There will be a garden party at Bodnant Garden in July. Unfortunately, there has been a flood which has damaged one part of the gardens. It is essential that this area is repaired before the garden party as this is where the people will be sitting to enjoy their cups of tea. For this area to look its best, 1800 pansies and 1800 tulips must be planted. 1 gardener can plant 90 pansies in one day or a 1/3 as many tulips. The garden will need time to settle, and must be ready within 10 days. How many gardeners must they employ to ensure that the garden is ready within the time limit given? You will need to show your full working out and will need to explain your work. For the pansies to be planted 1800 ÷90 = 20 days. This means that it would take 20 days for 1 person to plant all of the pansies. Therefore, with 2 gardeners it will take half the time which is 10 days. For the tulips to be planted We must consider how many could be planted in a day. In 1 day, 90 ÷3 = 30 tulips could be planted. 1800 ÷ 30 = 60 days. This means that it would take 60 days for 1 person to plant all of the pansies. 60 ÷ 6 = 10 days. It would take 6 gardeners 10 days to plant all of the tulips. Total number of gardeners needed is 2+6=10 to ensure that the pansies and tulips are all planted within 10 days. Constructing an angle with only a Compass.

QUESTION 13 129 Draw a straight line in your books. To bisect this line means that we must split it exactly in half using only compasses. To do this you must place the pin at one edge of the line and open the compass out beyond half way. Draw an arc. Repeat this step from the other side. Both arcs should cross over. From the crossover points, draw a straight line. http://www.mathsisfun.com/geometry/construct-linebisect.html Real Life Money Questions. QUESTION 14 64 Exchange rates Luke goes on a skiing holiday to Switzerland. He buys £500 worth of Swiss Francs which gives him 700 Swiss Francs. Can you work out the exchange rate? If he has 300 Swiss Francs left after returning home, how many pounds would he expect to have back? To work out the exchange rate we must do 700 ÷ 500 = 1.40 This means that for every £1 you receive 1.40 Swiss Franc. 300 Swiss Francs are 300 ÷ 1.40 = £214.29 (rounded to 2 d.p. as it’s money) Time Zones. QUESTION 14 64 Time Zones Mr Davies is delighted that the school have been to San Francisco. As a result, he would like to contact the hotel they stayed at in San Francisco to thank the manager for the welcome that YJB received. He is able to call on a Thursday. He knows that the time difference between Llandudno and San Francisco is 8 hours (San Francisco is 8 hours behind Llandudno). What time and day should he call from Llandudno if the manager works from 8:00am to 5:00pm? 8:00am in San Francisco is 8+8 = 4pm in Llandudno on the Thursday. 5:00pm in San Francisco is 1am in Llandudno on the Friday. Mr Davies could call between 4:00pm om Thursday and 1:00am on Friday.
