Answer:The diameter of the Ferris wheel in the image is 63 feet, and so the circumference is equal to C=πd=63π C = π d = 63 π feet. So the distance traveled in one ride (12 revolutions) is 12C=12⋅63π=756π≈2375.044 12 C = 12 ⋅ 63 π = 756 π ≈ 2375.044 feet.

Answer:
15
Step-by-step explanation:
(whole secant) x (external part) = (tangent)^2
(5+x) * 5 = 10^2
Distribute
25 +5x = 100
Subtract 25 from each side
25-25 +5x = 100-25
5x= 75
Divide by 5
5x/5 = 75/5
x = 15
Answer:
240 hours
Step-by-step explanation:
One person hour is a unit indicating the rate at which one person is working on the project .
The company estimates that it will take 2880 person- hours to complete the job
So let's determine how many hours it will take 12 workers to complete same job
The rate = 2880 person/hour
12 persons or workers =( 2880 person/hour)/12 persons
12 persons or workers = 2880/12
12 persons or workers=240 hours
It will take 12 workers 240 person hour to finish the project.
