Write (T) for true and (F) for false against each of the following statements and fill in the blanks:

Here are the solutions to questions 42 to 47. 42. Write (T) for true and (F) for false against each of the following statements: a)* Zero is the smallest natural number. Natural numbers are positive integers starting from 1 (1, 2, 3, ). Zero is not a natural number. ❌ False b)* The predecessor of -6 is -7. The predecessor of a number is found by subtracting 1 from it. -6 - 1 = -7 ✅ True c)* A ray has two end points. A ray has one starting point and extends infinitely in one direction. ❌ False d)* Diameter = (1)/(2) × radius. The diameter of a circle or sphere is twice its radius. Diameter = 2 × radius ❌ False 43. Fill in the blanks: a)* The measure of each angle of a convex quadrilateral is variable (sum is 360^). For a general convex quadrilateral, the measure of each angle can vary, but the sum of all four angles is 360^. If it refers to a regular convex quadrilateral (a square), then each angle is 90^. Given the context, "variable (sum is 360^)" is the most accurate general answer. b)* A figure which ends at the starting point is called a closed figure. c)* Two lines meeting at a point are called intersecting lines. d)* A fraction is a number representing a part of whole. 44. Observe the bar graph carefully and answer the given questions: From the bar graph, the heights of the mountain peaks are: Nanga Parbat: 8100 m Himadri: 7800 m Mount Everest: 8800 m Nanda Devi: $7800
