Answer:
If two angles are not complementary, then their angles add up to 180 degrees.
Step-by-step explanation:
P=2(L+W)
P=364
L=99
sub and find W
364=2(99+W)
divide both sides by 2
182=99+w
subtract 99 from both sides
83=W
w=83ft
Answer:
The y-intercept is (0,-12).
Step-by-step explanation:
Given equation is
.
Now question says to find the y-intercept of the given parabola
.
We know that y-intercept means the y-value when x-value equals 0
so let's plug x=0 into given equation
then solve that for y.




Hence the y-intercept is (0,-12).
An estimate for the number of ducks would be 62.
There were 30 the first day.
The second day, 8 of those 30 were there as well, so we subtract that from the 40 ducks and get 32.
Add 30 and 32 to get our estimate.
