ABC is a right-angled triangle.

Work out the length of CB. Give your answer correct to 3 significant figures.

Write 90 as a product of its prime factors.

A = 2²3 B = 23²

Write down the lowest common multiple (LCM) of A and B.

The number of hours, H, that some machines take to make 5000 bottles is given by H where n is the number of machines. On Monday, 6 machines made 5000 bottles. On Tuesday, 9 machines made 5000 bottles. The machines took more time to make the bottles on Monday than on Tuesday. How much more time?

There are only red discs, blue discs and yellow discs in a bag. There are 24 yellow discs in the bag. Mel is going to take at random a disc from the bag. The probability that the disc will be yellow is 0.16 the number of red discs: the number of blue discs = 5: 4 Work out the number of red discs in the bag.

Complete the table of values for y = x² – x

On the grid, draw the graph of y = x² – x for values of x from –2 to 3

Use your graph to find estimates for the solutions of the equation x² – x = 4

Andy, Luke and Tina share some sweets in the ratio 1: 6: 14 Tina gives of her sweets to Andy. Tina then gives 12 % of the rest of her sweets to Luke. Tina says, “Now all three of us have the same number of sweets.” Is Tina correct? You must show how you get your answer.

ABCD is a quadrilateral.

All angles are measured in degrees. Show that ABCD is a trapezium.

A playground is in the shape of a right-angled triangle.

Dan makes a scale drawing of the playground. He uses a scale of 1 cm represents 5 m The area of the playground on the scale drawing is 28 cm² The real length of QR is 40 m Work out the real length of PQ.

A number N is rounded to 2 significant figures. The result is 7.3

Write down the least possible value of N.

Leila says, “The value of N cannot be greater than 7.349 because 7.350 would round up to 7.4”

Is Leila correct? You must give a reason for your answer.

The diagram shows two right-angled triangles.

All lengths are measured in centimetres. Given that sina = tanb work out the value of x.

The frequency table gives information about the weights of 60 parcels.

Weight (wkg)	Frequency
0 w 2	7
2 w 4	21
4 w 6	15
6 w 8	11
8 w 10	6

Complete the cumulative frequency table.

On the grid opposite, draw a cumulative frequency graph for your table.

Use your graph to find an estimate for the interquartile range.

Use your graph to find an estimate for the number of these parcels with a weight greater than 7.4 kg.

f is inversely proportional to d² f = 3.5 when d = 8

Find an equation for f in terms of d.

Find the positive value of d when f = 10 Give your answer correct to 3 significant figures.
