In circle C with the measure of minor arc BD=42°, find mBED.
Answer: mBED = 2(42°) = 84°
Step-by-step explanation:
We are asked to find the measure of the central angle ∠BED in the circle given that the measure of the minor arc BD is 42°.
We can use the formula that states that the measure of a central angle is equal to twice the measure of its intercepted arc. That is,
m∠BED = 2*mBD
We can substitute the value of mBD, which is 42°, into our equation.
m∠BED = 2*42°
m∠BED = 84°
Therefore, the measure of the central angle ∠BED is 84°.
Explain the difference between a) comparing, b) non-standard units of measurement and c) standardised units of measurement.
Answer:
a) Comparing: Comparing means evaluating the similarity or difference between two or more objects, values, or variables. It is a process of identifying and highlighting the similarities and differences among objects, values, or variables based on specific criteria.
b) Non-standard units of measurement: Non-standard units of measurement are those that are not part of the International System of Units (SI) and are often created for specific purposes or contexts. These units may be used to measure variables such as time, distance, weight, or volume, but they are not universally recognized or standardized.
c) Standardized units of measurement: Standardized units of measurement are those that are part of the International System of Units (SI) and are universally recognized and accepted. These units provide a standard framework for measuring variables such as time, distance, weight, or volume, making it possible to compare and communicate measurements accurately across different contexts and languages. Some examples of standardized units of measurement include seconds, meters, kilograms, and liters.
The figure below represents 17/36 of a full circle. Find the measure of the marked central angle.
The specified central angle is 170 degrees since the figure is 17/36 of a full circle.
A central angle is an angle with endpoints on the perimeter and a vertex in the centre of a circle. An arc is defined by the angle in the centre of a circle.
Since the figure represents 17/36 of a full circle, the central angle that it subtends is also equal to 17/36 of 360 degrees (the measure of a full circle).
We can calculate this as follows:
Central angle = (17/36) x 360 degrees
Central angle = 17 x 10 degrees
Central angle = 170 degrees
Therefore, the measure of the marked central angle is 170 degrees.

f(-2) = 0
Step-by-step explanation:
f(x) = (2x+4)/6 is a "rule" or like, directions. It says take your number, times by 2, add 4 and then divide by 6.
f(-2) just means to put -2 in place of x. Do the "rule" or follow the directions on the number -2.
f(x) = (2x+4)/6
f(-2) = (2•-2 + 4)/6
= (-4+4)/6
= 0/6
= 0
So f(-2) = 0
If Marie were to paint her living room alone, it would take 3 hours. Her sister Fran could do the job in 6 hours. How many hours would it take them working together? Express your answer as a fraction reduced to lowest terms, if needed.
The time it takes them to paint the living room together is 2 hours. Expressing this as a fraction reduced to lowest terms 2 hours is 2/1.
What is time working together?Time working together refers to the amount of time that two or more people need to work together to complete a certain task. It is often used in situations where people are working collaboratively or cooperatively to achieve a common goal.
According to question:Let's denote the time it takes Marie to paint the living room alone by M and the time it takes Fran to paint the living room alone by F.
From the problem, we know that:
M = 3 hours
F = 6 hours
To determine the time it takes them to paint the living room together, we can use the following formula:
1 / (time working together) = 1 / M + 1 / F
Substituting the values we have:
1 / (time working together) = 1 / 3 + 1 / 6
Simplifying the right-hand side of the equation:
1 / (time working together) = 2 / 6 + 1 / 6
1 / (time working together) = 3 / 6
1 / (time working together) = 1 / 2
Therefore, the time it takes them to paint the living room together is 2 hours. Expressing this as a fraction reduced to lowest terms:
2 hours = 2/1
So the answer is: 1 / (time working together) = 1 / 2, or equivalently, the time working together is 2/1.

Let a and b be real numbers, where Which of the following functions could represent the graph on the right? f(x) = x (x – a)(x – b)2 f(x) = (x – a)(x – b)2 f(x) = x(x – a)³(x – b) f(x) = x2(x – a) 2(x – b)2
Answer:
Without a graph provided, it's difficult to determine which of the given functions represents the graph on the right. However, we can analyze each function to see if it has any characteristics that match the shape of the graph.
f(x) = x(x – a)(x – b)2
This function has one x-intercept at x = 0 and a double root at x = b. If b > a, then the function will have a local maximum at x = a and a local minimum at x = b. This function may represent a graph with a single x-intercept, a double root, and a local maximum and minimum.
f(x) = (x – a)(x – b)2
This function has one x-intercept at x = a and a triple root at x = b. If b > a, then the function will have a local minimum at x = a and a local maximum at x = b. This function may represent a graph with a single x-intercept, a triple root, and a local minimum and maximum.
f(x) = x(x – a)³(x – b)
This function has one x-intercept at x = 0 and a triple root at x = a. If a < b, then the function will have a local minimum at x = b. This function may represent a graph with a single x-intercept, a triple root, and a local minimum.
f(x) = x²(x – a)²(x – b)²
This function has two x-intercepts at x = 0 and x = a and a double root at x = b. If b > a, then the function will have a local maximum at x = a and a local minimum at x = b. This function may represent a graph with two x-intercepts, a double root, and a local minimum and maximum.

If the anticipated claim outcome actually occurs, it will be feasible to get in connection with the entity once more; if not, both crucial systems will undoubtedly miss the statement.
Here,
The pressure of the gas inside the can will rise as the temperature rises. This is due to the fact that the gas particles inside the can will accelerate and acquire kinetic energy, causing them to collide with the can's walls more frequently and more violently.
The pressure rises as a result of these collisions' greater power per unit area.
The Ideal Gas Law, which says that PV = nRT, where P is tension, V is volume, n is the number of moles of gas,
R is the optimal gas constant, and T is temperature in Kelvin, describes this relationship between pressure and temperature.

What is geometric mean?The Geometric Mean (GM) in mathematics is the average value or mean that, by calculating the product of the values of the collection of numbers, denotes the central tendency of the numbers. In essence, we multiply the numbers collectively and calculate their nth root, where n is the total amount of data values.
In other terms, the geometric mean is the product of n numbers divided by the nth root. As a result of the fact that in mathematical mean, the data values are added before being divided by the total number of values. However, when calculating the geometric mean, we add the provided data values before taking the root of the total number of data values using the radical index.
What is Square root?A number's square root is a value that, when multiplied by itself, yields the initial number. The opposite way to square an integer is to find its square root. Squares and square roots are therefore connected ideas.

cost per pound of the cinnamon tea and of the spice tea.
cinnamon
spice
Answer:
Step-by-step explanation:
Let x be the cost per pound of the cinnamon tea and y be the cost per pound of the spice tea.
From the first mixture, we have:
12x + 3y = 39
From the second mixture, we have:
16x + 6y = 58
We can solve this system of equations by elimination. Multiplying the first equation by 2 and subtracting it from the second equation gives:
16x + 6y = 58
(24x + 6y = 78)
-8x = -20
Dividing both sides by -8 gives:
x = 2.5
Substituting this value of x into the first equation, we get:
12(2.5) + 3y = 39
Simplifying, we get:
30 + 3y = 39
Subtracting 30 from both sides gives:
3y = 9
Dividing both sides by 3 gives:
y = 3
Therefore, the cost per pound of the cinnamon tea is $2.50 and the cost per pound of the spice tea is $3.
If I get paid $12.50 an hour and I worked a total of 15 hours and 35 minutes how much did I make?
Answer: $194.79
Step-by-step explanation:
It is easiest to approach this question in two parts.
First part is simple - multiply the wage per hour times the number of whole number you have worked. ($12.50)(15) = $187.50
Next you need to find how much you make in 35 minutes at a wage rate of 12.50 an hour. You can set up a ratio to find this out -
($12.50) | (60 min) - (x dollars) | (35 min)
then cross multiply and divide - (12.5 * 35) / 60 = 7.291
This means you make $7.29 for 35 minutes of work.
$187.50 + $7.29 = $194.79 for 15 hours 35 minutes of work.

type of measurement enables learners to quantify the measurement of an object, but differs in amount each time.
Answer:
variable measurement
Step-by-step explanation:
The type of measurement you are referring to is called "variable measurement". In variable measurement, the quantity being measured can vary from one observation to another. This means that the measurement is not consistent or fixed, and can change each time it is taken. An example of variable measurement is measuring the weight of a person over time, as their weight can change from one day to another. Another example is measuring the temperature in a room throughout the day, as the temperature can fluctuate based on factors such as sunlight, air conditioning, and human activity.
A study found that the mean amount of time cars spent in drive-throughs of a certain fast-food restaurant was 137.5 seconds. Assuming drive-through times are normally distributed with a standard deviation of 27 seconds, complete parts below:
The probability that a randomly selected car will get through the restaurant's drive-through in less than 101 seconds is -1.3
What is normal distribution ?
Normal distribution, also known as Gaussian distribution or bell curve, is a continuous probability distribution that is commonly used in statistical analysis to model real-world phenomena. A normal distribution is characterized by its mean (μ) and standard deviation (σ), and is symmetrical around its mean. The bell-shaped curve of a normal distribution is determined by the empirical rule, also known as the 68-95-99.7 rule, which states that approximately 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations. Many natural phenomena, such as human height and weight, tend to follow a normal distribution, and this makes normal distribution a useful tool in statistical analysis and modeling.
According to the question:
(a) To find the probability that a randomly selected car will get through the restaurant's drive-through in less than 101 seconds, we need to standardize the value using the formula:
z = (x - μ) / σ
where x is the value we are interested in, μ is the mean drive-through time, σ is the standard deviation, and z is the corresponding z-score.
Plugging in the values given, we get:
z = (101 - 137.5) / 27 = -1.3
Using a standard normal distribution table or a calculator, we find that the probability of getting a z-score less than -1.35 is 0.0885. Therefore, the probability that a randomly selected car will get through the restaurant's drive-through in less than 101 seconds is:
P(X < 101) = P(Z < -1.35) = 0.0885 (rounded to four decimal places).
(b) To find the probability that a randomly selected car will spend more than 176 seconds in the restaurant's drive-through, we again need to standardize the value:
z = (176 - 137.5) / 27 = 1.42
Using a standard normal distribution table or a calculator, we find that the probability of getting a z-score greater than 1.42 is 0.0788. Therefore, the probability that a randomly selected car will spend more than 176 seconds in the restaurant's drive-through is:
P(X > 176) = P(Z > 1.42) = 0.0788 (rounded to four decimal places).
(c) To find the proportion of cars that spend between 2 and 3 minutes (120 and 180 seconds) in the restaurant's drive-through, we need to standardize the values of the lower and upper limits:
z1 = (120 - 137.5) / 27 = -0.65
z2 = (180 - 137.5) / 27 = 1.57
Using a standard normal distribution table or a calculator, we find the area between these two z-scores to be 0.6591. Therefore, the proportion of cars that spend between 2 and 3 minutes in the restaurant's drive-through is:
P(120 < X < 180) = P(-0.65 < Z < 1.57) = 0.6591 (rounded to four decimal places).
(d) To find the probability that a car spends more than 3 minutes (180 seconds) in the restaurant's drive-through, we standardize the value:
z = (180 - 137.5) / 27 = 1.57
Using a standard normal distribution table or a calculator, we find that the probability of getting a z-score greater than 1.57 is 0.0582. Since this probability is less than 0.05, it would be considered unusual for a car to spend more than 3 minutes in the restaurant's drive-through.
