Not a triangle because the two smaller numbers do not add up to a bigger number than 15

Answer: C) -81/2</h3>
===================================================
Work Shown:
a = -27 = first term
r = 1/3 = common ratio, note how this is between -1 and 1
We start with -27 and multiply by 1/3 each time to get the next term
S = infinite sum
S = a/(1-r), which only works because -1 < r < 1 is true
S = -27/(1-1/3)
S = -27/(2/3)
S = (-27/1) divided by (2/3)
S = (-27/1) times (3/2)
S = (-27*3)/(1*2)
S = -81/2
As you generate and add up the terms of the sequence, the infinite sum slowly starts to approach -81/2 = -40.5; we'll never actually achieve this sum exactly. Think of it as approaching an asymptote.
Answer:
2 rooms
Step-by-step explanation:
1/2 divided by 1/4 is 2
2 times 1 = 2
Answer - 2
It would be a 50/50 chance, because there is only two different things it could land on, and for each there is a 50% chance for it to land on that side so.
