Water in the swimming pool initially = 2.5 million liters
Water in the swimming pool after evaporation = 2 million liters
Therefore, volume of water evaporated = 2.5 million liters - 2 million liters
=0.5 million liters
To find the percent of water evaporated, divide the volume of water evaporated by the volume of water in the swimming pool initially and then multiply it by 100.
Percent of water evaporated =( 0.5 / 2.5) x 100 =20%
Answer:
x = 7 x= -2
Step-by-step explanation:
x^2 -5x -14 =0
What 2 numbers multiply to -14 and add to -5
-7*2 = -15
-7 +2 = -5
(x-7) (x+2) =0
Using the zero product property
x-7 =0 x+2 = 0
x = 7 x= -2
5600 is 100 times larger than 56.
