Ok so firstly, you need to remember that when a radius is touching a tangent, the angle is always equal to 90°. So x + 57° = 90°. That means your angle is 33°. You have drawn a right angle which is correct so the left triangle's angle is 90° - 33° = 57°. Now because both sides of the triangle is radius, that means c and 57° are equal. That means c = 57°.

Answer:

c = 57 degrees.

Step-by-step explanation:

This is the Alternate Segment theorem:

The angle between a chord of a circle and a tangent to the circle = the angle subtended by the chord in the alternate segment.

So c = 57 degrees.

Answer:

B.

Step-by-step explanation:

Since there in one congruent angle inbetween two congruent sides, you would use SAS to prove these triangles are congruent. this is because side, angle, side=SAS. answer D also uses SAS but puts the vertices in the wrong order so it is incorrect.

hopw this helps :)

Answer:

C

Step-by-step explanation:

First, let us clarify what (11, 0) represent

(x, y) ---> (11, 0)

The values are as followed:

x = 11

y = 0

If the problem states that x is the number of days after the promotion started, then it will be 11 days.

When we assert that it has been 11 days, we rule answers A and D.

If the problem states that y is the number of free coffee samples that remain after 11 days (because x is included in this statement), then it will be 0 samples.

Therefore, the answer will be C. After 11 days of the promotion, there will be 0 samples that are left.

Answer:

a+k ≤ 35

8a+4k ≤ 190

Some possible combinations are 10 adults and 20 kids

5 adults and 29 kids

Step-by-step explanation:

Let k= number of kids

a = number of adults

a+k ≤ 35  since you can have at most 35

8a + 4k ≤ 190 since the most you can spend is 190

Some possible combinations are 10 adults and 20 kids

(10+30 < 35 and 8*10+4*20 = 80+80 =160< 190)

Another possible combination

5 adults and 29 kids

(5+29 < 35  and 5*10 + 4*29 =50+116=166)

The kitchen is 30 meters long.

Because 16+16+30+30 = 92

It's more so trial and error if anything

Answer:

The price of a child ticket in dollars $8.00

Step-by-step explanation:

The probability that the mean run time for the 40 runners is between 141 and 143 is 0.1059.

To calculate the probability, we need to assume that the run times for the runners are normally distributed. Let's also assume that the population standard deviation is known to be 5 minutes.

The distribution of the sample mean can be approximated by a normal distribution, with the mean of the sample mean being equal to the population mean, and the standard deviation of the sample mean being equal to the population standard deviation divided by the square root of the sample size (i.e., 5 / sqrt(40)).

Now we can calculate the z-scores for the lower and upper bounds of the desired interval. The z-score formula is given by z = (x - μ) / (σ / sqrt(n)), where x is the value we want to find the probability for, μ is the population mean, σ is the population standard deviation, and n is the sample size.

For the lower bound:

z_lower = (141 - 140) / (5 / sqrt(40)) ≈ 0.8944

For the upper bound:

z_upper = (143 - 140) / (5 / sqrt(40)) ≈ 1.7889

Using a standard normal distribution table or a calculator, we can find the area under the curve between these two z-scores. The probability is equal to the area under the curve between the z-scores.

P(0.8944 < z < 1.7889) ≈ 0.1059

The probability that the mean run time for the 40 runners is between 141 and 143 minutes is approximately 0.1059, or 10.59%. This implies that there is a relatively high likelihood that the sample mean falls within this range.

Hey there! :)

Answer:

C. BC = 39 units.

Step-by-step explanation:

Use the Pythagorean theorem to solve for BC. Let BC = c, AB = a, and AC = b.

c² = a² + b²

c² = 15² + 36²

Square and simplify:

c² = 225 + 1296

c² = 1521

c = √1521

c = 39 units.

Therefore:

BC = 39 units.

Answer:

C. 39

Step-by-step explanation:

Use Pythagorean Theorem to find the missing length

15² + 36² = C²      Simplify

225 + 1296 = C²   Add

1521 = C²              Take the square root of both sides

39 = C

The six-foot long ladder is 3√5 feet high up the wall having 3 feet distance from bottom of the ladder.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. In this case, the ladder is the hypotenuse, and the wall and the ground make up the other two sides.

The ladder is 6 feet long, and the bottom of the ladder is 3 feet away from the wall, so the triangle is a 3-4-5 right triangle, which means the wall is 3 feet high.

So, if we square the length of the ladder (6^2 = 36)

The length of the base (3^2 = 9),

and add them together, then take the square root of that, we get the height of the wall.

sqrt(36+9) = sqrt(45) = 3*sqrt(5)

so the ladder is 3√5 feet high up the wall.

To prove that when a sphere is moved about its center, it is always possible to find a diameter of the sphere whose direction in the displaced position is the same as in the initial position using orthogonal properties, follow these steps:

1. Consider a sphere with center O and any diameter AB.
2. When the sphere is moved about its center, the center O remains fixed.
3. Rotate the sphere such that diameter AB is now in a new position A'B'.
4. Since the sphere has been rotated about its center, the orthogonal properties are preserved. This means that the planes that are perpendicular to the diameter at the center O remain unchanged.
5. The orthogonal planes to diameter AB intersect at the center O and form a fixed line in space.
6. Now, rotate the sphere again, such that diameter A'B' returns to its initial position as AB. This rotation is possible because the orthogonal planes and their intersection (the fixed line) are preserved.
7. Since diameter A'B' has returned to the initial position of AB, it proves that it is always possible to find a diameter of the sphere whose direction in the displaced position is the same as in the initial position.

Step-by-step explanation:

so if there were 50 less cheeseburgers then I would take 50 away from 450 and I would get 400. And then I divided it by 2. And so 200+50 = 250 so 250 hamburgers and 200 cheeseburgers. I hope this helps and I'm not good at explaining. :)

 A suggested variable control chart in the education field is a Student Attendance Rate Control Chart. This chart tracks the attendance metric and calculates it as the percentage of students present in a given time period. The information would be tracked regularly, and variations in attendance rates would be interpreted to identify trends and address potential issues.

The Student Attendance Rate Control Chart is a valuable tool in monitoring and managing attendance in educational institutions. The metric tracked on this chart is the attendance rate, which is calculated as the percentage of students present in a specific time period, such as daily, weekly, or monthly.
To track the attendance rate, the educational institution would collect attendance data for each class or session and calculate the percentage of students present. This data can be collected manually or through an automated attendance tracking system. The attendance rate for each time period is plotted on the control chart, allowing for visual representation and tracking over time.
Interpreting the information on the control chart involves analyzing the patterns and variations in the attendance rate. A stable attendance rate would indicate consistent student attendance, while fluctuations or downward trends could indicate potential issues that need attention. By monitoring the control chart, educational institutions can identify periods of low attendance, investigate the reasons behind it, and take appropriate actions such as implementing interventions or improving communication with students and parents to improve attendance rates. The control chart provides a visual representation of attendance patterns and enables proactive measures to be taken to address any attendance-related concerns.

Answer:

A = 7 * ( T * 0.15 )

Step-by-step explanation:

In this question, since the actual square footage of the rooms is not provided we can instead create the following formula which will help you calculate the total amount that you will spend on flooring these rooms.

A = 7 * ( T * 0.15 )

In this formula, variable A represents the total dollar amount that will be spent on flooring while T represents the total square footage of the entire home. T is multiplied by 0.15 which is the 15% of the home that makes up the living and dining rooms and then this square footage is multiplied by the cost of the flooring per square footage. Ultimately providing you with the total cost.

A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.

First, we need to solve for a common denominator.

A common denominator consists of two or more fractions that have the same denominator. This makes it easier to perform numeric equations, and to solve them.

To get the common denominator between \(\frac{18}{7}\) and \(\frac{5}{6}\), we multiply their denominators.

Now, we know the fractions would look like this:

To solve for the numerators, we can use these equations:

Now, the fractions look like this:

Adding them together:

Now, we can convert this into a mixed number.

Now that we have this, we can subtract that from 6 to get the missing value.

Therefore, the third fraction is \(2\frac{25}{42}\).

A mortgage payment typically includes three components:

a. Principal: the amount of money borrowed to purchase the home

b. Interest: the cost of borrowing the money from the lender

c. Taxes: property taxes assessed by the local government based on the value of the property

The down payment is the initial payment made by the borrower towards the purchase of the home, and is not a component of the mortgage payment. So the answer is D

A person with a Z-score of -0.42 would have a raw score of 992.4 on the SAT taken in 2018.

The standard deviation is a measure of how much the data varies from the mean. A Z-score is a standardized value that represents the number of standard deviations a raw score is from the mean.

To find the raw score given a Z-score, we can use the following formula:

raw score = mean + Z-score * standard deviation

For the mean composite score of 1068 and a standard deviation of 180, we can plug in the values for the Z-score of -0.42:

raw score = 1068 + (-0.42) * 180

raw score = 1068 - 75.6

raw score = 992.4

Note: The Z-score of -0.42 indicates that the raw score is 0.42 standard deviations below the mean.
