Answer:
y = 2/5x - 1
Step-by-step explanation:
There are a couple of different ways to figure this out, but since you have a graph, the fastest way is to count the slope, or m in the formula, by counting the rise (units up) over run (units to the right), which is 2/5. Then, find the value of b by finding the y-intercept on the graph, or -1.
Answer:
36 cans for $3.32
Step-by-step explanation:
36 cans = $3.32
1 can =$ 0.092
9 cans = $0.91
1 can = $0.01
0.09 and 0.1 the cheaper is 0.09 dollars so 36 cans for $3.32 is better
The volume of the pipe is about 282.6 cubic feet.
First, we need to find the area of each circular cross section and subtract them to find the width of the pipe. The area of a circle is pi(r^2).
pi(3^2) - pi(2^2)
28.26 - 12.56 = 15.7
The width of the pipe is 15.7. Now, multiply that by 18 to find the volume.
15.7 x 18 = 282.6
