3 cups for each student implies 3*48=144 cups for 48 students.
1 quarts is equivalent to 4 cups, 144 cups will give 144/4 = 36 quarts.
Ion even know lol ask your teacher
The width of one campsite is 30.5 yards.
The campsite area has a 1220 square yards and a width of 5 yards.
If we divide 1220 by 5, we see that the total length of the campgrounds must be 244 yards.
Now, divide 244 by 8 and you will get that each campground is 30.5 yards wide.
(Unless, you forgot to include the distance of the campground with the given width, that would change our answer)
Answer:
(x)^2 (y)^2
---------- + --------- = 1

Step-by-step explanation:
The standard equation for an ellipse is
(x-h)^2 (y-k)^2
---------- + --------- = 1
a^2 b^2
The center is at (h,k)
The vertices are at (h±a, k)
The foci are at (h±c,k )
Where c is sqrt(a^2 - b^2)
It is centered at the origin so h,k are zero
(x)^2 (y)^2
---------- + --------- = 1
a^2 b^2
The center is at (0,0)
The vertices are at (0±a, 0)
The foci are at (0±c,0 )
The vertices are (±2,0) so a =2
The foci is 1
c = sqrt(a^2 - b^2)
1 = sqrt(2^2 - b^2)
Square each side
1 = 4-b^2
Subtract 4 from each side
1-4 = -b^2
-3 = -b^2
3= b^2
Take the square root
b=sqrt(3)
(x)^2 (y)^2
---------- + --------- = 1
