To make a profit of at least $600, the number of bookends that need to be sold is calculated by adding the desired profit to the initial cost, and then dividing this sum by the net revenue per bookend. The result is approximately 144 bookends.
Explanation:The subject of this problem is Mathematics, specifically a topic within business math called 'breakeven analysis' or 'cost-volume-profit analysis'. It involves calculating the point at which revenue from selling a product equals the costs associated with producing and selling that product. In this case, you have spent $154 to make wooden bookends, and you plan on selling them online for $8.50 each. Additionally, there's a $3.25 fee per bookend for wrapping and shipping, which you charge to your customers. Your goal is to make a profit of at least $600.
To calculate the number of bookends that need to be sold, we first find the net revenue per bookend. This is the selling price minus the shipping cost, which comes out to $8.50 - $3.25 = $5.25 per bookend. The desired profit is added to the cost of making the bookends to find the total required revenue, which is $600 + $154 = $754.
Finally, total required revenue is divided by the net revenue per bookend to find the number of bookends that need to be sold: $754 ÷ $5.25 = approximately 144 bookends (rounded up to the nearest whole bookend since we can't sell a fraction of a bookend). So, in order for your profit to be at least $600, you must sell at least 144 bookends.

How many degrees are in each interior angle of a regular pentagon? 50 72 108 120
The answer 108 degrees.
Answer: [tex]108^{\circ}[/tex]
Step-by-step explanation:
The sum of all the angles in a regular polygon with sides n , is given by :-
[tex]S_n=180^{\circ}(n-2)[/tex]
Now, the sum of all the angles in a regular pentagon with 5 sides will be :-
[tex]S_5=180^{\circ}(5-2)=180^{\circ}(3)=540^{\circ}[/tex]
We know that all the interior angles of a regular polygon are equal .
Therefore, the measure of each interior angle in a pentagon is given by :-
[tex]x=\dfrac{540^{\circ}}{5}=108^{\circ}[/tex]
Hence, the measure of each interior angle in a pentagon=[tex]108^{\circ}[/tex]

A variable is: an instruction for the compiler a location in memory where a value can be stored a description of a value (such as a number or character) none of the above.
Final answer:
A variable is a name assigned to a quantity that can take on various values, and is used by mathematicians, economists, and statisticians in different contexts to represent data or elements of an equation.
Explanation:
A variable is the name given to a quantity that may assume a range of values. Mathematicians and economists often use variables in equations to represent different aspects of a problem or scenario. For example, in the equation of a line, commonly expressed as y = mx + b, the variables are 'x' and 'y'. Here, 'x' typically represents values on the horizontal axis, and 'y' represents values on the vertical axis, while 'b' is the y-intercept, and 'm' is the slope of the line. To understand how an equation with variables functions, we can look at a numerical example.
In statistics, variables can also refer to characteristics or measurements that can be determined for each member of a population. These variables can be numerical or categorical. A numerical variable, such as 'X' representing the number of points earned by a math student, allows for mathematical calculations like averaging. A categorical variable, like 'Y' indicating a person's political party affiliation, places individuals into categories and doesn't lend itself to mathematical operations like averaging.

A Springer Spaniel weighs 20 kilograms 490grams. A Cocker Spaniel weighs 7,590 grams less than a Springer Spaniel. A Newfoundland weighs 52 kilograms 656 grams more than a Cocker Spaniel. What is the difference, in grams, between the weights of the Newfoundland and the Springer Spaniel?
To find the difference in weight between the Newfoundland and the Springer Spaniel, subtract the weight of the Springer Spaniel from the weight of the Newfoundland.
Explanation:To find the difference in weight between the Newfoundland and the Springer Spaniel, we need to subtract the weight of the Springer Spaniel from the weight of the Newfoundland. The Newfoundland weighs 52 kilograms 656 grams more than a Cocker Spaniel. So, we first need to find the weight of a Cocker Spaniel by subtracting 7,590 grams from the weight of the Springer Spaniel. We then add this weight to the weight of the Newfoundland to get the final answer. Let's calculate:
The weight of the Cocker Spaniel = Weight of Springer Spaniel - 7,590gThe weight of the Newfoundland = Weight of Cocker Spaniel + 52kg 656gFinally, the difference in weight between the Newfoundland and the Springer Spaniel is the weight of the Newfoundland - weight of the Springer SpanielWe can now substitute the given values into these equations and solve.

Describe how the variability of the x bar distribution changes as the sample size increases
The standard deviation decreases and the sampling distribution becomes more normal as the sample size increases in x bar distribution.
The variability of the x bar distribution changes as the sample size increases. As the sample size increases, the standard deviation of the sampling distribution of the means will decrease, approaching the standard deviation of X. The sampling distribution of the mean becomes more normal as the sample size grows, showing less variability.

Adam earns a base pay plus a commission for each car he sells at Crazy Carl's Cool Cars. His monthly salary is modeled by the function f(c) = 250c + 500. If Adam doesn't sell a car, how much money does he earn for the month?
Answer: 500
Step-by-step explanation:
Since, The monthly salary is modeled by the function,
f(c) = 250 c + 500.
According to the question,
Adam earns a base pay plus a commission for each car he sells at Crazy Carl's Cool Cars.
In the given function c is a variable.
Thus, c must show the number of cars.
Thus, the base pay must be free from any variable.
In the above expression 500 is free from the variable c therefore, 500 is the base pay of Adam.
⇒ f(c) is the total earning by Adam after selling a car.
If he Does not sell any car then c=0,
f(0) = 250×0+500 = 500
Therefore, if he does not sell any car then his earning is 500.

If sinθ = -1/2 and θ is in Quadrant III, then tanθ = _____.
Answer: [tex]\tan \theta=\dfrac{1}{\sqrt3}.[/tex]
Step-by-step explanation: Given that
[tex]\sin\theta=-\dfrac{1}{2}[/tex] and [tex]\theta[/tex] lies in Quadrant III.
We are to find the value of [tex]\tan \theta.[/tex]
We will be using the following trigonometric identities:
[tex](i)~sin^2\theta+\cos^2\theta=1,\\\\(ii)~\dfrac{\sin\theta}{\cos{\theta}}=\tan \theta.[/tex]
We have
[tex]\tan\theta\\\\\\=\dfrac{\sin\theta}{\cos\theta}\\\\\\=\dfrac{\sin\theta}{\pm\sqrt{1-\sin^2\theta}}\\\\\\=\pm\dfrac{-\frac{1}{2}}{\sqrt{1-\left(\frac{1}{2}\right)^2}}\\\\\\=\pm\dfrac{\frac{1}{2}}{\sqrt{1-\frac{1}{4}}}\\\\\\=\pm\dfrac{\frac{1}{2}}{\frac{\sqrt3}{2}}\\\\\\=\pm\dfrac{1}{\sqrt3}.[/tex]
Since [tex]\theta[/tex] lies in Quadrant III, so tangent will be positive.
Thus,
[tex]\tan \theta=\dfrac{1}{\sqrt3}.[/tex]

Which property justifies this statement? If 4x=20, then x=5. Division Property of Equality Reflexive Property of Equality Substitution Property of Equality Subtraction Property of Equality
Answer:
Option 1 - Division Property of Equality
Step-by-step explanation:
Given : If [tex]4x=20[/tex], then x=5.
To find : Which property justifies this statement?
Solution :
The equation is [tex]4x=20[/tex]
To make variable separate we have to remove 4 which is in multiple of variable x.
So, We divide both side by 4,
Applying division property of equality,
We can divide both sides of an equation by the same number and preserve equality.
[tex]\frac{4x}{4}=\frac{20}{4}[/tex]
[tex]x=5[/tex]
Therefore, The property justifies the statement is 'Division Property of Equality'.
So, Option 1 is correct.
