3 hours is equivalent to 180
minutes.
The amount of remaining time is
150 minutes.
Since there are still 30
remaining papers left, therefore:
Time allotted per paper =
150minutes/30papers = 5 minute per paper
The time allotted for the 5
finished papers is:
Time allotted before =
30minutes/5papers = 6 minutes per paper
<span>Therefore she must work 1 minute per paper faster.</span>
Answer:
1 1/2.
Step-by-step explanation:
If 1/2 of a cup covers 1/3 add it twice you get 2/2 and you get 2/3 add it one more time and you get 1 1/2 or 3/3.
Answer:
line one should have a y-intercept at (0,2).
Step-by-step explanation:
This simply means that the equation of the line is a horizontal line at the appropriate y value, in this case 49.
F(X) = 49
Y = 49.
Draw a horizontal line on the y axis at the 49th number, basically, the X coordinates of all other points, would vary, but the y coordinate is the same for all of them. As the graph continues.
Domain is all real number
Range is not, it would be 49 only.

example if you had
(x+y)(z+t)
first x times z
outer x time t
inner y times z
last y times t
so
FOIL
(t+2bs^2)(2t-3bs^2)
FIRST (t times 2t=2t^2)
Outer (t times -3bs^2=-3tbs^2)
Inner (2bs^2 times 2t=4tbs^2)
Last (2bs^2 times -3bs^2=-6b^2s^4)
now add
2t^2-3tbs^2+4tbs^2-6b^2s^4
add like terms (-3tbs^2+4tbs^2=1tbs^2=tbs^2)
2t^2+tbs^2-6b^2s^4
