7 men have 7 wives. Each men and each women have 7 children. How many people are there
There are 105 people in total. Given that there are 7 men, 7 wives, and each couple has 7 children, we can calculate the total number of people by summing the number of men, wives, and children.
In this case, there are 7 men, 7 wives, and each couple has 7 children. The number of men and wives combined is 7 + 7 = 14. Since each couple has 7 children, there are 7 children for each couple, resulting in a total of 7 x 7 = 49 children. Therefore, the total number of people is 14 (men and wives) + 49 (children) = 63. Including the original 7 men and 7 wives, the grand total is 63 + 7 + 7 = 77 people.
To break down the calculation further, we can analyze each category. There are 7 men, and each man is married to one wife. Therefore, there are 7 wives. Each couple has 7 children, so for the 7 couples, there are 7 x 7 = 49 children. Combining the men, wives, and children, we have 7 + 7 + 49 = 63 people. Adding the original 7 men and 7 wives, the grand total is 63 + 7 + 7 = 77 people.
With 7 men, 7 wives, and each couple having 7 children, there are a total of 105 people. The calculation includes the men, wives, and children, resulting in a total of 63 people. Including the original 7 men and 7 wives, the final count is 77 people.

How long will it take me to travel a distance of 12 km at the average rate of 5m/s
To find out how long it will take to travel a distance of 12 km at an average rate of 5 m/s, we can use the formula for speed:
Speed = Distance / Time
Rearranging the formula to solve for time, we have:
Time = Distance / Speed
Substituting the values, we have:
Time = 12 km / 5 m/s
To perform the calculation, we need to convert the distance to meters since the speed is given in meters per second. There are 1000 meters in 1 kilometer, so 12 km is equal to 12,000 meters.
Now, we can substitute the values into the formula:
Time = 12,000 meters / 5 m/s
Dividing 12,000 by 5, we get:
Time = 2400 seconds
Therefore, it will take approximately 2400 seconds to travel a distance of 12 km at an average rate of 5 m/s.

Which statement must be true?
Two cyclists meet at the library and then go for a bike ride. The distance each person has traveled from her home at x hours from the start of the ride is linear, as shown.
Let's assume that cyclist A and B start at a distance x and y, respectively, from the library. Further, let's assume that cyclist A starts at t = 0. Then, the distance from the library for cyclist A at t hours after the start of the ride is represented by x + rt. The distance from the library for cyclist B at t hours after the start of the ride is represented by y + st.As the question says, the distance each person has traveled from her home at x hours from the start of the ride is linear. Thus, we can write their distances from the library as:dA(x) = x + rtdB(x) = y + st, where dA and dB represent the distance covered by cyclists A and B respectively.Now, if we want to find out the distance between the two cyclists at x hours after the start of the ride, we can use the following formula:distance between the two cyclists = dB(x) - dA(x)= (y + st) - (x + rt) = (y - x) + (s - r)tSince s and r are constants, the expression (y - x) + (s - r)t is linear with respect to t.

averi bought a 6 ounce can of pecans for 4.89 . what was the unit price
The unit price of the pecans is $0.815 per ounce (rounded to three decimal places).
To calculate the unit price, we divide the total cost of the item by the quantity purchased. In this case, Averi bought a 6-ounce can of pecans for $4.89.
To find the unit price, we divide the total cost ($4.89) by the quantity purchased (6 ounces):
Unit price = Total cost / Quantity purchased
= $4.89 / 6 ounces
To simplify the unit price, we can divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 4.89 and 6 is 3.
Dividing both the numerator and denominator by 3, we get: Unit price = ($4.89 / 3) / (6 ounces / 3)
= $1.63 / 2 ounces
Therefore, the unit price of the pecans is $0.815 per ounce (rounded to three decimal places). This means that Averi paid approximately $0.815 for each ounce of pecans she purchased.

9) Terry works at Smith Point County Park. If you are a resident and have a Green Key, Card you pay $9 to park and if you do not have a Green Key Card, you pay $20 to park. On one busy day in July, the beach had 10,867 cars park in their lot throughout the day. If they collected $169,820, how many cars parked that were residents with a Green Key and how many parked without the Green Key?
In order to determine the number of cars that were residents with a Green Key and the number of cars parked without the Green Key, we will use the following formula:
Let x be the number of residents with a Green Key who parked. Let y be the number of cars that parked without a Green Key.
We can set up two equations based on the information given in the problem:
x + y = 10,867 (the total number of cars parked in the lot)
9x + 20y = 169,820 (the total amount of money collected)
Solve for x using the first equation:
x + y = 10,867
x = 10,867 - y
substitute this value for x in the second equation
and solve for y:
9x + 20y = 169,8209(10,867 - y) + 20y
= 169,82097,803 - 9y + 20y
= 169,82011y
= 72,017y
= 6557.909
We can round this number to 6558 since you cannot park a fraction of a car.
So, approximately 6558 cars are parked without a Green Key.
To find the number of residents with a Green Key who parked, we can substitute y = 6558 into the equation:
x + 6558 = 10,867x
= 10,867 - 6558x
= 4309
So, approximately 4309 cars parked that were residents with a Green Key, while approximately 6558 cars parked without the Green Key.

Here's an explanation to help you understand the problem. Remy stands on the dock represented by point C. He plans to swim from C to A, then from A to B, and then from B back to C. Now, from Remy to the swim route AB¯¯¯¯¯¯¯¯, the shortest distance is 60 meters, which is measured from C to D.
From the diagram ,AC = x meters and BD = y meters Since Remy swims from C to A and then to B, he swims a distance equal to AB. Thus, the total distance that he swims can be given as follows: AB + BA + BC, where BA is equal to 2x, and BC is equal to 2y.Then, the distance that Remy swims can be given by AB + 2x + 2yNow, we know that Remy swims from C to D at a distance of 60 meters. Therefore, we can represent x in terms of y using the Pythagorean theorem as shown below:x² + y² = 60² ... (Equation 1)Also, we know that Remy plans to swim back to point C. Therefore, the total distance that he will swim is given by: AB + 2x + 2y + AC Substituting AB with 2x, we have:4x + 2y + AC ... (Equation 2)Also, substituting Equation 1 into Equation 2, we get:4x + 2y + √(3600 - y²)Simplify the expression by multiplying both sides by 2:8x + 4y + 2√(3600 - y²)Now, substituting 2x with AB and 2y with BD, we get:2(AB) + AB + 2(BD) + BD + 2√(3600 - y²)Simplify the expression:4AB + 4BD + 2√(3600 - y²)Therefore, the total distance that Remy swims is equal to:4AB + 4BD + 2√(3600 - y²)Therefore, the correct answer is 4AB + 4BD + 2√(3600 - y²).

SO, 3 is the value of x and y for triangle RSTU.Given, RSTU and MNOP are similar triangles. We are to find the scale factor of RSTU to MNOP and then find the values of x and y.
In similar triangles, the ratio of the corresponding sides are equal.
Let us find the scale factor of RSTU to MNOP by comparing the corresponding sides.
Scale factor RSTU to MNOP = RT/MN
We have RT = 4x - 10, and
MN = 2x + 5.
So,RT/MN = (4x - 10) / (2x + 5)
= 2(2x - 5) / (2x + 5)
The scale factor of RSTU to MNOP is 2(2x - 5) / (2x + 5).
For x and y, we need to find the value of x and y for triangle RSTU.
Let us write the corresponding sides and their ratios.
RT/PN
= 4x - 10 / 2y + 3RS/MP
= 6x - 7 / 4y - 5RU/PO
= 5x - 7 / 4y + 2
Since RSTU and MNOP are similar, the ratio of corresponding sides should be equal.
Hence,
4x - 10 / 2y + 3
= 6x - 7 / 4y - 54x - 10 * 4y - 5
= 2y + 3 * 6x - 7 * 4y - 54x - 10 * 4y - 5 + 2y + 3 * 4y - 5

= 6x - 14y - 4y - 8y - 15 - 3
= 6x - 14y - y-8y - 18
= 6x - 15y
Simplifying further,
6x - 15y + 8y
= 18 + 8y - 15y6x - 7y

The longevity of people living in a certain region is normally distributed with a standard
deviation of 14 years. What is the mean longevity in years if 30% of the people live longer
than 75 years?
The mean longevity of people in the region is approximately 82.336 years, as calculated by finding the z-score corresponding to the 30th percentile and using the formula for a normal distribution.
Given that the longevity of people in the region is normally distributed with a standard deviation of 14 years, we can determine the mean longevity by finding the z-score corresponding to the 30th percentile.
To find the z-score, we look up the corresponding value in the standard normal distribution table. The 30th percentile corresponds to a z-score of approximately -0.524.
Using the formula for a normal distribution:
z = (x - μ) / σ
Where z is the z-score, x is the value, μ is the mean, and σ is the standard deviation.
Rearranging the formula to solve for the mean, we have:
μ = x - (z * σ)
Substituting the known values, we get:
μ = 75 - (-0.524 * 14)
μ ≈ 75 + 7.336
μ ≈ 82.336
Therefore, the mean longevity of people in the region is approximately 82.336 years.

Distance Arnob travels = Distance Kathleen travels - Distance Arnob travels Arnob's speed = Kathleen's speedTherefore, using the distance formula:Distance = Rate x TimeD = RTWhere:D is the distanceR is the rateT is the timeIn this scenario, Arnob and Kathleen are moving towards each other, meaning the distance between them is getting shorter. We can add their speeds together to find the rate at which the distance between them is getting shorter. Rate = Arnob's speed + Kathleen's speed = 9 + 8 = 17Since we know the rate at which the distance between them is getting shorter, we can use the formula to find the time it would take for Arnob to catch up to Kathleen. Let's call this time "t".D = RTDistance = Distance between Arnob and Kathleen = 75 - 5 = 70R = Rate at which the distance is getting shorter = 17T = Time it would take for Arnob to catch up to KathleenTherefore,70 = 17tSolving for t:t = 70/17 ≈ 4.12 minutes

Find the area of triangle obc in terms of r and theta
The area of triangle OBC in terms of r and θ is (1/2) * r^2 * sin(θ), which simplifies to (1/2) * r^2.
To find the area of triangle OBC in terms of r and θ, we can utilize the formula for the area of a triangle: Area = (1/2) * base * height. In this case, the base of the triangle is the side BC, which has a length equal to r, and the height is the perpendicular distance from point O to side BC.
Considering that point O is the origin (0,0) and point B is located on the positive x-axis, the distance from the origin to the line BC is equal to the radius r. Thus, the height of the triangle is r.
To find the angle θ between the positive x-axis and the line BC, we can use trigonometry. Since the line BC forms an angle of θ with the positive x-axis, the perpendicular from point B to the x-axis creates a right triangle. Therefore, sin(θ) can be determined by dividing the height of the triangle (r) by the hypotenuse (also r), resulting in sin(θ) = r/r = 1.
Substituting the values into the formula for the area of a triangle, we have Area = (1/2) * r * r * 1 = (1/2) * r^2.
Therefore, the area of triangle OBC in terms of r and θ is (1/2) * r^2 * sin(θ), which simplifies to (1/2) * r^2.

Ethan looks up at an angle of 5 degrees and sees the goodyear blimp. If the blimps altitude is 1150 feet and its speed is 15mph,in how many minutes will the blimp be directly overhead of ethan? (1 mile = 5280ft. )
The blimp will be directly overhead of Ethan in 9.94 minutes.
To determine how long it will take for the blimp to be directly overhead of Ethan, we can use the information about the blimp's altitude and speed.
First, let's find the horizontal distance covered by the blimp in the time it takes to be directly overhead. Since the blimp is moving at a speed of 15 mph, we need to convert this to feet per minute:
15 mph * (5280 ft / 1 mile) * (1 hour / 60 minutes) = 1320 ft/minute
So, the blimp is moving at a rate of 1320 feet per minute horizontally.
Now, let's calculate the vertical distance the blimp needs to cover to be directly overhead of Ethan. This is equal to the altitude of the blimp, which is given as 1150 feet.
Since Ethan is looking up at an angle of 5 degrees, we can use trigonometry to find the horizontal distance covered by the blimp when it reaches the altitude of 1150 feet.
tan(5 degrees) = vertical distance / horizontal distance
We want to solve for the horizontal distance, so rearranging the equation:
horizontal distance = vertical distance / tan(5 degrees)
horizontal distance = 1150 ft / tan(5 degrees)
Using a calculator, we find:
horizontal distance ≈ 13129.01 ft
Now, we can determine the time it takes for the blimp to cover this horizontal distance at a rate of 1320 feet per minute:
time = horizontal distance / rate
time = 13129.01 ft / 1320 ft/minute
Calculating this, we get:
time ≈ 9.94 minutes
Therefore, the blimp will be directly overhead of Ethan in approximately 9.94 minutes.

The right triangle shown below is formed by joining three squares at their vertices. What
is the value of z, the side length of the bottom square?
We find: z = x Therefore, the value of z, the side length of the bottom square, is equal to the side length of the top square.
Let's assume the side length of the top square is x. Since the right triangle is formed by joining the squares at their vertices, the hypotenuse of the triangle is the diagonal of the top square.
In a square, the length of the diagonal is equal to the side length multiplied by the square root of 2. Therefore, the hypotenuse of the right triangle is x * √2.
The two legs of the right triangle are the side lengths of the squares adjacent to the hypotenuse. In this case, one leg is z, the side length of the bottom square.
Using the Pythagorean theorem, we have the equation:
z^2 + z^2 = (x * √2)^2
Simplifying the equation, we get:
2z^2 = 2x^2
Dividing both sides by 2, we have:
z^2 = x^2
Taking the square root of both sides, we find:
z = x
Therefore, the value of z, the side length of the bottom square, is equal to the side length of the top square.

Fancy Pineapple produces pineapple juice and canned pineapple rings. This year the company anticipates a demand of at least 36,000 pints of pineapple juice and 3,600 cans of pineapple rings. Each pint of pineapple juice requires 2 pineapples, and each can of pineapple rings requires 1 pineapple. The company anticipates using at least 72,000 pineapples for these products. Each pint of pineapple juice costs the company 16¢ to produce, and each can of pineapple rings costs 40¢ to produce. How many pints of pineapple juice and cans of pineapple rings should Fancy Pineapple produce to meet the demand and minimize total costs?
To meet the demand and minimize total costs, Fancy Pineapple should produce 18,000 pints of pineapple juice and 3,600 cans of pineapple rings.
By producing this quantity, the company can meet the demand for 36,000 pints of pineapple juice and 3,600 cans of pineapple rings while using the minimum number of pineapples and minimizing costs.
To determine the optimal production quantity, we need to consider the requirements for each product and the costs associated with production.
Since each pint of pineapple juice requires 2 pineapples and each can of pineapple rings requires 1 pineapple, the total number of pineapples needed for both products is 39,600 (36,000 pints + 3,600 cans).
Given that the company anticipates using at least 72,000 pineapples, this quantity is sufficient to meet the demand.
Next, we consider the costs. Each pint of pineapple juice costs 16¢ to produce, while each can of pineapple rings costs 40¢ to produce. To minimize costs, the company should produce the product with the lower cost per unit.
In this case, producing pineapple juice is more cost-effective as it costs 16¢ per pint compared to 40¢ per can of pineapple rings. Therefore, Fancy Pineapple should produce 18,000 pints of pineapple juice to meet the demand.
In summary, Fancy Pineapple should produce 18,000 pints of pineapple juice and 3,600 cans of pineapple rings to meet the demand for 36,000 pints of pineapple juice and 3,600 cans of pineapple rings while minimizing costs.
This production quantity ensures the optimal use of pineapples and takes into account the lower production cost per unit for pineapple juice compared to pineapple rings.
