28.8
if you times 3.6 by 8 you get 28.8
First we have to find the perimeter. Which is for rectangles 2(l+w)
that means the perimeter is 75.84 ft
each slat is apparently half a foot which would be 0.5ft
then you simply divide 0.5 from 75.84 and round it to the nearest whole number.
The answer is A because if you combine like terms you'll get answer A.try to do it yourself. hope this helps
Answer:
B.(-6,-1)
Step-by-step explanation:
Answer:
Total number of marbles = 10+20+30 = 60 out of which 20 are blue.
Probability of first marble being blue = 20/60
Probability of second marble being blue = 19/59
Probability of third marble being blue = 18/58
Probability of fourth marble being blue = 17/57
Probability of fifth marble being blue = 16/56
So probability of all marble being blue when five marbles are drawn from the box = (20/60)*(19/59)*(18/58)*(17/57)*(16/56) = 34/11977 = 0.00283877432
