The limit of f(x) at x=-1 is 5 when approached from the left or right. Since those limits are the same, the limit exists and is ...
A 2,768–foot–long straight fence has posts that are set 8 feet on center; that is, the distance between the centers of two adjac
ent poles is 8 feet. If the fence begins with a post and ends with a post, determine the number of posts in the entire fence.\
1 answer:
Answer:
No.P=347
Step-by-step explanation:
The fence is 2768 feet long, how many posts should be placed along the fence if the adjacent distance between them is 8 feet?
How to start and end with a post the number of them (No.P) will always be the distance of the fence (f) between the adjacent distance of the posts (p) plus one

Answer: a) Number of nickels, dimes, and quarters are 80, 120, 300 respectively.
b) The coins are worth of 91 dollars i.e. $91 in the piggy bank.
Explanation:
Since we have given that
For every 2 nickels there are 3 dimes ,
So, their ratio will be 2:3
and for every 2 dimes there are 5 quarters.\,
So, their ratio will be 2:5
Now, we'll first find the ratio of nickles to dimes to quarters i.e.
Nickle Dimes Quarters
2 3
2 5
So, it becomes ,
Nickle : Dimes : Quarters
2×2 : 3×2 : 3×5
4 : 6 : 15
Now, let the number of nickle be 4x
Let the number of dimes be 6x
Let the number of quarters be 15x
According to question,
So, number of nickels is given by
Number of dimes is given by
Number of quarters is given by
As we know that
So, According to our question, we get
Hence,
a) Number of nickels, dimes, and quarters are 80, 120, 300 respectively.
b) the coins are worth of 91 dollars i.e. $91 in the piggy bank.
