Answer:

The meat production per animal obtained from a non-superior breed pig = 4.8 kg of meat per non superior breed of pig.

Producția de carne pe animal obținută de la un porc de rasă non-superioară = 4,8 kg de carne pe o rasă de porc non-superioară.

Step-by-step explanation:

English Translation

A quarter of the number of pigs on the farm, being of superior breed, bring at the end of the year, on average, a production of 9.6 kg of meat per animal. The production thus obtained represents half of total meat production, Determine the meat production per animal obtained from a non-superior breed pig.

Solution

Let the meat production per animal for the non superior breed of pig be y

Let the total number of pigs be x

A quarter of the pigs are superior breed, 0.25x, bring in 9.6 kg of meat per superior breed of pigs.

Total amount of meat produced by the superior breed of pigs = 0.25x × 9.6 = (3.6x) kg

This means that there are three quarter pigs from the less superior breed, 0.75x, making y kg of meat per animal.

Total amount of meat produced by the non superior breed of pigs = 0.75x × y = 0.75xy kg

Total meat production = (3.6x + 0.75xy) kg

It is then given that the total amount of meat from the superior breed is half of the total meat production.

That is,

3.6x = (3.6x + 0.75xy)/2

7.2x = 3.6x + 0.75xy

7.2x - 3.6x = 0.75xy

3.6x = 0.75xy

y = (3.6/0.75) = 4.8 kg

Hence, the meat production per animal obtained from a non-superior breed pig = 4.8 kg of meat per non superior breed of pig.

In Romanian/In limba romana

Permiteți producția de carne pe animal pentru rasa non superioară de porc

Fie numărul total de porci x

Un sfert din rasa superioară, 0,25x, aduce 9,6 kg de carne pentru fiecare rasă superioară de porci.

Un sfert din porci sunt de rasa superioară, 0,25x, aduc 9,6 kg de carne pe rasă superioară de porci.

Cantitatea totală de carne produsă de rasa superioară de porci = 0,25x × 9,6 = (3,6x) kg

Aceasta înseamnă că există trei sferturi de porci de la rasa mai puțin superioară, 0,75x, ceea ce face y kg de carne pe animal.

Cantitatea totală de carne produsă de rasa non superioară de porci = 0,75x × y = (0,75xy) kg

Producția totală de carne = (3,6x + 0,75xy) kg

Se consideră că cantitatea totală de carne de la rasa superioară este jumătate din producția totală de carne.

Acesta este,

3,6x = (3,6x + 0,75xy) / 2

7,2x = 3,6x + 0,75xy

7,2x - 3,6x = 0,75xy

3,6x = 0,75xy

y = (3,6 / 0,75) = 4,8 kg

Prin urmare, producția de carne pe animal obținută de la un porc de rasă non-superioară = 4,8 kg de carne la o rasă de porc ne superioară.

Step-by-step explanation:

The entrepreneur's revenue is  $2325x, entrepreneur's cost is $33,750 + $1700x and entrepreneur's profit from x sold-out performances is  $625x - $33,750

The entrepreneur's revenue from x sold-out performances is given by the formula:

Revenue = (Price per Performance) x (Number of Performances)

Revenue = $2325 x x

Revenue = $2325x

The entrepreneur's cost from x sold-out performances is given by the formula:

Cost = Overhead + (Production Cost per Performance) x (Number of Performances)

Cost = $33,750 + $1700x

The entrepreneur's profit from x sold-out performances is the revenue minus the cost:

Profit = Revenue - Cost

Profit = $2325x - ($33,750 + $1700x)

Profit = $625x - $33,750

10/50 = 20/100

Step-by-step explanation:

Another way to represent this formula is:

\(\frac{is}{of} = \frac{percent}{100}\)

Allow me to explain this to you.

What is 20% of 50?

"WHAT IS"

"20% (PERCENT)"

"OF 50"

\(\frac{x}{50} =\frac{20}{100}\)

The variable, x, was used to replace the unknown value, which is 10.

Anna's total profit was $6000 + $16000 - $4000 = $14000.

How did Anna earn profit

Anna bought $4000 of company stock. The value of the stock doubled when she sold 75% of it, which means she sold 0.75 * $4000 = $3000 worth of stock when its value doubled.

Since the value of the stock doubled, Anna sold the $3000 worth of stock for 2 * $3000 = $6000.

Anna then sold the remainder of the stock (25% of the original amount) for four times the purchase price. Since she originally bought the stock for $4000, the remainder was worth 0.25 * $4000 = $1000.

Selling this remainder for four times the purchase price means that Anna sold it for 4 * $4000 = $16000.

Answer:

4 cm.

Step-by-step explanation:

Area = pi r^2, so:

pi r^2 = 4 / pi

(pi)^2 r^2 = 4

r^2 = 4/ (pi^2)

r = 2/pi

Therefore, the circumference

= 2 pi r

= 2* pi * 2/pi

= 4

The expression becomes: p^(1/2) = p^(1/2 * 1) = p^(1/2) Now we can simplify p^(1/2) as p^1/2 which equals the square root of p.

The property of exponents that must be applied to the expression p^(1/2) to derive p as the result is the Power of a Power Property.

The Power of a Power Property states that when a power is raised to another power, the exponents are multiplied.

For instance, consider the expression p^(1/2). We can apply the Power of a Power Property to this expression as follows: p^(1/2) = (p^(1/2))^1 By applying the Power of a Power Property, the exponent (1/2) is multiplied by the exponent 1, giving a result of 1/2.

Therefore, the expression becomes: p^(1/2) = p^(1/2 * 1) = p^(1/2)Now we can simplify p^(1/2) as p^1/2 which equals the square root of p.

So we have derived p as the result using the Power of a Power Property.

In summary, we must apply the Power of a Power Property to the expression p^(1/2) to derive p as the result.

Step-by-step explanation:

To solve the equation 3,532.5 = (3.14)(r^2)(x/3) for the variable r, we can follow these steps:

Multiply both sides of the equation by 3/3 to eliminate the fraction:

3,532.5 * 3/3 = (3.14)(r^2)(x/3) * 3/3

This simplifies to:

10,597.5 = (3.14)(r^2)(x)

Divide both sides of the equation by (3.14)(x) to isolate the variable r:

10,597.5 / (3.14)(x) = (r^2)

Take the square root of both sides of the equation to solve for r:

r = sqrt(10,597.5 / (3.14)(x))

Therefore, the solution to the equation 3,532.5 = (3.14)(r^2)(x/3) for the variable r is:

r = sqrt(10,597.5 / (3.14)(x))

The number of sodas sold at the baseball game was 119, while the number of hot dogs sold was 72.

Let's assume the number of sodas sold as 'x' and the number of hot dogs sold as 'y'.

According to the problem, the total number of sodas and hot dogs sold is 191, so we can write the equation:

x + y = 191   ...(1)

The problem also states that the number of hot dogs sold was 47 less than the number of sodas sold. Mathematically, we can express this as:

y = x - 47   ...(2)

To find the values of x and y, we can solve the system of equations (1) and (2). Substituting equation (2) into equation (1), we have:

x + (x - 47) = 191

Simplifying the equation:

2x - 47 = 191

2x = 191 + 47

2x = 238

Dividing both sides by 2:

x = 238/2

x = 119

Substituting the value of x back into equation (2):

y = 119 - 47

y = 72

As a result, the total amount of sodas sold is 119, and the total amount of hot dogs sold is 72.

Three or more line segments that only intersect at their ends form closed, two-dimensional shapes known as polygons.

A polygon is a closed, two-dimensional shape with straight sides that is flat or plane. It has straight sides. Polygons are a different category that belongs to the category of two-dimensional figures because two-dimensional (2D) figures are flat because they lack volume.

Polygons are flat 2D shapes that have straight lines and all lines are closed, meaning that they don't have any disconnected lines. Polygons are a subcategory of 2D figures because they carry all traits of 2D figures but also have special ones of their own. Examples of polygons are squares, rectangles, and triangles. Examples of nonpolygons but still are 2D figures are circles, ovals, and any other flat shape.

The slope of the line that passes through the points (1, 6) and (1, 31) is, ∞

Slope is a ratio of change in y-coordinate w.r.t. change in x-coordinate. The net change in y coordinate is written as, Δy and the net change in x coordinate is written as, Δx.

So formula for the slope is,

m = change in y coordinate/change in x coordinate = Δy/Δx = y₂-y₁/x₂-x₁

Given that,

the line passes through the points, (1,6) and (1,31)

So, we can calculate slope for the line by using formula when two are given,

m =  y₂-y₁/x₂-x₁

x₁ = 1

y₁ = 6

x₂ = 1

y₂ = 31

m = 31-(6)/1-1

m ≈ ∞
