Answer: The slope of the ant hill is 18/20 or 0.9.
For the slope, we need to put the vertical change over the horizontal change. In this case, the vertical change of the ant hill is 18.
Now for the horizontal change, the entire base is 40. However, we only need half of that because we need the distance from the outside to the middle where the height is. Half of 40 is 20.
Therefore, the slope is up 18 over 20. Or 18/20 = 0.9.
Step-by-step explanation: You know that 18 is the height and 40 is the base, so put 18 over 40. Since you only need to know the base from the end to the middle, you need half which is 20. Thus, the answer is 18 over 40.
