Answer: The given statement is false.
Explanation:
In industries water is used for many purposes like washing, cooling, fabricating, diluting etc.
Therefore, huge amount of water is used by industries and also waste water or non-consumptive water is thrown by industries into rivers, sea, lakes etc.
An industry can avoid the unnecessary usage of water in various process so that water can be conserved as water is a precious resource of nature.
Therefore, the statement since 40 percent of industrial water use is non-consumptive, there is little that industry can do to conserve even more water, is false.
The answer isFALSE.
Not true

Explanation:
Answer: D. relatively inexpensive and readily available
Fossil fuels are non-renewable sources of energy these resources formed by the geological processes occurring in the earth. It takes millions of years for their formation. These includes coal, petroleum, and natural gas. Unfortunately, the distribution of these resources is not even in the regions of the world but efforts have been done by the humans to make them available everywhere. They are relatively inexpensive and readily available this contributes to the majority of the world's energy use.
Answer:
After 14 swings, total length = 57.35 feet.
When the child stops swinging, Total length = 60 feet.
Explanation:
The total length of the rope after 14 swings form a geometric progression which is also known as exponential sequence.
The sum of the term in a Geometry progression is
Sₙ = a(1-rⁿ)/1-r.................(1)
Where Sₙ = sum of the nth term, a= first term, n= number of term, r= common ratio.
n=14, a= 12 feet, r=80% = 0.8.
Substituting the values above into equation(1)
S₁₄ = 12(1-0.8¹⁴)/1-0.8
S₁₄= 12(1-0.04398)/1-0.8
S₁₄= 12(0.95602)/0.2
S₁₄ = 11.47/0.2
S₁₄= 57.35 feet
∴ After 14 swings, the total length the rope will swing is = 57.35 feet.
The total length of the rope when the child stop swinging = sum to infinity of the Geometry progression( exponential sequence).
The sum to infinity of an exponential sequence
S = a/1-r
Where a= first term= 12 feet, r= common ratio = 0.8.
∴ S= 12/1-0.8
S= 12/0.2
S = 60 feet
When the boy stops swinging, the total length the rope have swung = 60 feet.
