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

- Draw a line in between each of those flowers.
- Count up all those flowers!
Answer:
- 132
Step-by-step explanation:
This can be evaluated without a calculator.
Take each part of the calculation and evaluate, that is
- 6(3)(- 4) = - 6 × - 12 = 72
3(3)²(- 4) = 3 × 9 × - 4 = - 12 × 9 = - 108
2(3)(- 4)² = 6 × 16 = 96
Putting the 3 parts back together
72 - 108 - 96
= 72 - 204
= - 132
