Answer 1

For quadrilateral ABCD x=85 and angle B= 23°.

What is quadrilateral?

A quadrilateral is a polygon with four sides and four angles. It is a closed figure and can have different shapes and sizes, depending on the length of its sides and the angles between them.

According to given information:

(a) Supplementary equation used to solve for x:

∠A + ∠C = 180°

(b) All math used to calculate for x:

∠A + ∠C = 180°

(x - 5) + (x + 15) = 180 (substitute the given values for ∠A, ∠C)

2x - 10 = 180

2x = 170

x = 85

(c) Correct value for x:

x = 85

(d) Plugging x into expressions for angles A, C, D:

∠A = x - 5 = 2(85) - 5 = 165

∠C = x + 15 = 85 + 15 = 100

∠D = x - 13 = 85 - 13 = 72

(e) All math used to calculate the measures of angles A, C, D:

∠A + ∠B + ∠C + ∠D = 360° (sum of angles in a quadrilateral)

165 + ∠B + 100 + 72 = 360

∠B = 23

Therefore, the measures of the angles are:

∠A = 165°

∠B = 23°

∠C = 100°

∠D = 72°

(f) All math used to calculate the measure of angle B:

∠B = 360 - ∠A - ∠C - ∠D

∠B = 360 - 165 - 100 - 72

∠B = 23°

An aircraft (at Z) is spotted by two observers (at X and Y) who are L = 1850 feet apart. As the airplane
passes over the line joining them, each observer takes a sighting of the angle of elevation to the plane,
as indicated in the figure. If A=25°, and B=25°, how high is the airplane?

Answers

Answer: We can use trigonometry to solve this problem. Let's call the height of the airplane H, and let's call the distance from observer X to the airplane D. Then the distance from observer Y to the airplane is L - D.

From the point of view of observer X, we can write:

tan(A) = H / D

tan(25°) = H / D

From the point of view of observer Y, we can write:

tan(B) = H / (L - D)

tan(25°) = H / (L - D)

We now have two equations with two unknowns (H and D). We can solve for one of the unknowns in terms of the other, and then substitute that expression into the other equation to eliminate one of the unknowns.

Let's solve the first equation for D:

D = H / tan(25°)

Substituting this expression for D into the second equation, we get:

tan(25°) = H / (L - H / tan(25°))

Multiplying both sides by (L - H / tan(25°)), we get:

tan(25°) (L - H / tan(25°)) = H

Expanding the left-hand side, we get:

tan(25°) L - H = H tan^2(25°)

Adding H to both sides, we get:

tan(25°) L = H (1 + tan^2(25°))

Dividing both sides by (1 + tan^2(25°)), we get:

H = (tan(25°) L) / (1 + tan^2(25°))

Now we can substitute this expression for H into the equation D = H / tan(25°) to get:

D = ((tan(25°) L) / (1 + tan^2(25°))) / tan(25°)

Simplifying, we get:

D = L / (1 + tan^2(25°))

Now that we know the distance D, we can use the equation tan(A) = H / D to find H:

tan(25°) = H / D

H = D tan(25°)

Substituting D = L / (1 + tan^2(25°)), we get:

H = (L / (1 + tan^2(25°))) tan(25°)

Plugging in the given values L = 1850 feet and A = B = 25°, we get:

H = (1850 / (1 + tan^2(25°))) tan(25°)

H ≈ 697.3 feet

Therefore, the airplane is about 697.3 feet high.

Based on this data, what is a reasonable estimate of the probability that Patsy sells fewer than 5 feathers next festival?

Answers

A reasonable estimate of the probability that Patsy sells fewer than 2 feathers at the next festival is about 0.2485.

How to estimate the probability of given data?

To estimate the probability that Patsy sells fewer than a certain number of feathers at the next festival, we need to use the given data to calculate the mean and standard deviation of the number of feathers she has sold in the past festivals.

The mean, denoted by μ, is calculated by adding up all the number of feathers sold and dividing by the total number of festivals. So,

μ = (3 + 6 + 1 + 4 + 2 + 3 + 7 + 2) / 8 = 3.375

The standard deviation, denoted by σ, is a measure of how spread out the data is. It is calculated by first finding the variance, which is the average of the squared differences between each data point and the mean, and then taking the square root of the variance. So,

Variance = ((3-3.375)² + (6-3.375)²+ (1-3.375)² + (4-3.375)² + (2-3.375)² + (3-3.375)² + (7-3.375)² + (2-3.375)²) / 8 = 4.0898

σ = √(4.0898) = 2.022

Now, to estimate the probability that Patsy sells fewer than a certain number of feathers at the next festival, we need to standardize the value by subtracting the mean and dividing by the standard deviation. So, let X be the number of feathers sold at the next festival, then,

Z = (X - μ) / σ

Let's say we want to estimate the probability that Patsy sells fewer than 2 feathers at the next festival. Then,

Z = (2 - 3.375) / 2.022 = -0.679

We can use a standard normal distribution table or calculator to find the probability that a standard normal random variable is less than -0.679, which is approximately 0.2485.

Therefore, a reasonable estimate of the probability that Patsy sells fewer than 2 feathers at the next festival is about 0.2485.

What is the polynomial equation?

A polynomial equation is an equation in which the variable is raised to a power, and the coefficients are constants. A polynomial equation can have one or more terms, and the degree of the polynomial is determined by the highest power of the variable in the equation.

When f(x) is divided by 3x + 1, the quotient is 3x² - 4x - 1 and the remainder is -10. We can use polynomial long division to write f(x) in the form:

f(x) = (3x² - 4x - 1)(3x + 1) - 10

Multiplying out the right side gives:

f(x) = 9x³ - 7x² - 13x - 11

Triangle PQR has vertex coordinates at P(4, 0), Q(4, 3), R(5, 1). If the triangle is translated so that Q′(4, −5), determine the translation direction and number of units.

8 units down
8 units up
8 units to the right
8 units to the left

Answers

Answer:

To determine the translation direction and number of units, we need to find the vector that connects Q to Q', and then determine the magnitude and direction of that vector.

The vector that connects Q to Q' can be found by subtracting the coordinates of Q from the coordinates of Q':

Q' - Q = (4, -5) - (4, 3) = (0, -8)

This vector indicates a translation 8 units downwards, in the negative y direction. Therefore, the translation direction is downwards and the number of units is 8.

So the correct answer is: 8 units down.

Final answer:

Triangle PQR was translated 8 units down.

Explanation:

In mathematics, particularly in the field of geometry, a translation refers to moving each point in a shape or a figure to a different position by sliding it to a certain direction for a fixed number of spaces. Each point is moved the same distance and in the same direction.

In the case of your Triangle PQR, the Q point moves from (4, 3) to the new coordinate Q'(4, -5). The x-coordinate in both points remains at 4. Hence, there's no left or right movement. But the y-coordinate changes from 3 to -5. This indicates a downward movement. The distance between 3 and -5 on the number line is 8 units. Therefore, the triangle was translated 8 units down.

purchase?
A. 3 weeks

Answers

The minimum number of weeks Kade should wait before making his purchase is 5 weeks.

Given that, Kade has $40 as his saving, and he wants to buy a video game console that costs $250 plus 8.25% sales tax.

He saves $50 each week to buy the same, we need to find the number weeks in which he can buy the game,

Total cost of the game = 250 + 250 × 8.25%

= 250 + 250 × 0.0825

= 250 + 20.625

= 270.625

Hence, he needs to save = $270.625 - $40 = $230.625

Let the number of weeks be x,

Answer: Assuming that we can make each cut with perfect precision and that the thickness of each cut is negligible, we can estimate the number of cuts needed to reduce the strip of paper to approximately 10 nanometers in length as follows:

Convert 10 centimeters to nanometers:

10 cm = 10,000,000,000 nanometers

Divide the length of the strip by the desired final length:

10,000,000,000 / 10 = 1,000,000,000

Therefore, approximately 1 billion cuts would be needed to reduce the strip of paper to approximately 10 nanometers in length.

In the tally chart, each vertical line represents one data point. So, for example, the group 1-5 has 5 data points, which we represent with five vertical lines (|||||).

To work out the frequency of each group, we simply count the number of tally marks in each group. The frequency is the number of data points that fall within each group. Based on the above tally chart, we have:

1-5: 5

a tank contains 60 kg of salt and 2000l of water. a solution of a concentration 0.015 kg of salt per liter enters a tank at the rate 9l/min. the solution is mixed and drains from the tank at the same rate. (a) what is the concentration of our solution in the tank initially? (b) find the amount of salt in the tank after 3.5 hours. (c) find the concentration of salt in the solution in the tank as time approaches infinity.

Answers

(a) The concentration of the solution in the tank will be changing over time.

(b) The amount of salt in the tank after 3.5 hours is 63.292 kg.

(c) When the inflow and outflow rates are equal, the amount of salt in the tank will remain constant.

(a) To find the concentration of the solution in the tank initially, we can use the formula:

concentration = mass of salt / volume of solution

The mass of salt in the tank initially is 60 kg, and the volume of solution is 2000 liters.

Therefore, the initial concentration is:

concentration = 60 kg / 2000 L

concentration = 0.03 kg/L

However, we know that a solution with a concentration of 0.015 kg/L is entering the tank at a rate of 9 L/min.

Therefore, the concentration of the solution in the tank will be changing over time.

(b) To find the amount of salt in the tank after 3.5 hours, we can use the formula:

amount of salt = initial amount of salt + (concentration of incoming solution - concentration of solution in tank) x rate x time

The initial amount of salt is 60 kg, and the concentration of the incoming solution is 0.015 kg/L.

We need to find the concentration of the solution in the tank after 3.5 hours.

The rate of flow is 9 L/min, so the total volume of solution that has entered the tank after 3.5 hours is:

volume of solution = rate x time

volume of solution = 9 L/min x 210 min

volume of solution = 1890 L

The total volume of solution in the tank after 3.5 hours is:

total volume = initial volume + volume of incoming solution - volume of drained solution

total volume = 2000 L + 9 L/min x 210 min - 9 L/min x 210 min

total volume = 2000 L

Therefore, the concentration of salt in the tank after 3.5 hours is:

amount of salt = 60 kg + (0.015 kg/L - concentration of solution in tank) x 9 L/min x 210 min

amount of salt - 60 kg = (0.015 kg/L - concentration of solution in tank) x 1890 L

concentration of solution in tank = 0.015 kg/L - (amount of salt - 60 kg) / 1890 L

Now we can substitute the concentration of the solution in the tank into the formula and solve for the amount of salt:

amount of salt = 60 kg + (0.015 kg/L - (0.015 kg/L - (amount of salt - 60 kg) / 1890 L)) x 9 L/min x 210 min

amount of salt = 63.292 kg

Therefore, the amount of salt in the tank after 3.5 hours is 63.292 kg.

(c) To find the concentration of salt in the solution in the tank as time approaches infinity, we need to find the concentration that the solution will reach when the inflow and outflow rates of solution are equal.

At this point, the amount of salt in the tank will remain constant.

Let's denote the concentration of salt in the solution in the tank as c.

We know that the volume of solution in the tank remains constant at 2000 L, and that the inflow and outflow rates are both 9 L/min. Therefore, the amount of salt that enters the tank per minute is 0.015 kg/L x 9 L/min = 0.135 kg/min, and the amount of salt that leaves the tank per minute is c x 9 L/min.

When the inflow and outflow rates are equal, the amount of salt in the tank will remain constant.

Therefore, we can set the rate of inflow equal to the rate of outflow and solve for c:

0.015 kg/L x 9.

Bus 47, with a median of 16
Bus 14, with a median of 14
Bus 47, with a mean of 16
Bus 14, with a mean of 14

Answers

Answer:

(A) Bus 47, with a median of 16.

Step-by-step explanation:

To determine which bus typically has the faster travel time, we need to compare the measures of center for each data set. Since the data sets are small and discrete, we can use either the median or the mean as a measure of center.

For Bus 47, the median is the middle value, which is 16.For Bus 14, the median is also the middle value, which is 14.

Comparing the medians, we can see that Bus 47 has a higher median, which suggests that it typically has a faster travel time than Bus 14.

Therefore, the answer is (A) Bus 47, with a median of 16.

the product of three distinct positive integers is 144. if the sum of the three integers is 26, what is the sum of their squares?

Answers

We can then check the sum of each set of three integers and see which one adds up to 26. We find that the set 2, 8, 16 has a sum of 26, so these are the three distinct integers that multiply to 144.Therefore, the sum of the squares of the three integers is 324.

To solve this problem, we can start by listing all the factors of 144 and looking for three distinct integers that multiply to 144. The factors of 144 are 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, and 144. We can eliminate any factor that is not a positive integer or is repeated, leaving us with the following possibilities:
- 1, 2, 72
- 1, 3, 48
- 1, 4, 36
- 1, 6, 24
- 2, 3, 24
- 2, 4, 18
- 2, 8, 9
- 3, 4, 12
- 3, 6, 8


To find the sum of their squares, we simply square each integer and add them together:

of the 64 caps is selected at random, what is the probability it will not be green?
25%
75%

50%

Answers

The answer is option (b) 75%.

What is Probability?

Probability is a measure of the likelihood that a particular event will occur. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. The probability of an event can be determined by dividing the number of ways the event can occur by the total number of possible outcomes.

The probability of selecting a non-green cap is the number of non-green caps divided by the total number of caps:

P(non-green) = 48/64 = 3/4 = 0.75

Therefore, the probability that a randomly selected cap will not be green is 0.75 or 75%.

So the answer is option (b) 75%.
