The 3 types of 3-dimensional coordinate systems are the x-axis, the y-axis, and the z-axis.
The Cartesian coordinates of a point in three dimensions are a triplet of numbers (x,y,z). The three numbers, or coordinates, specify the signed distance from the origin along the x,y, and z-axes, respectively.
The three axes intersect at the point called the origin. The x-axis is the horizontal line along which the wall to your left and the floor intersect.
The y-axis is the horizontal line along which the wall to your right and the floor intersect. The z-axis is the vertical line along which the walls intersect.
To locate the point (a, b, c), we can start at the origin O and move units along the x-axis, then b units parallel to the y-axis, and then c units parallel to the z-axis.

a cabinet holds shelves that are 12 1/2 inches apart. On one shelf, Katherine stacked a CD player that is 4 5/8 in. high on top of an amplifier that is 6 3/4 in. high. How much space was left above the CD player?
The space left above the CD player of height 4 5/8 in. stacked on the amplifier of height 6 3/4 in. in the cabinet which has shelves of 12 1/2 in. apart calculated as mixed fractions is 1 1/8 inches.
What is a mixed fraction?A mixed fraction is a fraction that is specified using the value of the quotient (the whole number part) and a fraction consisting of the remainder divided by the divisor.
The distance between the shelves of the cabinet = 12 1/12 inches
The height of the amplifier on a shelve of the cabinet on top of which Katherine stacks the CD player = 6 3/4 inches
The height of the CD player placed on top of the amplifier = 4 5/8 inches
The dimensions of the distance between the shelves and the heights of the CD player and amplifier are specified in fractions.
The space left above the CD player can be found in fractions as follows;
The combined height of the CD player and the amplifier is therefore;
[tex]H = 4\frac{5}{8} +6\frac{3}{4} = (4 + 6) + \left(\dfrac{5}{8}+\dfrac{3}{4} \right)[/tex]

[tex]10 + \dfrac{11}{8} = 10 + 1\dfrac{3}{8} = 11\frac{3}{8}[/tex]
The space above the CD player is therefore;
[tex]12\frac{1}{2} - 11\frac{3}{8} = 12 - 11 + \left(\dfrac{1}{2} - \dfrac{3}{8} \right) = 1 + \left(\dfrac{4 - 3}{8} \right)[/tex]

Dawson Christian Academy have 1200 people attend a music festival on either Friday or Saturday night if 60% attended Friday night how many people attended Friday night
There are 720 people (60 percent) attended a music festival on Friday night in Dawson Christian Academy.
What is the percentage?A percentage is a figure or ratio that shows a portion of one hundred. A dimensionless relationship between two numbers can be represented in a variety of ways, such as through ratios, fractions, and decimals. The symbol "%" is frequently written after the number to indicate percentages. Additionally, you can indicate them by adding "percent" or "pct" after the number.
Given that Dawson Christian Academy have people to attend a music festival is 1200
out of these people to attend a music festival on friday is 60%
No. of people to attend a music festival on friday is 60% of 1200
⇒ (60/100)*1200

A company produced 600 parts during first shift. The second shift produced 564 parts.
What is the percent change from first to second shift?
Reduced by 6%
In the first shift, they purchased 600 parts
the second time they purchased 564 parts
Percent = output/ total* 100here the second year they purchased a percentage
-> second shift/first shift*100 of the first year
564/600*100 ---> 564/6which gives 94%so it shows there is a reduction of 100-94 = 6%
As the second shift purchased 94 of them as compared to 100 in the first shift, So by this we can draw the inference that there is a drop of 6%.
Percent is the number out of 100 so here 36 parts are less than in the case of 600 which shows 6%. Moreover, the percentage gives a clear idea in terms of 100 which is more familiar as compared to their figures.

What is the image of a line?
Typically, a little dash is used to identify a point's reflection, such as A'. This is said with a "prime." As a result, line AB's reflection is known as A'B'. The reflection is referred to as line AB's "image."
Here,
We have to determine the formula of the image of a line.
We concluded that
The mirror's "reflection" of the specified point P causes it to appear at an equal distance away on the opposite side of the line. To see this, move point P. According to tradition, the "image" of point P is the reflection of point P across the line, which is designated by the term P' (pronounced "P prime").

The shape forms a pentagon. The value of y is 84°.
What is a polygon?
In geometry, a polygon is any closed curve made up of a series of line segments (sides) joined so that no two segments cross. Triangles (three sides), quadrilaterals (four sides), and pentagons are the simplest polygons (five sides).
The shape ABCDE forms a petagon.
The interior angle of a pentagon is 108°
The interior angle of a hexagon is 120°.
The ∠ABC is an angle of a regular hexagon, thus ∠ABC = 120°.
The ∠BCD is the angle of a regular hexagon, thus ∠BCD =120°.
The ∠BAE is an angle of a regular pentagon, thus ∠BAE=108°.
The ∠AED is an angle of a regular pentagon, thus ∠AED=108°.
The sum of all interior angle of a pentagon is 540°
Therefore,
∠ABC + ∠BCD + ∠BAE + ∠AED +∠EDC = 540°
120° + 120° + 108° + 108° + y = 540°
456° + y = 540°

What is the slope y =- 6?
The slope of the given expression is calculated using slope-intercept form. And the answer is 0.
How steep a line is or how much y climbs as x rises is determined by its slope. Slope compares changes to the y-axis, or the vertical axis, with changes to the x-axis, or the horizontal axis. The ratio of any two y values to any two x values can be used to calculate it.
By slope intercept, the standard equation is written as y=mx+b. Here, b is considered as the y-intercept, and m is considered as the slope. Then, the slope is calculated by comparing the given expression with this.
From the given expression, y = -6, we can tell the value of x is zero, the slope is also zero, and the y-intercept b is -6. Therefore, the required answer is 0.

How to convert XY coordinates to latitude and longitude in QGIS?
To convert XY coordinates to latitude and longitude in QGIS, you can use the "Layer > Save As" option in the main menu and select the "Lat Lon" option in the "CRS" (coordinate reference system) section or use the "Layer > Reproject Layer" option and select the destination CRS from the CRS list.
In QGIS, you can convert XY coordinates (also known as projected coordinates) to latitude and longitude (also known as geographic coordinates) using the "Layer > Save As" option in the main menu.
When you choose this option, a "Save Vector Layer As" dialog box will appear, in which you can select the "Lat Lon" option in the "CRS" (coordinate reference system) section.
Additionally, you can use the "Layer > Reproject Layer" option, if you have already loaded the layer in the map. By using this option you can select the destination CRS (Coordinate Reference System) from the CRS list.
It is important to note that to convert XY coordinates to latitude and longitude, QGIS needs to know the original projected coordinate system of the XY data, so it can accurately convert it to latitude and longitude. This information is called the "CRS" or "coordinate reference system" and is typically included with XY data in the form of a "PRJ" file or a metadata file.
