Answer:

C

Step-by-step explanation:

This is because in order to find the area, you need to dfine R^2*PI and half of 12 is 6 so 6*6 is 36 and 36 times 3.14 is 113.04 and since you need to convert it into cal, times that by 22 which is C

You are designing an amusement park ride with cars that will spin in a circle around a center axis, and the cars are located at
Andrei [34K]

Answer:

144 people.

Step-by-step explanation:

Let n be the vertices, where cars are located.

We have been given that the sum of the measures of the angles' vertices is 6120°.

Let us find the number of vertices using formula:

\text{Sum of all interior angles of a polygon with n sides}=180(n-2).

Upon substituting the given sum of the measures of the angles in this formula we will get,

6120=180(n-2)

Using distributive property a(b+c)=a*b+a*c we will get,

6120=180n-360

Adding 360 to both sides of our equation we will get,

6120+360=180n-360+360

6480=180n

Upon dividing both sides of our equation by 180 we will get,

\frac{6480}{180}=\frac{180n}{180}

36=n

As the cars are located on the vertices of regular polygon, so there will be 36 cars in the ride.

We are told that each car holds a maximum of 4 people, so the number of maximum people who can ride at one time will be equal to 4 times 36.

\text{Maximum number of people who can be on the ride at one time}=4\times 36

\text{Maximum number of people who can be on the ride at one time}=144

Therefore, the maximum number of people who can be on the ride at one time is 144 people.

Which table has a constant of proportionality between y and x of 1/5? (from khan academy)
katovenus [111]

Answer:

C

Step-by-step explanation:

Solve for each choice until you get the answer 1/5.

A.

2 - 4/5

10/5 - 4/5 = 6/5; this is not 1/5

B

8 - 8/5

40/5 - 8/5 = 32/5; this is not 1/5

C

3 - 16/5

15/5 - 16/5 = -1/5

5 - 26/5

25/5 - 26/5 = -1/5

7 - 36/5

35/5 - 36/5 = -1/5; although this is negative, it still has the same proportionality of 1/5
