30% = 0.3
Since 30% of 90 is 27, the average person uses approximately 27 gallons of water outdoors per day.
Solution:
To write percent to decimal, divide the number by 100.
= 0.3
30% = 0.3
Average use of water each day = 90 gallons
= 27
Since 30% of 90 is 27, the average person uses approximately 27 gallons of water outdoors per day.

Answer:
two real, unequal roots
Step-by-step explanation:
This is a quadratic equation. The quadratic formula can be used to determine how many and what kind of roots may exist:
Find the discriminant, which is defined as b^2 - 4ac, if ax^2 + bx + c = 0. In this case, a = 1, b = -2 and c = -8, so that the discriminant value is
(-2)^2 - 4(1)(-8), or 4 + 32 = 36.
Because the discriminant is real and positive, we know for certain that we have two real, unequal roots
