Maths GL Style 10 Min Test Medium 1 / 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? B E A D C 2 / 14 Which of the following values is the smallest? 1/15 1/25 3.49% 0.05 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% 3 / 14 Sam has £8 more than Rita and £6 less than Lisa. Altogether they have £40. How much money does Lisa have? £20 £15 £6 £13 £14 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 4 / 14 What fraction of the shape is shaded? 2/25 9/25 6/25 1/5 3/10 5 / 14 The volume of this object is 10m³. What is the total surface area? 10m² 20m² 30m² 32m² 36m² 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 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) (2, 6) (5, 2) (1, 7) (5, 2) 7 / 14 What is the weight of each block? 120Kg 100Kg 60Kg 80Kg 40Kg 5 blocks weigh 400Kg So, each block weigh 400 ÷ 5 = 80Kg 8 / 14 Find the value of * 1 0 5 3 7 9 / 14 George has written an expression. When x=3, the value of the expression is 15. Which of the following could NOT be his expression? x (x+2) x³ -12 3x + 3² x² + 6 5x² / 3 3x + 3² = 9 + 9 = 18 All other expressions equal to 15 10 / 14 What's the average number of steps taken over a week? (Round off to the nearest 10) 10000 9760 9200 9640 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 11 / 14 Two fair dice are rolled. What is the probability of getting a sum of 7? 1/6 1/9 1/8 1/4 1/12 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. 12 / 14 Julio jumps 6.656m in a long jump competition. What is the length of the jump to the nearest cm? 6.656m 6.7m 6.6m 6.65m 6.66m 13 / 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? 84 52 110 94 42 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 14 / 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? 1/6 1/2 1/3 1/5 2/5 Number of red marbles = 45 - 25 (blue) - 5 (green) = 15 Probability of picking a red marble = 15 / 45 = 1/3
