The terminal point is (0.866025, 0.5) and the tangent of θ is 0.55735 for θ = π/6 radians.

When the angle is given as 0 radians (0 = π/6 radians), the terminal point of the angle is on the positive x-axis.

The terminal point represents the point in the coordinate system where a given angle and distance (or magnitude) from the origin are located.

For any angle a, the coordinates of the terminal point are given by:

x = cos(a)

y = sin(a).

In this case, the angle is a = π/6

Then the coordinates of the terminal point are:

x = cos(π/6) = 0.5

  = 0.866025

y = sin(π/6)

  = 0.5

So the terminal point is (0.866025, 0.5)

The quotient of the y-component and the x-component is the tangent of that angle:

tan(π/6) = 0.5/ 0.866025

            = 0.57735

Therefore, the terminal is (0.866025, 0.5) and the tangent is 0.55735.

The probability that someone went to either homecoming or prom is 1, or 100%.

To find the probability that someone went to either homecoming or prom, we need to add the number of students who went to each dance and then subtract the number of students who went to both dances (as they would have been counted twice in the first step).

So, the total number of students who went to either homecoming or prom is:

250 + 300 - 200 = 350

Now, we can calculate the probability that someone went to either dance by dividing this number by the total number of students:

P(homecoming or prom) = 350 / (250 + 300 - 200) = 350 / 300 = 1.17

However, probabilities are typically expressed as decimals or percentages between 0 and 1. Since it's impossible for someone to have a probability greater than 1, we can conclude that there is an error in our calculation. This is likely because we made a mistake when adding or subtracting the number of students.

To correct this, we need to double-check our work and make sure we have the correct numbers. Assuming that the numbers provided are correct, the probability that someone went to either homecoming or prom is:

P(homecoming or prom) = 350 / (250 + 300 - 200) = 350 / 350 = 1

The cyclist needs to ride approximately 23.21 km in the direction of 23.13° W of North to get back to the starting point.

We can use trigonometry to find the x and y components.

x3 = 12 * cos(15°) ≈ 11.59 km (east)

y3 = -12 * sin(15°) ≈ -3.10 km (south, hence the negative sign)

Leg #4: 14 km [South]

x4 = 0 km (no east/west movement)

y4 = -14 km (south, hence the negative sign)

Now, let's find the total x and y displacements:

x_total = x1 + x2 + x3 + x4 ≈ 0 + 10 + 11.59 + 0 ≈ 21.59 km

y_total = y1 + y2 + y3 + y4 ≈ 8 + 0 - 3.10 - 14 ≈ -9.10 km

The probability of selecting an Ace, not replacing it, and then selecting a King is 4/663 or approximately 0.006 or 0.6%.

The probability of selecting an Ace, not replacing it, and then selecting a King can be calculated using the rules of conditional probability.

First, we need to determine the probability of selecting an Ace from a standard deck of 52 cards. There are four Aces in the deck, so the probability of selecting an Ace is 4/52, which can be simplified to 1/13.

Next, we need to consider the fact that the Ace is not replaced before selecting the King. This means that the deck now contains 51 cards, with only three remaining Aces. Therefore, the probability of selecting a King after selecting an Ace without replacement is 4/51.

To determine the overall probability of selecting an Ace and then a King, we multiply the probability of selecting an Ace (1/13) by the probability of selecting a King after selecting an Ace without replacement (4/51).

The calculation is as follows:

(1/13) x (4/51) = 4/663

The weight of the heaviest 20% of fruits can be estimated using the z-score corresponding to the 80th percentile, which is 0.84.

The weight can be calculated by adding the z-score multiplied by the standard deviation to the mean weight. Therefore, the weight of the heaviest 20% of fruits is approximately 405 grams.

To calculate this, we first need to find the z-score for the 80th percentile, which is 0.84. Then, we can use the formula z = (x - mu) / sigma, where x is the weight we want to find, mu is the mean weight, and sigma is the standard deviation.

Rearranging this formula to solve for x, we get x = z * sigma + mu. Plugging in the values we have, we get x = 0.84 * 20 + 374 = 405.2 grams. Rounding this to the nearest gram, we get the answer of 405 grams.

The surface area of Dante's tent is approximately 180 square feet.

To find the surface area of Dante's tent, we need to find the area of each of its faces and then add them up. Since the tent is in the shape of a triangular prism, it has three rectangular faces and two triangular faces.

First, let's find the area of each rectangular face. We know that the tent is 8 feet long and 4.3 feet tall. To find the width of each face, we need to use the Pythagorean theorem since the base of the tent is equilateral. So, we can use a triangle with sides of 5 feet (the base of the tent) and 4.3 feet (the height of the triangular face) to find the width of each rectangular face.

a^2 + b^2 = c^2
5^2 + 4.3^2 = c^2
25 + 18.49 = c^2
43.49 = c^2
c = √43.49
c ≈ 6.6 feet

Now that we know the width of each rectangular face, we can find the area of each face:

Area of rectangular face = length x width
Area of rectangular face = 8 x 6.6
Area of rectangular face ≈ 52.8 square feet

Next, let's find the area of each triangular face. Since the base of the tent is equilateral, each triangular face has a base of 5 feet and a height of 4.3 feet. The area of each triangular face is:

Area of triangular face = (base x height) / 2
Area of triangular face = (5 x 4.3) / 2
Area of triangular face ≈ 10.8 square feet

Now we can add up the areas of all five faces to find the total surface area of the tent:

Surface area of tent = 3 x area of rectangular face + 2 x area of triangular face
Surface area of tent = 3 x 52.8 + 2 x 10.8
Surface area of tent = 158.4 + 21.6
Surface area of tent ≈ 180 square feet

Therefore, the surface area of Dante's tent is approximately 180 square feet.

The measure of angle ABC is 30 degrees.

To find the measure of angle ABC, we need to use the fact that the sum of angles in a triangle is always 180 degrees. Since we know that angle ABD is a right angle (90 degrees) and angle CBD is 60 degrees, we can find the measure of angle ABC as follows:

angle ABD + angle CBD + angle ABC = 180 degrees

Substituting the given values, we get:

90 degrees + 60 degrees + angle ABC = 180 degrees

Simplifying, we get:

150 degrees + angle ABC = 180 degrees

Now we can solve for angle ABC by subtracting 150 degrees from both sides:

angle ABC = 180 degrees - 150 degrees

angle ABC = 30 degrees

Therefore, angle ABC measures 30 degrees.

what is  common factor ?

A common factor is a number that divides evenly into two or more other numbers. For example, the common factors of 12 and 18 are 1, 2, 3, and 6, because all of these numbers divide evenly into both 12 and 18.

In the given question,

From the given table, we can see that:

The first row reads 40, 45, 50 (which are multiples of 5).

The second row has an unknown number (let's call it x), 54, and 60.

The third row reads 56, an unknown number (let's call it y), 70 (which are also multiples of 7).

To find the missing numbers, we can use the fact that multiplication is commutative, meaning that the order of the factors does not matter. Therefore, we can fill in the missing numbers by looking for factors that are common to both the row and column headers.

Starting with the second row, we can see that the common factor between x and 54 is 9, since 9 x 6 = 54 and 9 x x = ?. So, the missing number in the second row is 9 x 10 = 90.

Moving on to the first column, we can see that the common factor between 40 and 56 is 8, since 8 x 5 = 40 and 8 x 7 = 56. So, the missing number in the second row, first column is 8 x 9 = 72.

Finally, we can find the missing number in the first row, second column by finding the common factor between 45 and 60, which is 15, since 15 x 3 = 45 and 15 x 4 = 60. So, the missing number in the first row, second column is 15 x 5 = 75.
