Answer:
66 ft
Step-by-step explanation:
L ∝ n
L = kn , k -> number of sections
Length of 3 sections= 18 ft
3n = 18
n = 18/3
n = 6 ft
Length of 1 section of fence = 6 ft
Length of 11 sections of fence = 6* 11 = 66 ft
Answer: the width of the uniform path is 9 meters.
Step-by-step explanation:
Let x represent the width of the uniform path.
A pool measuring 18 meters by 22 meters is surrounded by a path of uniform width. It means that the combined length of the pool and the uniform path is (18 + 2x) meters and the combined width of the pool and the uniform path is (22 + 2x) meters.
If the area of the pool and the path combined is 1440 square meters, it means that
(18 + 2x)(22 + 2x) = 1440
396 + 36x + 44x + 4x² = 1440
4x² + 80x + 396 - 1440 = 0
4x² + 80x - 1044 = 0
Dividing both sides of the equation by 4, it becomes
x² + 20x - 261 = 0
x² + 29x - 9x - 261 = 0
x(x + 29) - 9(x + 29) = 0
x - 9 = 0 or x + 29 = 0
x = 9 or x = 29
Since the width cannot be negative, then x = 9 meters
Lets figure out the price per oz for reach product. We can do that by dividing the price by the number of oz contained within the product.
Therefore, the smaller 8 oz bottle has the better unit price.
4 is the length missing hope this helped
