Need help (Just started circles) please explain how to solve every thing.

Answer:

The area of a parallelogram is given by the formula A = base x height. In this case, the base has a length of x meters, and the height is x - 1 meters. So we can write:

A = x(x - 1)

We are told that the area is 306 square meters, so we can set up an equation:

x(x - 1) = 306

Expanding the left side gives:

x^2 - x = 306

Bringing all the terms to one side gives a quadratic equation:

x^2 - x - 306 = 0

We can solve for x using the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

Here, a = 1, b = -1, and c = -306, so:

x = (1 ± sqrt(1 - 4(1)(-306))) / 2(1)

x = (1 ± sqrt(1 + 1224)) / 2

x = (1 ± sqrt(1225)) / 2

x = (1 ± 35) / 2

So x is either (1 + 35) / 2 = 18 or (1 - 35) / 2 = -17/2. Since x represents a length, it cannot be negative, so the value of x is 18 meters.

Therefore, the answer is x = 18.

Answer:

x = Approximately 4.92. (Tech: 4.923076923076923)

Step-by-step explanation:

To solve for x in the equation,

x - 1/4(12 - x) = x + 3(4 - x) - 2x

Expand the terms on the right side:

x - 1/4(12 - x) = x + 12 - 3x - 2x

Combine like terms:

x - 1/4(12 - x) = -3x + 12

Isolate x on one side of the equation:

1/4(12 - x) + 3x = 12 + x

Combine like terms:

1/4(12 - x) + 3x = 13

Distribute 3x:

1/4(12 - x) + 3x = 13

3x = 13 - 1/4(12 - x)

Multiply both sides by 4:

12x = 52 - (12 - x)

Combine like terms:

13x = 64

Finally, divide both sides by 13:

x = 4.923076923076923

So the value of x is approximately 4.92.

A percentage is a ratio, or a number expressed in the form of a fraction of 100. Percentages are often used to express a part of a total.

If we know that percentages are parts of 100, we can simply set the denominator as 100, and keep the numerator the same.

Converting this into a mixed number will look like this:

Therefore, the percentage 940% written as a mixed number is [tex]9\frac{4}{10}[/tex].

a) The new production rate is 1008 items per week.

b) The new unit cost is $63.

A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.

a) The new production rate can be calculated by increasing the old production rate of 900 items per week by 12%.

New production rate = 900 items/week + 12% of 900 items/week

New production rate = 900 items/week + (12/100) x 900 items/week

New production rate = 900 items/week + 108 items/week

New production rate = 1008 items/week

So, the new production rate is 1008 items per week.

b) The new unit cost can be calculated by reducing the old unit cost of $75 by 16%.

New unit cost = $75 - 16% of $75

New unit cost = $75 - (16/100) x $75

New unit cost = $75 - $12

New unit cost = $63

So, the new unit cost is $63.

The angle measures of each vertex of the garden are 53.13 degrees.

In Parallelogram ABCD, diagonals AC and BD intersect at point A = √7.

Angle is a geometric figure that can be described as the amount of rotation between two straight line or planes and angle is measured in degree with a full circle being 360°.

1. To determine the angle measures of each vertex of the garden, we must first calculate the angles formed by each side. For example, the angle formed by sides AB and BC can be found by using the inverse tangent function. The equation would be

arctan(BC/AB) = arctan (4/3) = 53.13 degrees.

The angles for the other sides can be calculated in the same way. We can then use the sum of angles theorem to calculate the angles at each vertex. Since the garden is an irregular shape, the angles at each vertex will be different.

2. In Parallelogram ABCD, diagonals AC and BD intersect at point A. To calculate , we can use the distance formula.

The equation would be = √((x2 – x1)2 + (y2 – y1)2).

For the coordinates given, we would have

= √((2 – 5)2 + (5 – 1)2)

= √(-9 + 16)

The solution to the figure shown is Option D.

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images.

The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

The equation for the rate of change of concentration is Δc/Δt, and this is equal to the rate of change of concentration over a given interval, -0.0680 m/s.

To calculate the final concentration, we must use the equation Δc = rate × time, where Δc is the change in concentration, and rate and time are the rate of change of concentration and the interval, respectively. Plugging in our values, Δc = -0.0680 m/s × 3.0 s = -0.204 m. This means that the final concentration of c is 2.700 m - 0.204 m, which is equal to 2.496 m.

To summarize, the rate of change of concentration equation is Δc/Δt = rate of change, and the equation to calculate the final concentration is Δc = rate × time. Plugging in the rate of change and interval, we get Δc = -0.0680 m/s × 3.0 s = -0.204 m, which gives us the final concentration of c at the end of the same interval as 2.496 m.

A frequency table would be useful for representing the age of students, majors, gender, and state of residence in a business statistics course.

A frequency table is a tabular representation of data that shows how often each value of a variable occurs. For example, a frequency table for the age of students in a business statistics course would list the different age groups and the number of students in each group. Similarly, a frequency table for the majors of students would list the different majors and the number of students in each major. A frequency table for gender and state of residence would also list the different categories (e.g. male/female or different states) and the number of students in each category.

In general, a frequency table is useful for representing categorical data, such as gender, majors, or state of residence, as well as numerical data, such as age, when the data is discrete or has a limited number of possible values.

The value of the trigonometry identity is tan(2x) = 4/7[√2]

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

cos(x) = 2√5/5 and 3π/2 < x < 2π

Start by calculating the sine function sin(x) using

sin(x) = √[1 - cos²(x)]

So, we have

sin(x) = √[1 - (2√5/5)²]

This gives

sin(x) = 1/10[√10]

The tangent is then calculated as

tan(2x) = (2sin(x)cos(x))/(cos²(x) - sin²(x))

This gives

tan(2x) = (2 * 1/10[√10] * (2√5/5))/(((2√5/5))² - (1/10[√10])²)

The area of the shaded region will be 3 square units.

One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.

Given that the total area of triangle XYZ is 8 square units. A and B are the midpoints of the sides XY and XZ.

Consider the half triangle XYC. The area will be half of the total triangle.

Area of  XYC = 4

( 1 / 2) x b x h = 4

b x h = 8

From the similarity property:-

h' / h = b' / b = 1 / 2

h' = h / 2 and b' = b / 2

Area of the triangle AXO:-

Area = 1 / 2 x h' x b '

Area = 1 / 2 x h / 2 x b / 2

Area = ( b x h ) / 8

Area = 8 / 8 = 1 square units

Area of shaded region =  Area of  XYC - Area of the triangle AXO

Area of shaded region =  4 - 1

Area of shaded region = 3 square units

Therefore, the area of the shaded region will be 3 square units.

By  simple interest , 2108 is the balance after 6 years.

What does compound and simple interest mean?

Simple interest and compound interest are the two methods that can be used to compute interest. The principal, or initial amount of a loan, is used to compute simple interest.

                                Compound interest is often referred to as "interest on interest" since it is computed using the main amount and the interest that has accrued over the course of previous periods.

annual simple interest = 4%

principal = $1700

 Time = 6 years

  interest = PRT/100

            = 1700 * 6 * 4/100

            =   408
