Answer:
y(x)=0.8x+2.1
x=12 miles
Step-by-step explanation:
Let x represent the number of miles covered and with a fixed charge of 2.1 irrespective of miles covered then the equation can be written as
y(x)=0.8x+2.1
Substituting y(x) with 11.7 then
11.7=0.8x+2.1
0.8x=11.7-2.1=9.6
X=9.6/0.8=12 miles
Answer:
791.28 in^2
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
The diameter is 12 so the radius is 1/2 d = 1/2(12) =6
V = 3.14 (6)^2 * 7
791.28 in^2
