The variable x has no true value in the similar shapes
How to solve for the variableFrom the question, we have the following parameters that can be used in our computation:
The figure
Using the figure, we have the following ratio
3x : 4x - 1 = 4x - 1 : x² - x - 2
Factorize
3x : 4x - 1 = 4x - 1 : x² + x - 2x - 2
So, we have
3x : 4x - 1 = 4x - 1 : x(x + 1) - 2(x + 1)
This gives
3x : 4x - 1 = 4x - 1 : (x - 2)(x + 1)
Express as fraction
3x/(4x - 1) = (4x - 1)/(x - 2)(x + 1)
So, we have
3x(x - 2)(x + 1) = (4x - 1)(4x - 1)
Using a graphing tool, we have
x = undefined

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base, and Hypotenuse.
To find the height of the paperweight, we can use the Pythagorean Theorem, which relates the lengths of the sides of a right triangle.
In this case, the height of the paperweight, which is the unknown side, forms a right triangle with one of the slant heights and half the length of the square base, as shown in the diagram below:

How to Calculate Z Scores?
The formula for calculating the z-score is z = (x-μ)/σ.
where x is the raw score, μ is the population mean, and σ is the population standard deviation. As the formula suggests, the Z-score is simply the raw score minus the population mean divided by the population standard deviation.
A positive Z-score indicates that the raw score is higher than the average. For example, a z-score of +1 is one standard deviation above the mean.
A negative z-score indicates that the raw score is below average. For example, a Z-score of -2 is two standard deviations below the mean.
Another way to interpret z-scores is to create a standard normal distribution (also known as the z-score distribution or probability distribution).

What is 6 ft 6 ft in inches?
We converted the measurement of 6 ft x 6 ft to inches using a conversion factor of 12 inches per foot, resulting in a total area of 5,184 square inches.
Measurement is an important aspect of our daily lives, and it involves quantifying the size, length, or dimensions of an object or space. Different units of measurement are used to express the size or length of an object, depending on the context or purpose.
The measurement of 6 ft x 6 ft is the size or area of a square-shaped object, where each side is 6 ft long. To convert this measurement to inches, we need to use a conversion factor that relates feet to inches. One foot is equal to 12 inches, so we can multiply each side of the square by 12 to get the corresponding measurement in inches.
6 ft x 12 inches/ft = 72 inches
Therefore, the measurement of 6 ft x 6 ft in inches is 72 inches x 72 inches, which equals 5,184 square inches. This means that if we had a square-shaped object with sides measuring 6 feet, the total area of the object would be 5,184 square inches.

How to convert 7 into a decimal
The value of 7 after converted into decimals is 7.0.
To convert the integer 7 into a decimal, you simply need to place a decimal point after the 7 and add a zero to the right of the decimal point. This is because in the decimal system, each digit to the right of the decimal point represents a power of 10, starting with 10^-1 or 0.1.
Therefore, 7 can be represented as 7.0 in decimal form. Note that trailing zeros to the right of the decimal point do not change the value of the number. In other words, 7, 7.0, and 7.00 all represent the same value in decimal form.

Describe Right Angle Triangle?A right-angle triangle is a type of triangle that has one angle that measures exactly 90 degrees (a right angle). This angle is formed where the two shorter sides of the triangle meet. The side opposite to the right angle is called the hypotenuse, while the other two sides are called the legs.
The Pythagorean theorem is a fundamental relationship that applies to right-angle triangles. It states that the sum of the squares of the two shorter sides (legs) of a right-angle triangle is equal to the square of the hypotenuse. In other words, a² + b² = c², where a and b are the lengths of the legs, and c is the length of the hypotenuse.
Right-angle triangles are commonly used in mathematics, physics, engineering, and many other fields. They can be used to solve problems related to distances, heights, and angles, and are a fundamental building block in many geometric constructions.
The special properties of right-angle triangles also make them useful in practical applications, such as in construction, where they can be used to measure angles and distances accurately, and in navigation, where they can be used to calculate distances between two points using trigonometric functions.
In triangle ABC, we know that angle BAC is 30 degrees, and angle ABC is a right angle. Therefore, angle ACB is 60 degrees (since the angles in a triangle add up to 180 degrees).
We can use the sine and cosine ratios to find the values of x and y. Using the definition of sine and cosine:
sin(30) = opposite / hypotenuse
cos(30) = adjacent / hypotenuse
In this case, AB is the adjacent side to angle BAC, and AC is the hypotenuse. Therefore:
cos(30) = AB / AC
Substituting the given values, we get:
cos(30) = x / y
Solving for x, we get:
x = y cos(30)
Plugging in y = 11, we get:
x = 11 cos(30)
Using a calculator, we can find that cos(30) = √3 / 2, so:
x = 11 × √3 / 2
x = 11√3 / 2
Therefore, the answer is A: x = 22√3 / 2 and y = 11. We can simplify x by multiplying both the numerator and denominator by 2 to get x = 22√3.

The sea otters are fed 1/4 as much fish as the dolphins, which means they are fed:
(1/4) x 6 = 6/4 = 3/2 buckets of fish each day.

Solve the simultaneous equation 1÷x + 1÷y =5, 1÷y - 1÷x =1
Therefore, the solutions to the simultaneous equation are (x, y) = ((5 + √(21))/2, (5 - √(21))/2) and (x, y) = ((5 - √(21))/2, (5 + √(21))/2).
To solve the simultaneous equation 1÷x + 1÷y = 5, 1÷y - 1÷x = 1, we can use the substitution method. Here are the steps to solve the equation:
1. Rearrange the first equation to get 1÷y = 5 - 1÷x
2. Substitute this into the second equation to get 1÷(5 - 1÷x) - 1÷x = 1
3. Multiply both sides by x(5 - 1÷x) to get x - (5 - 1÷x) = x(5 - 1÷x)
4. Simplify and rearrange to get x² - 5x + 1 = 0
5. Use the quadratic formula to solve for x: x = (-(-5) ± √((-5)² - 4(1)(1)))÷(2(1)) = (5 ± √(21))/2
6. Substitute the values of x back into the first equation to find the corresponding values of y: y = 1÷(5 - 1÷((5 + √(21))/2)) = (5 - √(21))/2 and y = 1÷(5 - 1÷((5 - √(21))/2)) = (5 + √(21))/2
