Answer:
Step-by-step explanation:
Hope this helps.
Height of each floor = 5 meters
time to travel from the first floor to 68th floor = ?
Speed of elevator = 7.5m/s
While an elevator travels from 1st floor to 68th floor, we will multiply the height of floor with 67 to get the distance covered by the elevator form 1st floor to 68th floor, the height of 68th floor will not be counted in the distance because an elevator reaches the 68th floor not covered the height of that floor.
Distance = 5 x 67 = 335m
Now calculate the time by using the formula;
time = distance / speed
= 335m / 7.5m/s
= 44.667 seconds
Thus, an elevator will take 44.667 seconds to reach 68th floor.
So there’s a flat fee of 2 and that’s like a standalone thing so our equation would be
2 + 1.50m
Assuming m = 9, it would be 2 + 13.50
And the two answers are-
A) $15.50
B) 2 + 1.50m
Answer:
1.04 inch
Step-by-step explanation:
Given: Old house has a basement stairways with 7.25 inch vertical riser and 7 inch horizontal treads.
Remember; horizontal treads is known as run in steps.
Now, calculating the slope of the stairways.
Formula: 
Rise= 7.25 inch
Run= 7 inch.
Subtituting the value in the formula
Slope= 
(∵ Round to two decimal)
∴ Slope of stairways is 1.04.
