Scarcity, specially of water, has always been a problem. But now, the way we consume water in the XXI century is outrageous. Because not only do we consume water, but we pollute the water we have left and waste the water that is still usable.

Answer:
6
Step-by-step explanation:
The hypotenuse will always be equal to "c." You can put "a" or "b" as 8. This gives us a^2 + 8^2 = 10^2 which simplifies to a^2 + 64 = 100. From there, you simplify (subtract 64, giving you a^2 = 36, and then take the square root of a^2 & 36 to get a = 6 (because 6*6 = 36))
(-5, 2, 4, 7)
0 8 -5 3
The co-ordinates are just rewritten in form of a column vector. This gives a matrix of order <span>2x4</span>
1/3b = 4/5
Do the cross multiplication
1(5) = 3b(4)
5=12b
<span>b=5/12</span>
