Answer:

5.46 kilograms or 6.6 kilograms  

Step-by-step explanation:

Assume that 2 5 in your question has two possible meaning:

Let divide 9.1 kilograms into 5 equal part

=> 1 equal part =  9.1 / 5 = 1.82 kilograms  

Because 2/5 of this weight is apples, so the weight of apples accounted for 2 equal parts

=> the weight of apples is: 2*1.82 kilograms  = 3.64 kilograms

=>  the weight of pears is: 9.1 kilograms - 3.64 kilograms = 5.46 kilograms

Given the total weight is 9.1 kilograms

=>  the weight of pears is: 9.1 kilograms - 2.5 kilograms = 6.6 kilograms

Final answer:

To find the amount of pears sold, calculate two-fifths of the total weight for the apples and subtract this from the total weight. The farmer sold 5.46 kilograms of pears.

Explanation:

The student has asked a question that requires understanding of basic fractions and weight calculation in a real-life context, specifically within a farmer's market scenario. To solve the problem, we note that the total weight of apples and pears sold is 9.1 kilograms. If two-fifths (2/5) of this weight is apples, then to find the weight of pears, we first calculate the weight of apples and then subtract this from the total weight to get the weight of pears.

Step 1: Calculate the weight of apples by multiplying the total weight by the fraction that represents apples. This is 2/5 of 9.1 kg.

Step 2: Subtract the weight of the apples from the total weight to find the weight of pears.

Here are the calculations:

Weight of apples = (2/5) × 9.1 kg = 3.64 kg

Weight of pears = Total weight - Weight of apples = 9.1 kg - 3.64 kg = 5.46 kg

Therefore, the farmer sold 5.46 kilograms of pears at the farmer's market.

Answer:

If the price before depretiation be P and price after depreciation be Pt..

The eqn would be,

Pt=P(1-12/100)^t

Hope it helps!!

Final answer:

The function to represent the value of a car over time, with an initial value of $9000 and depreciating at 12% per year, is V = 9000(1 - 0.12)^t. This exponential decay function calculates the car's value at any time t years after purchase.

Explanation:

The question asks for a function to represent the value of a car over time, given that the car was purchased for $9000 and depreciates at a rate of 12% per year. To model this, we can use an exponential decay function. The general form of an exponential decay function is V = P(1 - r)^t, where V represents the value of the car at time t, P is the initial purchase price, r is the rate of depreciation, and t is the time in years.

Substituting the given values into the formula, we get V = 9000(1 - 0.12)^t. This function can be used to calculate the value of the car at any given time t years after the purchase. The rate of depreciation (12%) and the initial purchase price ($9000) are the critical factors that determine the car's value over time.

Answer:

$990 per unit.

Step-by-step explanation:

The Unit Cost (C) and Unit Revenue R from the production and sale of x units are related by the function:

[tex]C=\dfrac{R^2}{220000} +3221[/tex]

We are required to find the rate of change of revenue per unit when the cost per unit is changing by $9 and the revenue is ​$1,000.

Rate of Change of C,

[tex]\dfrac{dC}{dt}=\dfrac{R}{110000} \dfrac{dR}{dt} \\\dfrac{dC}{dt}=\$9, R=\$1000\\9=\dfrac{1000}{110000} \dfrac{dR}{dt}\\\dfrac{dR}{dt}=9 \div \dfrac{1000}{110000}\\=9 X \dfrac{110000}{1000}\\\dfrac{dR}{dt}=\$990 $ per unit$[/tex]

The Revenue is changing at a rate of $990 per unit.

The problem is solved by first finding the derivative of the given equation to determine the rate of change. Given that the cost per unit is changing by $9, we substitute this in the derivative equation to get the revenue. Real-world applications of such problems help understand the concepts of marginal revenue and marginal cost.

As per the equation C = R2/220000 + 3221, we first need to find the derivative to determine the rate of change. So, C'(R) = 2R/220000 where C' represents the derivative of the cost with respect to revenue.

Given that the cost per unit is changing by $9, we can represent this as C' = 9 and solve for R using the derivative equation. Hence, R = sqrt(220000 * 9 / 2) = $1000. Therefore, the rate of change of revenue per unit when the cost per unit is changing by $9 and the revenue is ​$1,000 is found by substituting the revenue value into derivative equation.

These types of problems demonstrate how rates of change can be evaluated using calculus concepts in real-world applications such as understanding marginal revenue and marginal cost in economics and business studies.

The answer is -4x.

Step-by-step explanation:

You can just substract easily by writing 7-3 but remember to add negative to the final value as 3 is smaller than 7 and lastly, you only have to add x to the final answer.

The probability of not getting a '3' when a fair die is rolled four times, rounded to the nearest thousandth, is approximately 0.482.

In a fair die, the probability of getting any one number, such as a 3, is 1/6 because a die has 6 possible outcomes (1 through 6). So, the probability of not getting a 3 is 5/6. If the die is rolled four times, the probability of not getting a 3 on each roll is (5/6)^4. To find this, multiply 5/6 by itself 4 times. The result is approximately 0.482, or rounded to the nearest thousandth, 0.482. So, "the probability of not getting a 3 on four rolls of a die to the nearest thousandth is 0.482."

Answer:

x = 50.5°

Step-by-step explanation:

∠ BDC and ∠ BDA are adjacent and supplementary, thus

∠ BDC = 180° - 78° = 102°

Calculate ∠ BCD using the Sine rule in Δ ABC, that is

[tex]\frac{5.6}{sinC}[/tex] = [tex]\frac{9.3}{sin50}[/tex] ( cross- multiply )

9.3 × sinC = 5.6 × sin50° ( divide both sides by 9.3 )

sinC = [tex]\frac{5.6sin50}{9.3}[/tex] ≈ 0.4613, thus

C = [tex]sin^{-1}[/tex] (0.4613 ) ≈ 27.5°

The sum of the 3 angles in Δ BCD = 180°, thus

x = 180° - (102 + 27.5)° = 180° - 129.5° = 50.5°

The angle x is also 52 degrees.

To find the measure of angle x in triangle ABC, we can use the fact that the sum of the angles in a triangle is always 180 degrees.

Given that angle A is 78 degrees and angle B is 50 degrees, we can find angle C using the following equation:

Angle C + Angle B + Angle A = 180 degrees

Angle C + 50 degrees + 78 degrees = 180 degrees

Now, subtract the known angles from 180 degrees to find the measure of angle C:

Angle C = 180 degrees - (50 degrees + 78 degrees)

Angle C = 180 degrees - 128 degrees

Angle C = 52 degrees

Now that we know angle C is 52 degrees, we can use the fact that the angles in a triangle add up to 180 degrees to find angle x:

Angle A + Angle B + Angle x = 180 degrees

78 degrees + 50 degrees + Angle x = 180 degrees

Now, subtract the known angles from 180 degrees to find angle x:

Angle x = 180 degrees - (78 degrees + 50 degrees)

Angle x = 180 degrees - 128 degrees

Angle x = 52 degrees

So, angle x is also 52 degrees.

Final answer:

The area of the rectangular room with length 2 feet longer than the width can be expressed as w^2 + 2w square feet, where w represents the width of the room.

Explanation:

Barry needs to calculate the area of a rectangular room where the length is 2 feet longer than the width. If we denote the width as w, then the length will be w + 2 feet. The area of a rectangle is found by multiplying the length by the width.

Therefore, the expression for the area in terms of the width will be:

Area = width × length

Area = w × (w + 2 feet)

Area = w² + 2w square feet

This expression will give us the area of the rectangle in square feet.

To eliminate the parameter and find the Cartesian equation of the curve x = 7sin⁡θ,y = cos2⁡θ, we can express x in terms of θ, rearrange the equation, and substitute it into the other equation to eliminate the parameter θ. The resulting equation 2(x/7)² + y - 1 = 0 represents the Cartesian equation of the curve.

To eliminate the parameter and find the Cartesian equation of the curve, we can express x in terms of θ using the given equation x = 7sin⁡θ. Rearranging this equation, we get sin⁡θ = x/7. Similarly, we can express y in terms of θ using the given equation y = cos2⁡θ, which can be rewritten as cos⁡(2θ) = y.

Now we can use the trigonometric identity cos⁡(2θ) = 1 - 2sin²⁡θ to eliminate θ from the equations. Substituting this identity into the second equation, we get 1 - 2(sin⁡θ)² = y.

Simplifying this equation, we have 2(sin⁡θ)² + y - 1 = 0. Finally, we can express sin⁡θ in terms of x using the equation sin⁡θ = x/7, and substitute it into the simplified equation to eliminate θ. This gives us 2(x/7)² + y - 1 = 0, which represents the Cartesian equation of the given curve.
