<span>Divide the pages printed by the minutes used.
7 pages / 3 minutes = 2.33 = 2.33 pages per minute.
30 / 5 = 6 lbs for one acre..........1 / 6 = 1.6666 acres per pound</span><span>
this is the write answer

The second one is the correct answer!
Answer:
(-4, 7)
Step-by-step explanation:
It would be the exact opposite of point R because it was rotated about 180 degrees from it's original location
Answer:the domain is every “x” coordinate and the range is the “y” coordinate
Step-by-step explanation:
If you have to tell whether it’s a function or not, all of the x values in the domain will be different for a function, and 2 or more of the same x value won’t be a function
<span>This is a rectangular field, it will have four fence in one direction, and two in the other.
The vertical lines here are the same length on each other, likewise of the horizontal line.We can calculate the length of the fence from them as:
4V + 2H= L
we also have three area added together come to 800:
3VH = 800
so, lets re-arrange that second equation
H=800/3V
And sub into the first:
4V + 1600/3V = L
Multiply through by 3V:
12V^2+1600= 3LV
Rearrange
12V^2 - 3LV+ 1600= 0
we have quadratic, lets take a look at discriminant with this quadratic
discriminant= b^2 - 4ac
discriminant= 9L^2 - 4*12*1600
discriminant= 9L^2 - 76800
the dicriminant must be positive so the following must be true
9L^2>=76800
L^2>=8533.33
L>=92.376
so 92.36 is answer</span>
