Answer:

42.9%

Step-by-step explanation:

The total number of votes between Carlton and Will is [tex]60 + 45 = 105[/tex].

If we put Carlton's votes in a fraction over the total number of votes, we get [tex]\frac{45}{105}[/tex].

So, if we now multiply this fraction by 100, we will get the percentage amount:

[tex]\frac{45}{105} * 100 = 42.9[/tex]

This means that to 1 decimal place, the percentage of votes that Carlton received is 42.9%.

Answer:

Carton receive:

42.86%    (aprox)

Step-by-step explanation:

45 + 60 = 105

total votes = 105

Carlton received 45 votes

then:

45/105 = 0.4286       (aprox)

0.4286*100 = 42.86%

Answer: For the first box it is parallel, for the second box it is the corresponding angles theorem, the third is NYM, and the last one is AA.

Step-by-step explanation: 1.) Since line NM has an arrow on it's line and XZ has an arrow on it's line, that means that those two line are parallel to each other. 2.) Since both triangle contain the same transversal line (NY) and the corresponding angles theorem states that if a transversal intersects parallel lines, the corresponding angles are congruent. From this we can conclude that this means that the angle <YXZ has is congruent to the angle <YNM. Therefore we use the corresponding angles theorem. 3.) Answer 2 basically answers box number three but since we concluded that Angles of <YXZ and <YNM are both congruent <NYM would be your answer its just flipped. 4.) We use the AA theorem, because the AA theorem states that if an angle or angle(s) of one triangle is congruent to another angle/angle(s) of another triangle, then the triangles are similar (congruent). Therefore we would use the AA theorem.

By the way this is the answer for EDGE in 2023

the total area of the figure A = 144.5 cm²

First, the area of a rectangle of length L and width W is:

A = W*L

Here we have:

L = 13cm

W = 9cm

Then the area is:

A = 9cm*13cm = 117 cm²

For a triangle of height H and base B, the area is:

A = B*H/2

Here the base measures 11cm, and the height is:

H = 13cm - 8cm = 5cm

So the area of the triangle is:

A= 5cm*11cm/2 = 27.5cm²

Then the total area of the figure is:

area =  27.5cm² +  117 cm² = 144.5 cm²

Answer:

(h, k )

Step-by-step explanation:

given the standard form of an absolute function

f(x) = a| x - h | + k , then

vertex = (h, k )

The standard form of an absolute value function is f(x) = a|x - h| + k, where (h,k) is the vertex of the absolute value function.

The correct option is (h,k).

The term "function" refers to a relationship between a set of inputs and outputs. Just one output is connected to each input in a function, which connects inputs in that manner. Every function has a domain, co-domain, and range.

In general, the standard form of an absolute value function is given as:

f(x) = a |x - h| + k

where:

a is a non-negative constant that determines the shape and direction of the V-shaped graph of the absolute value function

h is the horizontal shift of the graph of the function from the origin (if h > 0, the graph shifts to the right; if h < 0, the graph shifts to the left)

k is the vertical shift of the graph of the function from the origin (if k > 0, the graph shifts up; if k < 0, the graph shifts down)

The vertex of the absolute value function is the point where the graph changes direction, that is, the point where the graph changes from sloping downwards to sloping upwards or vice versa.

Since the vertex is the point of the absolute value function where the graph changes direction, it lies at the center of the V-shaped graph. Thus, the vertex is located at the point (h,k).

Therefore, in the standard form f(x) = a |x - h| + k, (h,k) represents the coordinates of the vertex of the absolute value function.

Answer:

A linear inequality that is represented by the graph include the following: C. y > 2/3(x) + 3.

In Mathematics, there are two (2) main rules that are generally used for writing and interpreting an inequality or system of inequalities that are plotted on a graph and these include the following:

here, we have,

The line on a graph should be a solid line when the inequality symbol is (≥ or ≤).

The line on a graph should be a dashed (dotted) line when the inequality symbol is (> or <).

The line on a graph should be shaded above the line when the inequality symbol is (>).

Since the line on this graph was shaded above the line and it passes through the point (0, 3), it ultimately implies that 3 is part of its solution and as such, it is represented by this inequality equation:

y > 2x/3 + 3.

The value of x is 2 because the centroid of the triangle divides each median in the ratio of 2:1 option (C) is correct.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

The solution of the system of equations is the point (-6, 6), so the correct option is B.

Here we have the system of equations:

2x + 3y = 6

x + 3y = 12

First, let's write these two lines in the slope-intercept form:

y = (6 - 2x)/3 = 2 - (2/3)*x

y = (12 - x)/3 = 4 - (1/3)*x

Now, because "y" is the represents the same variable in both equations, we can write:

2 - (2/3)*x = y = 4 - (1/3)*x

Now we can solve that for x.

2 - (2/3)*x =  4 - (1/3)*x

2 - 4 = (2/3)*x - (1/3)*x

-2 = (1/3)*x

3*(-2) = x = -6

Now, to get the y-value of the solution we can evaluate any of the two lines in x = -6, evaluating the first we get:

y =  4 - (1/3)*x = 4 - (1/3)*(-6) = 4 + 2 = 6

Then the solution of the system is the point (-6, 6). Then the correct statement is B:

"The values of x= -6 and y= 6 satisfy both the equations; therefore, (-6, 6) is the solution."
