Answer:
percent* base = amount
.2 * x = 1.80
x = 1.80/.2
x= $9

The slope of a  horizontal line will have a value equal to 0:  
m=0
Point-slope form of a line: we need a point (x₀,y₀) and the slope "m".
y-y₀=m(x-x₀)
We have a point ( E(3,-4) ) and the slope of this line (m=0); therefore:y
y+4=0(x-3=
y+4=0
y=-4
Answer: the equation for the horizontal line that contains the point E, would be:
y=-4
        
             
        
        
        
Answer:
Step-by-step explanation:
The formula for the volume of a cylinder is V = πr²h.  
Here, r = 5cm, and h = 15 cm, and so the volume is:
V = πr²h = π(5 cm)²(15 cm), or:
V = π(25 cm²)(15 cm) = 375π cm³, or approximately 1170 cm³
