We now have three equations, so we can solve them.

Let's define the length of the 3 boards in terms of x:

F=x

S=2x-3

T=2

F+S+T =26

x+2x-3+2 =26

3x =26+1=27

x =27/3 = 9 feet for First section

2x-3 =18-3 = 16 feet = Second

2 = Third

9+16+2 = 27

27 is the length of the shortest piece.

L = 2 W
B = L x W = 2 W²
Side Area = 2 W H + 2 L H = 2 H ( W + L ) = 6 H W
V = 2 W² H = 10
H = 5 / W²
Cost = 15 * 2 W² + 9 * 5/W
= 30 W² + 270/ W 
C ` = 60 W - 270 / W² 
= ( 60 W² - 270 ) / W² = 0
60 W² = 270
W ² = 270 : 60
W² = 4.5
W = √ 4.5 = 2.12
Cost (min) = 15 * 2 * 4.5 + 30 / 2.12 = 135 + 14.15 = $149.15
Answer: The cost of materials for the cheapest such container is $149.15.

sp2606 [1]

Answer:

Bottle containing cranberry juice has a greater percent of water.

Step-by-step explanation:

A 60 ounce bottle of grape juice contains 33 ounces of water.

So the percentage of water in the bottle = \frac{\text{Amount of water}}{\text{(Amount of water + juice)}}\times 100

= \frac{33}{60}\times 100

= 55%

Similarly 50 ounces bottle of cranberry juice contains 30 ounces of water.

So the percentage of water in the bottle =  \frac{\text{Amount of water}}{\text{(Amount of water + juice)}}\times 100

= \frac{30}{50}\times 100

= 60%

Therefore, bottle containing cranberry juice has a greater percent of water.
