Answer: 
Step-by-step explanation:
Since you indicate that it is a cone, you need to use the formula for calculate the volume of a cone. This is:
Where "r" is the radius and "h" is the height of the cone.
According to the information given in the exercise, the height and the radius of the pylons are the following:
Then, knowing these values, you can substitute them into the formula,as following:
Finally, evaluating, you get that the volume of concrete that Tobias will need for each pylon is the one shown below:
(2,12). Moving left to right is the x, moving up and down is the y.
Answer:
x=403
Step-by-step explanation:
move all the terms that don't contain x to the right side and solve
Answer:
4.
Step-by-step explanation:
First, you have to decide whether the slope is negative or positive. Since the line is going diagonally upward, it is positive.
That means the answer has to be either 3 or 4.
Next, you have to decide whether the y-intercept is negative or positive, on the graph, you can see that it is positive.
Answer choice 4 is the only equation where both the slope and the y-intercept are positive, so it is the answer.
It's 20. You start with the parentheses and 8 + 12 is 20. Then you have the brackets next, and so that's 20/4 and that's 5. Then all you have left is 4 x 5 which is 20.
