a. How many degrees would the Ferris wheel rotate in 100 seconds?
b. How far has a person traveled of he or she has been on the Ferris wheel for 7 minutes?
c. How long would it take for a person to travel 200 feet?
Try to show work :))
Answer:
A) 60 Degrees
B) 550 Feet
C) 2.5 minutes
Step-by-step explanation:
a) So the wheel has completed one revolution in 10 minutes so lets first divide 100 secs with 10 minutes to calculate the the fraction of revolution
1 min = 60 secs
10 min = 600 secs
100/600 = 1/6
One complete revolution is 360 degrees and 1/6 of 360 degrees will be 60 degrees .
360/6 = 60°
b) It takes 10 minutes to complete one revolution so if the person is on it for 7 minutes it would be 7/10 of a revolution . The ferris wheel has a diameter of 250 feet so the radius will be 125 feet because it is the half of the diameter and the circumference will be 250 π . To calculate the distance lets multiple the fraction of the revolution which is 7/10 into the circumference = 550 Feet.
C)It took 10 minutes to travel 250 π now we will use this relation to calculate 200 feet . lets suppose t is for time .
.
After solving this equation as there is only one unknown which is "t "the answer will be 2.5 minutes.
new employees each month. Which equation below can be used to determine the
total, T, number of employees 4 months from now?
A: T = 5e +35
B: T = 35e + 5
C: T = 4e + 5
D: T= 5e + 4
Answer:
C
Step-by-step explanation:
We know that 35 employees are currently at the company and this is constant. If the employees, e, increases by a factor of 5 each month for 4 months. Therefore the equation should be :
The equation only accounts for the employee total increase after 4 months
Answer:c T = 4e + 5

Answer:
Hey! I think that the answer is maybe A, the first one. 1/11 ^12.
Step-by-step explanation:
There's a good website called M A T H W A Y. I really reccomend it if you're trying to figure out how to do something. You just put in the equation, it solves it for you, and even explains why and how it got that answer.
Answer:
11^4
Step-by-step explanation:
13-(-3)
adding the opposites, you get 16 degrees.
-3+13
using a number line: 3 to the left, 13 to the right=10 degrees
For example: 10-(-1)= positive 11. no. you could have -1-(-9). Add the opposites and you get positive 8.
