Joel is 13.
Because if the sum of all there ages added together divided by 3, will give you 13.
I think the question for this problem is to find the slope of the staircase. The slope is a ratio of change of the y-coordinates and x-coordinates of points. It is written as Δy/Δx especially in analytical geometry. It could also be simply the ratio of the rise or vertical height to the run or horizontal length.
Therefore, the slope of the stair case is
Slope = rise/run = 14/20 = 0.7
Answer:
result is 20%
Step-by-step explanation:
initially B was 100%
therefore 100% - 40%
=60% remaining
60% - 40%
= 20%
