Final answer:
To find the volume of the box, convert all dimensions to centimeters and then use the formula length x width x height. The volume is 36 cm³.
Explanation:
To calculate the volume of a rectangular box with dimensions in different units, we must first convert all dimensions to the same unit of measure. In this case, we will convert meters and millimeters to centimeters:
0.09 m = 0.09 * 100 cm = 9 cm
20 mm = 20 / 10 cm = 2 cm
Now we can calculate the volume using the formula for the volume of a rectangular box, which is length × width × height:
Volume = 2 cm × 9 cm × 2 cm = 36 cm³

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

A displacement vector with a magnitude of 20. meters could have perpendicular components with magnitudes of
To find the perpendicular components of a displacement vector with a magnitude of 20 meters, use trigonometry and the Pythagorean theorem.
Explanation:The question asks for the perpendicular components of a displacement vector with a magnitude of 20 meters. Perpendicular components of a vector can be determined using trigonometry. Let's assume the vector has components Ax and Ay.
Using the Pythagorean theorem, Ax^2 + Ay^2 = 20^2. Since the components are perpendicular, we can set up a right triangle and solve for the components using the sine and cosine functions. For example, if one component is Ax = 10 meters, the other component Ay can be calculated using Ay = sqrt(20^2 - 10^2) = 10*sqrt(3) meters. Similarly, if one component is Ay = 10 meters, the other component Ax can be calculated using Ax = sqrt(20^2 - 10^2) = 10*sqrt(3) meters.

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.
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.

Joe bought a length of timber for his fence. He uses 1/5 of the wood for the first garden and 3/8 for the second garden. What fraction of the wood remains for the third garden
Joe used 1/5 of the timber for the first garden and 3/8 for the second garden. After converting these fractions to have a common denominator, we found that 23/40 of the timber was used. Therefore, 17/40 of the timber remains for the third garden.
The student is asking how much of the timber remains after Joe has used some for two gardens. Joe uses 1/5 of the wood for the first garden and 3/8 for the second garden. To solve this, we first add the fractions of wood used for both gardens to find out the total used fraction:
1/5 + 3/8
To add these fractions, we first need to find a common denominator, which in this case is 40. So we convert the fractions:
8/40 + 15/40} = 23/440
Now we subtract the used fraction from the total amount of timber, which is 1:
1 - 23/40 = 40 / 40 - 23 / 40= 17 / 40
Thus, 17/40 of the wood remains for the third garden.

The scale drawing of a flower bed has the dimensions of 3 inches by 7 inches. The dimensions of the actual flower bed are 36 inches by 84 inches.
What is the scale factor used to find the dimensions of the drawing?
The scale factor used to find the dimensions of the scale drawing is 1/12. This is found by dividing the dimensions of the drawing by the dimensions of the actual flower bed, confirming both scale factors for length and width are equal.
Explanation:The student is asking about determining the scale factor used to create a scale drawing from the actual dimensions of an object, which in this case is a flower bed. To find the scale factor, we compare the dimensions of the drawing with those of the actual object. For the given dimensions of the drawing, which are 3 inches by 7 inches, and the actual dimensions being 36 inches by 84 inches, we can find the scale factors for the length and width separately and confirm they are the same.
For the length, the scale factor is calculated as:
Scale factor for length = Length of drawing / Length of actual object
Scale factor for length = 3 inches / 36 inches = 1/12
For the width, the scale factor is calculated as:
Scale factor for width = Width of drawing / Width of actual object
Scale factor for width = 7 inches / 84 inches = 1/12
Thus, the scale factor for the scale drawing is 1/12. This means that each unit of measurement in the drawing represents 12 units in the actual flower bed.
