Answer:
13
Step-by-step explanation:
its 13 calculator
So first you would have to divide overall price by the number of jeans to work out how much one pair would be
Old Navy : $24 ÷ 3 = $8 for 1 pair.
Wet Seal : $16 ÷ 2 = $8 for 1 pair.
Marshalls : $39 ÷ 4 = $9.75 for 1 pair.
The store with the best deal would be either Old Navy or Wet Seal.
Answer:
C) 52 in^3
Step-by-step explanation:
The first is to determine the formula of the volume of the box, which would be the following:
V = height * length * width
Knowing that we have a rectangular piece we will determine the maximum volume, we will double a distance x (which will be the height) in the width and length of the piece, therefore as it is on both sides, the length and width are defined from the Following way:
length = 10 - 2 * x
width = 8 - 2 * x
height = x
Now we calculate the volume:
V = x * (10-2 * x) * (8-2 * x)
To determine the maximum volume we will give values to x in order to see how it behaves:
Let x = 2.5
V = (5) * (3) * (2.5) = 37.5
Let x = 2
V = (6) * (4) * (2) = 48
Let x = 1.5
V = (7) * (5) * (1.5) = 52.5
Let x = 1
V = (8) * (6) * (1) = 48
Let x = 0.5
V = (9) * (7) * (0.5) = 31.5
It can be seen that the greatest volume is obtained when the height is equal to 1.5 and its volume is 52.5 in ^ 3

Answer:
x=18.2
y=21.7
(18,21)
Step-by-step explanation:
−20x + 15y = −40
20x − 8y = 192
7y=152
y=21.7
y=21.7 , -20x+325.5=-40
-20x=-365.5
x=18.2
