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 1

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.

please mark as brainliest!!<3

Answer:

15 : 22.5 : 52.5

Step-by-step explanation:

2+3+7 = 12units

To find how much kg one unit is.

90kg ÷ 12units = 7.5kg/unit

2units : 7.5 x 2 = 15kg

3units : 7.5 x 3 = 22.5kg OR 22/1/2 kg

7units : 7.5 x 7 = 52.5kg OR 52/1/2 kg

Therefore, the answer is

Answers

Answer:

4(y+2) = 3(x+4) and 4y - 3x = 4

Step-by-step explanation:

The equation of the line in point slope form is expressed as;

y - y0 = m(x-x0)

m is the slope

(x0, y0) is the point on the line

Given the equation 3x - 4y = 7

Rewrite in slope intercept form

-4y = -3x+7

y = 3/4 x - 7/4

Slope = 3/4

Slope of the required line will also be 3/4  since they are parallel lines

Substitute the slope and the point into the equation above;

y - y0 = m(x-x0)

y +2 = 3/4 (x+4)

4(y+2) = 3(x+4)

4y + 8 = 3x+12

4y - 3x = 12-8

4y - 3x = 4

Hence the required equations are 4(y+2) = 3(x+4) and 4y - 3x = 4

The table below shows all of the possible outcomes for rolling two six-sided number cubes. A table with 36 possible outcomes. There are 9 desired outcomes. What is the probability of rolling an even number first and an odd number second?
StartFraction 1 over 9 EndFraction
StartFraction 1 over 6 EndFraction
One-fourth
One-half

Answers

The image is missing, we have attached the image.

Answer: The of getting an even number in first and an odd number second is 1/4 or 0.25

Step-by-step explanation:

Given,

Total number of outcomes = 36

We have to find the probability of rolling an even number first and an odd number second.

Solution,

Firstly we will find out the possible outcomes;

(2,1)(2,3)(2,5)(4,1)(4,3)(4,5)(6,1)(6,3)(6,5)

So the total number of outcomes = 9

Now according to the formula of probability, which is;

P(E)= total number of possible outcomes/total number of outcomes

Now on putting the values, we get;

P(of getting an even number in first and an odd number second)= 9/36 = 1/4 =0.25

Hence The of getting an even number in first and an odd number second is

1/4 or 0.25.
