V = 1/3 * 3.14 * 11 * 6^2 = 414.48 m^3
cost = V * 20 = 414.48 * 20 = 8289.60
Answer:
The slope is
Step-by-step explanation:
Take the general equation of a straight line
Here is the slope of the line.
So let's get the equation of the line in the question in the same form.
Add to both sides:
Add to both sides:
Divide by to get it into the general equation:
Now compare it to the general equation to find the value of . The value of is the coefficient of which we can see is
1/4
and 6/4 there we go here is your answer
Answer:
Upstream - 2 miles per hour
Downstream - 3 miles per hour
Step-by-step explanation:
For the speed upstream, the answer would be 2 miles per hour (mph), because 6÷3=2.
For the speed downstream, the answer would be 3 miles per hour (mph), because 6÷2=3.
Both answers come in similar methods. Hope this helps you!
