Answer:
5832 ways
Step-by-step explanation:
Since the circle has 8 sectors and there is 4 colour,
Assuming the sectors are numbered 1 to 8,
Sector 1 : can be coloured with any of the 4 colour in 4 ways
Sector 2 can be coloured with any of the remaining 3 colours in 3 ways
Sector 3 in 3 ways without using the colour in sector 2
Sector 4 in 3 ways without using the colour in sector 3
Sector 5 in 3 ways without using the colour in sector 4
Sector 6 in 3 ways without using the colour in sector 5
Sector 7 in 3 ways without using the colour in sector 6
Sector 8 in 2 ways without using the colours in sector 1 and 7
Number of ways of colouring = 4*3*3*3*3*3*3*2 = 5832 ways
Answer: -2.1, -0.5, 5/100, 0.5, √5
Step-by-step explanation:
Start with the negative numbers. Take the absolute value - the ones with the largest absolute value are the farthest from 0, so they are the smallest numbers.
-2.1, -0.5
Then, convert the numbers not in decimals to decimals.
5/100 = 0.05
√5 is about 2.3.
5/100, 0.5, √5
