Answer:
The first answer choice, 4632.5
Step-by-step explanation:
At the rate of 85 feet per hour, after 5.5 hours the apprentice would have covered 467.5 square feet. Subtracting this from the total amount of 5,100 square feet, you get 4632.5, or the first answer choice. Hope this helps!
<span>the discriminant formula is D = b^2 - 4ac
(idk how to put graphs or anything but yeh)

- First multiply 1/3 times 1/6 across giving you 1/18
-then get the LCD of 5/9 and 1/18 which is 18
multiply 5/9 times 2/2 to get 10/18.
-Now you can subtract
10/18- 1/18 = 9/18
-further simplify by diving the top and bottom of 9/18 by 9
the answer would be =1/2
<em>*Note: you do not need to get the LCD of a fraction when multiplying or dividing. You DO need the LCD when adding or subtracting a fraction.</em>
if (x - 5 ) is a factor of f(x ) then x = 5 is a root of f(x) and f(5) = 0
