One unit means one thing. A unit rate means the ratio of something. Write this rate as a ratio with a denominator of 1. For example, if you run 70 meters in 10 seconds, on average you walk 7 meters in 1 second. Both reporting 70 meters in 10 seconds and 7 meters in 1 second are rates, but 7 meters in 1 second is the unit price. The unitary method is a method of finding the value of one unit and then finding the value of the required number of units.Suppose you go to the market to buy six apples. The trader tells you that he is selling 10 apples for 100 rupees. In this case the apple is the unit and the price of the apple is the value.
Total champagne available = 15 litres
1 litre = 1000 ml
15 litres = 15000 ml
Total = 15000 ml
Each guest had 2 glasses of 150 ml = 300 ml, which means each guest was served 300 ml of champagne
Total no of guests = Total champagne / champagne served to each
= 15000 / 300
= 50
50 guests were there at the party

The Length of the rectangle is: B. 6 2/3.
How to Find the Length of a Rectangle?The area of a rectangle is calculated as: Area = (length)(width). Therefore, if we known the area of a rectangle and its width, we can find the length of the rectangle using:
Length of rectangle = area of rectangle / width of rectangle.
Given the following:
Area of a rectangle = 21 and 2 over 3 square inches
Width = 3 and 1 over 4 inches
Length of the rectangle = 21 2/3 ÷ 3 1/4
Length of the rectangle = 65/3 ÷ 13/4
Length of the rectangle = 65/3 × 4/13

Which system of inequalities is represented by the given graph?
On the image in the quesitonw e cans ee the graph of a system of inequalities. There we can see two lines.
One of the lines has a positive slope and we can see that it is a solid line, and we also can see that the region below that line is shaded, so one of the inequalities is of the form:
y ≤ line with positive slope.
The whole opposite happens for the other line, it has a negative slope, it is dashed (so this time we use the symbols > or <) and the region shaded is above the line, so this time we have an inequality of the form:
y > line with negative slope.
Then the system of inequalities is:
y ≤ line with positive slope.
y > line with negative slope.
By looking at the options, the only one with this form is:
y > − 2x − 4

If a translation of T (2, -7) is applied to the triangle ABC as shown in the figure attached hereby for reference, and B (1, 5) gets repositioned to B', then the current coordinates of B' are (3, -2).
As per the question statement, a translation of T (2, -7) is applied to the triangle ABC as shown in the figure attached hereby for reference, and B (1, 5) gets repositioned to B'.
We are required to calculate the coordinates of B'.
To solve this question, we need to know what Translation (a, b) to (x, y) and (-a, -b) to (x, y) means. Translation (a, b) to (x, y) means the abscissa "x" is to be shifted to the right by "a" units while the ordinate "y" is to be shifted to the right by "b" units, i.e., after translation, the new coordinates become [(a + x), (b + x)]. On the other hand, Translation (-a, -b) to (x, y) means the abscissa "x" is to be shifted to the left by "a" units while the ordinate "y" is to be shifted to the left by "b" units, i.e., after translation, the new coordinates become [(a - x), (b - x)].
Here, as per the above mentioned concept, a translation of T (2, -7) if applied to the point B (1, 5), the new point B' will be at [tex][(1+2), (5+(-7)]=[3, (-2)][/tex].
Translation: In Coordinate Geometry, a translation is a repositioning of a point or a figure from one location to another location without changing its size, shape or orientation.Coordinates: The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional coordinate plane by using the horizontal and vertical distances from the two reference axesTo learn more about Translation, click on the link below.

Why 6:4 and 18:8 are not equivalent ratios?
Answers
The simplest form of the ratios are not the same, hence, the ratios 6:4 and 18:8 are not equivalent ratios
In order to show why the given ratios are not equivalent ratios, we need to express them in their simplest form as shown:
For the ratio of 6:4
6:4 = 6/4
simplify.
= 3/2
= 3×2/2×2
= 3/2
= 3:2
For the ratio of 18:8
18:8 = 18/8
simplify.
= 9/4
= 9×2/4×2
= 9/4
= 9:4

The graphs of the functions and relations gives;
4. The graph of y(x) = x² represents a function and the graph of y² = x represents a relation
5. In equation, y² = x, the value x = 9, gives two y–values y = 3 or -3, therefore y² = x is a relation rather than a function.
6. The domain and range are both [-8, 8]
7. From the equation,x = √(8 - y²), each x– value gives two y–values, therefore x² + y² = 8 is a relation not a function
What are the functions and relations?The given equations of the graphs are;
y(x) = x²y² = xWhere;
x = The input or independent variable
y = The output or dependent variable
In a function each input or value of x can give only one output or value of y, such that a vertical line drawn from each x–value crosses the graph only once.
Therefore;
The graph of y(x) = x², represent a function, given the each x–value has only one y–value, or the value of x determines the y–value.
The graph of y² = x represents a relation given that one x–value can give two y–values (a vertical line drawn at a point, x > 0, crosses the graph twice.
5. Let 9 represent the value chosen from the domain of both y(x) = x² and y² = x, we have;
y(9) = 9² = 81
Therefore, the x–value, x = 9 has only one y–value, which is 89Therefore, the equation, y(x) = x² is a function
In the relation, y² = x, we have;
y² = 9
y = ±3
Therefore, when x = 9, y = 3, or y = -3, which are two outputs or y–value for one input or x–value.
Which makes y² = x a relation rather than a function.
6. The equation of the graph is the equation of a circle, x² + y² = 8
Where;
8 = The square of the radius of the circle
(h, k) = (0, 0), the center of the circle is at the origin.
Therefore;
The coordinates of the edges of the circle on the x–axis are;
(-√8, 0), and (√8, 0)
The domain is therefore [-8, 8]
Similarly, the range, which are the possible y–values is also [-8, 8]
7. The equation x² + y² = 8, and therefore, the graph is not a function given that we have;
x² + y² = 8x = √(8 - y²)Given that y²y(x) = x²is always positive, each x - value gives two y-values, which does not conform with the mapping relationship of a function

Is the line through points (-3,2) and (4, -1) parallel to the line that contains the points (1,3) and (-2, -4)?
Are the two lines parallel?
How do you know?
Answers
Considering the expression of a line, they do not have the same value of m. So, the two lines are not parallel.
Linear equation o lineA linear equation o line can be expressed in the form y = mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Knowing two points (x1, y1) and (x2, y2) of a line, the slope m of said line can be calculated using the following expression:
m= (y2 - y1)÷ (x2 - x1)
Substituting the value of the slope m and the value of one of the points in the expression of a linear equation, y = mx + b, the value of the ordinate to the origin b can be obtained.
Parallel lineParallel lines are two lines that are always at the same distance from each other and that prolonged towards infinity never touch.
Two lines are parallel if they have the same slope and different y-intercepts. That is, they have the same value of m and different value of b.
Lines in this caseIn this case, you can calculated the slope of the two lines as:
Being (x1,y1)= (-3,2) and (x2,y2)= (4, -1), the slope m can be calculated as:
m= (-1 -2)÷ (4 - (-3))
Solving:
m= (-3)÷ 7
m= -3/7
Being (x1,y1)= (1,3) and (x2,y2)= (-2,-4), the slope m can be calculated as:
m= (-4 -3)÷ (-2 -1)
Solving:
m= (-7)÷ (-3)
m= 7/3
You can observe that they do not have the same value of m. Finally, the two lines are not parallel.

[tex]y=\frac{2}{5}x-3[/tex]
or
[tex]y+3=\frac{2}{5} (x-0)[/tex]
Step-by-step explanation:
Finding the Equation of a Line Given Two Points:In order to find the equation of a line, we must identify point (x,y) and slope (m). Slope formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Point-slope formula: [tex]y-y_1=m(x-x_1)[/tex]Slope-intercept formula: [tex]y=mx+b[/tex]We are given two points on Line A: (0,-3) and (5,-1). We can assign each integer to a variable in the slope formula (see above):
[tex]x_1=0[/tex]
[tex]y_1=-3[/tex]
[tex]x_2=5[/tex]
[tex]y_2=-1[/tex]
As we have identified point, we can now work to identify slope by substituting our points into the slope formula:
[tex]m=\frac{-1-(-3)}{5-0}=\frac{2}{5}[/tex]
Now that we have identified both point and slope for Line A, we can format these values in point-slope form. Substitute values into the formula:
[tex]y-(-3)=\frac{2}{5} (x-0)=y+3=\frac{2}{5}x[/tex]
Solve for [tex]y[/tex] to achieve an answer in slope-intercept form ([tex]y=mx+b)[/tex]:
[tex]y=\frac{2}{5} x-3[/tex]
