Answer:
16.2 units
Step-by-step explanation:
Greater angle: 180 - 72 = 108
D² = 10² + 10² - 2(10)(10)cos(108)
D² = 261.8033989
D = 16.18033989
4/105 In total there are 2+4+1+8=15 The probability of taking a blue is number of blue divided by number of total, so that would be 4/15. Since, it is not replaced, we can now say that there are 1 less marbles in the bag (since we took out a blue). Now probability of getting a green marble is:2/14=1/7
$7.18 / 2 = $3.59 per pound
.........................................
so 1 lb = $3.59
2 lbs = 2* $3.59 = $7.18
3 lbs = 3 * $3.59 = $10.77....
2x - 8 < 12
2x < 12 + 8
2x < 20
x < 20/2
x < 10
