Answer:
Step-by-step explanation:
This only works if the room is a prism shaped, or cylinder.
Volume of a prism or cylinder is area of he base times height. So since we know the height and volume we can fand the area.
V = h*B
B = V/h
B = 400/25
B = 8
This is a very narrow room, anyway, the area of the base, which we want to carpet is 8 square meters. Can you figure out how much it will cost since each square meter will cost 5?
X=2 so the value of x+5 is 7
All you have to do is plug in the given number into the equation
h(x)=3x+1
h(x)=3(-2)+1
h(x)=-6+1
h(x)= -5
Answer: A
Step-by-step explanation:
First route: 70 miles divided by 55 mph = 1.27 hours
Second route: 85 miles divided by 65 mph = 1.31 hours
The first route takes less time so it’s better
