14 hours.
Work backwards. From travel, getting ready and sleep he needs 9.5 hours. From 11am to 10:30am is 23.5 hours. Subtracting the two you get 14 hours.
Oven tray: 600 mm by 500 mm
cake tin: 25 cm in diameter
convert mm to cm.
1 cm = 10 mm
600mm * 1cm/10mm = 60cm
500mm * 1cm/10mm = 50cm
Area of oven tray = 60cm * 50cm = 3,000 cm²
Area of cake tin = 3.14 * (25cm/2)² = 3.14 * (12.5cm)² = 3.14 * 156.25cm² = 490.625 cm²
3,000cm² ÷ 490.625cm² = 6.11 or 6 cake tins can fit on the oven tray at one time.
Which of the sets of ordered pairs represents a function? A={(-4, 5), (1, -1), (2, -2), (2, 3)} B = {(2, 2), (3, -2). (9. 3). (9

Answer: Neither A or B
Step-by-step explanation: In order for a relation to be a function, a relation can not have the x-values repeat. Y-values can repeat an infinite amount of times but x-values can only repeat 1 time in a given relation. In relation A, you have (2,-2), and (2,3) and relation B, you have (9,3), and (9,-3). You can also graph both of these relations and do a vertical line test with your pencil and see that it would cross more than once.
