A^2+b^2=c^2 (Pythagoran theorem)

-> 30^2 + length^2 = 78^2
-> length = √6084-900 = <span>√5184 = 72 ft

=> area = length x width = 72 x 30 = 2160 ft^2</span>

OlgaM077 [116]

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.:)
