Answer:
4,000
Step-by-step explanation:
Well if u multiply 305feet by 1/100 in your calculator you'll get 3.05ft tall
By definition, if 
is the least upper bound of the set 
, it means two thing:
In other words, the least upper bound of a set is greater than or equal to every single element of the set, but it is "close enough" to the elements of the set, because you guaranteed to find elements in the set between 
and 
For example, pick 
. Obvisouly, the least upper bound is 
. In fact, every number in 
is smaller than 10, but as soon as you take away something from 10, say 0.01, you get 9.99, and there are elements in greater than 9.99, say 9.9999.
So, the claim is basically proven by definition: if 
, let 
. By definition, there exists 
.
Remark
Remove the brackets. Then solve as a normal inequality.
Solution
4(x - 3) - 2(x - 1) > 0
4x - 12 - 2x + 2 > 0 Combine like terms on the left
4x - 2x - 12 + 2 > 0
2x - 10 > 0 Add 10 to both sides
2x > 10 Divide by 2
x > 10/2
x > 5
Answer: B
Discussion
C and D are both true but these questions always assume that you are going to pick the lowest value that will allow the inequality to be true. x> 7 and x>14 will be included in x>5
The answer is 230. Good luck
