Answer: n = 9</h3>
========================================================
Explanation:
Let's assume that n is not negative. If we tried the smallest nonnegative value, n = 0, then we get
- 30+n = 30+0 = 30
- n/3 = 0/3 = 0
- sqrt(n+16) = sqrt(0+16) = 4
The middle result 0 isn't a natural number. The set of natural numbers is {1,2,3,4,...} which is the set of positive whole numbers.
So we can't use n = 0.
Through trial and error, you should find that n = 9 is the next value we can try such that sqrt(n+16) is a natural number, and so is n/3.
If n = 9, then,
- 30+n = 30+9 = 39
- n/3 = 9/3 = 3
- sqrt(n+16) = sqrt(9+16) = 5
We see that the middle result is now larger than 0 and it's a natural number. The same can be said for the last result as well.
Answer:
b
Step-by-step explanation:
because if you square root 30, the value is: 5.477225575, it is neither 5.4 and 5.5
Answer:
D
Step-by-step explanation:
Multiply both sides by 12 to get x+36<_84.
Then move the constant to the right to get x by itself: x<_84-36
Subtract 36 from 84 to get 48.
Now you're left with x<_48
btw <_ is less than or greater than i just don't know how to place the sign on top of the underscore :/ hope this helped :)
Answer:
Step-by-step explanation:
Do you have the options?
For the vertical line test, you can only use the X once per Y. You can not have more than one X.
Answer:
The publisher must sell 4,632 books in order to break even(total sold equals production costs).
Step-by-step explanation:
So the bookstores are really making $24-10.25 in profit off of each book. This equals $13.75 profit for every book sold.
So you set up an equation:
13.75x=$63,690
x=63690/13.75
x=4632
