Answer:
There are 1500 non fiction books and 500 fiction books currently in the store.
Step-by-step explanation:
Given:
Total Number of books = 2000
Let the number of fiction books be 'x'.
Now given:
There are 3 times as many non-fiction books as fiction books.
Number of non fiction books = ![3x](https://tex.z-dn.net/?f=3x)
We need to find the number of non-fiction and fiction books.
Solution:
Now we know that;
Total Number of books is equal to sum of the number of non-fiction and fiction books.
framing in equation form we get;
![x+3x=2000\\\\4x=2000](https://tex.z-dn.net/?f=x%2B3x%3D2000%5C%5C%5C%5C4x%3D2000)
Dividing both side by 4 we get;
![\frac{4x}{4}=\frac{2000}{4}\\\\x= 500\ books](https://tex.z-dn.net/?f=%5Cfrac%7B4x%7D%7B4%7D%3D%5Cfrac%7B2000%7D%7B4%7D%5C%5C%5C%5Cx%3D%20500%5C%20books)
Number of fiction books = 500
Number of non fiction books = ![3x=3\times 500 =1500](https://tex.z-dn.net/?f=3x%3D3%5Ctimes%20500%20%3D1500)
Hence There are 1500 non fiction books and 500 fiction books currently in the store.

Answer:
329.5
Step-by-step explanation:
From the table we see that the common difference d = 0.5 - (-6.5)
= 7, and 7.5 - 0.5 = 7. Also 14.5 - 7.5 = 7.
The first term a1 = -6.5.
The nth term = a1 + (n - 1)d so for our sequence we have:
49th term = -6.5 + (49 - 1)7
= -6.5 + 48 * 7
= -6.5 + 336
= 329.5 (answer).
