How many ounces of pure cranberry juice and how many ounces of a citrus fruit drink containing 14% fruit juice should be mixed to get 172 oz of a fruit drink that is 25% fruit juice?

Let cranberry juice be x.
Let citrus fruit juice be y.

x + y = 630
x + 0.1y = 630*0.23

Solving this yields,

x = 91
y = 539

Therefore, you need 91 oz of pure cranberry juice and 539 oz of fruit juice.

Hope this helps.:)

An obtuse triangle.

Step-by-step explanation:

We have given the different sides of a triangle that is Side A = 2, Side B = 8 and Side C = 7.

According to the question, we can tell the triangle is acute, obtuse or a right triangle.

We know that,    

For given sides x,y,z of a triangle,

If = , then its a right triangle.

If < , then its an acute triangle.

If > , then its an obtuse triangle.

We have a = x = 2, b = z = 8 and c = y = 7.

Note: We always take z as the greatest side length.

Now,

We can see that, 4 + 49 < 64.

So, we can apply rule

if > , then its an obtuse triangle.

Therefore,

Given sides are of an obtuse triangle.
