There were 340,000 cattle placed on feed
How many of the 340,000 cattle placed on feed were between 700 and 799 pounds?
Given the fraction of total cattle for 700 - 799 pounds is 2/5
Let x be the number of cattle between 700 - 799 pounds
We make a proportion using the fraction

Cross multiply it and solve for x
340000* 2 = 5x
680000 = 5x
Divide by 5 on both sides
So x= 136,000
There were 136,000 cattle between 700 and 799 pounds
you need to find one side then see what multiples are equal to your answer
These are 3 questions and 3 answers.1) Find
Answer: 4.Explanation:The expression means the
limit as the function f(x) approaches 2 from the right.Then, you have to use the function (the line) that comes from the right of 2 and gets as close as you want to x = 2.
That is the line that has the open circle around
y = 4, and that is the limit searched.
2) Use the graph to determine the limit if it exists.Answer: 

To determine each limit you
use the function from the side the value of x is being approached.Note, that since the two limits are different it is said that the limit of the function as it approaches 2 does not exist.
3)
Answer: - 1
To find the limit when the function is approached to 3 from the left you
follow the line that ends with the open circle at (3, -1).Therefore, the limit is - 1.
