The distance between the factories is approximately 1704 meters.
To solve this problem, we can use the Law of Cosines. Let's denote the distance between the man and Factory 1 as x, the distance between the man and Factory 2 as y, and the distance between the factories as z.
Given that the time difference for the man to hear the blasts from Factory 1 and Factory 2 is 4.2 seconds and 5.9 seconds respectively, we can calculate x and y using the speed of sound (344 m/s):
x = 4.2 seconds * 344 m/s = 1444.8 meters
y = 5.9 seconds * 344 m/s = 2030.4 meters
Now, we apply the Law of Cosines using the given angle of 40.8°:
z² = x² + y² - 2xy * cos(40.8°)
z² = 1444.8² + 2030.4² - 2(1444.8)(2030.4) * cos(40.8°)
z² ≈ 2904106.33
Take the square root to find the distance between the factories:
z ≈ √2904106.33 ≈ 1704.14 meters
Rounded to the nearest meter, the distance between the factories is approximately 1704 meters. However, this answer is not included in the given options. There might be an error in the question or the provided options.

The monthly payment for a new car priced at $29,950 with financing the 8% TT&L and making a 25% down payment at a current finance rate of 3.16% for 36 months is approximately $698.62.
How to find calculate the monthly payment?
To calculate the monthly payment for a new car priced at $29,950 with the current finance rate of 3.16% for 36 months, we need to consider several factors, including the down payment and taxes.
First, we need to calculate the total cost of the car, including the taxes, title, and license (TT&L) fees. We can do this by adding 8% of the car's price ($29,950) to the price of the car, which comes to $32,346 ($29,950 + 8% of $29,950).
Next, we need to calculate the amount of the down payment. A 25% down payment on $32,346 comes to $8,086.50 ($32,346 x 0.25).
Subtracting the down payment from the total cost of the car gives us the amount we need to finance, which is $24,259.50 ($32,346 - $8,086.50).
Now, we can use a loan calculator to determine the monthly payment. Based on these figures, the monthly payment would be approximately $698.62 per month for 36 months.
In summary, to calculate the monthly payment for a new car priced at $29,950 with the current finance rate of 3.16% for 36 months, we need to consider the total cost of the car, including taxes and fees, the down payment, and the amount to be financed.

It takes a ship three hours to sail 72km with the current and 4 hours against it. Find the speed of the ship in still water and find the speed of the current
Answer:
The speed of the ship =21 km/h
Speed of the current = 3 km/h
Step-by-step explanation:
Let's denote the speed of the ship in still water as s and the speed of the current as c.
When the ship is traveling with the current, the effective speed is (s + c). (we have to sum up both the speeds) Therefore, in 3 hours, the ship can travel a distance of:
distance = speed × time = (s + c) × 3
We know that this distance is 72 km, so we can write:
(s + c) × 3 = 72
Simplifying this equation, we get:
s + c = 24
Similarly, when the ship is traveling against the current, the effective speed is (s - c). (The difference between the speeds). Therefore, in 4 hours, the ship can travel a distance of:
distance = speed × time = (s - c) × 4
We know that this distance is also 72 km, so we can write:
(s - c) × 4 = 72
Simplifying this equation, we get:
s - c = 18
We now have two equations:
s + c = 24 ; s - c = 18
We can solve for s and c by adding these two equations:
2s = 42
Therefore, s = 21 km/h.
Substituting this value of s into one of the equations above, we can solve for c:
s + c = 24
21 + c = 24
c = 3 km/h.
Therefore, the speed of the ship in still water is 21 km/h, and the speed of the current is 3 km/hs

The best estimate for the elk population is b) 1,250.
To estimate the elk population, you can use the mark and recapture method. The proportion of marked elk to the total marked population should be equal to the proportion of marked elk observed in the sample to the total observed population.
So, (marked elk / total marked population) = (marked elk observed / total observed population)
In this case: (75 / total population) = (15 / 250)
Now, solve for the total population:
75 / total population = 15 / 250
Cross-multiply:
15 * total population = 75 * 250
total population = (75 * 250) / 15
total population = 18,750 / 15

Answer:
Step-by-step explanation:
A boat heading out to sea starts out at point aa, at a horizontal distance of 1433 feet from a lighthouse/the shore. from that point, the boat’s crew measures the angle of elevation to the lighthouse’s beacon-light from that point to be 15∘. at some later time, the crew measures the angle of elevation from point bb to be 6∘. find the distance from point aa to point bb. round your answer to the nearest tenth of a foot if necessary.
The distance from point A to point B is approximately 13706.2 feet. Rounded to the nearest tenth of a foot, this is 164474.4 inches or 13706.2 / 12 ≈ 1142.2 feet.
Let's first draw a diagram to visualize the situation:
Lighthouse
|
| x
|
|
A ------------ B
y
In the diagram, A is the starting point of the boat, B is the point where the crew measures the angle of elevation to be 6 degrees, and Lighthouse is the location of the lighthouse. We are looking for the distance AB.
From point A, we can use the tangent of the angle of elevation to find the height of the lighthouse beacon above sea level:
tan(15°) = height / 1433 feet
height = 1433 feet * tan(15°) ≈ 383.6 feet
Similarly, from point B, we can find the height of the lighthouse beacon above sea level:
tan(6°) = height / (1433 feet + AB)
height = (1433 feet + AB) * tan(6°)
Now we can set these two expressions for height equal to each other, since they represent the same height:
1433 feet * tan(15°) = (1433 feet + AB) * tan(6°)
Multiplying both sides by the denominator of the right-hand side, we get:
1433 feet * tan(15°) = 1433 feet * tan(6°) + AB * tan(6°)
Subtracting 1433 feet * tan(6°) from both sides, we get:
AB * tan(6°) = 1433 feet * (tan(15°) - tan(6°))
Dividing both sides by tan(6°), we get:
AB = 1433 feet * (tan(15°) - tan(6°)) / tan(6°) ≈ 13706.2 feet
Therefore, the distance from point A to point B when rounded to the nearest tenth of a foot, this is 164474.4 inches or 13706.2 / 12 ≈ 1142.2 feet.

Frank just bought a refrigerator for 1036. He paid 103.60 in a down payment and will pay the rest in 4 equal installments. How much does he need to pay for each installment?
Frank needs to pay $233.10 for each installment.
How much per installment for refrigerator?To determine how much Frank still owes on the refrigerator after paying the down payment. We can subtract the down payment from the total cost of the refrigerator:
Total cost of refrigerator = $1036
Down payment = $103.60
Amount owed = Total cost of refrigerator - Down payment
Amount owed = $1036 - $103.60
Amount owed = $932.40
Next, we need to determine how much Frank will pay for each installment. Since he will pay the remaining balance in 4 equal installments, we can divide the amount owed by 4:
Amount owed = $932.40
Number of installments = 4
Amount per installment = Amount owed / Number of installments
Amount per installment = $932.40 / 4
Amount per installment = $233.10
Therefore, Frank needs to pay $233.10 for each installment to fully pay off the refrigerator. By breaking down the cost into smaller payments, Frank can manage his budget more effectively and avoid the burden of making a large payment all at once.

Pete's Market is a small local grocery store with only one checkout counter. Assume that shoppers arrive at the checkout lane according to a Poisson probability distribution, with an arrival rate of 13 customers per hour. The checkout service times follow an exponential probability distribution, with a service rate of 20 customers per hour. It is the manager's service goal to limit the waiting time prior to beginning the checkout process to no more than five minutes. After reviewing the waiting line analysis of his store, the manager of Pete's Market wants to consider one of the following alternatives for improving service. Option 1: Hire a second person to bag the groceries while the cash register operator is entering the cost data and collecting money from the customer. With this improved single-server operation, the service rate could be increased to 30 customers per hour. (Note: Although we hire one more person, it is still an M/M/1 queueing system, Because we do not operate a second counter but only hire a person to help with the first cashier counter, the service rate of the cashier improves. ) What are the arrival and service rates in Option 1
In Option 1, the arrival rate remains constant at 13 customers per hour. This means that, on average, 13 customers arrive at the checkout lane every hour, following a Poisson probability distribution.
However, the service rate in Option 1 increases to 30 customers per hour. This improvement is achieved by hiring a second person to assist the cashier in bagging groceries while the main cashier is occupied with entering cost data and collecting money from the customer. This essentially speeds up the overall service process, allowing more customers to be served within the same time frame.
The service rate of 30 customers per hour indicates that, on average, the cashier and the assistant can complete the checkout process for 30 customers in an hour. The service times still follow an exponential probability distribution, but with a faster rate of service compared to the initial service rate of 20 customers per hour.
By implementing Option 1, the manager aims to reduce the waiting time prior to the checkout process to no more than five minutes, thereby improving overall customer satisfaction and efficiency at Pete's Market.

The velocity of the velociraptor is 0.4 m/s [E] - 0.8 m/s [W] + 0.3 m/s [S] and the speed of the velociraptor is 2 m/s.
To calculate the speed of the velociraptor, we need to divide the total distance traveled by the total time taken:
Total distance = 5m + 10m + 3m + 2m = 20m
Total time = 10 seconds
Speed = Total distance / Total time
= 20m / 10s
= 2m/s
To calculate the velocity of the velociraptor, we need to consider both the magnitude of its speed and its direction. We can calculate the displacement by subtracting the final position from the initial position:
Displacement = (5m [E] + 10m [W] + 3m [S] + 2m [W])
= (5m [E] - 8m [W] + 3m [S])
= 5m [E] - 8m [W] + 3m [S]
Note that we have used negative sign for the distance traveled towards the west.
The time taken is 10 seconds.
Velocity = Displacement / Time taken
= (5m [E] - 8m [W] + 3m [S]) / 10s

In this case, the radius r and slant s are both 6 cm, and the height h of the cone can be found using the Pythagorean theorem: h = √(s^2 - r^2) = √(8^2 - 6^2) = √28 ≈ 5.29 cm.
So, the volume of the hemisphere is (2/3)π(6 cm)^3 = 72π/3 = 24π cubic cm, and the surface area is 2π(6 cm)^2 = 72π square cm.
The volume of the right cone is (1/3)π(6 cm)^2(5.29 cm) = 62.83π/3 ≈ 20.94π cubic cm, and the surface area is π(6 cm)^2 + π(6 cm)(8 cm) = 36π + 48π = 84π square cm.
Therefore, the total volume of the composite figure is 24π + 20.94π = 44.94π cubic cm, and the total surface area is 72π + 84π = 156π square cm.

One hospital has found that 13. 95% of its patients require specially equipped beds. If the hospital has 258 beds,
what percentage of the beds should be specially equipped if the hospital wishes to be "pretty sure" of having
enough of these beds? Assume that the hospital wants only a 5% chance that they could run short of these beds,
even when the hospital is fully occupied.
A) 19,5%
B) 18. 2%
C) 19. 0%
D) 21. 9%
E) 17,5%
The percentage of beds that should be specially equipped is 19.0%. The correct option is c.
To be "pretty sure" of having enough specially equipped beds, the hospital wants to have only a 5% chance of running short of these beds, even when the hospital is fully occupied. This means that the probability of having enough beds should be 95%.
Let x be the percentage of beds that should be specially equipped. Then the probability that a patient does not require a specially equipped bed is 100% - 13.95% = 86.05%.
The probability that all 258 beds are occupied by patients who do not require a specially equipped bed is (0.8605)^258 = 0.0501, which is about 5%.
Therefore, the probability that at least one patient requires a specially equipped bed is 1 - 0.0501 = 0.9499, which is about 95%.
We can set up an equation to solve for x:
0.9499 = 1 - (1 - x)^258
Solving for x, we get:
x = 19.0%
Therefore, the percentage of beds that should be specially equipped is 19.0%.
So the answer is C) 19.0%.

When he was 30, Kearney began investing $200 per month in various securities for his retirement savings. His investments averaged a 5. 5% annual rate of return until he retired at age 68. What was the value of Kearney's retirement savings when he retired? Assume monthly compounding of interest
Kearney's retirement savings when he retired at age 68, assuming monthly compounding of interest, was $429,336.69.
How much did Kearney save for retirement?To calculate Kearney's retirement savings at age 68, we need to use the formula for the future value of an annuity due, which is:
FV = PMT x [((1 + r/n[tex])^(n*t)[/tex] - 1) / (r/n)] x (1 + r/n)
Where:
FV is the future value of the annuityPMT is the monthly payment (in this case, $200)r is the annual interest rate (5.5%)n is the number of compounding periods per year (12, for monthly compounding)t is the number of years (38, from age 30 to age 68)Plugging in the numbers, we get:
FV = 200 x [((1 + 0.055/12[tex])^(12*38)[/tex] - 1) / (0.055/12)] x (1 + 0.055/12)
FV = $429,336.69
Therefore, Kearney's retirement savings at age 68 would be approximately $429,336.69, assuming he invested $200 per month in securities with an average annual return of 5.5% and monthly compounding of interest. It's important to note that this calculation assumes that Kearney did not withdraw any money from his retirement savings during the 38-year period. Additionally, the actual value of his retirement savings could be different based on fluctuations in the market and any fees or taxes associated with his investments.

volume of cylinders
1. The radius of the cylinder is 7. 05 cm
2. The length of the cylinder is 15, 384 meters
3. The radius of the big cylinder is 5. 64 cm
How to determine the valuesThe formula for the volume of a cylinder is expressed as;
V = πr²h
Such that;
r is the radius of the cylinderh is the height1. We have that volume = 2500 cm³
Height = 16cm
Substitute the values, we have;
2500 = π × r² × 16
Divide both sides by 16
r² = 49. 76
Find the square root
r = 7. 05 cm
2. Volume = 20000 cm³/100 = 200 meters
Radius = diameter/2 = 13/2 = 6.5cm = 0. 065 m
Substitute the values
200/0. 013 = h
Divide the values
h = 15, 384 meters
3. Volume = πr²h
Volume = 3.14 × 3.5² × 13
Volume = 500. 045 cm²
Then, substitute the values
500. 045 = 3.14 × r² × 5
r² = 31. 85
find the square root
r = 5. 64 cm

A bag contains five red socks and eight blue socks. Lucky reaches into the bag and randomly selects two socks without replacement. What is the probability that Lucky will get different colored socks? Express your answer as a common fraction. I will give brainliest if you give a full explanation, I have the answer but I need to know HOW to solve the problem!!!
A bag contains five red socks and eight blue socks. Lucky reaches into the bag and randomly selects two socks without replacement, the probability that Lucky will get different colored socks is 10/39.
We can divide the issue into two distinct possibilities and multiply them together to find a solution.
Let's start by thinking about the likelihood of choosing a red sock during the initial draw.
The likelihood of choosing a red sock on the first draw is 5/13 due to the fact that there are only five red socks among the total of thirteen socks (five red plus eight blue).
There are now twelve socks left in the bag after the first one is drawn, with four red and eight blue.
On the second draw, there is an 8/12 chance of choosing a blue sock, which is a different colour.
We add the probabilities together to determine the likelihood that both events (drawing a red sock first and a blue sock second) will occur:
(5/13) * (8/12) = 40/156 = 10/39
Therefore, the probability that Lucky will get different colored socks is 10/39.
