Thirty minutes before a concert, there were 1,200 people in the 3,000-seat auditorium where the concert was being held. Five minutes before the concert, the auditorium was 90% full. Which of these equations can be used to determine p, the number of people who entered the auditorium during this time interval?

Answers

Answer: p = 1500

Step-by-step explanation:

Initially, there were 1200 people.

After the given interval, we know that the auditorium is 90% full (where the auditorium can hold a maximum of 3000 people)

Then after the interval, the number of people in the auditorium is equal to the 90% of 3000.

When we have a percentage X of a quantity A, the quantity of the percentage X is:

N = (X/100%)*A

In this case, the 90% of 3000 is equal to:

N = (90%/100%)*3000 = 0.9*3000 = 2700.

Then, at the beginning of the interval there were 1200 people, and at the end there were 2700.

The difference is:

p = 2700 - 1200 = 1500

This means that the number of people who entered the auditorium dirung the time interval is 1500.

50 pts and brainliest. Is the ratio of arc length to r always equal to pi? What is it equal to?

Please only answer if you know it, this is super important!! If it's right I'll mark you brainliest!

Answers

Answer:

It can sometimes be equal to π. However, it is equal to our central angle.

Step-by-step explanation:

First, recall that arc length is given by:

[tex]s=r\theta[/tex]

Where s is the arc length, r is the radius, and θ is the central angle of the arc in radians.

So, the ratio of the arc length to the radius is:

[tex]\displaystyle \frac{r\theta}{r}[/tex]

The radius r cancels. Hence, we are left with:

[tex]=\theta[/tex]

So, the ratio of the arc length to the radius does not equal π (although it can sometimes if the central angle is π radians (or 180°)). Rather, the ratio is equivalent to the central angle.

So, for example, if we have a circle with radius 7 with a central angle of 3π/2 (this gives us an arc length of 21π/2), then the ratio of the arc length to the radius will be 3π/2 (our central angle).

Answer:

Sometimes it can be equal to π. It is equal to our central angle.

Step-by-step explanation:

Recalling arc length is given by:

Where s is the arc length, r is the radius, and θ is the central angle of the arc in radians.

So, the ratio of the arc length to the radius is:

rθ/θ

The radius r cancels. Hence, we are left with:

= θ

GEW has angle measures given by m/_G=5x + 66, m?/_ E = 3x, and m/_ W= 142 -4x whats the mesure of e

Answers

Answer:

21°

Step-by-step explanation:

GEW has angle measures given by m/_G=5x + 66, m?/_ E = 3x, and m/_ W= 142 -4x whats the mesure of e

= 5x + 66 + 3x + 142 - 4x = 180

4x + 208 = 180

4x = 208 - 180

4x = 28

x = 28/4

x = 7

Solving for E = 3x

E = 3 × 7

E = 21°
