A brand of grape juice that's is 25% grape juice is mixed with another brand that is 75% grape juice. The result is 7 gallons of

garri49 [273]

Answer:

5.6 gallons.

Step-by-step explanation:

If we take x gallons of 25% grape juice then it will contain $\frac{x}{4}$ gallons of pure grape juice.

Again, if we take y gallons of 75% grape juice then it will contain $\frac{3y}{4}$ gallons of pure grape juice.

If we mix them then the total volume will become x + y = 7 gallons ...... (1)

Again the mixture will become 35% juice.

So, $\frac{\frac{x}{4} +\frac{3y}{4} }{x+y} =\frac{35}{100}$

⇒ 0.25x + 0.75y = 0.35x + 0.35y

⇒0.1x = 0.4y

⇒x = 4y........ (2)

Now, solving equations (1) and (2) we get, 5y = 7, ⇒ y = 1.4 gallons

Hence, x = 4y = 5.6 gallons

Therefore, the 25% grape juice was mixed by 5.6 gallons. (Answer)

A parabola with vertex (h, k) and a vertical axis of symmetry is modeled by the equation y - k = a(x - h)2. Determine the vertex

Vilka [71]

Answer:

B. $(?5,8)$

Step-by-step explanation:

We have been given a parabola with vertex (h, k) and a vertical axis of symmetry is modeled by the equation $y-k = a(x-h)^2$ .

We are also given a parabola $y=(x?5)^2+8$ .

Let us convert our given parabola equation in axis of symmetry equation as shown below:

$y=(x?5)^2+8$

$y-8=(x?5)^2+8-8$

$y-8=1(x?5)^2$

Upon comparing our equation with equation $y-k = a(x-h)^2$ , we can see that $h=?5$ and $k=8$ .

Therefore, the vertex of the parabola is $(?5,8)$ and option B is the correct choice.

How to find the surface area of a triangular prism

Artemon [7]

Answer: Surface area of a triangular prism = 2*Area of Base (triangle) + Perimeter of Base (triangle)*Height

Step-by-step explanation: The sum of the areas of all the sides of the triangular prism is equal to the surface area. Thus, if you add all the areas of the sides you will get the surface area. The equation above is a faster way to do it.
