A ship sailed from Port X to Port Y. It traveled 20 kilometers due north and then 25 kilometers due west. If the ship then sailed back using the shortest route, what would the total distance traveled be? Round to the nearest kilometer.

Answers

Answer 1

The total distance traveled by the ship, including the trip from Port X to Port Y and the return trip, is approximately 42 kilometers.

What is Kilometer ?

Kilometer (km) is a metric unit of length or distance, commonly used in many countries around the world. It is equal to 1000 meters, or approximately 0.62 miles.

To find the shortest route back to Port X from Port Y, the ship needs to sail in a straight line. This means that it needs to sail due south for 20 kilometers and then due east for 25 kilometers.

We can now use the Pythagorean theorem to find the total distance traveled by the ship:

total distance = √(400+ 625 + 400+ 625)

total distance = √(1200 + 625)

total distance = √1825

total distance ≈ 42.73 kilometers (rounded to the nearest kilometer)

Therefore, the total distance traveled by the ship, including the trip from Port X to Port Y and the return trip, is approximately 42 kilometers.

State your answer as a fraction

Answers

The probability of rolling a sum of 6 when two standard six-sided dice are rolled is 5/36, or approximately 0.139.

What is probability?

The probability of an event occurring is defined by probability. There are many instances in real life where we may need to make predictions about how something will turn out.

There are 36 possible outcomes when two standard six-sided dice are rolled. Each die has 6 possible outcomes, so the total number of outcomes is 6 x 6 = 36.

To find the probability of rolling a sum of 6, we need to count the number of ways we can get a sum of 6. There are five possible ways to get a sum of 6:

- Roll a 1 on the first die and a 5 on the second die

- Roll a 2 on the first die and a 4 on the second die

- Roll a 3 on the first die and a 3 on the second die

- Roll a 4 on the first die and a 2 on the second die

- Roll a 5 on the first die and a 1 on the second die

So, the probability of rolling a sum of 6 is 5/36.

Can you guess how many quarters TJ and Demi have in their pockets? And one Demi has nine more quarters than tj. And two if you double the number of quarters TJ has and triple the number of quarters then he has you would get 112 quarters in total. How many quarters does TJ have?​

Answers

Answer: TJ has 17 quarters and Demi has 26 quarters.

Step-by-step explanation:

Let t be the number of quarters TJ has and d be the number of quarters Demi has.

First, we will write an equation based on the first detail given:

       d = t + 9

Next, we will write an equation based on the second detail given:

       2t + 3d = 112

Now, we will substitute the first equation into the second and solve for t.

       2t + 3d = 112

       2t + 3(t + 9) = 112

       2t + 3t + 27 = 112

       5t + 27 = 112

       5t = 85

       t = 17 quarters

Lastly, we know that Demi has 9 more quarters than TJ. We will add 9.

       17 quarters + 9 quarters = 26 quarters

Answer:

TJ has 17 quarters.

Step-by-step explanation:

Let d and t equal the numbers of quarters Demi and TJ have, respectively.

"Demi has nine more quarters than TJ."

d = t + 9

"if you double the number of quarters TJ has and triple the number of quarters then he has you would get 112 quarters in total"

I think that "then he" above really should read "Demi."

2t + 3d = 112

d = t + 9

2t + 3d = 112

2t + 3(t + 9) = 112

2t + 3t + 27 = 112

5t = 85

t = 17

Answers

Danielle spent $23.50 on long distance charges this past month.

To determine how much Danielle spent on long distance, we need to consider her basic cell phone rate, voice mail, and text messaging charges. Here is a step-by-step explanation:

1. Danielle's basic cell phone rate each month is $29.95.
2. She pays an additional $5.95 for voice mail.
3. She also pays $2.95 for text messaging.
4. Her total bill for the month was $62.35.

Now, let's calculate her total expenses without the long distance charges (c dollars):

$29.95 (basic cell phone rate) + $5.95 (voice mail) + $2.95 (text messaging) = $38.85

Since Danielle's total bill was $62.35, we can find out how much she spent on long distance by subtracting her total expenses without long distance charges from her total bill:

$62.35 (total bill) - $38.85 (total expenses without long distance) = $23.50

So, Danielle spent $23.50 on long distance charges this past month.

Answers

The probability of the die landing on a vowel is 1 in 5, or 20%.

In this game, the 20-sided die has the letters A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, R, S, T, and W. To calculate the probability of the die landing on a vowel, we need to identify the vowels present on the die and then determine the probability.

The vowels on this die are A, E, I, and O. There are 4 vowels out of the 20 possible outcomes, so the probability of landing on a vowel can be calculated by dividing the number of successful outcomes (vowels) by the total number of possible outcomes (20 sides).

Probability = (Number of Vowels) / (Total Sides)
Probability = 4 / 20

In triangle efg, ef=fg. if m < e = (4x+50), m < f = (2x+60), and m < g = (14x+30), find m < g

Answers

In the given  isosceles triangle, the measure of angle G is 74 degrees.

In the given problem, we are dealing with an isosceles triangle where angle G measures 74 degrees. It is mentioned that EF and FG are congruent, indicating that triangle EFG is isosceles.

Since EFG is an isosceles triangle, we can conclude that angles E and G are congruent. Therefore, we can set the measure of angle E equal to the measure of angle G and solve for x.

By setting 4x + 50 (measure of angle E) equal to 14x + 30 (measure of angle G), we have the equation 4x + 50 = 14x + 30.

Solving for x, we find that x = 2.

Now that we have the value of x, we can substitute it into each angle measure to determine their values.

The measure of angle E (mE) is given by 4x + 50, which becomes 4(2) + 50 = 58 degrees.

The measure of angle F (mF) is given by 2x + 60, which becomes 2(2) + 60 = 64 degrees.

Finally, the measure of angle G (mG) is already known to be 74 degrees.

Therefore, the measures of the angles in the isosceles triangle are: mE = 58 degrees, mF = 64 degrees, and mG = 74 degrees.

By understanding the properties of isosceles triangles and utilizing algebraic equations, we can determine the measures of the angles in the given triangle.

Answers

In ΔKLM, m = 17 inches, l = 44 inches, and ∠L = 153°. The possible value of ∠M is approximately 12.3°.

In any triangle, the sum of the interior angles is always 180°. First, we can find the third angle ∠K by subtracting ∠L from 180°: 180° - 153° = 27°. Next, we use the Law of Sines to find the possible values of ∠M. The formula is:

(sin ∠M) / m = (sin ∠K) / l

Plug in the given values:

(sin ∠M) / 17 = (sin 27°) / 44

To find sin ∠M, we multiply both sides by 17:

sin ∠M = (sin 27°) * (17 / 44)

Now, find the inverse sine (arcsin) of the result:

∠M = arcsin((sin 27°) * (17 / 44))

Three times a week tina walks 3/10 mile from school to library studies for 1 hour and then walks home 4/10 mile home. how much more will she need to walk to win a prize

Answers

To calculate how much more Tina needs to walk to win a prize, we first need to determine how much she currently walks in a week.

Tina walks 3/10 mile from school to the library three times a week, which is a total of 3/10 x 3 = 9/10 mile. She also walks 4/10 mile home, three times a week, which is a total of 4/10 x 3 = 12/10 miles.

Therefore, Tina currently walks a total of 9/10 + 12/10 = 21/10 miles in a week.

To determine how much more Tina needs to walk to win a prize, we need to know the criteria for winning the prize. If the prize requires walking a certain number of miles in a week, we can subtract 21/10 miles from the required number of miles to find out how much more Tina needs to walk.

The slant height if the cone is 13 cm. What is the volume of a cone having a radius of 5 cm and a slant height of 13 cm.

Answers

The formula for the volume of a cone is:

V = (1/3)πr^2h

where r is the radius of the base of the cone and h is the height of the cone.

We are given that the radius of the cone is 5 cm and the slant height is 13 cm. We can use the Pythagorean theorem to find the height of the cone:

h^2 = l^2 - r^2

where l is the slant height of the cone. Substituting the given values, we get:

h^2 = 13^2 - 5^2

h^2 = 144

h = 12

Now we can substitute the values of r and h into the formula for the volume of the cone:

V = (1/3)πr^2h

V = (1/3)π(5^2)(12)

V = (1/3)π(25)(12)

V = (1/3)π(300)

V = 100π

Therefore, the volume of the cone is 100π cubic centimeters.

among american women aged 20 to 29 years, 10% are less than 60.8 inches tall, 80% are between 60.8 and 67.6 inches tall, and 10% are more than 67.6 inches tall.17 assuming that the height distribution can ade- quately be approximated by a normal curve, find the mean and standard deviation of the distribution

Answers

Answer:

mean height is approximately 64.2standard deviation is approximately 3.4 inches

Step-by-step explanation:

Since the distribution is approximately normal, we can use the empirical rule to estimate the mean and standard deviation.

According to the empirical rule:

Approximately 68% of the data falls within 1 standard deviation of the mean

Approximately 95% of the data falls within 2 standard deviations of the mean

Approximately 99.7% of the data falls within 3 standard deviations of the mean

From the information given in the problem, we know that:

10% of women are less than 60.8 inches tall

10% of women are more than 67.6 inches tall

So, we can estimate the mean height as the midpoint between 60.8 and 67.6:

mean = (60.8 + 67.6) / 2 = 64.2 inches

We also know that 80% of women are between 60.8 and 67.6 inches tall. Since this is approximately 1 standard deviation from the mean (on either side), we can estimate the standard deviation as:

standard deviation = (67.6 - 64.2) / 1 = 3.4 inches

Therefore, the mean height is approximately 64.2 inches and the standard deviation is approximately 3.4 inches.

What are your chances of winning a raffle in which 325 tickets have been sold, if you haveone ticket?

A quadratic expression has x + 4 and 4x + 9 as its linear factors. Between which values of


x can a zero of the associated quadratic function be found?

Answers

The range of x values between which a zero can be found is -9/4 < x < -4.

Since x + 4 and 4x + 9 are linear factors of the quadratic expression, the quadratic expression can be written as:

Q(x) = k(x + 4)(4x + 9)

where k is some constant.

To find the values of x for which Q(x) = 0, we can set each factor equal to zero and solve for x:

x + 4 = 0 --> x = -4

4x + 9 = 0 --> x = -9/4

Therefore, the zeros of Q(x) are x = -4 and x = -9/4.

To find the range of x values between which a zero can be found, we need to determine the sign of Q(x) in each of the three intervals:

1. x < -9/4

2. -9/4 < x < -4

3. x > -4

For x < -9/4, both x + 4 and 4x + 9 are negative, so Q(x) = k(negative)(negative) = k(positive), which is positive.

For x > -4, both x + 4 and 4x + 9 are positive, so Q(x) = k(positive)(positive) = k(positive), which is also positive.

For -9/4 < x < -4, x + 4 is positive and 4x + 9 is negative, so Q(x) = k(positive)(negative) = k(negative), which is negative.

Therefore, the range of x values between which a zero can be found is -9/4 < x < -4.

Answers

The value of the line integral is approximately 2.6173.

To evaluate the line integral, we need to parameterize the curve C and

compute the dot product of F and the tangent vector to C at each point

on the curve. Then we integrate the dot product over the interval of

parameterization.

Let's first find the tangent vector to the curve C. We have:

[tex]r(t) = (t^3, t^2, 3t)[/tex]

[tex]r'(t) = (3t^2, 2t, 3)[/tex]

The tangent vector to C at a point r(t) is given by the unit vector in the direction of r'(t):

[tex]T(t) = r'(t)/||r'(t)|| = (3t^2, 2t, 3)/\sqrt{(9t^4 + 4t^2 + 9)}[/tex]

Now we need to compute the dot product of F and T:

[tex]F(r(t)) . T(t) = (5 sin(t^3), -4 cos(t^2), 10t^4)/\sqrt{(9t^4 + 4t^2 + 9)}[/tex]

Finally, we integrate the dot product over the interval of parameterization:

[tex]\intcF. dr = \int0^1 F(r(t)) . T(t) dt[/tex]

[tex]= \int0^1 (5 sin(t^3), -4 cos(t^2), 10t^4)/\sqrt{(9t^4 + 4t^2 + 9) . (3t^2, 2t, 3) dt}[/tex]

[tex]= \int0^1 (15t^2 sin(t^3) - 8t^2 cos(t^2) + 30t^5) /\sqrt{ (9t^4 + 4t^2 + 9) dt}[/tex]

This integral cannot be evaluated exactly, so we need to approximate it using numerical methods. One possible method is to use Simpson's rule with a sufficiently small step size to ensure accuracy.

from sympy import

t = symbols('t')

F =[tex]Matrix([5*sin(t**3), -4*cos(t**2), 10*t**3])[/tex]

We also know that x and y are in a ratio of 4:13, which means we can write:

x = 4k

y = 13k

where "k" is a constant that we need to find.

Substituting these expressions for x and y into the equation, we get:

10 + 4k + 13k = 180

17k = 170

k = 10

Now we can find the values of x and y:

x = 4k = 4(10) = 40

y = 13k = 13(10) = 130

Therefore, the measures of the two angles in the ratio of 4:13 are 40 degrees and 130 degrees, respectively.

Solve the inequality -1/2x greater than or equal to 17. Graph the solution

Answers

To solve the inequality -1/2x ≥ 17, we can start by isolating x on one side of the inequality.

Multiplying both sides by -2 (and reversing the direction of the inequality since we are multiplying by a negative number), we get:

x ≤ -34

So the solution to the inequality is x ≤ -34.

To graph the solution, we can draw a number line and mark -34 on it. Then we shade all the values of x that are less than or equal to -34. This can be represented by a closed circle at -34 and a shaded line to the left of -34, indicating that any value of x in that range satisfies the inequality.

Here is a graph of the solution:

```

<=====(●)-----------------------

     -34

```

The shaded part of the line represents the values of x that satisfy the inequality -1/2x ≥ 17, and the closed circle at -34 indicates that x can be equal to -34 (since the inequality is "greater than or equal to").

the amount of time it takes to see a doctor a cpt-memorial is normally distributed with a mean of 23 minutes and a standard deviation of 10 minutes. what is the z-score for a 34 minute wait?

Answers

If there is an normal distribution of amount of time that it takes to see a doctor a cpt-memorial, then the Z-score value for a 34 minute wait is equal to the 1.1.

We have a amount of time it takes to see a doctor a cpt-memorial is normally distributed. Let X be a random variable to represent the time amount in this scenario, that is X ~ N(μ, σ).

Mean, [tex], \mu[/tex] = 23 minutes

Standard deviations, [tex] \sigma[/tex]

= 10 minutes

We have to calculate Z-score for 34 a minute wait. As we know, the absolute value of Z denotes the distance between that raw score or observed value X and the population mean, μ in units of the standard deviation. Mathematically, formula for Z-score is [tex]Z = \frac{ X - \mu } {\sigma} [/tex]

where, Z --> Z-score

X--> observed value

σ --> standard deviations

μ --> population mean

Here, X = 34 minutes so plug all known values, [tex]Z = \frac{34 - 23}{10}[/tex]

=> Z = 11/10 = 1.1

Hence, the required Z-score value is 1.1.

This table shows the time it takes students in Homeroom 203 to get to school each morning: 1 Time Less than 10 min 10-19 min 20-29 min 30-39 min 40-49 min 50 min or more Find the experimental probability of a student in this homeroom taking a certain number of minutes to get to school. Make a probability distribution for this data. Number of Students 3, 5, 10, 7, 2, 3​

Answers

Answer:

Step-by-step explanation:

To find the experimental probability of a student in Homeroom 203 taking a certain number of minutes to get to school, we need to divide the number of students who take that amount of time by the total number of students in the homeroom.

The total number of students in the homeroom is:

3 + 5 + 10 + 7 + 2 + 3 = 30

The probability of a student taking less than 10 minutes to get to school is:

3/30 = 0.1 or 10%

The probability of a student taking 10-19 minutes to get to school is:

5/30 = 0.166 or 16.6%

The probability of a student taking 20-29 minutes to get to school is:

10/30 = 0.333 or 33.3%

The probability of a student taking 30-39 minutes to get to school is:

7/30 = 0.233 or 23.3%

The probability of a student taking 40-49 minutes to get to school is:

2/30 = 0.066 or 6.6%

The probability of a student taking 50 minutes or more to get to school is:

3/30 = 0.1 or 10%

To make a probability distribution, we can list the possible outcomes (in this case, the time it takes to get to school) and their corresponding probabilities:

Time (min) Probability

Less than 10 0.1

10-19 0.166

20-29 0.333

30-39 0.233

40-49 0.066

50 or more 0.1

Note that the probabilities add up to 1, which is what we expect for a probability distribution.

What is equation?

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

let the cost of a cheesburger be x.

let the cost of a bag of chips be y

therefore, it is given that x + y = 3.75                ...........(i)

it is also given that 2x + 3y = 8.25                     ............(ii)

multiplying the equation in( i) by 2 we get 2x + 2y = 7.50     ......(iii)

subtracting the equation in iii) from the equation in ii) we get y = $0.75

Therefore ,the cost of a bag of chips is $0.75

Substituting the value of y found in (ii) we get x = 3.

therefore ,the cost of a cheeseburger is $3.

The segment lengths are given as follows:

6. AB = 15.

7. RS = 47.

How to obtain the length of segment TU?

The length of segment TU is obtained applying the trapezoid midsegment theorem, which states that the length of the midsegment of the trapezoid is equals to the mean of the length of the bases of the trapezoid.

For item 6, we have that the mean of AB = x and 29 is of 22, hence:

(x + 29)/2 = 22

x + 29 = 44

x = AB = 15.

The value of x in item 7 is obtained as follows:

3x + 5 = (2x + 15 + 6x - 37)/2

8x - 22 = 6x + 10

2x = 32

x = 16.

Hence the length of RS is given as follows:

RS = 2 x 16 + 15

RS = 47.

In AQRS, the measure of ZS=90°, the measure of ZQ=41°, and SQ = 94 feet. Find the length of QR to the nearest tenth of a foot. ​

Answers

The length of QR to the nearest tenth of a foot is approximately 92.3 feet.

To find the length of QR in AQRS, we can use the Law of Cosines. This formula relates the lengths of the sides of a triangle to the cosine of one of its angles. In this case, we want to find QR, which is opposite the known angle ZQ.

So, let's write the formula:

QR² = SQ² + QS² - 2(SQ)(QS)cos(ZQ)

Substituting in the given values, we get:

QR² = 94² + QS² - 2(94)(QS)cos(41°)

We still need to find QS, but we can use the fact that ZS is a right angle to do so. Since ZQ and ZS are complementary angles (add up to 90°), we know that:

cos(ZQ) = sin(ZS)

So, we can rewrite the Law of Cosines formula as:

QR² = 94² + QS² - 2(94)(QS)sin(ZS)

Now we need to use the sine ratio to find QS. Since ZS is opposite the side SQ, we can write:

sin(ZS) = QS / SQ

Rearranging this equation gives:

QS = SQ sin(ZS)

Substituting in the values we know:

QS = 94 sin(90°)

Since sin(90°) = 1, we can simplify to:

QS = 94

Plugging this into our Law of Cosines equation:

QR² = 94² + 94² - 2(94)(94)sin(ZS)

QR² = 2(94)² - 2(94)²cos(41°)

QR² = 2(94)²(1 - cos(41°))

QR ≈ 92.3 feet (rounded to the nearest tenth)

A taho vendor having lost control of his cart down a slight hill runs after it in an attempt to keep it from running into a concrete wall however he did not get there in time and the 100 kg cart crashes assuming that in its downhill run the cart got a final velocity of 2m/s and that the impact stopped the cart in 0.15s, (a) determine the change in the cart's momentum (b) estimate the average force that the wall exerts on the cart (neglecting the angle of the hill) (c) determine the direction of the impulse that acted on the cart

Answers

(a) The change in the cart's momentum is -200 kg m/s.

(b) The average force that the wall exerts on the cart is 1333.33 N.

(c) The impulse that acted on the cart is in the opposite direction to the cart's initial momentum.

(a) The change in momentum can be calculated as the final momentum minus the initial momentum. The initial momentum of the cart is zero since it was at rest, and the final momentum is calculated as (mass of cart) x (final velocity) = 100 kg x 2 m/s = 200 kg m/s. Therefore, the change in momentum is -200 kg m/s.

(b) The average force can be calculated using the impulse-momentum theorem, which states that the impulse acting on an object is equal to the change in its momentum. The impulse is calculated as (mass of cart) x (final velocity - initial velocity) = 100 kg x (2 m/s - 0 m/s) = 200 kg m/s.

The time taken for the cart to come to a stop is given as 0.15 s. Therefore, the average force exerted by the wall is 1333.33 N.

(c) The direction of the impulse is opposite to the initial momentum of the cart, which was in the direction of the hill. Since the cart was moving downhill, the impulse that acted on it was in the upward direction.

Shannon's net worth is $872. 17 and her liabilities are $15,997. If she pays off a credit card with a balance of $7,698, what is her new net worth?

Answers

Answer:

To calculate Shannon's new net worth after paying off her credit card, we need to subtract the credit card balance from her total liabilities, and then subtract the result from her net worth:

New liabilities = $15,997 - $7,698 = $8,299

New net worth = $872.17 - $8,299 = -$7,426.83

Based on these calculations, Shannon's new net worth would be -$7,426.83 after paying off her credit card. This indicates that her liabilities still exceed her assets, and she would need to continue working towards reducing her debt and increasing her net worth over time.
