The linear speed of a person on this Ferris wheel is about 628.2 ft/min.
<h3>What is Linear Speed ?</h3>
As a body travels a circular path, it has both a linear speed and an angular speed. The rate it travels on that path is the linear speed, and the rate it turns around the center of that path is the angular speed. The linear speed (v) and angular speed (ω) are related by the radius (r) or v = rω .
Given that ;
Radius = r = 50 ft
Frequency = f = 2 rev/min
The angular speed is the product of the angular displacement for one complete turn, namely 2π radians per revolution, and the frequency (f). That is, the angular speed is equal to ω = 2πf. Substituting this into the formula for linear speed (v), we get:
v = r (2πf)
= (50 ft) ( 2π / rev) ( 2 rev/min)
= 200π ft/min
≈ 628.2 ft/min
The linear speed of a person on this Ferris wheel is about 628.2 ft/min.

Answer:
13 ounces
Step-by-step explanation:
First we find what 30% of 10 ounces is.
0.3*10 ounces=3 ounces
We add the answer to the original 10 ounces and we get 13 ounces.
Hope that is clear and good luck with homework
Hey there! I'm happy to help!
Let's call our fraction x.
x=5.2727272727......
We want to get rid of the repeating decimals. If we multiply our fraction by 100, we have that 100x=527.27272727.....
100x=527.2727272727....
x=5.27272727....
If we subtract these equations, the repeating stuff will be gone and we can solve for x.
99x=522
We divide both sides by 99.
x=522/99= 58/11= 5 3/11.
Have a wonderful day! :D
