Answer:
A = 200.96 units^2
Step-by-step explanation:
We know the circumference is given by
C = 2 * pi *r
Approximating pi by 3.14
50.24 = 2 * 3.14 *r
50.24 = 6.28 r
Divide each side by 6.28
50.24/ 6.28 = 6.28r/6.28
8 =r
Now we can find the area
A = pi * r^2
A = 3.14 * r^2
A = 3.14 (8)^2
A = 200.96 units^2

The number of minutes Sadie spends on homework, playing outside, and practicing
piano are known. How much more time Sadie spends on homework, h, is unknown.
90 = (20 + 15) +h
Answer:
h = 55

90 = (20 + 15) +h
90 = 35 + h
90 - 35 = h
h = 55
The table below shows the total cost (TC) and marginal cost (MC) for Choco Lovers, a monopolistic firm producing different quantities
of chocolate gift boxes. Fill in the blanks in the table.
Answer:
Spreadsheet values
B3 = $15 (shown)C4 = $420 (shown)D6 = $272.5E4 = $6F2 = $16F6 = $5Other values
profit maximizing Q: 35profit maximizing P: $13maximum profit: $227.5Step-by-step explanation:
Labeling the columns of the spreadsheet A--F, and the rows 1--7, we want to find the values as follows.
a) The relationship between quantity, price, and revenue is ...
total revenue = quantity × price
price = (total revenue)/quantity
Then ...
B3 = 375/25 = 15 (as shown)C4 = 30×14 = 420 (as shown)__
b) The relationship between total cost and marginal cost is ...
mc2 = (tc2 -tc1)/(q2 -q1)
tc2 = (mc2)(q2 -q1) +tc1
Then ...
D6 = 9(40 -35) +227.5 = 272.5E4 = (192.5 -162.5)/(30 -25) = 6__
c) Marginal revenue is figured the same way as marginal cost.
mr2 = (r2 -r1)/(q2 -q1)
Then ...
F2 = (320 -0)/(20 -0) = 16F6 = (480 -455)/(40 -35) = 5__
d) The quantity maximizing profit will be the quantity such that marginal revenue is equal to marginal cost. That is, marginal profit is zero. That quantity is 35, where both marginal cost and marginal revenue are 7.
__
e) The price at a quantity of 35 is 13. This value is read from the given table.
__
f) The maximum profit is the difference between revenue and cost at the profit-maximizing quantity:
maximum profit = 455 -227.5 = 227.5
The question refers to Total Cost (TC) and Marginal Cost (MC) in economics; where TC is the sum of all production costs and MC is the cost of producing one more unit of a good. To fill the table, calculate the difference in total cost for each increase in produced units, as this difference reflects the MC.
Explanation:The question is referring to the concepts of Total Cost (TC) and Marginal Cost (MC) in economics. Total Cost is the complete expenditure made by a firm in the production process, including both fixed and variable costs. Marginal Cost, on the other hand, is the cost of producing one additional unit of a good. In the case of the Choco Lovers firm, it represents the cost of producing an extra box of chocolates.
To fill in the blanks in the table, the differences in total cost for each increase in the quantity of chocolate gift boxes produced should be calculated. This is because the MC at each level of output is the addition to total cost when one more box is produced. So, if total cost rises by $5 when output increases from 10 to 11 boxes, the MC of the 11th box is $5.

Consider the following graph, which details the observed bear population in two national parks. A graph titled Bears Observed in Park has month on the y-axis and number of bears observed on the y-axis, going from 37 to 53. In the same month, there are 2 points marked on the graph. All points are connected by overlapping lines. Of the following, which option or options would help make this graph less misleading? I. The scale on the x-axis should be resized. II. The scale on the y-axis should be resized. III. The identity of the two parks should be more clearly differentiated. a. I and II b. II and III c. III only d. I and III
ANSWER IS B
Answer:
b. II and III
Step-by-step explanation:
A graph is a data presentation that has two axis - x and y, divided into appropriate scales.
A scale is used to divide given units into equal parts. It is crucial to and used to create uniformity in drawing of graphs. Choosing a good scale to represent an information on a graph is vital to avoid confusion. This can be done by considering the variations in the values forming the data.
In the question, the single graph shows an information about the bear population in two national parks. Thus, the scale of the y-axis must be adjusted and the identity of the two parks be more differentiated so as to make the graph less misleading.

The list of options
Analyzing each statement, we have
a. On a coordinate plane, an absolute value function opens down.
The absolute value function f(x)=∣x∣ does not have an inverse that is a function because it fails the horizontal line test.
Specifically, any horizontal line intersects the graph of the absolute value function at most twice.
So, its inverse is not a function.
b. On a coordinate plane, an exponential function increases from quadrant 2 into quadrant 1.
Exponential functions, such as
f(x) = eˣ or f(x) = abˣ, do have inverses that are functions.
They pass the horizontal line test, and their inverses are logarithmic functions.
c. On a coordinate plane, a cubic function has an x-intercept of (0, 0).
A cubic function, such as f(x) = x³, does have an inverse that is a function.
The cubic function has an x-intercept at (0, 0), and its inverse is a cubic root function.

A trapezoid has an area of 30m^2. if all of its side lengths are tripled, what will its new area be
Answer:
270
Step-by-step explanation:
Because we do not know what the side lengths are, as long as they multiply to 30m^2, it's fine
For this question, let's just say the base is 5, and the height is 6. If we triple 5, we get 15, and if we triple 6, we get 18. 15*18=270
Now what if, the sides are not 5 and 6. Will the area still be the same? Let's find out.
10*3=30 so we can say for this answer, the base is 3, and the height is 10.
10 tripled is 30, and 3 tripled is 9. 30*9=270
So as we look at these 2 answers. we can conclude that the new area, no matter the side lengths, will be 270

Step-by-step explanation:
https://brainly.com/question/15495979
Benito drew a line with a slope of 3. This is determined by using the slope formula and identifying the rate of change in the y coordinates with respect to the x coordinates for each line drawn by the different students.
Explanation:To find the slope of a line on a coordinate plane, we can use the slope formula: slope = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are points on the line.
Analise's line goes through points (-3,0) and (0,1). The slope would be (1-0)/(0-(-3)) = 1/3.Benito's line goes through points (0, -1) and (1, 2). The slope is (2-(-1))/(1-0) = 3.Charlie's line is vertical, going through the points (0,-3) and (0,3). Vertical lines do not have a defined slope.Dariya's line passes through (2,3) and (3,0). The slope is (0-3)/(3-2) = -3.Therefore, the student who drew a line with a slope of 3 is Benito.

Square ABCD has a side length of 4 inches. The square is dilated by a scale factor of 4 to
form square A'B'C'D'. What is the side length of square A'B'C'D' ?
Answer:
The side of square A'B'C'D' is 16 inches
Step-by-step explanation:
Given
Length of Square ABCD = 4 inches
Dilated with a scale factor of 4
Required
Length of square A'B'C'D'
To dilate something means to enlarge or reduce the size of that thing, depending on the scale factor.
Consider the following conditions
When the scale factor is greater than 1, then the size of new shape will be bigger than the dilated shapeWhen the scale factor is equal to 1, the new shape will maintain the same size as the dilated shapeWhen the scale factor is less than 1 but greater than 0, the size of new shape will be smaller than that of the dilated shape.Having mentioned the conditions of dilation, Here, the "thing being dilated" is a square (ABCD) on a scale factor of 4.
The scale factor is greater than 1; so, the new shape (A'B'C'D) will be bigger than the previous shape (ABCD)
Now, how is the new size calculated?
The new size is calculated by multiplying the length of the previous shape by its scale factor;
In other words,
New Length = Old Length * Scale Factor
Where
Old Length = Length of ABCD = 4 inches
Scale Factor = 4
By Substitution,
New Length = 4 inches * 4
New Length = 16 inches
Hence, the side of square A'B'C'D' is 16 inches
