Answer:20%
Step-by-step explanation: Since 2% of x = 4, that would mean 1% would equal 2. So 2 times 100 equals 200, making 20 10% of 200
The amount of chlorine needed to treat a wimming
pool i directly proportional to the volume of the pool
The constant of proportionality for the relationship is 0.002.
We are provided that amount of chlorine needed is directly proportional to the volume of the pool .
So we can formulate the relation as
C = kV ... (1) ( where C = amount of chlorine ,
k = constant of proportionality
V = volume of the pool )
the sample ratio of chlorine to the the volume of pool , we have :
5 : 2500
10 : 5000
15 : 7500
So taking the first sample value and putting it in eqn (1)
we get
5 = k (2500)
therefore,
k = 5/ 2500
k = 0.002
So the constant of proportionality will be 0.002
Similarly if we take the other values also the constant of proportionality will remain the same.

Answer:
Option (C)
Step-by-step explanation:
To simplify an expression, we can combine like terms. For this expression, there are two pairs of like terms, one-fourth y and five-twelfths y, and the constants negative seventeen and six.
To combine the fractions, we can find the least common denominator, twelve, so we can rewrite the fraction as three-twelfths.
Now combine the like terms to get eight-twelfths y minus eleven, which simplifies to two-thirds y minus eleven.

Identify the vertical asymptotes and horizontal asymptote of each.
Vertical asymptotes is x = -4 and horizontal asymptote is y = 1
What is an Asymptote?
An asymptote is a line that a curve approaches but never touches. A line where the graph of a function converges is known as an asymptote.
There are 3 types of asymptotes.
Horizontal asymptote (HA) - It is a horizontal line and hence its equation is of the form y = k.Vertical asymptote (VA) - It is a vertical line and hence its equation is of the form x = k.Slanting asymptote (Oblique asymptote) - It is a slanting line and hence its equation is of the form y = mx + b.The given expression,
f(x) = (x² - 3x) / (x² + x - 12)
First, find Horizontal asymptote
so,
Horizontal asymptote (y) = (leading coefficient of numerator) / (leading coefficient of denominator)
leading coefficient of numerator = 1
leading coefficient of denominator = 1
y = 1/1
y =1 (Horizontal asymptote)
Now, find Vertical asymptote
so, let's simplify the expression f(x) = (x² - 3x) / (x + x - 12)
f(x) = (x(x - 3) ) / (x² + 4x - 3x - 12)
f(x) = (x(x - 3) ) / (x(x + 4) - 3 (x + 4) )
f(x) = (x(x - 3) ) / ( (x -3) (x + 4) )
f(x) = x / (x + 4)
Now, put the denominator = 0
x + 4 = 0
x = -4 ( Vertical asymptote )
Hence, Vertical asymptotes is x = -4 and horizontal asymptote is y = 1

set y = 10 - x
.5x + .75(10-x) = 6
.5x + 7.5 - .75x = 6
.5x -.75x = 6 - 7.5
-.25x = -1.5
