For length of 50 yards , the width is 60 yards, for length of 40 yards , the width is 75 yards, for length of 48 yards, the width is 62.5 yards , for length of 36 yards, the width is 83.33 yards, they are inversely proportional.

The formula for the area of a rectangle is: Area = Length * Width.

So, for the given case, we have:

Area = 3000 square yards

Length = 50 yards, 40 yards, 48 yards, or 36 yards

Therefore, the width of the plot in each case can be calculated as:

For Length = 50 yards,

Width = Area / Length

= 3000 / 50

= 60 yards

For Length = 40 yards,

Width = Area / Length

= 3000 / 40

= 75 yards

For Length = 48 yards,

Width = Area / Length

= 3000 / 48

= 62.5 yards

For Length = 36 yards,

Width = Area / Length

= 3000 / 36

= 83.33 yards

Therefore, the width of the plot depends on the length chosen and they are inversely proportional. When the length increases, the width decreases, and when the length decreases, the width increases.

according to the definition, two triangles are similar if their corresponding angles are congruent (identical) and corresponding sides are proportional (the ratio between the length of corresponding sides is equal for all pairs of corresponding sides, or, in other words, there is one scale factor for all 3 pairs of corresponding sides).

in fact, each criteria alone is sufficient.

if all 3 corresponding angles are identical between both triangles, the corresponding pairs of sides will be proportional.

if all 3 pairs of corresponding sides are proportional, then the corresponding angles are identical.

Answer: The relationship between the distance a car has traveled in miles, d, and the amount of gas left in the tank in gallons, x, can be represented by the equation:

d = r * m

where r is the fuel efficiency of the car in miles per gallon and m is the amount of gas consumed in gallons.

Since x is the amount of gas left in the tank, we can write:

x = m_0 - m

where m_0 is the initial amount of gas in the tank.

Combining the two equations, we get:

d = r * (m_0 - x)

This equation represents the relationship between the distance the car has traveled in miles, d, and the amount of gas left in the tank in gallons, x.

The percentage of sales tariff is 8.06%. Then the second item cost before the tariff will be $124.

Any product's quantity is given as if it were a percentage of one hundred. The ratio can be written as 100. The word "%" means "100%" in English. The sign for it is the letter "%".

The percentage is given as,

[tex]\text{Percentage (P) }= \dfrac{ \text{Final value - Original value}}{\text{ Original value }} \times 100[/tex]

An item that costs $310 before the tariff carries a $25 sales tariff. The sales tax % is then provided as,

[tex]\rm P = \left ( \dfrac{25}{ 310} \right ) \times 100[/tex]

P = 0.0806 x 100

P = 8.06%

The sales tax on a second object is $10. Then the second object cost before the tariff is given as,

⇒ $10 / 0.0806

⇒ $124

The percentage of sales tariff is 8.06%. Then the second item cost before the tariff will be $124.

Area of the parallelogram is 65 square meter.

Parallelogram is a type of polygon with four sides, four angles and four vertices. It is a type of Quadrilateral.

Opposite sides are parallel, and the opposite sides and opposite angles are equal.

Area of the parallelogram = Base × Height

From the figure,

Length of base = AB = 3 m + 10 m = 13 m

Height is also given as 5 m.

Area of the parallelogram ABCD = 13 m × 5 m

                                                      = 65 m²

Answer: 14π

Step-by-step explanation:

The area of a circle can be expressed as πr^2. In this case, the area is given as 49π m², so we can write:

πr^2 = 49π

Dividing both sides by π, we get:

r^2 = 49

Taking the square root of both sides, we get:

r = 7

The circumference of a circle is given by 2πr, so the circumference in this case would be:

C = 2π * 7 = 14π

So the circumference of the circle with an area of 49π m² is 14π meters.

The most likely production for a rainfall of 40 mm is 56.4 quintals.

From the question, we have the following parameters that can be used in our computation:

          Rainfall (mm) Production (quintals)

Mean           35                  50

S.D                5                    8

Coefficient of correlation = 0.8​

First, we need to calculate the regression equation, which is:

y = a + bx

Where

To calculate the intercept and slope, we use the following formulas:

b = r * (SDy / SDx)

a = Ymean - b * Xmean

Plugging in the given values, we get:

b = 0.8 * (8 / 5) = 1.28

a = 50 - 1.28 * 35 = 5.2

Therefore, the regression equation is:

Y = 5.2 + 1.28x

To find the most likely production for a rainfall of 40 mm, we plug in x = 40 into the regression equation:

Y = 5.2 + 1.28 * 40

Y = 56.4

Hence, the most likely production is 56.4 quintals.

Answer:

Step-by-step explanation:

First, we need to calculate the cost of each car after 60 months.

For the Ford Mustang:

Y = 275X + 2500

Y = 275 * 60 + 2500

Y = 16500

For the Dodge Charger:

Y = 250X + 1500

Y = 250 * 60 + 1500

Y = 15000

Next, we can compare the total cost of each car to determine which is the better deal.

In this case, the Dodge Charger is the better deal as it costs $1500 less than the Ford Mustang over the course of 60 months.

It's important to keep in mind that these calculations are based on the assumption that Junior will only make the minimum payments of $250 per month. If he decides to make larger payments or pay off the car early, the total cost of each car will be different.

Additionally, there may be other factors, such as the reliability and maintenance costs of each car, insurance costs, fuel efficiency, and driving experience, that should also be considered before making a decision. Junior should research and weigh all these factors before making a final decision.

In conclusion, the calculation of the cost of each car after 60 months is just one aspect of the decision-making process when buying a car. Junior should consider all relevant factors and weigh the pros and cons of each option before making a final decision.

A bell-shaped histogram is a type of graph that displays a normal distribution, which is a probability distribution that is symmetrical and has a characteristic bell shape.

The bell-shaped histogram is created by plotting the data on a horizontal axis and the frequency or probability on a vertical axis. The data points are grouped into intervals called bins, and the number of data points that fall into each bin is plotted as a bar. The bars are typically drawn adjacent to one another and connected with lines to create a continuous curve that represents the normal distribution.

The resulting histogram will have a characteristic bell shape, with a high point at the mean, and decreasing frequency or probability as the values move away from the mean in either direction. The width of the curve is determined by the standard deviation of the data, with wider curves indicating greater variation in the data.

The bell-shaped histogram is commonly used in statistical analysis to represent normally distributed data, such as the heights or weights of a population, test scores, or other measurements that tend to cluster around a central value with a predictable range of variation.

Step-by-step explanation:

y=9700(0.909)^x

# If the base of an exponential function is an element of the set (0,1) the function is decreasing as the value of 'x' is increasing from negative infinity to positive infinity.

the function y=9700(0.909)^x is an exponential function with a coefficient 9700 and base 0.909, as we increase the value of x from negative infinity to positive infinity, the value of y decreases. So the change between two consecutive 'y' values as 'x' increases indicate decay rather than growth.

And it can be written as y=9700(1-0.091)^x, therefore the percentage decrease is 9.1%

To find the percentage of yield in a calculator, you can follow these steps:

1. Determine the actual yield and the theoretical yield of the reaction. The actual yield is the amount of product that was actually produced in the reaction, while the theoretical yield is the amount of product that should have been produced based on the balanced chemical equation.

2. Divide the actual yield by the theoretical yield to find the decimal form of the percentage yield.

3. Multiply the decimal form of the percentage yield by 100 to find the percentage yield.

For example, if the actual yield of a reaction is 15 grams and the theoretical yield is 20 grams, the percentage yield would be:

(15/20) x 100 = 75%
