Step-by-step explanation:
100ft. / 10ft.
it's is kind of simple
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.

Answer:
490kpa
Step-by-step explanation:
V1 = 70ml and P1 = ? kpa
V2 = 15ml and P2 = 105kpa
if 15ml will give me 105kpa
then how many times is 70ml greater than 15ml
70/15 = 4.6667
then multiply it by 105kpa
4.6667 * 105 = 490kpa
meaning that if 15ml will give me 105kpa
then 70ml which is (15*4.667) will give 490kpa
35 more than 8 times a number
.Let that number be x
35 more than 8 times the number x is written as 35+8x
And 43 less than the product of -7 and the number is written as 43 - -7x
=43+7x
and from the question, the two equations are equal,so we just place the equal sign between the two expression and solve for X
Thus
35+8x=43+7x
Grouping of like terms
8x-7x = 43-35
X = 8 .
