<1 and <2 are corresponding angles formed by two parallel lines and a traversal. if m<1=(3x-7)* and m<2=(x-1)*, find the value of 'x'.
Now we can solve for x by simplifying and isolating x on one side of the equation:
3x - x = 7 - 1
2x = 6
x = 3
Therefore, the value of x is 3.
How can you tell if two lines are parallel?In order to determine whether two lines are parallel, we must compare their slopes. Two lines are only considered parallel if and only if their slopes are equal. The conventional version of the equation is 2x - 3y = 4. Line q must have a slope of -2/-3 = 2/3 as a line with the equation Ax + By = C frequently has a slope of -A/B.
Since <1 and <2 are corresponding angles formed by two parallel lines and a traversal, they are congruent.
m<1 = m<2
(3x-7)* = (x-1)*
We can remove the asterisks on both sides of the equation since they represent the same unit of measurement for the angles.
3x - 7 = x - 1
Now we can solve for x by simplifying and isolating x on one side of the equation:
3x - x = 7 - 1
2x = 6
x = 3
Therefore, the value of x is 3.

Rice costs $x per kg.
Potatoes cost $(x+1) per kg.
The total cost of 12kg of rice and 7kg of potatoes is $31.70.
What is the cost of 1kg of rice?
Show your working kindly.
Answer:
x = 1.3
Step-by-step explanation:
cost of rice for 12kg = 12 * x ($x for each kg)
cost of potatoes for 7kg = 7 * (x+1)
total cost = 12 * x + 7 * (x+1) = 31.7
12x + 7x + 7 = 31.7
19x + 7 = 31.7
subtract 7 from both sides to isolate the variable and its coefficient
19x = 24.7
divide both sides by 19 to find x

when computing the correlation coefficient, what is the effect of changing the order of the variables on r?
Changing the order of the variables when computing the correlation coefficient has no effect on the value of "r" as it measures the strength and direction of the linear relationship between two variables.
The correlation coefficient denoted as "r", measures the energy and path of the linear dating between two variables. It ranges from -1 to one, in which -1 shows a perfect negative correlation, 0 indicates no correlation, and 1 shows an ideal advantageous correlation.
Whilst computing the correlation coefficient, the order of the variables does not have an effect on the cost of "r". This means that whether we calculate the correlation between variable x and variable y, or variable y and variable x, the resulting correlation coefficient will be equal.
That is due to the fact the correlation coefficient measures the degree of linear association between two variables, no matter which variable is taken into consideration because of the explanatory variable and which one is taken into consideration because of the response variable.
Therefore, the correlation between x and y could be similar to the correlation between y and x. But, it's important to observe that the translation of the correlation coefficient may additionally range depending on the research query and the context wherein it's far used.
The course of the connection among variables may also have one-of-a-kind implications relying on the specific state of affairs being analyzed.

Part B The numerator in the second fraction is closest to Choose... , so the fraction is nearest to Choose... . Part C The value of the expression can be estimated as Choose... + Choose... = Choose... . 7 / 7 5 of 7 Answered
Part A: The numerator in the first fraction is closest to 8, so the fraction is nearest to 1.
To see this, we can simplify the fraction 8/10 by dividing both the numerator and denominator by the greatest common factor, which is 2. This gives us:
8/10 = 4/5
Since the numerator of the simplified fraction is closest to 5, we can estimate that the value of the first fraction is nearest to 1.
Part B: The numerator in the second fraction is closest to 2, so the fraction is nearest to 1/3.
To see this, we can simplify the fraction 2/6 by dividing both the numerator and denominator by the greatest common factor, which is 2. This gives us:
2/6 = 1/3
Since the numerator of the simplified fraction is closest to 1, we can estimate that the value of the second fraction is nearest to 1/3.
Part C: The value of the expression can be estimated as 1 + 1/3 = 1 1/3.
To see this, we can add the two estimated fractions from parts A and B:
1 + 1/3 = 3/3 + 1/3 = 4/3
Since 4/3 is closer to 1 1/3 than any other whole number or fraction, we can estimate that the value of the expression is nearest to 1 1/3.
y is directly proportional to the square of x. find the percentage increase when x is increased by 5%
The change in percentage of y when x increases by 5% will be 25%
What is direct proportion?Direct proportion is a mathematical comparison between two numbers where the ratio of the two numbers is equal to a constant value.
Given that, y is directly proportional to the square of x. we need to find the percentage increase when x is increased by 5%
Since, Y varies directly as the square of x.
Therefore, the general equation to show the direct variation :-
Y = kx²
Let the value of x be 25
25 will be x as 100%. therefore when x is 100% the value of y will be
Y = 25²k
= 625k
Increasing the value of x by 5%,
(105x25)/100 = 26.25
Therefore, 105% of 25 = 26.25.
Applying the variation equation, we obtain
Y = (26.25)²k
= 689.0625k
We will find the percentage change in y caused by an increase of x by 5%
(689.0625x100)/625 = 110.25%
Therefore, to find the percentage change in y when x increases by 5% will be,
(110.25-100)% =10.25%
Hence, the change in percentage of y when x increases by 5% will be 25%

LQ and LR are complementary. The measure of LQ is 26° less than the measure of R. Find the measure of each angle
The measure of each angle if the measure of LQ is 26° less than the measure of R and, LQ and LR are complementary, is:
LQ = 32° LR = 58°What is the measure of each angle?We can solve this problem by using the definition of complementary angles and setting up an equation.
Since LQ and LR are complementary, we know that the sum of their measures is 90°. So we can write the equation:
LQ + LR = 90°
Next, we are told that the measure of LQ is 26° less than the measure of LR. We can write this as:
LQ = LR - 26°
Now we can substitute the expression for LQ into the first equation and solve for LR:
LR - 26° + LR = 90°
2LR = 116°
LR = 58°
Now we can plug this value back into the equation for LQ to find the measure of LQ:
LQ = 58° - 26°
LQ = 32°
So the measure of LQ is 32° and the measure of LR is 58°. These are the measures of the complementary angles.

What is an equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions written on the left and right sides. We have LHS = RHS (left-hand side = right-hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. A statement is not an equation if it contains no "equal to" symbol. It will be regarded as a phrase.
Given that
x⁻¹/(x⁻¹ + y⁻¹) + x⁻¹/(x⁻¹ - y⁻¹) = 2y²/(y² - x²)
Now solve the left-side expression:
L.H.S =
x⁻¹/(x⁻¹ + y⁻¹) + x⁻¹/(x⁻¹ - y⁻¹)
Now apply the formula a⁻¹ = 1/a:
= (1/x)/(1/x +1/y) + (1/x)/(1/x - 1/y)
= (1/x)/((x+y)/xy) + (1/x)/((y-x)/xy)
Now taking common (1/x)/(1/xy):
= (1/x)/(1/xy)[1/(x+y) + 1/(y-x)]
= (xy)/(x)[(y - x + x + y)/(x+y) (y-x)]
= y[2y/(x+y) (y-x)]

What are similar triangle?Similar triangles are the triangles that look similar to each other, but their sizes might not be exactly the same.
Given are two pairs of triangles, we need to determine if they are similar or not,
1) Δ ABC and Δ DEF :-
We know that, the sum of the interior angles of a triangle is 180°,
Therefore,
∠ A + ∠ B + ∠ C = 180°
60° + ∠ B + 79° = 180°
∠ B = 180°-139°
∠ B = 41°
In Δ DEF,
∠ F = 79° and ∠ E = 60°
That means,
∠ B ≅ ∠ F and ∠ E ≅ ∠ C
Since, we get two corresponding angles congruent,
Therefore, by the definition of similar triangles,
Δ ABC ~ Δ DEF, By AA rule.
2) Δ RTS and Δ MQP :-
∠ R ≅ ∠ M
RT / MQ = TS / QP = 4 / 5
RS / MP = 20 /26 = 10 / 13
That means,
RT / MQ = TS / QP ≠ RS / MP
Since, we have a condition in similarity, that if, in two triangles two corresponding sides are in equal ratio, and an angle between these sides are congruent then the triangle are similar by SAS rule,
But the angle R and angle M is not in between the sides having equal ratio,
Therefore, Δ RTS and Δ MQP are not similar.

A block of mass m slides down an inclined plane of inclination θ with uniform speed. The coefficient of friction between the block and the plane is μ. The contact force between the block and the plane is___
the contact force between the block and the plane is equal to the normal force, which is equal to the weight of the block (mg) multiplied by the cosine of the angle of inclination (θ). Therefore, the contact force between the block and the plane is mg cosθ.
The contact force between the block and the plane can be determined by analyzing the forces acting on the block.
First, we need to consider the forces acting on the block in the direction parallel to the inclined plane. Since the block is moving with uniform speed, the forces in this direction must be balanced. The forces in this direction are the force due to gravity acting down the inclined plane (mg sinθ) and the frictional force acting up the inclined plane (μmg cosθ). Therefore, we have:
mg sinθ = μmg cosθ
Simplifying this equation, we get:
μ = tanθ
This means that the coefficient of friction between the block and the plane is equal to the tangent of the angle of inclination.
Next, we need to consider the forces acting on the block in the direction perpendicular to the inclined plane. Since the block is not accelerating in this direction, the forces in this direction must also be balanced. The forces in this direction are the normal force acting up the inclined plane (N) and the force due to gravity acting vertically down (mg cosθ). Therefore, we have:
N = mg cosθ
So, the contact force between the block and the plane is equal to the normal force, which is equal to the weight of the block (mg) multiplied by the cosine of the angle of inclination (θ). Therefore, the contact force between the block and the plane is mg cosθ.

A TV that usually sells for $177. 21 is on sale for 15% off. If sales tax on the TV is 7%, what is the price of the TV, including tax?
The price of the TV, including tax, is $161.17 rounded to the nearest cent. To find the price of the TV including tax, we need to calculate the sale price of the TV after the 15% discount, add the sales tax, and then round to the nearest cent.
Here are the steps:
Calculate the sale price after the 15% discount:
Sale price = Original price - Discount amount
Sale price = $177.21 - (15% * $177.21)
Sale price = $150.63
Calculate the sales tax on the sale price:
Sales tax = 7% * $150.63
Sales tax = $10.54
Add the sales tax to the sale price:
Price including tax = Sale price + Sales tax
Price including tax = $150.63 + $10.54
Price including tax = $161.17
Therefore, the price of the TV, including tax, is $161.17 rounded to the nearest cent.

According to the model, -9 (7v + 9.7) = -63v - 87.3. The solution has been obtained by using area model.
What is an area model?
An area model is a rectangular graphic used in mathematics to multiply and divide two numbers or expressions. The length and breadth of the rectangle are determined by the factors, also known as the quotient and divisor.
We are given an expression as -9 (7v + 9.7).
Using area model,
-9 * 7v = -63v
Similarly,
-9 * 9.7 = -87.3
On combining both, we get
-9 (7v + 9.7) = -63v - 87.3
Hence, the value for the expression is -63v - 87.3.

The question is whether verbal reinforcement affects response rates. Subjects in
Group 1 were verbally reinforced every time they respond to the instructor’s
questions. Subjects in Group 2 were not. After 2 weeks, the two groups were
compared by gauging the number of students who raised their hand when
questions were asked. The following data were collected.
Group 1: 13, 15, 12, 17, 14, 14,
Group 2: 10, 12, 12, 11, 13, 9
The results of the study suggest that verbal reinforcement does affect response rates.
The mean number of students raising their hands for Group 1 (14.3) is significantly higher than the mean number of students raising their hands for Group 2 (11). This indicates that verbal reinforcement does lead to higher response rates.
Response rate is a measure of the proportion of people who respond to a given stimulus. For example, in the study mentioned above, the response rate for each group was measured by the number of students who raised their hands when questions were asked. A higher response rate indicates that more people are responding to a given stimulus.
