Explanation

Set A is a subset of B because all elements of A are present in B.

Symbol ⊂ means "is a subset of".

Explanation

Given sets A = {1, 2, 5, 3} and B = {3, 4}, and assuming the universal set U = {1, 2, 3, 4, 5}:

Step 1: Find B'

B' = U - B

= {1, 2, 3, 4, 5} - {3, 4}

= {1, 2, 5}

Step 2: Find A ∩ B'

A ∩ B' = {1, 2, 5, 3} ∩ {1, 2, 5}

= {1, 2, 5}

Explanation

Prime factorization:

30 = 2 × 3 × 5

24 = 2³ × 3

18 = 2 × 3²

Common factors: 2 × 3 = 6

HCF = 6

Explanation

3/7 mile = 10 min. 10/3 = 3.334 min = 1/7 mile. 3.334 x 7 = 23.334 min, = 1 mile 23.334 min. - 10 min. = 13.334 min. or 13 1/3 min. 60 sec./3 = 20 sec. 

It will take 13 minutes and 20 seconds to walk the rest of the mile.

Explanation

Note: The answer given in FPSC answer key is (c) but actual answer is (b).

The angle made by two lines is called an angle itself, and the point where the two lines meet is called the vertex.

Among the given options:

• Segment refers to a part of a line with two endpoints.
• Vertex is the correct term for the point where the two lines meet and form an angle.
• Rays refer to lines that extend indefinitely in one direction from a point.
