The equation representing the number of kilograms of oranges that the store needs to sell is: Remaining kilograms = -7 kg.
To determine the number of kilograms of oranges that the store still needs to sell, we can subtract the amount of oranges already sold from the target amount of oranges.
Let's denote the target amount of oranges as T and the amount of oranges already sold as S.
According to the information given, the store wants to sell 5 kilograms of oranges in one week, so T = 5 kg.
The store has already sold 12 kilograms of oranges, so S = 12 kg.
To find the remaining amount of oranges that the store needs to sell, we subtract S from T:
Remaining oranges = T - S
Substituting the values, we have:
Remaining oranges = 5 kg - 12 kg
Calculating the difference, we get:
Remaining oranges = -7 kg
The result is -7 kg, indicating that the store has sold more oranges (12 kg) than the target amount (5 kg). Therefore, the store needs to sell an additional 7 kilograms of oranges to reach its target.
In the equation form, we can write it as:
Remaining kilograms = Target kilograms - Sold kilograms
= 5 kg - 12 kg
= -7 kg

according to census the total number of male and female was 88,51,84,692, if number of male was 45,40,34,570what was the number of number of female population
Answers
According to census the total number of male and female was 88,51,84,692, if number of male was 45,40,34,570 the number of female population is 43,11,50,122.
To find the wide variety of girl population, we will subtract the quantity of male population from the full population.
Total population = 88,51,84,692
Number of male = 45,40,34,570
Number of female = Total population - Number of male
= 88,51,84,692 - 45,40,34,570

Answers
The sample that would have an estimate that is likely closest to the actual value of the population is C. 150.
Why would this sample be better ?The size of the sample has a direct impact on the likelihood of obtaining an estimate that closely approximates the actual parameter value of the population.
In this context, a larger sample size, such as the one in option C with a magnitude of 150, is more inclined to yield an estimate that is nearest to the true parameter value. The rationale behind this lies in the fact that a larger sample size mitigates the effects of sampling error, resulting in a more accurate and representative depiction of the entire population. Consequently, the estimate derived from a sample of 150 would be expected to offer a higher level of precision and proximity to the actual parameter value.

In this question, the binomial is (x + 2)².
You can expand this to be (x + 2)(x + 2).
When you expand it using the FOIL method, you get x times x, which is x².
Next, the outside/outer terms are x and 2, which is 2x.
Then, you multiply the inside/inner terms 2 and x, which is 2x.
Last, you multiply the last terms, which are 2 and 2, which is 4.
When you put them together, it looks like this:
x² + 2x + 2x + 4.
You can simplify this to x² + 4x + 4.

Find the component form of AB with initial point A(8, -2) and terminal point B(-2, -2).
Answers
The component form of AB with initial point A(8, -2) and terminal point B(-2, -2) is (-10, 0).
To find the component form of vector AB with initial point A(8, -2) and terminal point B(-2, -2), we need to subtract the coordinates of point A from the coordinates of point B.
Let's calculate the components:
The x-component of AB is obtained by subtracting the x-coordinate of point A from the x-coordinate of point B:
x-component = x-coordinate of B - x-coordinate of A
= -2 - 8
= -10
The y-component of AB is obtained by subtracting the y-coordinate of point A from the y-coordinate of point B:
y-component = y-coordinate of B - y-coordinate of A
= -2 - (-2)
= -2 + 2
= 0
In vector notation, we can represent vector AB as AB = (-10, 0), where the x-component represents the horizontal displacement and the y-component represents the vertical displacement from point A to point B.
Geometrically, the vector AB can be visualized as the directed line segment from point A to point B, with a horizontal displacement of -10 units and no vertical displacement (0 units). The negative sign indicates that the direction of AB is from right to left along the x-axis.

Brothers Jason and Neil go out for pizza. Jason chooses a rectangular piece of pizza measuring 10 cm by 15 cm. Neil’s piece will be cut from a circular pizza with diameter 30 cm. Neil wants his piece to be the same size as Jason’s. What angle should be made at the centre of the pizza?
Answers
The angle at the center of the circular pizza should be approximately 240.01° to make Neil's piece the same size as Jason's rectangular piece.
To determine the angle that should be made at the center of the circular pizza to obtain a piece the same size as Jason's rectangular piece, we need to compare the areas of the two shapes.
The area of Jason's rectangular piece is given by length times width, which is 10 cm × 15 cm = 150 cm².
The area of Neil's circular piece is given by the formula for the area of a circle, which is π times the square of the radius (A = πr²). Since the diameter is 30 cm, the radius is half of that, which is 15 cm. Thus, the area of Neil's piece is π × (15 cm)² =225π cm².
To make Neil's piece the same size as Jason's, we set up the equation:
150 cm² = 225π cm²
Now we solve for π:
π = 150 cm² / (225 cm²)
π ≈ 0.6667
To find the angle, we use the relationship between angles and the fraction of the circle's circumference they cover. Since π represents the fraction of the circumference, the angle is:
Angle = π × 360° ≈ 0.6667 × 360° ≈ 240.01°
Therefore, the angle at the center of the circular pizza should be approximately 240.01° to make Neil's piece the same size as Jason's rectangular piece.

D. (x, y) -+ (y, -x)
Answers
The transformation represents a reflection over the y = × line.
A. (x, y) → (-x, y)
A reflection over the y-axis is a transformation that flips a point or shape across the vertical line y = 0.
This means that points on the right side of the y-axis will be reflected to the left side, and vice versa.
Let's examine each option to determine which one represents a reflection over the y-axis.
A. (x, y) → (-x, y):
This transformation reflects the point across the y-axis.
For example, if we have a point (3, 2), after applying this transformation, it becomes (-3, 2).
This represents a reflection over the y-axis.
B. (x, y) → (-x, -y):
This transformation not only reflects the point across the y-axis but also flips it vertically.
For example, if we have a point (3, 2), after applying this transformation, it becomes (-3, -2).
This represents a reflection over the y-axis.
C. (x, y) → (y, x):
This transformation swaps the x and y coordinates of a point, which does not represent a reflection over the y-axis.
Instead, it represents a 90-degree rotation of the point.
D. (x, y) → (y, -x):
This transformation swaps the x and y coordinates of a point and negates the new x-coordinate.
It does not represent a reflection over the y-axis.
Instead, it represents a 90-degree rotation of the point in the counterclockwise direction.
Based on the explanations above, both options A and B represent a reflection over the y-axis.

The value of segment SP in the circle is 13.4.
Given is a circle with chords OP and QR, intersecting S, where QS = 19, QS = 15 and SR = 17 we need to find the value of SP,
To find the value of SP, we can use the property of intersecting chords in a circle, which states that when two chords intersect inside a circle, the product of the segments of one chord is equal to the product of the segments of the other chord.
In this case, we have two chords OP and QR intersecting at point S. Let's denote the lengths of the segments as follows:
QS = 19
QS = x (where S is the intersection of QR and OP)
SR = 17
SP = y (the segment we want to find)
According to the property mentioned above, we have:
QS × QS = QR × SR
15 × 17 = 19 × SP
SP = 15 × 17 / 19
SP = 13.4
Hence the value of segment SP in the circle is 13.4.

If the cost of my building is 85,000, my scrap value is 7,500 and the expected life is 31.5 years. What is the depreciation for one month. I'd like the answer and the formula.
205 was not the answer.
Answers
The depreciation for one month is approximately $205.03.
To calculate the depreciation for one month, we can use the straight-line depreciation method. The formula for straight-line depreciation is:
Depreciation per period = (Initial cost - Scrap value) / Expected life
Given that the cost of the building is $85,000, the scrap value is $7,500, and the expected life is 31.5 years, we can plug these values into the formula:
Depreciation per period = ($85,000 - $7,500) / 31.5
Simplifying the equation, we get:
Depreciation per period = $77,500 / 31.5
Dividing $77,500 by 31.5, the depreciation per period is approximately $2,460.32.
To find the depreciation for one month, we need to divide this amount by 12 (since there are 12 months in a year):
Depreciation per month = $2,460.32 / 12
Therefore, the formula for calculating the depreciation for one month using the straight-line method is: Depreciation per month = (Initial cost - Scrap value) / (Expected life in years * 12 months).

1.1.3. How many litres of milk does Lihle need to make 120 cupcakes? (2)
Answers
Lihle would need 30 liters of milk to make 120 cupcakes.
To determine the amount of milk Lihle needs to make 120 cupcakes, we can calculate the total milk requirement by multiplying the milk quantity per cupcake by the number of cupcakes.
Given that the recipe requires 250 milliliters (ml) of milk per cupcake, we can proceed with the calculation:
Convert milliliters to liters:
Since there are 1,000 milliliters in a liter, we divide 250 ml by 1,000 to get the milk quantity per cupcake in liters, which is 0.25 liters.
Multiply the milk quantity per cupcake by the total number of cupcakes: Multiply 0.25 liters (milk per cupcake) by 120 cupcakes.
0.25 liters/cupcake [tex]\times[/tex] 120 cupcakes = 30 liters.
Therefore, Lihle would need 30 liters of milk to make 120 cupcakes in a US curriculum class.
