The value of x in the square is 5√2 centimetres.
How to find the side of a square?A square is a quadrilateral with 4 sides equal to each other. The square has side length 5 times x centimetres and the diagonal length is 50 centimetres.
Therefore, the side x can be found using Pythagoras's theorem as follows:
c² = a² + b²
where
c = hypotenusea and b are the other legsTherefore,
50² = (5x)² + (5x)²
2500 = 25x² + 25x²
2500 = 50x²
divide both sides by 50
x² = 2500 / 50
x² = 50
square root both sides of the equation
x = √50
x = √25 × 2
x = 5√2 centimetres

An open box area = 605 cubic feet
A square is a four-sided polygon which has it's all sides equal in length and the measure of the angles are 90 degrees. The shape of the square is such as, if it is cut by a plane from the center, then both the halves are symmetrical. Each half of the square then looks like a rectangle with opposite sides equal.
Area = [tex]l * b * h[/tex] (Equation - 1)
So,
We can substitute l , b , h values in the equation - 1,
605 = 5 * 5 * h
605 = 25 * h
605/25 = h
24.2 = h

If XV =27-2x and VZ =3x+2, find VZ and XZ
If XV =27-2x and VZ =3x+2, then the diagonal of parallelogram XZ = 34 units and VZ = 17 units.
What is a parallelogram?
A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size.
The length of line XV = 27 - 2x.
The length of line VZ = 3x + 2.
According to the properties of a parallelogram the diagonals bisect each other .
Hence, XV = VZ.

Why pixel value is 255?
The value 255 in pixels means the code for the image is white. Therefore, any image with 255 pixels means it is white color.
Pixel values are the numerical values that make up the matrix in which images are stored in computers. The byte image, the most popular pixel format, stores this number as an 8-bit integer with a possible value range of 0 to 255.
Normally, zero and 255 are considered to be black and white, respectively. The many colors of gray are composed of values in between. This has the tremendous benefit of allowing computers to operate with color values that can be stored in a tidy number of bytes.

Consider this system of equations 2/3 x + 3/5 y =12 (equation A) 5/2y - 3x = 6 (equations B)
The values of x and y that are solutions to the system of simultaneous equations are; y = 573/25 and x = 17.1
How to solve the system of linear equations?We are given the simultaneous equations;
²/₃x + ³/₅y = 12 -----(eq A)
⁵/₂y - 3x = 6 ------(eq B)
Multiply eq A by 9 and eq B by 2 to get;
6x + ²⁷/₅y = 108 -----(eq C)
5y - 6x = 12 ------(eq D)
Add eq C to eq D to get;
5y + ²⁷/₅y = 120
Multiply through by 5 to get;
25y + 27 = 600
25y = 600 - 27
25y = 573
y = 573/25
Thus;
5(573/25) - 6x = 12

In other words, they represent the range of values which a number may have taken had it not been rounded off or truncated.The numbers 10.3 and 10.5 are below and above, respectively (to 1 decimal place)
For the lower bound, we need to look halfway between 10.3 and 10.4 and for the upper bound, we need to look halfway between 10.4 and 10.5.
For the number to be rounded to 10.4 with one decimal point, it has to be between 10.35 and 10.45.

Describe the power function f(x)=x^5. What does it look like? Where does it cross the x- and y-axis?
f(x) = x⁵ – 8x⁴ + 16x³ at x = 4, does not cross the x-axis. at x = 0, crosses the x-axis. This relates to the x-axis end behavior of a graph of a function.
What is meant by Function?A relationship between a group of inputs and one output each is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output.A function, which generates one output from a single input, is an illustration of a rule. The photographer is Alex Federspiel.Y=X2 is an illustration of this. You only get one output for y if you enter anything for x. The fact that x is the input value leads us to say that y is a function of x.An input is connected to an output by a function. It resembles a device with an input and an output.Let's now find the roots of this function;
f(x) = x⁵ - 8x⁴ + 16x³
Let's factorize it first to get;
f(x) = x³(x² – 8x + 16)(x² – 8x + 16) is a perfect square trinomial and can be expressed as (x – 4)(x - 4).
Thus; f(x) = x³ (x – 4)(x - 4)
C) Since we have found the factorized form to be;
f(x) = x³ (x – 4)(x - 4)
The roots are at f(x) = 0;
The roots are; x³ = 0; (x – 4) = 0 ; (x - 4) = 0
This indicates that x=0 and x=4 are f(xroots. )'s x = 4
As a result, the graph will touch the x-axis but not the repeated root of 4, which indicates that the graph has a repeated root.
D) The graph will cross at x = 0 because it is a root and does not cross at x = 4.

What is the y-intercept of Y =- 10?
The y-intercept of Y = - 10 is -10.
If we draw the graph of the linear equation y = mx + c. The result is a line with m as the slope, and c as the y-intercept. This form of the linear equation y = mx + c is called the slope-intercept form, and the values of m and c are real numbers.
The slope, m, of the line represents the steepness of a line. This is also termed a gradient, sometimes. The y-intercept, b, represents the y-coordinate of the point where the graph of the line intersects the y-axis.
Now, if we equate the standard slope-intercept form of the equation with the given equation, we get
y = mx + c
y = - 10 = 0x -10
m = 0 and c = -10
As we know the c is the y-intercept which is equal to -10.

Horizontal lines called latitudes are used to measure distances north or south of the equator. Vertical lines known as longitudes are used to determine the west or east of the meridian in Greenwich, England. Latitude and longitude work together to help cartographers, geographers, and others find specific locations on the globe.

Sound decibel are not additive because humans listen to sound logarithmically and LaTrenda is correct
What is sound intensity of the two instrumentOsman is not correct in his claim that 88 + 75 decibels would be 163 decibels. The decibel unit is not an additive unit, meaning that when you add the decibel levels of two different sound sources, you do not simply add the decibel levels.
Instead, adding the decibel levels of two different sound sources together would give you the total sound pressure level (SPL) of the combined sound.
To calculate the SPL of the combined sound, you would need to add the intensities of the two sounds and then calculate the decibel level of the combined sound using the formula:
SPL (dB) = 10 log10 (I1/I0) + 10 log10 (I2/I0)
Where I1 and I2 are the intensities of the two sound sources and I0 is the reference intensity, which is the threshold of human hearing.
It would make more sense to add the intensities of the two sounds and then calculate the number of decibels, because the human ear perceives loudness of sounds logarithmically, not linearly.
So, LaTrenda would be correct in this scenario.
