Answer:
Step-by-step explanation:
Sum of all the angles of 12 sided polygon= (n -2)*180
= (12 - 2 )*180 = 10 * 180 = 1800
Four interior angle each of xº + 8 interior angles each of 2xº = 1800
4*x + 8*2x = 1800
4x + 16x = 1800
20x = 1800
x = 1800/20
x = 90°
Answer:
Ahmed has more toffees
Ben has more chocolates
Step-by-step explanation:
Ahmed:
60% = 3/5
3/5 x 30 = 18
therefore out of 30, 18 are toffees.
30 - 18 = 12
therefore 12 are chocolates
Ben:
3/8 x 40 = 15
therefore out of 40, 15 are toffees
40 - 15 = 25
therefore 25 are chocolates
By the way I am not sure!

Step-by-step explanation:
Whilst it seems an unlikely scenario, unless we have reason to believe Susie is not making a random choice but is making a free selection, then the previous withdrawals make no difference as the marble is returned each time. Therefore the probability is the same as at the beginning which is 5 red / 15 total marbles, or 1 in 3.
