The equation of an arc is given by;

L= xr

where L is the length

x is the angle of facing the arc

r is the radius of the circle

First change the angle from degrees to radians

If 180 degrees is π(3.14159)

then 120 degrees are ?

x=120×3.14159/180

x=2.094

L=2.094×6= 12.566 feet

Can you guys help me?​
kumpel [21]

Answer:

Step-by-step explanation:

1. y = 2x

       y = 2*4 = 8  Checks, therefore

y = 20  for x = 10

2. y = 3x

       y = 3*(0.3) = 0.9  Checks, therefore:

y =  3*(1.5) = 4.5  

       y = 3*

3. y = 5/x

       y = 5/(1/2) = 10  Checks, therefore:

       3 = 5/x

x = 5/3

4 v = wu

7*3 = 21  Checks, therefore:

v =  (3/4)*(6) = (18/4) = (9/2)

v = (2/3)wu

v = (2/3)*7*3 = 14 Checks

5 m = Kn/p  [Add the K as a constant that will make m = Knp true at some value of K]

9 = K*2/(1/3)

27 = (K*2)

27 = 2K

K = (3/2)

       m = (3/2) (n/p)

       m = (3/2)*((1/2)/(1/3))

        m = (3/2)*(3/2)

        m = 1

A coin is tossed, and a standard number cube is rolled. What is the probability that the coin shows heads and the number cube sh
Genrish500 [490]
The correct answer to this question is this one: "C. One-Fourth."

The total possibility that the head and even no on dice appears is 3.

The total possible choices are 12 {head ->(1,2,3,4,5,6) & tail->(1,2,3,4,5,6)}. so the probability is 3/12= 1/4.


These are independent events so the total probability will be the product of the individual probabilities:

The water level in an ocean bay changes at an average rate at 3 meters per hour. at this rate, how many hours would it take for
11Alexandr11 [23.1K]
You can just do 12/3 which = 4.
Broken down you will see,
3m = 1hr
6m = 2hr
9m = 3hr
12m = 4hr
So the answer is 4hours
