Step-by-step explanation:
one of them is gonna be alot lighter than the rest so i guess use intuition to find it and then measure its weight. ion have a clue what i just said :(
The time taken to get to the 4th can be obtained by dividing the distance given by the speed of the lift.
Distance, height from ground to 4th floor = 42 feets
Time taken to get to the 4th floor = t
Recall :
Time = Distance / speed
- We aren't given the speed of the lift ;
- Assume speed of lift is 7 ft/sec
The time taken to get to the 4th floor will be :
Therefore, to obtain the time taken, divide the distance or height of the 4th floor by the speed of the lift.

Answer:
The theater sold a higher ratio of Senior tickets to Adult tickets on the first night.
Step-by-step explanation:
Rate of senior tickets to adult tickets:
Can also be interpreted as the percentage of senior tickets, out of the number of total tickets, which is the number of senior tickets multiplied by 100% and divided by the number of total tickets.
The first night, 19 Senior tickets and 57 Adult tickets were sold.
19 out of 19 + 57 = 76. So
19*100%/76 = 25%
The second night, 20 Senior tickets and 62 Adult tickets were sold.
20 out of 20 + 62 = 82. So
20*100%/82 = 24.39%
25% > 24.39%, so the theater sold a higher ratio of Senior tickets to Adult tickets on the first night.
Answer:
4 hours
Step-by-step explanation:
Let the number of hours = x.
Jay reads 55 pages per hour, so in x hours, he reads 55x pages.
After reading for x hours, he has 278 - 55x pages left to read.
Odhran reads 45 pages per hour, so in x hours, he reads 45x pages.
After reading for x hours, he has 238 - 45x pages left to read.
Since we want to know when they have the same number of pages left, we set the expressions equal and solve for x.
278 - 55x = 238 - 45x
Add 45x to both sides.
278 - 10x = 238
Subtract 278 from both sides.
-10x = -40
Divide both sides by -10.
x = 4

<h3>
Answer:</h3>
- running speed: 8 mph
- walking speed: 2 mph
<h3>
Step-by-step explanation:</h3>
Let w represent Lizette's walking speed. Then her running speed is w+6. The relationship between speed, time, and distance is ...
distance = speed × time
Lizette ran for 1.5 hours, then walked for 3 hours. Her total distance is ...
(w+6)·1.5 + w·3 = 18
4.5w + 9 = 18 . . . . . simplify
4.5w = 9 . . . . . . . . . subtract 9
w = 2 . . . . . . . . . . . .divide by 4.5
Lizette's walking speed is 2 mph; her running speed is 8 mph.
