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.
Jimmy is selling used books at a yard sale. A customer buys 9 books at a cost of $0.75 each and pays with a $20.00 bill. Jimmy must determine c, the amount of change in dollars he should give the customer. Which equation represents c?
20 minus 0.75 c = 9
20 minus 0.75 = 9 c
0.75 (9) + c = 20
0.75 c + 9 = 20
Answer:
c

Answer: immy is selling used books at a yard sale. A customer buys 9 books at a cost of $0.75 each and pays with a $20.00 bill. Jimmy must determine c, the amount of change in dollars he should give the customer. Which equation represents c?
20 minus 0.75 c = 9
20 minus 0.75 = 9 c
0.75 (9) + c = 20
0.75 c + 9 = 20
C / 0.75 (9) + c = 20
Step-by-step explanation:
To find your change, first you must determine how much the customer is paying. To find this, you must multiply the cost of one book by the number of books bought.

I take the distance between two points first.
Then, I divide it by two to get it's half length.
Then, I take the lowest point of the two which is (3,5).
Then, I add 2 to 3 and 4 to 5 which makes it (5,9).
Again, this is how I usually do it. I hope others will also answer your question.
90 kg in the ratio 2:3:7
Answer:
15:22.5:52.5
Step-by-step explanation:
2:3:7=2+3+7=12
90 divided by 12 is 7.5
multiply each factor by 7.5
2-15
3-22.5
7-52.5
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
15 : 22.5 : 52.5

where do i plot the mean point on the graph?
&
draw a line of best fit on the graph
pls help
Answer: Check out the diagram below
=========================================================
Explanation:
I plotted all of the given points in GeoGebra. The point M in blue is the mean point located at (8.44, 400.89)
The purple line is the regression line (aka line of best fit) which is y = 41.098x + 53.843 approximately.
Use of technology is recommended.

The curved surface area of a right circular cylinder of height 14 cm is 88 cm2. find the diameter of the base of the cylinder
Answer:
2 cm
Step-by-step explanation:
h = 14 cm
Curved surface area of a right circular cylinder = 88 cm²
2πrh = 88
[tex]2 * \frac{22}{7}*r*14=88\\\\r = \frac{88*7}{2*22*14}\\\\ r =1 \\\\r = 1 cm[/tex]
Diameter = 2 * r = 2 * 1 = 2 cm

Answer
Your answer is x<3
find the value of x.
Answer:
x = [tex]\sqrt{87}[/tex]
Step-by-step explanation:
if you draw a perpendicular segment from the vertex between sides 5 and 16 to the opposite side then you have a right triangle and can use the Pythagorean Theorem, a² + b² = c²
a = x
b = 13 (you get this from 18 - 5)
c = 16
x² + 13² = 16²
x² + 169 = 256
x² = 87
x = √87

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
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.
