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.
Given:
A figure that contains a right triangular prism and cuboid.
To find:
The volume of the figure.
Solution:
The dimensions of cuboid are 16 in, 7 in and 3 in.
So, the volume of the cuboid is:



The base of the prism is a right angle with base 3 in and height 5 in, and the length of the prism is 6 in. So, the base are of the prism is



The volume of a prism is:

Where, B is the base area and h is the height of the prism.


The volume of combined figure is:



Therefore, the volume of the figure is 381 cubic in.
Responder:
Pantalón = 50 €
Zapatos = 76 €
Explicación paso a paso:
Total pagado por pantalón y zapatos = 126
Sea el precio del pantalón = p; zapatos = s
p + s = 126
1,14 p = 0,75 s
p = 0,75 s / 1,14
0,75 s / 1,14 + s = 126
(0,75 s + 1,14 s) / 1,14 = 126
0,75 s + 1,14 s = 143,64
1,89 s = 143,64
s = 143,64 / 1,89
s = 76
p + s = 126
P = 126 - s
P = 126 - 76
p = 50
