Option (A) is the correct answer: Panel a illustrate Increasing Return to Scale and panel b illustrate Constant Return to Scale.
Return to Scale:
It is the Variation or change in productivity that is the outcome from a proportionate increase of all the input.
Increasing Return to Scale:
An increasing return to scale occurs when the output increase by a larger proportion than the increase in inputs during the production process. For Example: if input is increased by 3 times but output increases by 3.75 times, then the firm or economy has experienced an increasing return to scale. This increase is due to many reasons like division external economies of scale.
Constant Return of Scale:
Constant Return of Scale refers to the production situation in which output increases exactly in the same proportion in which factors of production are increased. In simple words, if factors of production are doubled output will also be doubled. In this case, internal and external economies are exactly equal to internal and external diseconomies. This situation arises when after reaching a certain level of production, economies of scale are balanced by diseconomies of scale. For Example: A car wash in which one car wash takes 30 minutes. If there is one wash space and two workers running two 8 hours shifts total product would be 32.

The inequality is x ≤ 39.2. The actual number of items that can be bought is 39.
There is a set budget of $145 to buy some items. The price of each item is $3.70. We need to form an inequality for the given information and solve it.
Let the number of items be denoted by the variable "x". Then we can say that :
3.70*x ≤ 145
x ≤ 145/3.70
x ≤ 39.2
The actual number of items that can be bought must be a whole number. We will take the greatest integer less than or equal to the solution.

She bought 13 books in $58.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
Let b represent the number of books.
So, the equation will be
5b - 7 = 58
Now, add 7 to both sides of the equation
5b = 65.
b = 13.
Thus, she bought 13 books at 5 dollars a piece.
After she gets a 7 dollar discount off of 65 dollars, so she paid a total of 58 dollars after the discount.

Order the sides of DEF in order from least to greatest
The sides of DEF in order from least to greatest will be x + 6, (5x - 8) and (9x + 2).
How to calculate the angle?The total angles that can be found in a triangle is 180°.
Therefore, the angles will be illustrated thus:
x + 6 + (5x - 8) + (9x + 2) = 180°
x + 6 + 5x - 8 + 9x + 2 = 180°
15x = 180°
Divide
x = 180° / 15.
x = 12°
Therefore,
x + 6 = 12 + 6 = 18°
(5x - 8) = 5(12) + 8
= 60 + 8
= 68°
(9x + 2) = 9(12) + 2
= 108 + 2
= 110°

True or false :If an integer is negative, its absolute value is also its additive inverse.
The statement 'If an integer is negative, its absolute value is also its additive inverse.' is True.
In this question, we have been given a statement 'If an integer is negative, its absolute value is also its additive inverse.'
We know that for any non zero real number 'm', the additive inverse is '-m'
as m + (-m) = 0
We know that the absolute value of any non-zero real number is always positive.
Consider a negative integer -p.
The absolute value of -p is |-p| = p
We can observe that -p + p = 0
-p + |-p| = 0

The y-intercept is y = 10, and that is the initial height of the flower in inches.
And the rate of change between n = 1 and n = 5 is:
R = 0.21
What is the y-intercept?For any function y = f(x), the y-intercept is the value that y takes when we evaluate in x = 0.
In this case, we have the exponential function:
g(n) = 10*(1.02)^n
Evaluating in n = 0 we get:
g(0) = 10*(1.02)^0 = 10*1 = 10
The y-intercept is y = 10, and it means that the initial height of the flower is 10 inches.
Now we want to get the average rate of change on the interval [1, 5].
Remember that for a function f(x) the average rate of change on an interval [a, b] is:
R= [ f(b) - f(a)]/(b - a)
In this case we will have:
R = [ g(5) - g(1)]/(5 - 1) = [g(5) - g(1)]/4
Where:
g(5) = 10*(1.02)^5 =11.041
g(1) = 10*(1.02) = 10.200
Replacing that:
R = [11.041 - 10.200]/4 = 0.21
This means that the plant increases about 0.21 inches per day on these 4 days.

Of all the closed right circular cylindrical cans of volume 128πcm
3, find the dimensions of the can which has minimum surface area.
The can's minimum surface area should have a height of 8 cm and a radius of 4 cm.
Given:
The volume of closed right circular cylindrical cans = 128π cm³
As we know the volume of a cylinder = πr²h
By equating;
πr²h = 128π
h = 128/r²
To get the dimensions of a can with minimum surface area;
S = 2πrh + 2πr
Put h = 128/r²;
Therefore, S(r) = 256π/r + 2πr²
S'(r) = -256π/r² + 4πr
S''(r) = -(2*256π)/r³ + 4π
Now, for S(r) = 0;
r = 4cm
for S''(4) > 0 at r = 4 is minimum point.
Hence,
h = 128π/(π*4*4)
h = 8cm
Therefore, the minimum surface area of the can should have a radius of 4 cm and a height of 8 cm.

10-6x + 9x = x+2 solving variables
The required value of the variable x is - 4
What are variables ?A variable in mathematics is an alphabet or phrase that stands in for an unknowable amount, unknowable value, or unknowable number. Particularly in the case of algebraic expressions or algebra, the variables are utilised. As an illustration, the linear equation x+9=4 has the variables x and 9 as constants.
The given equation is :
10-6x + 9x = x+2
On solving this equation we get :
10 + 3x = x + 2
Subtract - 3x on both sides and we will get
10 = - 2 x + 2
Subtract 2 on both sides
we get
8 = -2x
On dividing both sides of the equation by 2 we get
x = - 4
Thus the required value of the variable x is - 4

HELPPP so the man bought a tv worth $1,700, and then each week he continued to spend $700 weekly WHAT IS THE EXPRESSION???? HELP (variable is X)
HELP
Answer: 700x+1700
This represents the total amount spent over the x weeks that have gone by.
===========================================
Explanation:
x = number of weeks
700x = amount spent over those x weeks ($700 per week)
700x+1700 = total amount spent when adding on the $1700 tv.
------
An example:
Let's say x = 10 weeks have elapsed. He spends $700 a week, so 700x = 700*10 = 7000 dollars have been spent so far if we ignore the tv. Then add on the $1700 tv cost to get 7000+1700 = 8700 dollars total spent.
Then note how 700x+1700 = 700*10+1700 = 8700 matches what we got earlier.
I recommend trying out other values of x to get a better idea of what's going on.

The line of best fit for the data presented in the scatterplot is y = 0.5x. (Option B)
A line of best fit represents a straight line that is the best approximation of the given set of data used to examine the nature of the relation between two variables. It is an educated guess about where a linear equation might fall in a set of data plotted on a scatter plot. The slope-intercept form of a linear equation is given by y = mx + b where m is the slope of the line and b is the y intercept of the graph. For any two points (x1, y1) and (x2, y2), the slope is given by:
m = (y2-y1)/(x2-x1)
Choosing two points from the line say (180, 90) and (220,110),
m = (110 – 90)/(220 – 180) = 20/40 = 0.5
Hence, y = 0.5x + b
Substituting a point from the graph into the equation say (240, 120)
120 = 0.5(240) + b
120 = 120 + b
b = 0
Hence, the equation is y = 0.5x

If they give a gratuity of 20 percent, rounded to the nearest dollar, what is the total cost of the dinner, including the tip?
The amounts, using proportions, are given as follows:
Tip: $10.93.Total cost of the meal: $65.58.What is a proportion?A proportion represents a fraction relative to a total amount, and this fraction is combined with the basic arithmetic operations, especially multiplication and division, to find the desired amounts in the context of the problem from which the fraction was built.
The tip is of 20% of the total bill of $54.65, hence it's value is given as follows:
Tip = 0.2 x 54.65 = $10.93.
(because 0.2 is the decimal equivalent to the percentage of 20%, then it is multiplied by the total amount to find the desired amount).
The total cost of the meal is given by the sum of the bill of the meal plus the tip, hence:
Total Cost = 54.65 + 10.93 = $65.58.

Thus;
Distance is calculated from the formula;
Distance = Speed * time
Thus;
Distance covered by Mary in the 2 hours lead is;
Distance = 45 * 2 = 90 miles
