A set of steps which a student should follow to prove that the diagonals of the square are perpendicular to each other include the following: A) Step 1: Find the slope of diagonal PR and slope of diagonal QS Step 2: Show that m₁ × m₂ = -1.
How to determine whether the quadrilateral is a square by using slope?In order for a quadrilateral to be a square, the two (2) pairs of its sides must be equal (congruent) and perpendicular to each other. Therefore, we would have to calculate the slope of each side by using this mathematical expression:
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Where:
x and y represents the data points or side lengths of a quadrilateral.
For side PQ, the slope is given by:
Slope (m) = (8 - 4)/(6 - 2)
Slope (m) = (4)/(4)
Slope (m) = 1.
In Mathematics, a condition that must be met for two (2) lines or side lengths to be perpendicular is given by:
m₁ × m₂ = -1
1 × m₂ = -1
m₂ = -1
Slope (m₂) = -1

Answer: x = Answer
The measure of value of x for the given set of parallel lines is found as:
x = 34.
Define the term alternate exterior angles?The pair of angles that lie outside the parallel lines yet on the other side of the transversal are known as alternate exterior angles. When two lines are split in a third line, called transversal, the phrase alternating exterior angles is frequently used. According to the Alternative Exterior Angles Theorem, pairs of alternative exterior angles become congruent if any lines k and l are parallel.From the definition of alternate exterior angles:
3x + 1 = 103°
3x = 103 - 1
3x = 102
x = 34
Thus, the measure of value of x for the given set of parallel lines is found as: x = 34.

you have a fair coin and want to calculate the probability that if you flip the coin 20 times, you will get at least 14 heads. what is the probability that you will get heads more than 14 times?
The probability of getting at least 14 heads when flipping a fair coin 20 times is 0.25.
This can be calculated using the binomial distribution formula which states that the probability of obtaining exactly x successes in n trials is given by
P(x) = (n choose x) * p^x * (1-p)^(n-x),
where n is the total number of trials, p is the probability of success, and x is the number of successes.
For this problem, n=20, p=0.5, and x=14, so the probability of getting at least 14 heads is P(x) = (20 choose 14) * 0.5^14 * 0.5^6 = 0.25.

The equation for your savings account can be represented as:
y = 50 + 10x
The equation for your friend's savings account can be represented as:
y = 25 + 10x
where x is the number of weeks and y is the total amount of money in the account.
Savings Account EquationsThe equation for the savings account can be determined by taking the initial amount of money and adding the weekly deposit over a certain number of weeks. The initial amount of money in your savings account is $50, and you plan to deposit $10 each week, so each week your balance will increase by $10.
Starting from the initial balance, after the first week, the balance will be $50 + $10 = $60. After the second week, the balance will be $60 + $10 = $70, and so on. We can represent this pattern using an equation:
y = 50 + 10x
where y is the balance after x number of weeks.
Similarly, for your friend's savings account, the initial balance is $25 and the weekly deposit is $10. So, each week the balance will increase by $10. Using the same pattern, the equation for your friend's savings account can be represented as:
y = 25 + 10x

"A music streaming service charges a flat monthly fee plus a per-song charge for each song downloaded. It cost $11 to download 2 songs during the month and $14 to download 8 songs during the month."
The equation in the form y = mx b for this function is:
y = (1/2)x + 10
To write an equation in the form y = mx + b for this function, we can use two sets of data points, (x, y), to find the slope (m) and the y-intercept (b) of the line.
Let x be the number of songs downloaded and y be the cost in dollars.
First data point: (2, 11)Second data point: (8, 14)We can use the slope formula to find m:
m = (y2 - y1) / (x2 - x1) = (14 - 11) / (8 - 2) = 3 / 6 = 1/2Next, we can use one of the data points and the slope to find b:
b = y - mx = 11 - (1/2) * 2 = 11 - 1 = 10Therefore, the equation of the line is: y = (1/2)x + 10
This equation represents the cost y in dollars of downloading x number of songs, given the flat monthly fee and per song charge.

The following are some of the circle's crucial characteristics:
If the circles have equal radii, they are said to be congruent.The longest chord in a circle is its diameter.In the center of a circle, equal chords subtend equal angles.The chord is divided in half by the radius drawn perpendicular to the chord.Circles with various radii are comparable.A circle can encircle a kite, triangle, square, trapezium, rectangle, and more.You may encircle a square, triangle, or kite with a circle.Equal in length are the chords that are equally spaced from the center.The longest chord's (diameter) distance from the circle's center is equal to zero.As the chord length rises, the perpendicular distance from the circle's center decreases.The tangents are parallel to one another if they are drawn at the diameter's end.The radii connecting the ends of a chord to the center of a circle create an isosceles triangle.The radius of the circle is 3 miles

A utility cooperative is a specific kind of cooperative that is responsible for providing its members with a public utility, such as power, water, or telecommunications. Profits are either distributed to members as "patronage" or "capital credits," which are dividends paid on a member's investment in the cooperative, or they are reinvested for infrastructure.
Every consumer is a shareholder and a member of the company. This means that, in contrast to investor-owned utilities where the amount of individual authority is determined by the number of shares held, all members have the same level of personal authority. Many utility cooperatives operate their business in accordance with a set of ideals based on the Rochdale Principles, just like cooperatives active in other industries.

If 29 student tickets were sold, then all possible values for the number of adult tickets that the drama club must sell in order to meet the show's expenses are 54 and 55 .
the price for each student ticket is $4.50 and adult is $8 ;
The number of people auditorium can hold is = no more than 84 people ;
the number of children tickets sold is = 29 tickets ;
Let "x" be number of adult tickets sold.
The total revenue from ticket sales = $4.50×29 + $8×(x)
⇒ $130.5 + $8x.
The total revenue must be at least $560,
So , $130.5 + $8x ≥ $560.
Subtracting $130.5 from both sides, we get $8x ≥ $429.5 ;
Dividing both sides by 8, we get x ≥ 53.69 ;
Since the number of adult tickets sold must be an integer, the minimum number of adult tickets that must be sold is 54.
The maximum number of people allowed in the auditorium is 84, so the maximum number of adult tickets that can be sold is 84 - 29 = 55.
Therefore, the possible values for the number of adult tickets that must be sold are 54, 55.

Step 1 Subtract 3.6 from both sides of the inequality.
Negative 5.6 greater-than-or-equal-to x + 3.6. Negative 5.6 minus 3.6 greater-than-or-equal-to x + 3.6 minus 3.6. Negative 9.2 greater-than-or-equal-to x.
Step 2 Interpret the results.
x greater-than-or-equal-to negative 9.2
x is greater than or equal to –9.2.
Step 3 Draw a number line.

A weather station on the top of a mountain reports that the temperature is currently
0'C and has been falling at a constant rate of 3°C per hour. If it continues to fall
this rate, find each indicated temperature. Explain or show your reasoning.
The needed temperature continues to decline at this pace in 2 hours -6°C, 5 hours -15°C, and half an hour -1.5°C.
How to solve this?A weather station on a mountaintop says that the temperature is now 0°C and has been dropping at a consistent pace of 3°C every hour.
We must discover,
What will the temperature be in 2 hours, 5 hours, and half an hour if it continues to plummet at current rate?
In response to the question,
A weather station on a mountaintop says that the temperature is now 0°C and has been dropping at a consistent pace of 3°C every hour.
The temperature drops by 3°C in one hour = 0 – 3 = -3°C
The temperature drops in two hours = (2)(-3°C) = -6°C
Temperature drop in 5 hours = (5)(-3°C) = -15°C
In half an hour, the temperature drops = (0.5)(-3°C) = -1.5°C.
As a result, the needed temperature continues to decline at this pace in 2 hours -6°C, 5 hours -15°C, and half an hour -1.5°C.

The required temperature will drop further at this rate in 2 hours at -6 °C, 5 hours at -15 °C, and 30 minutes at -1.5 °C.
What is the weather station on the top of a mountain?A weather station on a mountaintop says that the temperature is now 0 °C and has been dropping at a consistent pace of 3 °C every hour.
A weather station is a place equipped with tools for measuring atmospheric conditions, gathering data for weather forecasts, and researching the weather and environment.
The temperature drops by 3 °C in one hour = 0 – 3 = -3 °C. The temperature drops in two hours = (2)(-3 °C) = -6 °C
Temperature drop in 5 hours = (5)(-3 °C) = -15 °C
In half an hour, the temperature drops = (0.5)(-3 °C) = -1.5 °C.
Therefore, the needed temperature continues to decline at this pace in 2 hours -6 °C, 5 hours -15 °C, and half an hour -1.5 °C.

From 60 cm to 90cm.
% i need help
Answer:
90 is 150% of 60
OR
90 is 50% greater than 60
Step-by-step explanation:
To find the percentage increase between two values, the first step is to find the difference between the final and initial value.
Final value: 90cm
Initial value: 60cm
Difference = 90 - 60 = 30cm
Next, you need to divide the difference between the two values by the initial value.
30 / 60 = 0.5
Lastly, you need to take the value previously found and multiply it by 100 to convert it from a decimal to a percentage.
0.5 * 100 = 50%
This value will be your percentage increase.
If you want to know what percentage the final value is of the initial value, you can take the percentage you have and add 100% to it.
50% + 100% = 150%

Have a GREAT day!!!
Answer: 150%
Step-by-step explanation:
First, ask yourself what the difference between the two is: 90-60=30.
Secondly, 30 is 1/2 of 60. 1/2=50%.
You also need to add the hundred percent because we are adding 60 and 60 is 100% of 60. It increases by 50 and then 100. so 150%.
50% + 100% = 150%
