The dependent variable is "Bonding of veneer to cabinets" and the independent variable is "a cabinet shop".
What is a Dependent variable?In mathematical modeling, statistical modeling, and experimental sciences, there are dependent and independent variables. Dependent variables get their name because, during an experiment, their values are investigated under the presumption or requirement that they are dependent on the values of other variables due to some law or rule. A test score, for instance, could be a dependent variable because it could vary based on a number of variables, including how much you studied, how much sleep you got the night before the test, and even how hungry you were.So, in the given sentence, the dependent variable is "Bonding of veneer to cabinets" and the independent variable is "a cabinet shop".
Therefore, the dependent variable is "Bonding of veneer to cabinets" and the independent variable is "a cabinet shop".

Solve with work please. ;)
The inequality expression given as 2 - |6 + 12x| > -28 has a solution of -3 < x < 2
How to solve the inequality expression?From the question, the inequality is given as
2-|6+12x|>-28
Rewrite properly as
2 - |6 + 12x| > -28
Subtract 2 from both sides
- |6 + 12x| > -30
Divide both sides by -1
|6 + 12x| < 30
Remove the absolute bracket
So, we have the following representation
-30 < 6 + 12x < 30
Add -6 to all sides of the inequality
So, we have
-36 < 12x < 24
Multiply through by 1/12

draw two lines in the following trapezoid to create three equilateral triangles
A quadrilateral with at least one pair of parallel sides is called, in American and Canadian English, a trapezoid. In British and other forms of English, a (North American) trapezoid is called a trapezium. The transposition of these two terms was a result of an error in Charles Hutton's mathematical dictionary.
What is a trapezoid?In Euclidean geometry, a trapezoid is a convex quadrilateral by definition. The bases of the trapezoid are the parallel sides. If the remaining two sides are parallel, they are referred to as the legs (or lateral sides); if not, the trapezoid is a parallelogram, and there are two pairs of bases. As opposed to the particular examples below, a scalene trapezoid is a trapezoid without equal sides.
The Greek mathematician Euclid identified five different quadrilateral shapes, of which four had two sets of parallel sides (the square, rectangle, rhombus, and rhomboid in English) and one did not (a trapezia, meaning "a table," which comes from "four" and means "a foot; end, boundary, edge").
In his commentary on the first book of Euclid's Elements, Proclus (412–485) developed two varieties of trapezia: one pair of parallel sides, or a trapezium (v), divided into isosceles (equal legs), and scalene (unequal) Similar to how cuboid and rhomboid both mean "resembles," trapezia with no parallel sides is a trapezoid, trapezoeidé, or literally "trapezium-like."
English followed Proclus's arrangement until the late 18th century, when a prominent mathematical lexicon produced by Charles Hutton in 1795 endorsed a transposition of the terms without providing an explanation. Although this error was fixed in British English around 1875, it remained in American English till the present..

The perimeter of the image is 4 times as large as the perimeter of the pre-image.B The perimeter of the image is 8 times as large as the perimeter of the pre-image.C The perimeter of the image is 16 times as large as the perimeter of the pre-image.D The perimeter of the image is the same as the perimeter of the pre-image.
Answer:
A. The perimeter of the image is 4 times as large as the perimeter of the pre-image.
Explanation:
To answer this question, we use an example.
Given the pre-image:
• A square with side length 1 cm
,• Perimeter = 4 x 1 = 4cm
If the square is dilated by a scale factor of 4:
• Side length = 4cm
,• Perimeter = 4 x 4 =16cm
We see therefore that 'The perimeter of the image is 4 times as large as the perimeter of the pre-image.'
The correct choice is A.

How much tax did Loretta pay in total? You must show all your working.
Loretta would not have paid any taxes last year because her total earnings were below the €8625 threshold.
What is Percentage ?
A Percentage is a figure or ratio that is stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a measurement system.
The total amount paid in tax from Cary's last year earning is £9640
Total earning last year = €34 500
Tax on earnings :
First €3500 = 0%
€3500 to €10 500 = 25%
Earnings above €10 500 = 35%
Therefore, tax paid on €34 500 :
Tax percentage × amount earned
First €10 500 earned = (25% × 10,500) = 2625
Excess above €10 500 = (34500 - 10500) = 24000
25% × 24000 = 6000
Therefore, the total tax amount = €(2625 + 6000) = €8625

Brayden runs a farm stand that sells raspberries and grapes. Yesterday Brayden sold 44 pounds of raspberries and 43 pounds of grapes for a total revenue of $217. Today he sold 45 pounds of raspberries and 18 pounds of grapes for a total revenue of $144. Write a system of equations that could be used to determine the price of each pound of raspberries and the price of each pound of grapes. Define the variables that you use to write the system.
The system of equations that could be used to determine the price of each pound of raspberries and the price of each pound of grapes is: 44 x + 43 y = 217 , 45x + 18y = 144 . Each pound of peaches cost $2 and each pound of grapes cost $3
Equationx = price of each pound of peaches
y = price of each pound of grapes.
Given that yesterday, he sold 44 pounds of peaches and 43 pounds of grapes for a total revenue of $217
So 44 x + 43 y = 217 be equation 1.
Also given that today he sold 45 pounds of peaches and 18 pounds of grapes for a total revenue of $144.
So 45x + 18y = 144 equation 2.
Multiplying equation 1 with 18 gives us,
792x +774y = 3906
Multiplying equation 2 with 43 gives us,
1935x+774y = 6192
Solving these,
792x +774y = 3906
1935x+774y = 6192
---------------------------------------------
-1143 x=- 2286
x = 2286/ 1143
x = 2
Plug this value of x in equation 1 and solve for y, to get,
44 x + 43 y = 217
44 (2) + 43 y = 217
43 y = 217 − 88
43 y =129
y = 129/43
y = 3
