A road contractor has to transport 240 tonnes of hardcore. He will use two types of lorries, type A and type B. He has 3 type A lorries and 2 type B lorries. The capacity of each type A lorry is 8 tonnes while that of type B is 15 tonnes. All type A lorries must each make the same number of trips. Similarly all type B lorries must each make the same number of trips. The number of trips made by each type B lorry should be less than twice those made by each type A lorry. Each type A lorry must not make more than 6 trips.KCSE 2020 MATHEMATICS ALT A PAPER 2 QUESTION 21An aircraft took off from point A (x degrees North, 15 degrees east) at 0720h, local time.

A tailor makes two types of garments A and B. Garment A requires 3 metres of material while garment B requires 2 Â½ metres of material. The tailor uses not more than 600 metres of material daily in making both garments. He must make not more than 100 garments of type A and not less than 80 of type B each day.(a). Write down all the inequalities from this information. (3mks)b) Graph the inequalities in (a) above (3mks)c) If the business makes a profit of shs. 80 on garment A and a profit of shs. 60 on garment B, how many garments of each type must it make in order to maximize the total profit? (4mks)The curve of the equation y = x+ 2x^{2}, has x = ½ and x = 0 as xintercepts. The area bounded by the xaxis, x = ½ and x = 3 is shown by the sketch below.a) Using a ruler and pair of compasses only construct triangle ABC in which AB = 6.5cm, BC= 5.0cm and angle ABC = 600. Measure AC (3mks)
