Answer:
54.514 rev/min
Step-by-step explanation:
Data provided in the question:
Speed of the cable car = 12.65 miles per hour
Diameter of the rotating wheel, d = 6.5 feet
Now,
The speed of rotation of the wheel will be equal to the speed of the cable car
thus,
The speed of rotation of the wheel = 12.65 miles per hour
also,
1 miles = 5280 feets
1 hour = 60 minutes
Thus,
The speed of rotation of the wheel =
= 1113.2 ft/ min
Circumference of the wheel = πd
= 6.5π feet
= 20.42 feet
Therefore,
The speed of rotation of the wheel in revolutions per minute
= 1113.2 ÷ 20.42 rev/min
= 54.514 rev/min
Answer:
x=-3
Step-by-step explanation:
6x - 2 =7x +1
6x - 7x =1+2
-x=3
x=-3
6x - 6x - 2=7x - 6x +1
0-2=x+1
-2=x+1
x=-2-1
x=-3

Step-by-step explanation:
Answer: Surface Area = 16in.
Step-by-step explanation:
So we need to find the area of each side and add them up.
First we find the area of one of the triangular sides: 2*3/2 = 3
Then we multiply it by 4 to accommodate the 4 sides that are the same size: 12
Then we do 2*2 = 4 for the base. We then add those up.
4 + 12 = 16
