<span>They're analogous to planes, but obviously not planes, since they have three dimensions.
A point would be a person in the building.
A segment would be a hallway or elevator shaft.
I can't think of anything that would be analogous to a ray.</span>
First we have to solve the inequality
subtract 8 from both sides to get
this means that any number greater than or equal to three will make this inequality true as such you can say, 3,4,5 or 4,8,10 or even 34, 100, 44 the three numbers selected just have to be greater than or equal to 3.
Answer:
950
Step-by-step explanation:
The common difference is 4, so the general term can be written:
... an = 14 + 4(n -1)
The value of n for the last term is ...
... 86 = 14 + 4(n -1) . . . . . the computation for the last term, 86
... 72 = 4(n -1) . . . . . . . . . subtract 14
... 18 = n -1 . . . . . . . . . . . divide by 4
... 19 = n . . . . . . . . . . . . . add 1
Your series has 19 terms. The first term is 14 and the last is 86, so the average term is (14+86)/2 = 50. Since there are 19 terms, the sum of them is ...
... 19×50 = 950
Final Answer: 2g + 1/18
3g - 1g - 1/9 + 1/6
2g - 1/9 + 1/6
- 1 × 2 -2
------- -------
9 × 2 18
+ 1 × 3 3
------- -------
6 × 3 18
