The base of a parallelogram has a length of x meters, and the height of the parallelogram is x - 1
meters. The parallelogram has an area of 306 square meters. What is the value of x?

34
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.

Solve for x. X-1/4(12-x)=x+3(4-x)-2x
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.

What is Reflection?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).

What is geometry?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

two different numbers are selected at random from {1, 2, 3, 4, 5} and multiplied together. what is the probability that the product is even?
Answer:
Probability of an even number product as requested = 7/10 = .7 = 70%
Step-by-step explanation:
Combinations of 2 digits from among 5 = 5!/(3!)(2!) = 10. Those combinations of 2 digits resulting in an even number product are even*even and even*odd. There are 2 even digits, (2,4) and 3 odd digits, (1,3,5).
Combinations of 2 even digits and 3 odd digits = 3*2 = 6. Combinations of 2 exact digits = 1*1 = 1. Thus, 6+1 = 7 different 2-digit products result in even numbers from among 10 possible 2-digit products.
Probability of an even number product as requested = 7/10 = .7 = 70%

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
the balance after 6 years = 1700 + 408

The value of the trigonometry identity is tan(2x) = 4/7[√2]
How to determine the trigonometry identityFrom 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)
Evaluate
tan(2x) = 4/7[√2]

over an interval of 3.0 s the average rate of change of the concentration of a was measured to be -0.0680 m/s. what is the final concentration of c at the end of this same interval if its concentration was initially 2.700 m?
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.

In Parallelogram ABCD, diagonals AC and BD intersect at point A = √7.
What is angle?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).
