The average number of people at a concert over 3 nights is 125. On the first night, there were 151 people at the concert. The same number of people attended the second and third night. How many people attended on each of the second and third nights?
Answer:
164 people
Step-by-step explanation:
Let's say x = # of people in night 2 and 3
Average = (n₁ + n₂ + n₃ + ...)/n
Plug in known numbers: (125 + x + x)/3 = 151
Multiply + simplify: 125 + 2x = 453
Subtract: 2x = 328
Divide: x = 164
Final answer:
To determine the number of people who attended the concert on the second and third nights, an equation based on the average attendance was formulated and solved, resulting in 112 people attending each of those nights.
Explanation:
To solve this problem, we need to find out how many people attended the concert on the second and third nights. Since we know the average number of people for the 3 nights was 125 and there were 151 people on the first night, we can set up an equation to find the number attending on the other nights.
Let the number of people who attended on the second and third nights be x each. The total number of people over the three nights is then 151 + x + x (since the same number of people attended the second and third nights). To find this number, we multiply the average number of people (125) by the number of nights (3).
We get the equation:
125 * 3 = 151 + x + x
375 = 151 + 2x
375 - 151 = 2x
224 = 2x
x = 112
Thus, 112 people attended the concert on each of the second and third nights.
Terri has 5 boxes of flower seeds. She wants to give the seeds away to friends. If she gives 1/8 of a box away how many people can she give seeds to?
Answer:
She can give 1/8 of a box to 40 people
5x8=40
Step-by-step explanation:
Terri can give seeds to 40 people, each receiving 1/8 of a box, as she has a total of 40 portions of 1/8 from her 5 boxes of flower seeds.
Terri has 5 boxes of flower seeds and wants to know how many people she can give seeds to if she gives away 1/8 of a box to each person. To solve this, we calculate the total portions of seeds she has and then divide that by the portions she is giving to each friend. Since there are 8 portions of 1/8 in one box, Terri has a total of 5 boxes imes 8 = 40 portions of seeds. Hence, Terri can give seeds to 40 people, with each person receiving 1/8 of a box.

Answer:
31. (a) The height decreases by 12 feet each second towards the first floor
(b)
After 3 seconds, the elevator is 144 feet above the first floorAfter 6 seconds, the elevator is 108 feet above the first floorAfter 9 seconds, the elevator is 72 feet above the first floor(c) It takes 15 seconds for the elevator to get to the first floor
(d) The basement floor is 48 feet below the first floor
Step-by-step explanation:
31 (a) explanation:
An elevator is 180 feet above the first floor.
Each second, it descends 12 feet.
So the elevator's change in height each second is a decrease of 12 feet towards the first floor.
31 (b) explanation:
If the elevator goes down 12 feet, towards the first floor, in 1 second then;
After 3 seconds it will be 180 feet - 3(12) feet = 144 feet above the first floorAfter 6 seconds it will be 180 feet - 6(12) feet = 108 feet above the first floorAfter 9 seconds it will be 180 feet - 9(12) feet = 72 feet above the first floor31 (c) explanation:
If the elevator is 180 feet above the first floor and it takes 1 second to descend 12 feet,
Then it will take: [tex]\frac{180 feet}{12 feet}[/tex] × 1 second = 15 seconds reach the first floor.
31 (d) explanation:
From the first floor it takes 4 seconds to reach the basement floor
Therefore the basement floor is [tex]\frac{4 seconds}{1 second}[/tex] × 12 feet = 48 feet below the first floor
The integer -12 is the change in the height of the elevator per second
It will take 15 seconds for the elevator to get to the first floor.
The height of the basement floor with respect to the first floor is 48 feet.
What integer is the change in the height of the elevator each second?Since the elevator descends, the change in height is negative.
The magnitude of the change in height is 12 feet per second, so the change in height is −12 feet per second.
Completing the table.The completed table is
Time Height
0 sec 180
3 sec 180-3*12=132
6 sec 180-6*12=108
9 sec 180-9*12=72
Seconds it takes the elevator to get to the Height first floor.Here, we divide the initial height by the rate of descent.
So, we have
Time = 180 feet / 12 feet per second = 15 seconds.
What is the height of the basement floor with respect to the first floor?If the elevator descends to the basement floor in 4 seconds, then the height of the basement floor with respect to the first floor is
4 seconds * 12 feet per second = 48 feet.

What is the value of b in this diagam?
Answer:
b = 8
Step-by-step explanation:
Given : A triangle with side a= 12 , b = 6.33 and angles.
To find : What is the value of b in this diagam.
Solution : We have given that side a= 12 , b = 6.33
Angle A = 113.17
Angle B = 37.81 .
By the sin law: [tex]\frac{b}{sin B} =\frac{a}{sin A}[/tex].
[tex]\frac{b}{sin( 37.81)} =\frac{12}{sin( 113.17)}[/tex].
[tex]\frac{b}{0.613} =\frac{12}{0.919}[/tex].
On cross multiplication
b * 0.919 = 12 * 0.613 .
b * 0.919 = 7 .356
On dividing by 0.919
b = 8.004
Therefore, b = 8.

The graph shows the total cost (y) of producing x motorbike engines.
Complete the following sentences based on the graph.
The equation of the line is y = .
The total cost of producing 50 engines is .
option 1
0.2x+2
0.25x+2
0.4x+2
1.2x+2
option 2
$12,250
$14,750
$14,500
$15,000
Answer:
1) Second option: [tex]y=0.25x+2[/tex]
2) Third option: $14,500
Step-by-step explanation:
1) The equation of the line in Slope-intercept form is:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept.
You know the point (20,7) of the line and you can observe in the graph that the y-intercept is:
[tex]b=2[/tex]
Then, you can substitute these values into the equation [tex]y=mx+b[/tex]
and solve for the slope "m":
[tex]7=m(20)+2\\\\7-2=20m\\\\m=\frac{5}{20}\\\\m=0.25[/tex]
Therefore, the equation of this line is:
[tex]y=0.25x+2[/tex]
2) To calculate the total cost of producing 50 engines, you need to substitute [tex]x=50[/tex] into the equation of the line [tex]y=0.25x+2[/tex]. Then you get:
[tex]y=0.25(50)+2[/tex]
[tex]y=0.25x+2[/tex]
[tex]y=14.5[/tex]
Since the y-axis represents the total cost "y" in thousands of dollar, then the total cost of producing 50 engines is:

Write the correct comparison (< = > or =) in each box
2...bigger =3/5 less 1/8
To write the correct comparison symbol, we compare two numbers or expressions to determine their relationship, using <, >, or =. This mathematical skill is important for understanding and working with inequalities.
Explanation:To answer a question that asks you to write the correct comparison (using <, >, or =), we need to evaluate and compare the given numbers or expressions to determine which symbol is appropriate. This involves mathematical understanding and skills such as ordering numbers, understanding inequalities, and applying mathematical operations if needed.
Let's use an example to illustrate this:
If we have the numbers 7 and 10, and we are asked to put the correct comparison symbol between them, we would write 7 < 10, because 7 is less than 10.For expressions, if we have 2 + 3 and 4 + 1, the comparison would be 5 = 5, because both expressions equal 5.Writing the correct comparisons is an essential math skill that helps students understand and work with inequalities and is widely applicable in various aspects of both academics and real life.

if a wheelie chair is pushed down the 6th grade hallway and does not bump into any people or lockers, what causes the wheelie chair to stop moving? hurry i need an answer!!
Potential Energy: the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.Compare with kinetic energy
Friction :the action of one surface or object rubbing against another.
plz dont sue me if Im wrong
The wheelie chair stops moving because of friction between the chair wheels and the floor, along with a bit of air resistance. These forces oppose the motion and gradually slow the chair down until it stops.
Even though you initially give the chair energy to move by pushing it, the floor exerts a frictional force that slows it down over time until it comes to a stop.Additionally, air resistance, although minimal, also contributes by creating a small opposing force against the motion of the chair. Together, these forces cause the chair to gradually decrease its speed.Which are the independent events? Check all that apply
Answer:
Independent events are those that do not depend on others. Two entities does not depend on each other. The change in one entity does not change the other.

Answer:
1 cupcake = $3.75
1 ice-cream = $4.50
1 doughnut = $1.50
Step-by-step explanation:
2 ice-cream + 1 cup cake = $12.75 ------------ [ 1 ]
1 ice-cream + 2 doughnuts = $7.50 ------------ [ 2 ]
1 cup cake + 1 doughnut + 1 ice-cream = $9.75 ------------ [ 3 ]
From [ 1 ] :
2 ice-cream + 1 cup cake = $12.75
1 cupcake = $12.75 - 2 ice-cream
Substitute [ 1 ] into [ 3 ]:
1 cup cake + 1 doughnut + 1 ice-cream = $9.75
$12.75 - 2 ice-cream + 1 doughnut + 1 ice-cream = $9.75
1 doughnut - 1 ice-cream = -$3 ------------ [ 4 ]
[ 2 ] + [ 4 ] :
3 doughnuts = $4.75
1 doughnut = $1.50
Substitute (1 doughnut = $1.50) into [ 2] :
1 ice-cream + 2 doughnuts = $7.50
1 ice-cream + 2 x $1.50 = $7.50
1 ice-cream + $3 = $7.50
1 ice-cream = $4.50
Substitute (1 ice-cream = $4.50) into [ 1 ]:
2 ice-cream + 1 cup cake = $12.75
2 x $4.50 + 1 cup cake = $12.75
1 cupcake = $12.75 - $9
1 cupcake = $3.75
To find the cost of each in a system of equations, you need to solve the equations simultaneously. You can solve for one variable first and substitute it into the other equation to find the value of the second variable. Once you have the value of one variable, you can substitute it back into one of the original equations to find the value of the other variable.
Explanation:In the field of Mathematics, specifically in algebra, a system of equations is a set of equations with the same variables. When you're asked to find the cost of each one, you're actually being asked to solve this system of equations. Let's assume your system of equations is:
5x + 2y = 40 (Equation 1) 3x + 4y = 35 (Equation 2)
You can solve for one variable first from either equation and substitute it into the other. For example, from Equation 1 you can solve for x: x = (40 - 2y)/5. Substituting x into Equation 2 gives us: 3((40 - 2y)/5) + 4y = 35. Solving this will give you the value of y which can then be substituted into any of the original equations to find the cost of x.

Given that (9,-8) is on the graph of f(x), find the corresponding point for the function f(3/4x)
Answer:
The corresponding point for the function f(3/4 x) is (12 , -8)
Step-by-step explanation:
* Lets revise the horizontal stretch or compress
- A horizontal stretching is the stretching of the graph away from
the y-axis
- A horizontal compression is the squeezing of the graph toward
the y-axis.
# if k > 1, the graph of y = f(k•x) is the graph of f(x) horizontally
compressed by dividing each of its x-coordinates by k.
# if 0 < k < 1 (a fraction), the graph y = f(k·x) is the graph of f(x)
horizontally stretched by dividing each of its x-coordinates by k.
* Now lets solve the problem
- The function f(x) will be the function f(3/4 x)
∵ The x multiplied by a constant
∴ f(x) stretched or compressed horizontally
∵ f(x) ⇒ f(k · x)
∵ f(x) ⇒ f(3/4 x)
∴ k = 3/4 ⇒ less than 1
∵ 0 < k < 1
∴ f(x) starched horizontally
∴ Divide each of its x-coordinates by k
∵ k = 3/4
∴ Divide each of its x-coordinates by 3/4
∵ Point (9 , -8) is on the graph of f(x)
- Find the corresponding point on the graph f(3/4 x) by dividing
x-coordinate by 3/4
∵ x = 9
∴ The corresponding x = 9 ÷ 3/4 = 9 × 4/3 = 36/3 = 12
∴ The corresponding point is (12 , -8)
