Answer:
- Question 1a. i)

- Question 1a. ii)

- Question 1b)

Explanation:
<u><em>Question 1 a. i) Find the value of x.</em></u>

For the smalll triangle you can write:

For tthe big triangle:

Substitute:

Solve for x:

<u><em>Question 1a ii) Find the volume of the frustrum</em></u>
- Find the volume of a cone with height = 2.7m + 1.8m = 4.5m, and radius = 2.5m
Formula:

Substitute:

- Find the volume of a cone with heigth = 1.8m and radius = 1m

- Subtract the volume of the small cone from the volume of the big cone

<u><em>Question 1b. Calculate the volume of the bin</em></u>
<u>i) Upper frustrum</u>
This is the same frustrum from the equation of above, thus ist volume is 27.6m³.
<u>ii) Lower frustrum</u>




<u>iii) Add the volume of the two frustrums</u>
Example-A statistical question is a question that can be answered by collecting data that vary. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question.
Answers- A, C, D and E
28m(cm/5.5m)=56/11 cm
≈5.1 cm (to nearest tenth of a centimeter, or to nearest millimeter)
Answer for the first dropdown box is CAF and EFH
Answer for the second dropdown box is because they are corresponding angles of parallel lines cut by a transversal
Answer for the third dropdown box is transitive property of congruence
------------------------------------------------------------------------------
Explanation:
Angles CAF and EFH are corresponding angles because they are on the bottom side of the parallel lines, and on the right side as well. So they are congruent (due to the lines being parallel).
Since CAF = EFH and EFH = HFD, this means that CAF = HFD
It's similar to saying if x = y and y = z, then x = z. Think of it as a connecting chain. This is the transitive property.
