Question

The equation Q=100-2F represents the quantity of available water (Q) in a region in millions of gallons, where Fis the number of fracking sites in the area. If there are 25 fracking sites, what is the quantity of available water? (1 point)
• 75 million gallons
• 60 million gallons
• 90 million gallons
• 50 million gallons
What would farm productivity plummet without?
Select the TWO correct answers.
(1 point)
• energy.
• water
• food
• biodiversity

Answer 1

To find the quantity of available water (Q) when there are 25 fracking sites (F), we can substitute F=25 into the equation Q=100-2F.

Q = 100 - 2(25)
Q = 100 - 50
Q = 50 million gallons

So, the quantity of available water is **50 million gallons**.

For the second part, farm productivity would plummet without **water** and **energy**.

So the correct answers are:
- water
- energy
