When x=3, the value of the expression is 15. Which of the following could NOT be his expression? 3x + 3² x (x+2) x² + 6 x³ -12 5x² / 3 3x + 3² = 9 + 9 = 18 All other expressions equal to 15 2 / 14 A pot contains 45 marbles. 25 of the marbles are blue, 5 of the marbles are green, and the rest of the marbles are red. If a marble is drawn at random, what is the probability that it is red? 1/2 1/5 1/3 1/6 2/5 Number of red marbles = 45 - 25 (blue) - 5 (green) = 15 Probability of picking a red marble = 15 / 45 = 1/3 3 / 14 The pie chart shows the proportion of different colours of cars in a showroom. There are 200 cars in the showroom. How many red cars are there? 42 84 94 52 110 Sum of all colours of cars should be 100% ie. 8% + 30% + 20% + Red Cars % = 100% ie. 58% + Red Cars % = 100% % of Red Cars = 100-58 = 42% There are 200 cars in the showroom. Hence total number of red cars = 42% of 200 = 84 4 / 14 The volume of this object is 10m³. What is the total surface area? 10m² 30m² 32m² 36m² 20m² There are 10 cubes and the total volume is 10m³ The volume of each cube is 1cm³ ie. each side is 1m. We know each flat face of the cube is a square - the surface area of each face is 1m x 1m = 1m² Total surface area = Number of visible cube faces x 1m² If you look at the object from all sides, top (6) + bottom (6) + left (4) + right (4) + front (5) + back (5) = 30 faces with surface area of 1m² each Hence, total surface area = 30 x 1 = 30m² 5 / 14 Which of the following values is the smallest? 1/15 1/25 0.05 3.49% 3.6% To determine which number is the smallest, we need to convert all the values to the same format (ie. decimal format) for easy comparison. A. 3.6% = 3.6 / 100 = 0.036 B. 1/25 = 0.04 C. 0.05 D. 3.49% = 3.49 / 100 = 0.0349 E. 1/15 = 0.0667 Now we can compare the values: A. 0.036 B. 0.04 C. 0.05 D. 0.0349 E. 0.0667 The smallest value is 0.0349 So, the answer is D. 3.49% 6 / 14 The end points of five lines are shown in the answer options below. Which line is parallel to the line in the diagram? (1, 6) (6, 2) (1, 6) (5, 3) (1, 6) (5, 2) (1, 7) (5, 2) (2, 6) (5, 2) 7 / 14 What's the average number of steps taken over a week? (Round off to the nearest 10) 9200 9760 9640 10000 9786 Steps: 9000, 8000, 9000, 8500, 10000, 12000, 11000. Average = (9000 + 8000 + 9000 + 8500 + 10000 + 12000 + 11000) / 7 = 9642.85 steps. Rounding off to nearest 10 -> 9640 8 / 14 What is the weight of each block? 100Kg 120Kg 60Kg 80Kg 40Kg 5 blocks weigh 400Kg So, each block weigh 400 ÷ 5 = 80Kg 9 / 14 The image on the left is rotated clockwise by 90 degrees and then flipped horizontally (as if reflected on a vertical mirror). Which one is the resulting image? A B C E D 10 / 14 What fraction of the shape is shaded? 3/10 2/25 1/5 6/25 9/25 11 / 14 Julio jumps 6.656m in a long jump competition. What is the length of the jump to the nearest cm? 6.7m 6.6m 6.66m 6.656m 6.65m 12 / 14 Sam has £8 more than Rita and £6 less than Lisa. Altogether they have £40. How much money does Lisa have? £6 £14 £13 £20 £15 Let's say Sam has X pounds So, Rita has X - 8 pounds Lisa has X + 6 pounds Altogether they have £40 Given the above, X + (X - 8) + (X + 6) = 40 3X - 2 = 40 3X = 42 X = 14 Sam has £14, Rita has X - 8 = £6 , Lisa has X + 6 = £20 13 / 14 Find the value of * 7 5 1 3 0 14 / 14 Two fair dice are rolled. What is the probability of getting a sum of 7? 1/9 1/6 1/8 1/12 1/4 The pairs that give a sum of 7 are (1,6), (2,5), (3,4), (4,3), (5,2), (6,1). There are 6 such outcomes out of 36 total, so the probability is 6/36 = 1/6.
