The scale factor of the transformation is 2.25
What is the scale factor of the transformationFrom the question, we have the following parameters that can be used in our computation:
Point H'(4.5, 6.75) is the result of dilating point H(2, 3)
This means that
The scale factor of the transformation = H'/H
Substitute the known values in the above equation, so, we have the following representation
Scale factor = (4.5, 6.75)/(2. 3)
Evaluate
Scale factor = 2.25
Hence, the scale factor is 2.25

How much total profit did he make by selling all
five pairs of running shoes?
Answer:
$80
Step-by-step explanation:
His buying cost for 1 pair of shoes: $49
His selling price for 1 pair of shoes: $65
His profit on selling 1 pair of shoes: $65 - $49 = $16
His profit on selling 5 pairs of shoes: 5 × $16 = $80

You are designing a rectangular poster to contain 48 in^2 of printing with a 3-in margin at the top and bottom and a 1-in margin at each side. What overall dimensions will minimize the amount of paper used?
To minimize the amount of paper used to create a rectangular poster with a given amount of printing and specific margins, you can use the formula for the area of a rectangle to determine the dimensions that will minimize the area of the poster.
In this case, the area of the poster must be at least 48 square inches to contain the printing, and the margins at the top and bottom must be 3 inches each, for a total of 6 inches. The margins at the sides must be 1 inch each, for a total of 2 inches. Therefore, the minimum area of the poster is 48 + 6 + 2 = 56 square inches.
To minimize the amount of paper used, we want to find the dimensions of the poster that will have the smallest possible area while still satisfying the constraints on the margins and the amount of printing. We can do this by using the formula for the area of a rectangle:
A = lw
where A is the area of the rectangle, l is the length, and w is the width.
In this case, we want to find the length and width that will minimize the area of the rectangle while still satisfying the constraints on the margins and the amount of printing. We can do this by setting the area of the rectangle equal to the minimum area we calculated above (56 square inches) and then solving for the length and width:
A = lw = 56
lw = 56
We can then use the constraints

what is the equation of the line that passes through the point(-6,-7) and has a slope of 1/3
Answer:
The equation of the line that passes through the point (-6, -7) and has a slope of 1/3 is:
x - 3y + 15 = 0
Step-by-step explanation:
The equation of a line in slope-intercept form is given by y = mx + b, where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).
To find the equation of the line that passes through the point (-6, -7) and has a slope of 1/3, we can use the point-slope form of a line:
y - y1 = m(x - x1)
Where (x1, y1) is a point on the line and m is the slope of the line.
Plugging in the given values, we have:
y - (-7) = (1/3)(x - (-6))
Which simplifies to:
y + 7 = (1/3)x + 2
Multiplying both sides by 3, we have:
3y + 21 = x + 6
Subtracting 21 and 6 from both sides, we have:
3y - x - 15 = 0
Therefore, the equation of the line that passes through the point (-6, -7) and has a slope of 1/3 is:
x - 3y + 15 = 0

What is a median of a triangle?A median of a triangle is a line segment that extends from a vertex of a triangle to the midpoint of the side opposite the vertex
The midpoints of the sides of the triangle = F, B, and D
The midpoint of EC = F
The midpoint of AC = B
Midpoint of AE = D
A. The lines CD, BE, and FA are called median lines
The point of intersection of the three median lines of a triangle is the centroid of the triangle.
The point G is called the centroid of the triangleB. The centroid of a triangle and center of gravity of the triangle are located at the same position in a uniformly dense triangle, therefore, G is the center of gravity, True, T
C. In the relationship of a median, we get;
AG = (2/3)·FA
GF = (1/3)·FA
Therefore, AG = 2·(GF)
GF = 0.5 × AG
GF = 0.5 × 10 = 5
GF = 5
D. DG = (1/3) × DC
Therefore; DC = 3 × DG
DG = 6, therefore, DC = 3 × 6 = 18

what is the hypotenuse???
To find the answer to this problem, you will need to use the Pythagorean Theorem.
What is the Pythagorean Theorem?
The Pythagorean Theorem is an equation that represents the summation of the sides of a right triangle.
a² + b² = c², where a is the shortest leg of the triangle, b is the longest leg and c is the hypothenuse.
You have been given a (12) and b (16)
First, plug your given information into the equation: 12² + 16² = c²
Next, simplify your equation by squaring both terms:
12² = 144
16² = 256
Then, add these two answers together: 144+ 256= 400
This leaves you with the equation: 400 = c²
To isolate the c as an individual term, take the square root of both sides:
[tex]\sqrt{400} = \sqrt{c^{2} }[/tex]
The above equation leaves you with the answer 20 = c, which is the hypothenuse

Lines c and d are parallel lines cut by transversal p.
Horizontal and parallel lines c and d are cut by transversal p. On line c where it intersects with line p, 4 angles are formed. Clockwise, from uppercase left, the angles are: 1, 2, 3, 4. On line d where it intersects with line p, 4 angles are formed. Clockwise, from uppercase left, the angles are: 5, 6, 7, 8.
∠2 is congruent to ∠6 based on corresponding angle theorem.
What is corresponding angle theorem?Corresponding angles are formed when two parallel lines are intersected by a transversal line.The corresponding angles theorem states that "when a line intersects two parallel lines, the corresponding angles in the two regions of intersection are congruent."Assume that A, B, and C are distinct lines. Then A and B are parallel if and only if the corresponding angles of intersection of A and C, as well as B and Care, are equal.So here ,
Since in this question they are corresponding angles of parallel lines cut by a transversal, they are ∠2 ≅ ∠6 according to the Vertical Angles Theorem.
The complete question is : "Lines c and d are parallel lines cut by transversal p. Horizontal and parallel lines c and d are cut by transversal p.

The ratio of heads to tails in the probability test is 2:1 or (D) 2/1.
What is the ratio?A ratio is a relationship or comparison between two numbers belonging to the same unit in order to determine how much larger one number is than the other.
For instance, if a test result is 7 out of 10, the ratio of the number of points earned to the total number of points is 7:10.

Given the logarithmic values as,
log₃ (t) = 5.44
log₃ (y) = 11.03
log₃ (z) = 7.74
Now, the value of the expression can be written as,
12 log₃ (z⁷ / y⁵t²)
= 12 { log₃ (z⁷) - [ log₃ (y⁵) + log₃ (t²) ] }
= 12 { 7log₃ (z) - [ 5log₃ (y) + 2log₃ (t) ] }

Where is Clare's mistake and what is the solution to the equation? 12(5 + 2y) = 4y- (5-9y) 72 + 24y = 4y -5-9y 72 + 24y = -5y -5 24y = -5y - 77 29y = -77 -77 y29

What is the distributive property of multiplication?In Mathematics, the distributive property of multiplication states that when the sum of two (2) or more addends are multiplied by a particular numerical value, the same result and output would be obtained as when each addend is multiplied respectively by the same numerical value, and the products are added together.
Based on the information provided above, we can logically deduce that Clare's mistake is at the second step because the product of 12 and 5 is equal to 60, rather than 72. Additionally, Clare did not distribute the negative sign to all the terms of the equation.
By applying the distributive property of multiplication to the given mathematical expression, we have the following:
12(5 + 2y) = 4y - (5 - 9y)
60 + 24y = 4y - 5 + 9y
60 + 24y = 13y - 5
24y - 13y = -5 - 60
