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.

PLEASE TRY TO HELP I'M STRUGGLING
Anvisha [2.4K]

Answer:

Step-by-step explanation:

The equation of a straight line can be represented in the slope intercept form as

y = mx + c

Where

m = slope = (change in the value of y in the y axis) / (change in the value of x in the x axis)

The equation of the given line is

7x+4y=3

4y = - 7x + 3

y = -7x/4 + 3/4

Comparing with the slope intercept form, slope = -7/4

If the line passing through the given point is perpendicular to the given line, it means that its slope is the negative reciprocal of the slope of the given line.

Therefore, the slope of the line passing through (6,-9) is 4/7

To determine the intercept, we would substitute m = 4/7, x = 6 and y = -9 into y = mx + c. It becomes

- 9 = 4/7×6 + c = 24/7 + c

c = - 9 - 24/7 = -87/7

The equation becomes

y = 4x/7 - 87/7
