A sports club is holding a fundraiser dinner. The function graphed models the profit, y, in dollars, from selling x tickets.
Select True or False to describe each statement.
Let
x-------> the number of tickets
y------> the profit in dollars
Let
[tex]A(0,-400)\ B(40,0)[/tex]
Find the slope of the linear equation
The slope is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
substitute
[tex]m=\frac{0+400}{40-0}[/tex]
[tex]m=10\frac{\$}{ticket}[/tex]
the linear equation is
[tex]y=10x-400[/tex]
Statements
case A) The y-intercept represents the cost per ticket
The statement is false
The cost per ticket represent the slope of the linear equation
The y-intercept is the value of the profit for a number of tickets equal to zero
In this problem the y-intercept is the point [tex](-400,0)[/tex]
case B) The slope represents the money spent before the sale of the first ticket
The statement is False
The slope represents the cost per ticket
the money spent before the sale of the first ticket is the y-intercept
case C) The sports club must sell more than [tex]40[/tex] tickets to make a profit
The statement is True
Because
we know that
For [tex]x=40\ tickets[/tex]
the value of the function is
[tex]y=0[/tex]
in the linear equation
[tex]y=10x-400[/tex]
For [tex]x>40\ tickets[/tex]
the profit will be
[tex]y > 0[/tex] --------> see the graph
therefore
the answer is
The sports club must sell more than [tex]40[/tex] tickets to make a profit

Find the angular velocity of a wheel that makes 30 revolutions in 10 seconds.
1.5π rad/sec
3π rad/sec
6π rad/sec
The angular velocity of the wheel is 6π rad/sec.
What is angular velocity?Angular velocity is the speed at which the angle between two bodies changes as an item rotates or revolves around an axis.
In one revolution,
The angular velocity is 2π rad/sec.
In 30 revolutions,
The angular velocity is 2π x 30 rad/ 10sec.
The angular velocity is 60π rad/sec.
The SI unit of angular velocity is radians per second.
Hence, The wheel's angular velocity is 6 rad/sec.

A warehouse is packing materials to ship out to a customer. A small box has the dimensions of x inches, (x+ 2) inches and (2x) inches. Where x is the length in inches of width. A large box has the dimensions of (x+5) inches, (x + 7) inches and (3x) inches.
*Recall that Volume = (Length)(Width)(Height)
Part 1: Write an expression that represents the dimensions of the small box.
Part 2: Write an expression that represents the dimensions of the large box.
Part 3: What is the difference in the volumes of the two boxes? Show or explain or work.
1. The expression that represents the dimensions of the small box is (2x³ + 4x²).
2. The expression that represents the dimensions of the large box is (3x³ + 36x² + 105x).
3. The difference in the volumes of the two boxes is (x³ + 32x² + 105x)
What is the volume of the box?1.
Small box:
x inches,
(x+ 2) inches and
(2x) inches
Volume = length × width × height
= x × (x + 2) × (2x)
= (x² + 2x) × 2x
= 2x³ + 4x²
2.
Large box:
(x+5) inches,
(x + 7) inches and
(3x) inches.
Volume = length × width × height
= (x + 5) × (x + 7) × (3x)
= 3x³ + 36x² + 105x
4.
Difference in volume = Large box - Small box
= (3x³ + 36x² + 105x) - (2x³ + 4x²)
= 3x³ + 36x² + 105x - 2x³ - 4x²
= x³ + 32x² + 105x
Therefore, x³ + 32x² + 105x is the expression which represents the volume of the box.

Billie and Toni are driving from Chicago to Phoenix. The first day they drove 420 miles. They want to drive at 65 miles per hour for the rest of their trip. a. Write an algebraic expression to represent the situation. b. If they drive 8 hours a day for the next two days, how far have they traveled by the end of the third day?
A. We are given that they already drove 420 miles and an additional of 65 miles per hour. Therefore distance covered is:
d = 420 + 65 t
where d is distance and t is time
B. If they drove 8 hours per day for 2 days, then total time is t = 16 hours, hence:
d = 420 + 65 * 16
d = 1460 miles

The town Atlanta needs $14,000 for a new playground Lanzetta Elementary school raise $5358 Lantana middle school race $2834 Atlanta high school raised eig The town Atlanta needs $14,000 for a new playground Lanzetta Elementary school raise $5358 Lantana middle school race $2834 Atlanta high school raised $4132 about how much more do they need to raise choose the best estimate
To find out how much more money is needed for the Atlanta playground, add the amounts raised by each school and subtract from the total amount needed. The schools have raised $12,324, so they still need about $1676. Therefore, $1676 more is required to meet the goal.
Let's calculate how much money the schools have already raised:
Lanzetta Elementary School raised $5358Lantana Middle School raised $2834Atlanta High School raised $4132First, add these amounts together:
$5358 + $2834 + $4132 = $12,324Next, subtract the total amount raised from the total money needed:
$14,000 - $12,324 = $1676Therefore, the town of Atlanta still needs to raise about $1676 for the new playground.

When matter changes state, what two things are always conserved?
In a change of state, mass and energy are the two things that are always conserved, in accordance with the law of conservation of matter and the first law of thermodynamics, respectively.
When matter changes state, the two things that are always conserved are mass and energy. This is explained by the law of conservation of matter, which states that the total mass of the products must equal the total mass of the reactants in a chemical reaction, and the law of conservation of energy, often referred to as the first law of thermodynamics.
In any given closed system, neither mass nor energy is created or destroyed, but can be transformed from one form to another. For example, when a substance burns, its matter is not lost but is instead transformed into other substances with the same total mass. Likewise, energy can be moved or transformed, but the total amount of energy remains constant. These principles apply to both living and non-living systems, keeping the total quantity of matter and energy fixed in the universe.

stella writes 1/7 of a page in 1/5 of a minute. how many minutes doesn’t it take her to write a full page?
It takes Stella 1.4 minutes to write a full page, calculated by setting up a proportion based on her rate of writing [tex]\frac{1}{7}[/tex] of a page in 1/5 of a minute.
Stella writes [tex]\frac{1}{7}[/tex] of a page in [tex]\frac{1}{5}[/tex] of a minute. To calculate how many minutes it takes her to write a full page, we can set up a proportion. Since 7/7 would make a full page, we'd need Stella to write seven times as much as she does in 1/5 of a minute. So, the math to find the time for a full page looks like this:
[tex]\frac{1}{7}[/tex] page : [tex]\frac{1}{5}[/tex] minute = 7/7 page : x minutes
Now multiply both sides by (1/5) minutes to isolate x:
[tex]\frac{1}{7}[/tex] / [tex]\frac{1}{5}[/tex] = 1/x
Cross multiply to solve for x:
[tex]\frac{1}{7}[/tex] * x = [tex]\frac{1}{5}[/tex]
x = [tex]\frac{1}{5}[/tex] / [tex]\frac{1}{7}[/tex]
x = [tex]\frac{1}{5}[/tex] * (7/1)
x = 7/5 minutes
x = 1.4 minutes
Therefore, it takes Stella 1.4 minutes to write a full page.
