Answer:

see explanation

Step-by-step explanation:

For the ellipse

\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1

Then the vertices are (a, 0), (- a, 0) and (0, b), (0, - b)

Given

\frac{y^2}{100} + \frac{x^2}{4} = 1

Then

a² = 4 ⇒ a = 2 and b² = 100 ⇒ b = 10

Hence the vertices are

(2, 0), (- 2, 0) and (0, 10), (0, - 10)

the equation y equals 0.25 x describes a proportional relationship between X and Y what is the constant of proportionality
Fittoniya [83]
The constant of proportionality is for every 1 x, there is 0.25 y. y = 0.25, and on a graph, x is always the "1." Since x is worth 1, y must be worth 0.25.

Carl bought 19 apples of 2 different varieties to make a pie.The total cost of the apple was $5.10.Granny Smith apples cost $0.2
disa [49]

For this case we propose a system of equations:

x: Let the variable representing the quantity of Granny Smith apples

y: Let the variable representing the number of Gala apples

According to the statement we have:

x + y = 19\\0.25x + 0.30y = 5.10

From the first equation we have to:

x = 19-y

replacing in the second equation:

0.25 (19-y) + 0.30y = 5.10\\4.75-0.25y + 0.30y = 5.10\\4.75 + 0.05y = 5.10\\0.05y = 5.10-4.75\\0.05y = 0.35\\y = \frac {0.35} {0.05}\\y = 7

So, Carl bought 7 Gala apples

On the other hand:

x = 19-7 = 12

So, Carl bought 12 Granny Smith apples

Answer:

Carl bought 7 Gala apples and 12 Granny Smith apples
