If the mine winch drum diameter is 6 m, calculate how far the cage will drop for each single rotation of the drum.use formular c
frozen [14]

The cage will drop 18.84m for each single rotation of the drum.

It is given that the diameter of the mine winch, d= 6 m.

We can calculate that how far the cage will drop for each single rotation of the drum by using the formula of the circumference.

Circumference, c = 2πr

where,

r = d/2 (radius of the mine winch)

r = 6/2

⇒ r = 3m

Circumference, c = 2πr

⇒ c = 2π×(3)

⇒ c = 6π

⇒ c = 18.84m

Hence, the cage will drop 18.84m for each single rotation of the drum.

Solve the system of linear equations by substitution. x=16−4y 3x+4y=8
Musya8 [376]

Answer:

Solution: (-4,5)

Step-by-step explanation:

x=16-4y

3x+4y=8

-----

The 1st equation tells you x = 16-4y

---

Substitute that into the 2nd equation

and solve for "y":

3(16-4y)+4y = 8

48 - 12y + 4y = 8

-8y = -40

---

 

y = 5

---

Solve for "x"

x = 16-4y

x = 16-4*5

x = 16-20

x = -4
