough.

Students might have gained more experience from their first attempt and were better prepared for the second. They may have learned from their mistakes and had more practice before retaking the examination. This additional preparation likely improved their chances of passing.

From TABLE 2:

• A's pass rate is 20%, so: $A = 24/0.2 = 120$
• B’s pass rate from the second attempt is 30%, so: $B = 67/0.3 = 29$
• C = total number of students = 96
• D = number who passed = 96 - 29 = 67.

Thus, the total number of students that passed after both attempts: $24 + 29 = 52$.

To verify the conversion of 26 000 flying hours:

1. Convert total hours to days: $26,000 \text{ hours } = \frac{26,000}{24} \approx 1083.33 \text{ days}$
2. Days in weeks: $\frac{1083.33}{7} \approx 154.76 \text{ weeks}$
3. It confirms that the statement is valid since both calculations align with the given data.

The total number of loose parts in a box is derived from ANNEXURE E. Counting all the visible parts in the illustration yields a total of 33 loose parts.

1. Place the bench face down.
2. Attach the legs to the bench seat correctly, ensuring they align with the pre-drilled holes.

The long panel serves as the main support for the bench structure. It connects the legs and provides stability, ensuring that the assembled bench is sturdy and capable of bearing weight.
