The rectangular piece of property measures 8 mi by 6 mi. find an equation for the ellipse if the path is to touch the center of
Artyom0805 [142]
The ellipse will be inscribed in the rectangle.
Because the rectangle measures 8 mi by 6 mi, the ellipse has
a = 8/2 = 4 mi (major axis)
b = 6/2 = 3 mi (minor axis)

The equation for the ellipse is
x^2/a^2 + y^2/b^2 = 1

That is
x^2/4^2 + y^2/3^2 = 1
x^2/16 + y^2/9 = 1

Answer:
x^2/16 + y^2/9 = 1

20 liters of mixture contain milk nad water in the ratio 5:3 of 4 liters of the mixture are replaced by 4 liters of milk find th
pantera1 [17]

Answer:

7:3

Step-by-step explanation:

5 + 3 = 8

The ratio is

5 milk : 3 water : 8 total

Milk is 5/8 of the total.

Water is 3/8 of the total.

The 20-liter mixture contains:

5/8 * 20 = 12.5 liters of milk, and

3/8 * 20 = 7.5 liters of water

4 liters of the mixture contain:

5/8 * 4 = 2.5 liters of milk, and

3/8 * 4 = 1.5 liter of water

When you remove 4 liters of the mixture from 20 liters of the mixture, you end up with

12.5 L - 2.5 L = 10 L milk, and

7.5 L - 1.5 L = 6 L water

Now you add 4 liters of milk. Now you have

10 L + 4 L = 14 L milk

6 L water

The new ratio of milk to water is 14:6 = 7:3
