Therefore , the solution of the given problem of inequality comes out to be the correct answer is (A) division property of inequality.
What does inequality actually mean?A mathematical inequality is a relationship or group of values without the equal sign. Equity usually comes after equilibrium. When two parameters are not equal, inequality results. Between equality and inequality, there are differences. Because the numbers are not equal or variable it was chosen to use the most common symbol (). Any difference, no matter how little or significant, can be utilised to compare values.
Here,
The correct answer is (A) division property of inequality.
Step 3 shows that
=> 2x > 10, and to solve for x,
we need to isolate x on one side of the inequality.
We can do this by dividing both sides by 2,
which gives x > 5. This is step 4.
The division property of inequality states that if a > b and c is a positive number, then a/c > b/c. In this case,
we have
=> 2x > 10, and
we can divide both sides by 2 (which is a positive number) to get
=> x > 5.
Therefore, the work between step 3 and step 4 is justified by the division property of inequality.

Alfonso Inc. acquired 100 percent of the voting shares of BelAire Company on January 1, 2020. In exchange, Alfonso paid $387,500 in cash and issued 100,000 shares of its own $1 par value common stock. On this date, Alfonso’s stock had a fair value of $15 per share. The combination is a statutory merger with BelAire subsequently dissolved as a legal corporation. BelAire’s assets and liabilities are assigned to a new reporting unit.
Answer:
This scenario describes a business combination in which Alfonso Inc. acquired 100% ownership of BelAire Company on January 1, 2020, using both cash and common stock as consideration. The combination is a statutory merger, meaning that BelAire is dissolved as a legal corporation and its assets and liabilities are assigned to a new reporting unit.
To record this business combination, Alfonso would need to perform a detailed analysis of the fair values of the assets and liabilities of BelAire as of the acquisition date, and allocate the total consideration paid (i.e., $387,500 in cash plus the fair value of 100,000 shares of Alfonso's common stock) to those assets and liabilities based on their fair values.
Assuming that the fair values of the assets and liabilities of BelAire on the acquisition date were as follows:
Assets:
Cash: $50,000
Accounts receivable: $100,000
Inventory: $150,000
Property, plant, and equipment: $400,000
Goodwill: $200,000
Liabilities:
Accounts payable: $75,000
Long-term debt: $250,000
The total fair value of BelAire's net assets is ($50,000 + $100,000 + $150,000 + $400,000 + $200,000) - ($75,000 + $250,000) = $575,000.
The allocation of the consideration paid would be as follows:
Cash paid: $387,500
Fair value of 100,000 shares of Alfonso's common stock: 100,000 shares x $15 per share = $1,500,000
Total consideration paid: $1,887,500
Allocation of consideration:
Cash: $50,000 / $575,000 x $1,887,500 = $164,348
Accounts receivable: $100,000 / $575,000 x $1,887,500 = $328,261
Inventory: $150,000 / $575,000 x $1,887,500 = $492,174
Property, plant, and equipment: $400,000 / $575,000 x $1,887,500 = $1,310,870
Goodwill: $200,000 / $575,000 x $1,887,500 = $657,391
Accounts payable: $75,000 / $575,000 x $1,887,500 = $246,739
Long-term debt: $250,000 / $575,000 x $1,887,500 = $818,478
The entry to record the acquisition would be:
Debit Property, plant, and equipment: $1,310,870
Debit Goodwill: $657,391
Debit Cash: $164,348
Debit Accounts receivable: $328,261
Debit Inventory: $492,174
Credit Accounts payable: $246,739
Credit Long-term debt: $818,478
Credit Cash: $387,500

This entry records the allocation of the total consideration paid to the assets and liabilities acquired, as well as the issuance of Alfonso's common stock to BelAire's shareholders.
If p - r = 11 and q - r = -5, what is the value of p - q? -16 -6 6 16
The value of the expression P-q will be 16. The correct option is C.
What is an expression?In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.
To find the value of p - q, we need to eliminate r from the two equations given to us.
We can do this by solving for r in one of the equations and then substituting that expression into the other equation.
Let's solve for r in the equation p - r = 11:
r = p - 11
Now we can substitute this expression for r into the equation q - r = -5:
q - (p - 11) = -5
Simplifying this equation by distributing the negative sign, we get:
q - p + 11 = -5
Subtracting 11 from both sides, we get:
q - p = -16
Therefore, p - q = -(q - p) = -(-16) = 16.
So the answer is 16.

the probability of selecting a card that is not prime from the set {4, 5, 6, 7, 8} is 0.6 or 60%.
How we solved?
To determine the probability of selecting a card that is not prime from the set {4, 5, 6, 7, 8}, we first need to identify which numbers in the set are prime.
The prime numbers in the set are 5 and 7, so the non-prime numbers are 4, 6, and 8.
The total number of cards in the set is 5.
Therefore, the probability of selecting a non-prime card is:
P(not prime) = number of non-prime cards / total number of cards
P(not prime) = 3 / 5
P(not prime) = 0.6 or 60%
So the probability of selecting a card that is not prime from the set {4, 5, 6, 7, 8} is 0.6 or 60%.

PLS HURRY. what is the mean absolute deviation of 2,3,3,6,1 will give brainliest
The mean absolute deviation of the set of numbers 2, 3, 3, 6, and 1 is 1.2.
What is the mean absolute deviation?
Mean absolute deviation (MAD) is a measure of the average absolute distance between each data value and the mean of a data set. Similar to standard deviation, MAD is a parameter or statistic that measures the spread, or variation, in your data.
To find the mean absolute deviation of a set of numbers, we first need to find the mean of the set. The mean is the sum of the numbers divided by the total number of numbers. For the set of numbers 2, 3, 3, 6, 1, the mean is:
mean = (2 + 3 + 3 + 6 + 1) / 5
= 15 / 5
= 3
Next, we need to find the absolute deviation of each number in the set from the mean. The absolute deviation is the absolute value of the difference between the number and the mean. For each number in the set, we calculate the absolute deviation as follows:
|2 - 3| = 1
|3 - 3| = 0
|3 - 3| = 0
|6 - 3| = 3
|1 - 3| = 2
To find the mean absolute deviation, we take the average of the absolute deviations. We add up the absolute deviations and divide by the total number of numbers in the set:
mean absolute deviation = (1 + 0 + 0 + 3 + 2) / 5
= 6 / 5
= 1.2
Therefore, the mean absolute deviation of the set of numbers 2, 3, 3, 6, and 1 is 1.2.

Angles A and C are supplementary. Find the measure of angle C.
Angle EAB is 74 degrees. Angle FCD is undetermined.
How do I solve this problem?
In the given situation where ∠A and ∠C are supplementary, the angle ∠C is 106°.
What are supplementary angles?Angles that add up to 180 degrees are referred to as supplementary angles.
For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°.
Two angles are complementary if their sum equals 90 degrees, and supplementary if their sum equals 180 degrees.
Because the three angles of a triangle sum up to 180° and the right angle has already taken up 90°, the two non-right angles in a right-angled triangle are complementary.
We say two angles "Complement" one other when their sums equal 90 degrees.
So, we already are aware of that:
∠A and ∠C are supplementary
∠A is 74°
Then, ∠C would be:
∠A + ∠C = 180
74 + ∠C = 180
∠C = 180 - 74
∠C = 106
Therefore, in the given situation where ∠A and ∠C are supplementary, the angle ∠C is 106°.

The area of the shaded region is 235.5 m².
What is the area of the shaded region?To find the area of the shaded region, we need to subtract the area of the inner circle from the area of the outer circle.
The outer radius of the ring can be found by adding the width of the ring to the inner radius:
Outer radius = inner radius + width
= 11 m + 3 m
= 14 m
The area of a circle is given by the formula:
Area = π × (radius)²
Therefore, the area of the inner circle is:
Area of inner circle = π × (11 m)²
= 121π m²
And the area of the outer circle is:
Area of outer circle = π × (14 m)²
= 196π m²
To find the area of the shaded region, we need to subtract the area of the inner circle from the area of the outer circle:
Area of shaded region = Area of outer circle - Area of inner circle

The first and second lengths are not possible lengths of triangle.
The third and fourth lengths are possible lengths of triangle.
What are the possible lengths of triangle?For the first case; 3 ft, 5 ft, 9 ft: Not possible. In a triangle, the sum of the lengths of any two sides must be greater than the length of the third side. However, in this case, 3 ft + 5 ft = 8 ft, which is less than 9 ft.
For the second case 11 cm, 6 cm, 17 cm: Not possible. Using the same reasoning as above, we see that 6 cm + 11 cm = 17 cm, which means that the three sides cannot form a triangle.
For the third case. 4 in., 4 in., 6 in.: Possible. The sum of any two sides is greater than the third side, since 4 in. + 4 in. = 8 in., which is greater than 6 in. Therefore, these lengths can form a triangle.
For the fourth case. 16 yd, 10 yd, 12 yd: Possible. Again, we see that the sum of any two sides is greater than the third side, since 10 yd + 12 yd = 22 yd, which is greater than 16 yd. Therefore, these lengths can form a triangle.

In 2012, the cost of a hamburger at a famous nationwide restaurant chain was $4.32. In 2022 the
price of the same hamburger is $6.12.
a. What is the average rate of change in the cost of the hamburger during this period?
b. Using the price in 2012 as an initial value, write a linear equation that models the cost of
the hamburger.
c. Using the model from part b, when will the price of the hamburger reach $7.02?
Answer:
Step-by-step explanation:
a. The average rate of change in the cost of the hamburger during the period from 2012 to 2022 can be calculated as the difference in the cost of the hamburger divided by the number of years between the two prices.
So, the average rate of change in the cost of the hamburger is:
(6.12 - 4.32) / (2022 - 2012) = 0.18
Therefore, the average rate of change in the cost of the hamburger during this period is $0.18 per year.
b. We can use the point-slope form of a linear equation to model the cost of the hamburger as it changes over time. Let y be the cost of the hamburger in dollars, and t be the number of years since 2012. We know that the cost of the hamburger in 2012 was $4.32, so we have a starting point of (0, 4.32).
Using the average rate of change calculated in part a, we can find the slope of the line:
slope = (6.12 - 4.32) / (2022 - 2012) = 0.18
Now we can write the equation of the line as:
y - 4.32 = 0.18t
y = 0.18t + 4.32
So, the linear equation that models the cost of the hamburger in terms of years since 2012 is y = 0.18t + 4.32.
c. To find when the cost of the hamburger will reach $7.02, we can substitute y = 7.02 into the equation we found in part b and solve for t:
7.02 = 0.18t + 4.32
2.7 = 0.18t
t = 15
So, the cost of the hamburger will reach $7.02 in the year 2012 + 15 = 2027.

The first curve, labeled x = y2 − 5, enters the window in the fourth quadrant, goes up and left becoming more steep, crosses the y-axis at approximately y = −2.2, changes direction at the point (−5, 0), goes up and right becoming less steep, crosses the y-axis at approximately y = 2.2, and exits the window in the first quadrant.
The second curve, labeled x = ey, enters the window almost vertically just right of the y-axis, goes up and right becoming less steep, crosses the first curve just right of the y-axis at approximately y = −2.3, crosses the x-axis at x = 1, and exits the window in the first quadrant.
The first horizontal line, labeled y = −1, begins at the point (−4, −1) on the first curve, goes right, and ends at the approximate point (0.4, −1) on the second curve.
The second horizontal line, labeled y = 1, begins at the point (−4, 1) on the first curve, goes right, and ends at the approximate point (2.7, 1) on the second curve.
The region is right of the first curve, left of the second curve, above the first horizontal line, and below the second horizontal line.

find the area of the surface generated by revolving the given curve about the x-axis. y equals 7 x comma space 0 less or equal than x less or equal than 1
The area of the surface generated by revolving the curve y = 7x about the x-axis over the interval [0, 1] is approximately 15.43 square units.
What is integration ?
Integration is a fundamental concept in calculus that involves finding the integral of a function, which is the area under the curve of the function between two given limits. It is the reverse process of differentiation and is used to find the antiderivative of a function. In other words, integration involves finding a function whose derivative is a given function. Integration is a powerful tool that is used in many fields, including physics, engineering, economics, and statistics, to name a few.
Given by the question:
To find the area of the surface generated by revolving the curve y = 7x about the x-axis over the interval [0, 1], we can use the formula:
[tex]A =2\pi \int\limits^a_b {y} \, ds[/tex]
where a and b are the limits of integration, ds is the arc length element, and y is the height of the curve at each point.
In this case, we can rewrite the curve as x = y/7 and use the formula for arc length:
[tex]ds = \sqrt[]{(1 + (dx/dy)^2) dy}[/tex]
We have dx/dy = 1/7, so [tex]ds =\sqrt{(1 + (1/49)) dy}[/tex].
Substituting this into the surface area formula, we get:
[tex]A = 2\pi \int\limits^1_0 {y \sqrt{(1 + (1/49)) } } \, dy[/tex]
Integrating, we get:
[tex]A = 2\pi (49/72) [y\sqrt{(1 + (1/49)) } + (1/3) *(1 + (1/98)^{3/2} ][/tex] from 0 to 1
[tex]A = 2\pi (49/72) [(1/7) \sqrt{(50/49)} + (1/3)*(99/98)^{3/2} ][/tex]
[tex]A = 2\pi (49/72) [(5/7)\sqrt{2} + (1/3)* (99/98)^{3/2} ][/tex]
A ≈ 15.43
Therefore, the area of the surface generated by revolving the curve y = 7x about the x-axis over the interval [0, 1] is approximately 15.43 square units.

The value went from $45.00 to $68.75. What was the percent change?
The percent change from $45.00 to $68.75 is approximately 52.8%.
What does the phrase "percent change" mean?Finding the difference between two values in a time series and multiplying it by 100 after dividing it by the initial value yields the percentage change between the two values.
We employ the following formula to determine the percentage difference between two values:
(New Value - Old Value) / Old Value * 100% is the formula for percent change.
The former value in this instance was $45.00, whereas the new value is $68.75.
Adding these values to the formula yields the following results:
($68.75 - $45.00) / $45.00 * 100% is the percent difference.
percent modification: (23.75% / (45.00%) * 100%
52.8% change in percentage
As a result, the percentage increase from $45.00 to $68.75 is almost 52.8%.

Math Word Problem: A farmer had some chickens and some cows. She counted 40 heads and 126 legs. How many chickens and how many cows did she have? Show your work.
Answer:
There are 17 chickens and 23 cows
Step-by-step explanation:
Assuming every chicken has 1 head and 2 legs and every cow has 1 head and 4 legs, let us set up a system of equations for this proble
Let
x = number of chickens
y = number of cows
x chickens will have x heads
y cows will have y heads
Total number of heads = x + y = 40
x chickens will have 2x legs
y cows will have 4y legs
Total legs = 2x + 4y = 126
We have two equations:
x + y = 40 (1)
2x + 4y = 126 (2)
Multiply: (1) x 2
=> 2(x + y) = 2(40)
=> 2x + 2y = 80 (3)
Subtract: (2) - (3)
2x + 4y - (2x + 2y) = 126 - 80
2x + 4y -2x - 2y = 46
4y - 2y = 46
2y = 46
y = 23
Since y = 23 and x + y = 40
x + 23 = 40
x = 40 - 23 = 17
There are 17 chickens and 23 cows
