The Hanwell Company acquired a 30% equity interest in The Northfield Company for CU400,000 on 1 January 20X6. In the year to 31 December 20X6 Northfield earned profits of CU80,000 and paid no dividend. In the year to 31 December 20X7 Northfield incurred losses of CU32,000 and paid a dividend of CU10,000. In Hanwell's consolidated statement of financial position at 31 December 20X7, what should be the carrying amount of its interest in Northfield, according to IAS 28 Investments in associates?
Answers
Under the equity method, the investment is initially recognized at cost and adjusted thereafter for the investor's share of the post-acquisition profits or losses and dividends of the investee.
Here's how we can calculate the carrying amount of Hanwell's interest in Northfield at 31 December 20X7:
1. Initial investment: CU400,000
2. Share of Northfield's profits in 20X6 (30% x CU80,000): CU24,000
3. Share of Northfield's losses in 20X7 (30% x CU32,000): CU(9,600)
4. Dividend received from Northfield in 20X7 (30% x CU10,000): CU(3,000)
The carrying amount of Hanwell's interest in Northfield at 31 December 20X7 is therefore:
CU400,000 + CU24,000 - CU9,600 - CU3,000 = CU411,400
Therefore, according to IAS 28 Investments in Associates, the carrying amount of Hanwell's interest in Northfield in its consolidated statement of financial position at 31 December 20X7 should be CU411,400.

What is rectangle?In Euclidean geometry, a rectangle is a parallelogram with four small angles. Alternately, it might be regarded as a hexagon with a fundamental rule or one with equal angles. Another option for the parallelogram is a straight angle. Four vertices in a square have equal lengths. Four 90° angle vertices and equal parallel sides make up a quadrilateral with a rectangular cross section. Because of this, it is occasionally referred to as a "equirectangular rectangle". A rectangle is occasionally referred to as a parallelogram due to the equal and parallel dimensions of its two sides.
El = 3x + 5, EG = 5x + 16, and m IF G = 270 are all known values. We also understand that a rectangle's diagonals are of equal length. Hence, we can write:
El = HG
EG = IF
From the knowledge provided above, we can formulate two equations in terms of x:
3x + 5 = HG
5x + 16 = IF
90 m HG F and 90 m EFG
Since we know that GH is a straight line because m GHE = 0, m El G must be 180 degrees.
Now that the formulas for HG and IF are equivalent to one another, we may find x:
3x + 5 = 5x + 16
2x = 11\sx = 5.5
Hence, x = 5.5 and m El H = 180.

How much in one year?
give to charity each month?
Answers
Based on the given information, you would be giving $5 per month or $60 per year to charity.
How do we calculate the money we give to charity each month?Starting with a monthly gross income of $5,000, we can calculate the amount set aside for family activities as 10% of the gross income, which is:
= $5,000 x 0.10
= $500
Now, we will calculate the monthly allowance as 10% of the family activity money, which is:
= $500 x 0.10
= $50
Since you give 10% of your monthly allowance to support a charity organization, you will be giving:
= $50 x 0.10
= $5 per month
Now, in order to calculate how much you would give to charity in one year, we simply multiply the monthly amount by 12 which gives us:
= $5 x 12
= $60 per year
Therefore, the amount we would be giving to the charity is $5 per month or $60 per year.

Answers
Answer:
Step-by-step explanation:
To find the constant of proportionality, we can use the formula for a proportional relationship: y = kx, where y is the total cost, x is the number of songs, and k is the constant of proportionality.
Using the table, we can find two pairs of values for y and x:
When x = 6, y = $1.80
When x = 12, y = $3.60
We can set up a proportion:
y1 / x1 = y2 / x2
$1.80 / 6 = $3.60 / 12
Simplifying, we get:
$0.30 = $0.30
This tells us that the constant of proportionality is $0.30.
We can check this by using another pair of values:
When x = 20, y = $6
Using the formula y = kx, we get:
$6 = ($0.30)(20)
Simplifying, we get:
$6 = $6
This checks out, so we can be confident that the constant of proportionality is $0.30.

What is equation?An equation is a statement that asserts the equality of two expressions. Equations typically contain one or more variables, which are quantities that can take on different values. The goal of solving an equation is to find the values of the variables that make the equation true.Equations can take many different forms, but some common types include linear equations, quadratic equations, polynomial equations, and exponential equations.
What is expression?An expression is a combination of numbers, variables, and mathematical operations that represents a value. Expressions can contain constants, variables, and operators, such as addition, subtraction, multiplication, and division.
In the given question,
There are different ways to approach this problem, but one possible method is to use ratios. Let's assume that the cost of a dinner without any sides is x dollars. Then, the cost of a dinner with salad is x plus some additional amount for the salad, which we don't know yet. Let's call this additional amount y dollars. Therefore, the cost of a dinner with salad is x + y dollars.
According to the problem, Russell can buy 6 dinners with salads for $114. This means that the total cost of 6 dinners with salads is $114. We can write this as an equation: 6(x + y) = 114
Simplifying this equation, we get: 6x + 6y = 114
Dividing both sides by 6, we obtain: x + y = 19
Now we need to find the cost of 6 dinners without any sides, which is 6 times the cost of a dinner without any sides. We already know that the cost of one dinner without any sides is x dollars, so the cost of 6 dinners without any sides is 6x dollars.
To find x, we can use the fact that x + y = 19, which we derived from the given information. We don't know y, but we can express it in terms of x by using the fraction of the salad price to the total price of a dinner with salad. From the long division, we have:
2x - 3
x + 1
This means that y is equal to the remainder of the division, which is -3/(x+1). Therefore, we have: y = -3/(x+1)
Now we can substitute this expression for y into the equation x + y = 19:
x - 3/(x+1) = 19
Multiplying both sides by x+1, we get: x(x+1) - 3 = 19(x+1)
Expanding the products and simplifying, we obtain a quadratic equation:
x^2 + 18x - 22 = 0
We can solve this equation by using the quadratic formula:
x = (-18 ± √(18^2 + 4122)) / (2*1)
x = (-18 ± √(400)) / 2
x = (-18 ± 20) / 2
x = -9 or x = 2
Since we are interested in the cost of a dinner without any sides, which should be a positive number, we discard the negative solution and take x = 2. Therefore, the cost of one dinner without any sides is $2, and the cost of 6 dinners without any sides is 6 times that amount, which is $12. Answer: $12.

Find the c and y- intercepts of the parabola y = 3x^2 -9x + 9
Answers
The y-intercept is (0, 9), and the parabola has no x-intercepts.
What are intercepts?An intercept in mathematics is a location on the y-axis through which the line's slope passes. It is a place on the y-axis where a straight line or a curve crosses. This is reflected in the equation for a line, which is written as y = mx+c, where m denotes slope and c denotes the y-intercept.
X-intercept and Y-intercept are the two main intercepts. The line's x-intercept and y-intercept are located where the line crosses the x and y axes, respectively.
To find the y-intercept of the parabola, we set x = 0 and solve for y:
y = 3x² - 9x + 9
y = 3(0)² - 9(0) + 9
y = 9
Therefore, the y-intercept is (0, 9).
To find the x-intercepts, we set y = 0 and solve for x:
0 = 3x² - 9x + 9
0 = x² - 3x + 3
Using the quadratic formula, we get:
x = [3 ± √((-3)² - 4(1)(3))]/(2(1))
x = [3 ± √(9 - 12)]/2
x = [3 ± √(-3)]/2
The square root of a negative number is not a real number.
The parabola does not intersect the x-axis, and therefore, there are no x-intercepts.

What is quadratic equation?A quadratic equation is written in the form ax² + bx + c = 0, where a, b, and c are constants and a ≠ 0.
To solve this equation, we will use the quadratic formula.
The quadratic formula states that for a quadratic equation of the form ax² + bx + c = 0, the solutions are given by
x = [-b ± √(b² - 4ac)]/2a.
In this equation, a = x², b = -3x, and c = -1. Plugging these values into the formula, we get x = [3x ± √(9x² - 4(x²)(-1))]/2(x²). Simplifying this, we get
x = [3x ± √(9x² + 4)]/2x².
Now, we must solve for the two solutions. The first solution is x = (3x + √(9x² + 4))/2x². The second solution is
x = (3x - √(9x² + 4))/2x².
Therefore, the two solutions to the given equation are

Nakia is an architect designing a house with a peaked roof. She is trying to decide what the limitations are on her design. If AB is 8 feet and triangle ABC will be isosceles, describe the possible lengths for AC.
Answers
The possible lengths for AC are any values greater than the square root of 51.2 (approximately 7.15 feet).
How did we get the value?If triangle ABC is isosceles, then AC must be equal to BC. Let's call the length of AC "x".
Using the Pythagorean theorem, we can find the length of the diagonal line segment BD (which is also the height of the peaked roof):
BD^2 = AB^2 - (AC/2)^2
BD^2 = 8^2 - (x/2)^2
BD^2 = 64 - x^2/4
To ensure that the roof is peaked, we need BD to be less than x (otherwise, the roof would be flat). So we can set up an inequality:
BD < x
√(64 - x^2/4) < x
64 - x^2/4 < x^2
256 - x^2 < 4x^2
5x^2 > 256
x^2 > 51.2
x > √(51.2)
Therefore, the possible lengths for AC are any values greater than the square root of 51.2 (approximately 7.15 feet).

Define the rate of change and initial value of the function.The rate of change of a function refers to how much the output of the function changes with respect to changes in its input, typically expressed as the derivative of the function.
The initial value of a function refers to the value of the function at a specific point in its domain, often denoted as f(0) or f(x_0) for some value x_0 in the domain. It is called "initial" because it is usually the starting point for analyzing the behavior of the function over a range of inputs.
The given function is y=-150x+950,000, where x represents time in years and y represents the total population of pharaoh ants in Southeast Asia.
The initial value of the function is the y-intercept, which is 950,000. This means that at the beginning of the observation period (when x=0), there are 950,000 pharaoh ants in Southeast Asia.
The rate of change of the function is the coefficient of x, which is -150. This means that every year, the population decreases by 150,000 ants. Therefore, option A is correct because it states that the population decreases every year by 150,000 ants, which is the same as -150 multiplied by 1,000.

The proportion of the profit that each man gets is equal to the proportion of the capital that he invested. Therefore, the first man gets:
N2,000 / N7,500 * N300 = N80
The second man gets:
N4,000 / N7,500 * N300 = N160
The third man gets:
N1,500 / N7,500 * N300 = N60
Therefore, each man gets N80, N160, and N60, respectively.
Step-by-step explanation:
Answer:
N80, N160, and N60
Step-by-step explanation:
The total amount of capital invested is:
N2,000 + N4,000 + N1,500 = N7,500
The proportion of the profit that each man gets is equal to the proportion of the capital that he invested. Therefore, the first man gets:

What is number?Number is a mathematical object used to count, measure, and label. It is a fundamental concept in mathematics, and is used in nearly every branch of the discipline. In everyday life, the notion of number is used to count objects, keep track of scores, measure amounts, and label objects.
City TV Commercials Car Sales
A 60 20
B 50 15
C 70 25
D 45 17
E 55 19
Calculating the linear regression line:
m = Slope = (NΣXY - (ΣX)(ΣY)) / (NΣX2 - (ΣX)2)
= (5(1475) - (325)(95)) / (5(5850) - (325)2)
= (7375 - 30875) / (29250 - 105625)
= -38500 / -75375
= 0.51
b = Intercept = (ΣY - m(ΣX)) / N
= (95 - 0.51(325)) / 5
= (95 - 165.25) / 5
= -70.25 / 5
= -14.05
Therefore, the linear regression line is:
Y = 0.51X - 14.05.
