A, B and C are three points on a grid. A is at (5, 2), B is at (4, 5) and C is at (3, 0).(a) Plot and label the other two points, B and C, and then join the three points and lightly shade the triangle you have formed. (b) State the name of the type of triangle that has been formed.ScaleneIsocelesEquilateralRight anglenone of the above A mirror line is marked as the dotted line at x = 3. The triangle can be reflected in this mirror line so that point A ends up at a new point D and point B ends up at a new point E. (c) Draw the reflected image of the triangle across this mirror line and label the two new points D and E. (d) Write down the co-ordinates of these new point D and E: Answer: D is at ( , 2) and E is at ( , )D=(1,2),E=(2,5)D=(1,1),E=(2,5)D=(1,2),E=(5,2)D=(2,2),E=(2,5)D=(1,3),E=(2,5) One of these new points, D or E, can be joined up to point A and to the origin to create an isosceles triangle.(e) Write down which new point completes this triangle in the diagram and explain briefly what it means for a triangle to be isosceles.Point will form an isosceles because an isosceles triangleE,because isoceles have 2 sides equalD,because isoceles have 3 sides equalB,because isoceles have 2 unequal sidesA,because isoceles have 2 sides equalnone of the above 13.

Each paving slab is a square with sides 1 metre.(c) Work out how many paving slabs are needed to complete this path. Answer:3640461620 15. continued: Louis hires a builder to lay the path. The builder charges £8 per hour basic labour for the job, and then £1.50 per slab he lays.(d) If he takes 3½ hours to finish the job, work out his overall fee.£ 82£ 72£ 79£ 75£ 85 Louis then decides to plant a row of bushes around the inside of the stone path.Each bush is to be planted 25 cm from the edge of the path, and 50 cm from itsneighbouring bushes. The diagram below display how this might look near a corner of the garden.(e) Calculate how many bushes are required to complete this in total.6028503080 16. In five of this mid-term tests, each out of 10 marks, Darshan scores 9 in Mathematics, 6 in English, 8 in Geography, 4 in History and 8 in Science.(a) Write down the mode of Darshan's five scores. Answer: marks864910 (b) Work out the range of marks that Darshan scores. Answer: marks51342 (c) Calculate the mean average score that he achieved in these five tests. Answer: marks76548 (d) After his French mark is announced, Darshan's average score from all six tests falls to 6.5 marks. Calculate the mark he score in his French test. Answer: marks41568 (e) The pass mark for each test is 50%. Write down what fraction of Darshan's six tests(including his French) he managed to pass, leaving your answer in its simplest form. Answer: marks\[\frac{2}{3}\]\[\frac{1}{3}\]\[\frac{1}{5}\]\[\frac{2}{7}\]\[\frac{1}{6}\] 16. continued: In the end of term tests, Darshan scores 15 out of 20 in his History.(f) Work out what his percentage improvement is in this subject.

Answer: minutes8mins4mins12mins16mins6mins (b) Work out how many chimps would be required to eat 21 bananas in 8 minutes.(You can assume that the tree has a large number of bananas available and that the chimps all have big appetites!) Answer:798610 19. The sixteen shapes in the grid each contain a number with the following rules: The numbers in the circles are four more than the numbers in the squares on the same row. The numbers in the triangles are double those of the numbers in the squares on the same row. (a) Complete the missing numbers in the square. (b) Complete the missing numbers in the circles and triangles. (c) Identify the pattern that links the other numbers to the hexagonal numbers in each row. Write one of the four arithmetic symbols (+ , - , × , ÷) in each of the two gaps either side of the circle, to complete the following formula linking all the numbers in any row of shapes.Answer: (d) Complete the grid above by adding the appropriate number to the empty hexagon, using your formula. (e) If a fifth row is added below the four displayed, write down what number would be in the fifth hexagon. Time is Up! Time's up
