Space and Geometry Easy 2 AThe sum of x and y adds to 190° which is mor e than the angle sum of a triangle (180°). Space and Geometry Easy 3 DThe total number of vehicles = 135 The angle at the centr e for cars = 90 135 ? 360? = 240? Chance and Data Medium 4 CLet D be the diameter of the big wheel (back wheel). Let d be the diameter of the small wheel (fr ont wheel). Accor ding to the question information, D = 3/2 ? d. When the car travels 1 m, the big wheel mak es 6 turns. Ther efore, 6 ? the cir cumference of the big wheel = 1 Cir cumfer ence of the big wheel is πD, ther efore the equation can be pr esented as: 6 × πD = 1….(Equation 1) . Let x be the number of turns the small wheel mak es when the car travels 1m. Using the same logic, we can form the equation x × πd = 1…. (Equation 2) Dividing Equation 1 by Equation 2: 6D xd = 1 6D d x = 6 × 3 2 x = = 9 , make x the subject of the equation: 6D xd = 1 6D d x = 6 × 3 2 x = = 9 Substitute D= 3/2 d D xd = 1 6D d x = 6 × 3 2 x = = 9 .

Rate of incr ease in height of successive dolls is 128 96 12896 700 . Height of doll with 700 dolls inside = 40.5 × 128 96 12896 700 = 1.1603 × 10 89 mm Ther efore, the value of x is 89.
