which of the following verified that ABC is similar to DEF
Answer:
D
Step-by-step explanation:
The two triangles are similar by the property side angle side.
If two objects are having the same shape then they will be termed as similar. So in mathematics, if two figures have the same shapes, lines or angles then they are called similar.
In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other. The meaning of congruency is that the two shapes are similar as well as equal in size.
Here in the triangles, the angle is equal and the sides are dilated by factor two from 18 to 9. It means that the sides are similar to each other and the angle is the same.

Which function describes this table of values?
Answer:
[tex]y=\frac{4}{5}x[/tex]
Step-by-step explanation:
Equations in the given options are linear, so the table given represent a linear function.
Let the equation of the linear function is,
y = mx + b
Since this equation passes through (0, 0),
0 = m(0) + b
b = 0
Therefore, equation of the line will be,
y = mx
Slope of the line passing through (10, 8) and (5, 4),
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{8-4}{10-5}[/tex]
= [tex]\frac{4}{5}[/tex]
Therefore, equation of the line will be,
[tex]y=\frac{4}{5}x[/tex]

At a school carnival, 57 out of 95 tickets sold were early-admission tickets. What percentage
of the tickets were early-admission tickets?
Write your answer using a percent sign (%).
Answer:
60%
Step-by-step explanation:
57/95×100
hope this helps :)
Answer:
60%
Step-by-step explanation:
There is a total of 95 tickets, and 57 of them were early-admission tickets.
To find the percentage, we divide early-admission tickets by the total number of tickets, which is 57/95.
We can then simplify 57/95, getting 3/5, or 0.6, which is 60%.
1-1 Relations and Functions The following list details the numbers of tickets sold for a talent show: grade 9: 22; grade 10: 32; grade 11: 41; and grade 12: 30. What are the domain and range of this relation? A. domain: {22, 32, 41, 30}; range: {9, 10, 11, 12} B. domain: {9, 22, 10, 32}; range: {11, 41, 12, 30} C. domain: {9, 10, 11, 12}; range: {22, 32, 41, 30} D. domain: {11, 41, 12, 30}; range: {9, 22, 10, 32}
Answer:
[tex]Domain = \{9, 10, 11, 12\}[/tex]
[tex]Range = \{22, 32, 41, 30\}[/tex]
Step-by-step explanation:
Given
Grade 9: 22
Grade 10: 32
Grade 11: 41
Grade 12: 30
Required
Determine the domain and the range
The domain and range of a function is represented as thus (x,y)
From the given parameters;
[tex](x,y) = (Grade\ 9, 22), (Grade\ 10, 32) (Grade\ 11, 41), (Grade\ 12, 30)[/tex]
Remove "Grade" to represent as only digits
[tex](x,y) = (9, 22), (10, 32), (11, 41), (12, 30)[/tex]
Split to x and y values:
Where x = domain and y = range
[tex]Domain = \{9, 10, 11, 12\}[/tex]
[tex]Range = \{22, 32, 41, 30\}[/tex]

Use the graph to write an equation of the line. y= Question 2 Interpret the slope. The cost of the meal increases $0.20 for each dollar spent on the tip. The tip increases $0.20 for each dollar spent on the meal. The cost of the meal increases $0.50 for each dollar spent on the tip. The tip increases $0.50 for each dollar spent on the meal.
Answer:
$0.20
Step-by-step explanation:
Note that the graph does not have a vertical intercept other than (0, $0); it shows a proportional relationship. For each $1 increase in the cost of the meal, the tip increases by $0.20.
The equation of the line is:
[tex]y = 0.2x[/tex]
The slope is of $0.2, which means that the tip increases $0.20 for each dollar spent on the meal.
The equation of a line, in slope-intercept form, is:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem:
When x = 0, y = 0, thus the y-intercept is [tex]b = 0[/tex].When x = 10, y = 2, thus, considering that the slope is given by change in y divided by change in x:[tex]m = \frac{2 - 0}{10 - 0} = 0.2[/tex]
The equation of the line is:
[tex]y = 0.2x[/tex]
x is the cost of the meal, y is the tip, thus, the slope is of $0.2 means that the tip increases $0.20 for each dollar spent on the meal.

Answer:
y = 11
Step-by-step explanation:
We use the definition of Supplementary Angles and Adjacent Angles.
Step 1: Set up equation 1 (Definition of Supplementary Angles)
5x - 4 +7x - 8 = 180
Step 2: Solve for x
12x - 4 - 8 = 180
12x - 12 = 180
12x = 192
x = 16
Step 3: Plug in x
5(16) - 4
80 - 4
76°
Step 4: Set up equation 2 (Definition of Supplementary Angles)
76 + 9y + 5 = 180
Step 5: Solve for y
9y + 81 = 180
9y = 99
y = 11

Solve the equation for u.
Uw + uq=r
Answer:
u = [tex]\frac{r}{w+q}[/tex]
Step-by-step explanation:
Given
uw + uq = r ← factor out u from each term on the left side
u(w + q) = r ← divide both sides by (w + q)
u = [tex]\frac{r}{w+q}[/tex]
The equation uw + uq = r is solved for u will be written as u = r / (w + q).
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Answer:
There is 55.9 mL of acid in the solution.
Step-by-step explanation:
We have:
V = 354 mL
%(a): concentration of acid = 15.8 %
Hence, we can find the number of milliliters of acid as follows:
[tex] x = V*\%_{a} [/tex]
[tex] x = 354*\frac{15.8}{100} = 55.9 mL [/tex]
Therefore, there is 55.9 mL of acid in the solution.
