,1. Multiple Choice: If \( x \) and \( y \) are inversely proportional
and \( x = 4 \) when \( y = 8 \), what is the value of \( y \) when \( x =
16 \)?
- A) 2
- B) 4
- C) 8
- D) 16
Correct Answer: A) 2
Rationale: Since \( x \) and \( y \) are inversely proportional, \( xy
= k \). Therefore, \( 4 \times 8 = 32 \) and \( 16 \times y = 32 \),
which means \( y = 2 \).


2. Fill-in-the-Blank: The sum of the angles in any triangle is
_______ degrees.
Correct Answer: 180
Rationale: The sum of the angles in a triangle is always 180
degrees due to the geometric properties of triangles.


3. True/False: The equation \( 5x - 3 = 2x + 4 \) has no solution.
- True
