Answer:
Amount of vinegar. 100% : 20 milliliters
Amount of Italian dressing: 140 milliliters
Step-by-step explanation:
Let's call A the amount of vinegar. 100%
Let's call B the amount of Italian dressing . 12% vinegar
The resulting mixture should have 23% vinegar, and 160 milliliters.
Then we know that the total amount of mixture will be:
Then the total amount of pure antifreeze in the mixture will be:
Then we have two equations and two unknowns so we solve the system of equations. Multiply the first equation by -1 and add it to the second equation:
+
--------------------------------------
We substitute the value of B into one of the two equations and solve for A.
Answer:
The answer to your question is below
Step-by-step explanation:
Data
Center = (0, 0)
Vertex = (13, 0)
Focus = (12, 0)
Process
From the data we know that it is a horizontal ellipse.
1.- Calculate "a", the distance from the center to the vertex.
a = 13
2.- Calculate "c", the distance from the center to the focus
c = 12
3.- Calculate b
Use the Pythagorean theorem to find it
a² = b² + c²
-Solve for b
b² = a² - c²
-Substitution
b² = 13² - 12²
-Simplification
b² = 169 - 144
b² = 25
b = 5
4.- Find the equation of the ellipse
or 
Horse- 50l
sheep-4l
chicken-200ml
first you have to convert all the symbols into one, so we'll convert liters into milliliters,
1000ml=1l
horse= 50 ×1000=50000ml
sheep=4×1000=4000ml
chicken= 200ml
so now we have to multiply them by the number of animals,
h=50000ml×3=150000ml
s=4000×15=60000ml
c=200×12=2400ml
now add them together,
150000+60000+2400=212400ml
convert it into litres,
212400÷1000=212.4l
answer= 212.4 l
