Answer: Driven gear will have 50 teeth, and driver gear will have 42 teeth
Step-by-step explanation: First we have to know the formula of gear ratio which is started below
(No of teeth on driven)/(No of teeth on driver)
Note: we should all know in the combination of a gear system, we have two gears, the driver gear and the driven gear
So since the least amount of teeth for any gear is 50, we assume the no of teeth on the driven is 50
And no of teeth on the driver is x
50/x = 1.1839323
Cross multiply
x x 1.1839323 = 50
x = 50/1.1839323
x = 42.23
To the nearest whole number = 42
So therefore, number of teeth on the driver gear is 42
Answer:
I think C
Step-by-step explanation:
Since Nancy wants a fence around her backyard, we are obviously talking about perimeter here.
10 + 10 + 15 + 15 = 50
The perimeter of her backyard is 50 meters
50 x 10 = 500
It would cost her $500
