The table below shows the highest and lowest temperatures in °C recorded in six cities around the world on one particular day last year(a) What is the difference between the highest and lowesttemperatures in Boston? (b) What is the difference between the highest and lowesttemperatures in St Petersburg? (c) Which city has the lowest recorded temperature of all? (d) Which city has the largest difference between itshighest and lowest temperature? 2. The gas meter reading on Andrew’s smart meter in October was 5475 units. Exactly three months later, in January, the reading was 6045 units. M-power charge a fixed amount of £16.20 each month plus 40p for each unit used during the three months between the two readings.(a) How many units of gas has Andrew used in the threemonth period from October to January? (b) Calculate the total amount Andrew has to pay for that threemonth period. (c) In fact, M-power also have to add 5% to Andrew’s bill whichis the tax known as VAT. What will be the final bill that Andrewhas to pay for his gas? 3. The “Blast” of a two digit number is obtained as follows:The Blast of 63 is 216 because 6 x 6 x 6 = 216and the Blast of 27 is 128 because 2 x 2 x 2 x 2 x 2 x 2 x 2 = 128(a) Write down the Blast of the two digit number 34 (b) Which two digit number has a Blast of 125 (c) Work out another two digit number which has the same Blast as 24 (d) A particular two digit number is Blasted and then that answeris also Blasted. If the final answer is 9, what was the original number? 4. A plant grows during the first month after it is planted. During the second month it grows by half the height it had already reached. During the third month it grows by one third of the height it had reached at the end of the second month. It then grows by one quarter and one fifth of the height reached in the same way in the next two months.(a) If a plant is 1 metre tall at the end of the first month,how tall will it be after five months? (b) If a plant grows 90 cm in the third month,how tall was it after one month? (c) If a plant is 2 metres tall at the end of the first month,how much will it have grown, in total, by the end of thefifth month? 5. The table below shows four different makes of car each with four different engine sizes, in litres, and the Insurance Group for each. For example a Hissan 1.5 car is in Insurance Group B.The second table shows the monthly insurance payment paid by drivers of different age bands for each of the insurance groups, so a person aged 37 would be in the age band 21 - 45 and so would pay £105 each month for a car in Insurance group C.(a) How much will a 19 year old pay for a Foxhall 1.5 careach month? (b) A 30 year old pays £95 for a Hissan car. What is the enginesize of their car , in litres? (c) How much would a 50 year old person save each month byusing a 1.1 Hissan car rather than a 1.9 Hissan car? (d) If a 32 year old pays £95 for a Skoyota car, what would a 20year old pay for a Jagley car with the same size engine? 6. If the weight of straight bones in the human body depends on the length, radius and density of the bone using the following formula Weight = Length x Radius x Radius x Densityor W = L x R x R x Dthen a shin bone of length 40cm, radius 3cm and density 5 would have a weight of 1800g because W = 40 x 3 x 3 x 5 = 1800Using this formula,(a) Work out the weight of a finger bone of length 3cm,with a radius of 0.5cm and density 2. (b) Work out the density of a forearm of length 30cm,with a radius of 2cm which weighs 480g. (c) Work out the radius of a thigh bone of length50cm which has a density of 8 and weighs 3600g. 7. A top international bowler playing in a cricket match bowls a cricket ball at 90 miles per hour.(a) How many miles would the ball travel in one minute? (b) If a mile is 1760 yards, how many yards would theball travel in one minute? (c) How many yards does the ball travel in one second? (d) If the distance the ball travels through the air from the pointwhere the bowler bowls the ball to the point where it is hitby the batsman is 22 yards, how long is the ball travelling for? 8. Complete all the entries in the table below showing the sum, difference, product and quotient for pairs of numbers from the first two columns. The first row is completed as an example to help you. 9. Megaprint make small business cards with names and contact details on, that people can give to clients as part of their work. The total cost of buying the cards they sell is made up of two amounts.There is a fixed cost that people must pay no matter how many cards they order and this amount is always the same. Then there is a second amount which depends on the number of cards ordered. These two amounts are added together to give the total cost of the order and the graph below shows what the total cost would be for the number of cards ordered.Using the graph(a) Write down the total cost of having 100 cards printed. (b) Andy’s order costs him £16.00. Write down the numberof cards he ordered. (c) If 200 cards are ordered, using the total cost what isthe cost of one card? (d) Write down the fixed cost that Megaprint charge foreach order, regardless of the number of cards ordered. (e) If you exclude the fixed cost, how much is charged for onecard to be printed? Maxicard also make business cards but they charge a fixed cost of £6.00 for an order and the total cost of 500 cards is £16.00.(f) Mark two points on the graph and join them with a straightline to show this information. (g) Using the graph, or otherwise, work out the number of cardsfor which the total cost would be the same from both companies. 10. A two digit number is called a multisum if it is a multiple of the sum of its digits. So 84 is a multisum since 8 + 4 = 12 and 84 is a multiple of 12(a) Work out and write down the smallest number, greaterthan 50, which is a multisum. (b) Work out and write down the smallest multiple of 7 whichis a multisum. (c) Work out and write down the only multiple of 9 which isNOT a multisum. (d) Work out and write down all the numbers between20 and 30 which are NOT multisums. 11. A pair of numbers written as a column like thisis known as a VEC.VECs can be combined together in two different ways, as follows(a) Work out the value of Time is Up!
