one or more functions ? i think lol
The linear speed of one of the cars is 7.75 feet per second
The cars (seats) of a Ferris wheel are positioned 74 feet from its center.
The radius, r = 74 feet
The Ferris wheel makes 4 revolutions every 4 minutes
Number of revolutions per minute = 1
Angular speed, w = 1 rev/min
Angular speed, w = 0.10472 rad/sec
The relationship between the linear speed (v), and the angular speed (w) is:
v = wr
Substitute w = 0.10472 and r = 74 feet into the formula:
v = 0.10472 x 74
v = 7.75 feet per second
The linear speed of one of the cars is 7.75 feet per second

Answer: Jim can lay 25 tiles per hour.
Step-by-step explanation:
Let be "x" Jim's rate and "y" Pete's rate.
We know that Jim completed half the floor in 4 hours, then:
![4x](https://tex.z-dn.net/?f=4x)
And Pete completed the other half of the floor in 2 hours, then:
![2y](https://tex.z-dn.net/?f=2y)
Since Jim completed half the floor and Pete completed the other half:
[Equation 1]
We also know that Pete can lay 25 more tiles per hour than Jim, then:
[Equation 2]
Then, we can substitute Equation 2 into Equation 1 and solve for "x":
![4x=2(x+25)\\\\4x=2x+50\\\\4x-2x=50\\\\x=\frac{50}{2}\\\\x=25](https://tex.z-dn.net/?f=4x%3D2%28x%2B25%29%5C%5C%5C%5C4x%3D2x%2B50%5C%5C%5C%5C4x-2x%3D50%5C%5C%5C%5Cx%3D%5Cfrac%7B50%7D%7B2%7D%5C%5C%5C%5Cx%3D25)
Therefore, Jim can lay 25 tiles per hour.
The answer might be 4,245because 14x3=42 & 5x9=45 there is ur answer
