Answer:
Step-by-step explanation:
The foci are horizontally aligned.
horizontal ellipse:
(x-h)²/a² + (y-k)²/b² = 1
center (h,k)
vertices (h±a,k)
length of minor axis = 2b
foci (h±c,k), c² = a²-b²
Apply your data and solve for h, k, a, and b.
foci (±3√19, 6)
h = 0
k = 6
Length of minor axis = 2b = 10
b = 5
foci (h±3√19, 6)
c = 3√19
c³ = a² - b²
171 = a² - 25
a² = 196
x²/196 + (y-6)²/25 = 1

Given:
Gisselle has 1/2 of a candy bar.
She role off 1/2 of what she had and split it into three equal pieces.
Question asked:
What fraction of a candy bar was each piece?
Solution:
Gisselle has = 
She role off = 

As she split it into three equal pieces, we will divided it by 3, we get,


Therefore, fraction of a candy bar of each piece is
