Answer:

Step-by-step explanation:

Turn

Just turn the percentage into a decimal, in this case turn 20% into the decimal form .20.

Multiply

Multiply the decimal by the dollar.

.20 x 30 = 6$.

This applies to other questions similar to this. Turn the percentage into a decimal.

102% of 50$

102% = 1.02

1.02 x 50 = 51 $

3% of 8$

3% = 0.03

0.03 x 8 = 0.24 $

staircase of steps in a swimming pool has a vertical rise of 14 inches per step and a landing of 20 inches.
Jlenok [28]
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
