The maximum area of the quadrilateral is achieved when it is a square with a side length of 50cm, resulting in an area of 2500cm².
This is because a square has equal sides and equal angles,
resulting in the most efficient use of the perimeter to enclose the maximum area.
To see why, consider a rectangle with a perimeter of 200cm.
If the rectangle is long and thin, with one side much longer than the others,
then it will have a smaller area than a square with the same perimeter.
This is because the longer sides of the rectangle will be less effective at enclosing area than the shorter sides.
Hence, The maximum area of a quadrilateral with a minimum perimeter of 200cm is achieved when the quadrilateral is a square.

An airplane flies at 500 mph with a direction of 135* relative to the air. The plane experiences a wind that blows 60 mph with a direction of 60*
The plane's new velocity is 421.4 mph with a direction of 63.43 degrees relative to the air.
To solve this problem, we need to use vector addition. Let's first draw a diagram to represent the situation.
First, we need to break down the velocity of the plane and the velocity of the wind into their horizontal and vertical components.
The velocity of the plane can be broken down into a horizontal component of 500*cos(135) mph and a vertical component of 500*sin(135) mph.
The velocity of the wind can be broken down into a horizontal component of 60*cos(60) mph and a vertical component of 60*sin(60) mph.
Now, we can add these components together to get the resultant velocity.
The horizontal component of the resultant velocity is 500*cos(135) + 60*cos(60) = -189.28 mph. The negative sign indicates that the velocity is in the opposite direction of the plane's original direction.
The vertical component of the resultant velocity is 500*sin(135) + 60*sin(60) = 374.28 mph.
Using the Pythagorean theorem, we can find the magnitude of the resultant velocity:
|v| = sqrt((-189.28)^2 + (374.28)^2) = 421.4 mph.
Finally, we can find the direction of the resultant velocity using the inverse tangent function:
θ = tan^-1(374.28/-189.28) = -63.43 degrees.
So the plane's new velocity is 421.4 mph with a direction of 63.43 degrees relative to the air.

The sum of two numbers is 30. Determine the two numbers of their product is a maximum.
Answer:
Step-by-step explanation:
Let's call the two numbers x and y. We know that:
x + y = 30 (since the sum of the two numbers is 30)
We want to find the values of x and y that maximize their product, which is given by:
P = xy
To solve for x and y, we can use the fact that the sum of the two numbers is 30, so we can rewrite one of the numbers in terms of the other:
y = 30 - x
Substituting this into the equation for the product, we get:
P = x(30 - x)
Expanding this expression, we get:
P = 30x - x^2
To find the maximum value of P, we can take the derivative of this expression with respect to x and set it equal to zero:
dP/dx = 30 - 2x = 0
Solving for x, we get:
x = 15
So one of the numbers is x = 15, and the other is y = 30 - x = 15.
To confirm that this gives the maximum product, we can take the second derivative of P with respect to x:
d2P/dx2 = -2
Since the second derivative is negative, this means that the function P = 30x - x^2 has a maximum at x = 15.
Therefore, the two numbers are 15 and 15, and their product is maximized at P = 15 * 15 = 225.

For the class party, Josue and Pho each brought 1 3/5 liters of lemonade. How many liters of lemonade did they bring altogether?
Josue and Pho brought 3 1/5 liters of lemonade altogether
Josue and Pho brought 1 3/5 liters of lemonade each, so the total amount of lemonade they brought is:
1 3/5 + 1 3/5 = 3 1/5
To add the two mixed numbers, we first need to find a common denominator. In this case, the common denominator is 5. Then we convert both mixed numbers into fractions with a denominator of 5:
1 3/5 = (5 × 1 + 3) / 5 = 8/5
1 3/5 = (5 × 1 + 3) / 5 = 8/5
Now we can add the fractions:
8/5 + 8/5 = (8 + 8) / 5 = 16/5
Finally, we can convert the fraction back to a mixed number:
16/5 = 3 1/5
Therefore, Josue and Pho brought 3 1/5 liters of lemonade altogether.

Find a function f(x, y, z) such that V f is the constant vector (3,9,4). (Use symbolic notation and fractions where needed. Use C for the constant of integration.) f(x, y, z) =
The function f(x, y, z) that has the constant gradient vector (3, 9, 4) is: f(x, y, z) = (3/2)x^2 + (9/2)y^2 + (2z - y - 2x)^2 + C where C is a constant of integration.
To find a function f(x, y, z) such that the gradient of f, ∇f, is the constant vector (3, 9, 4), we can use the fact that the gradient of a function points in the direction of maximum increase and that the components of the gradient give the rates of change in the corresponding directions.
Let's assume that f(x, y, z) has the form:
f(x, y, z) = ax^2 + by^2 + cz^2 + dxy + exz + fyz + gx + hy + iz + C
where a, b, c, d, e, f, g, h, i, and C are constants that we need to determine.
The gradient of f is:
∇f = (2ax + dy + ez + g, 2by + dx + fz + h, 2cz + ex + fy + i)
If ∇f is equal to the constant vector (3, 9, 4), then we can set up a system of equations:
2ax + dy + ez + g = 3
2by + dx + fz + h = 9
2cz + ex + fy + i = 4
We need to solve this system of equations for a, b, c, d, e, f, g, h, i, and C.
To make the solution simpler, we can set some of the constants to zero. Let's set d = e = f = g = h = i = 0. Then the system becomes:
2ax + ez = 3
2by + fz = 9
2cz + fy = 4
Now we can solve for a, b, and c:
a = 3/2x - 1/2z
b = 9/2y - 1/2z
c = 2z - y - 2x
Substituting these values back into the original equation for f, we get:
f(x, y, z) = (3/2)x^2 + (9/2)y^2 + (2z - y - 2x)^2 + C
So the function f(x, y, z) that has the constant gradient vector (3, 9, 4) is:
f(x, y, z) = (3/2)x^2 + (9/2)y^2 + (2z - y - 2x)^2 + C

Patricia bought 4 apples and 9 bananas for $12. 70 Jose bought 8 apples and I bananas for $17. 70 at the same grocery store What is the cost of one apple?
The cost of one apple is $2.15.
To find the cost of one apple, we can set up a system of equations with the given information. Let's use A for the cost of one apple and B for the cost of one banana:
1) 4A + 9B = $12.70
2) 8A + B = $17.70
Now, we can solve this system of equations. We can multiply equation 1 by 2 to match the number of apples in equation 2:
1) 8A + 18B = $25.40
Now subtract equation 2 from the modified equation 1:
(8A + 18B) - (8A + B) = $25.40 - $17.70
17B = $7.70
Now, divide by 17 to find the cost of one banana:
B = $7.70 / 17 = $0.45
Now that we know the cost of one banana, we can substitute B in equation 2 to find the cost of one apple:
8A + ($0.45) = $17.70
8A = $17.25
A = $17.25 / 8 = $2.15
So, the cost of one apple is $2.15.

Austin spends a winter day recording the temperature once every three hours for science class. At 9 am, the temperature was -1.9°F. Between 9am and noon, the temperature rose 11.3°F. Between noon and 3pm, the temperature dropped 7.9°F. Between 3pm and 6pm, the temperature dropped 12.7°F. What was the temperature at 6pm?
To find the temperature at 6pm, we need to start with the temperature at 9am and then add or subtract the changes in temperature that occurred during the day.
We know that the temperature at 9am was -1.9°F. Between 9am and noon, the temperature rose 11.3°F, so at noon the temperature was:
-1.9 + 11.3 = 9.4°F
Between noon and 3pm, the temperature dropped 7.9°F, so at 3pm the temperature was:
9.4 - 7.9 = 1.5°F
Between 3pm and 6pm, the temperature dropped 12.7°F, so at 6pm the temperature was:
1.5 - 12.7 = -11.2°F
Therefore, the temperature at 6pm was -11.2°F.

10 foot ladder is leaning against a vertical wall when Jack begins
pulling the foot of the ladder away from the wall at a rate of 0.5
fr/s. how fast is the top of the ladder sliding down the wall?
We can use the Pythagorean theorem to relate the distances between the ladder, wall, and ground. Let's call the distance from the foot of the ladder to the wall "x", and the distance from the top of the ladder to the ground "y". Then, we know that:
x^2 + y^2 = 10^2
We can differentiate this equation with respect to time to get:
2x(dx/dt) + 2y(dy/dt) = 0
We're interested in finding dy/dt, the rate at which the top of the ladder is sliding down the wall. We know that dx/dt = 0.5 ft/s, so we can plug in these values and solve for dy/dt:
2x(dx/dt) + 2y(dy/dt) = 0
2(8)(0.5) + 2y(dy/dt) = 0 (since x = 8 based on the Pythagorean theorem)
dy/dt = -4 ft/s
So the top of the ladder is sliding down the wall at a rate of 4 ft/s.
When the 10-foot ladder is leaning against a vertical wall, it forms a right-angled triangle with the wall and the ground. As Jack pulls the foot of the ladder away from the wall at a rate of 0.5 ft/s, the top of the ladder slides down the wall. To find the rate at which the top of the ladder slides down, we can use the Pythagorean theorem:
a^2 + b^2 = c^2
where a is the distance from the foot of the ladder to the wall, b is the height of the ladder's top from the ground, and c is the length of the ladder (10 feet).
Differentiating both sides with respect to time (t), we get:
2a(da/dt) + 2b(db/dt) = 0
We know that da/dt = 0.5 ft/s. We need to find db/dt, which is the rate at which the top of the ladder slides down the wall. To do this, we need to find the values of a and b at a given moment. Since the problem doesn't provide this information, it's not possible to determine the exact value of db/dt. However, if you have the values of a and b, you can plug them into the equation and solve for db/dt.

Rote tells the little monsters to do an overhead press every $12$ seconds and a squat every $30$ seconds. (For example, they should do their first squat $30$ seconds into the drill.)
How many times during the $200$ second drill should the little monsters do an overhead press and a squat at the same instant?
The number of times that the little monsters will do an overhead press and a squat at the same instant during the drill is: 3 times
How to solve Prime Factorization Problems?We are told that, Rote tells the little monsters to carry out an overhead press every 12 seconds and then also a squat every 30 seconds.
Thus, prime factorization of 12: 2² x 3.
Thus, prime factorization of 30: 2 x 3 x 5.
For us to get the least common multiple, we will have to find the highest power of each of the prime factors that show up in either factorization. Therefore, we can say that the smallest common multiple of 12 and 30 are: 2² x 3 x 5 = 60
This tells us that the little monsters will carry out an overhead press and then a squat at the same instant for every 60 seconds.
For us to find how many times this will occur during the 200-second drill, we will then divide 200 by 60:
200 ÷ 60 = 3 remainder 20
This tells us that there will exist 3 complete cycles of both of the exercises during the 200-second drill, with an additional 20 seconds left over.
Therefore, we can say that the little monsters will do an overhead press and a squat at the same instant 3 times during the drill.

Molly has 250 trading cards. she gives n trading cards to her friend carol. marcus has 430 trading cards. he gives away three times as many cards as molly does. how many trading cards did molly give away if molly and marcus have the same number of trading cards left?
a.) 70 trading cards
b.) 80 trading cards
c.) 90 trading cards
d.) 180 trading cards
Molly gave away 90 trading cards, which is option (c).
Let's start by figuring out how many trading cards Marcus gave away. We know that Molly gave away n trading cards, so she has 250 - n cards left. Marcus gave away three times as many cards as Molly did, so he gave away 3n cards. That means he has 430 - 3n cards left.
We also know that Molly and Marcus have the same number of trading cards left, so:
250 - n = 430 - 3n
Simplifying and solving for n, we get:
2n = 180
n = 90
Therefore, Molly gave away 90 trading cards, which is option (c).

Determine how long it will take for 650 mg of a sample of chromium-51, which has a half life of 28 days, to decay to 200 mg.
It will take approximately 60.9 days for 650 mg of chromium-51 to decay to 200 mg.
What is Equation ?
An equation is a mathematical statement that shows that two expressions are equal. It typically contains variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division.
The decay of a radioactive substance can be modeled by the following equation:
N(t) = N₀ * [tex](1/2)^{(t/T) }[/tex]
where:
N(t) is the amount of the substance remaining after time t
N₀ is the initial amount of the substance
T is the half-life of the substance
We can use this equation to find how long it will take for 650 mg of chromium-51 to decay to 200 mg.
Let's first find the decay constant (λ) for chromium-51:
λ = ㏒(2) ÷ T = ㏒(2) ÷ 28 = 0.0248 (rounded to 4 decimal places)
Now we can use the equation:
N(t) = N₀ * [tex]e^{(-λ*t)}[/tex]
We know that N₀ = 650 mg and N(t) = 200 mg, so we can solve for t:
200 = 650 * [tex]e^{(-0.0248*t)}[/tex]
Dividing both sides by 650:
0.3077 = [tex]e^{(-0.0248*t)}[/tex]
Taking the natural logarithm of both sides:
㏒(0.3077) = -0.0248*t
Solving for t:
t = ㏒(0.3077) : (-0.0248) ≈ 60.9 days
Therefore, it will take approximately 60.9 days for 650 mg of chromium-51 to decay to 200 mg.

You are building a fence for your pasture. the length is three more than four times the width
The perimeter of the fence for the pasture is 10W + 6.
To find the perimeter of the fence, we need to add up the lengths of all four sides. Let's start by using the given information to find the length and width of the pasture.
Let's say the width of the pasture is W. Then, according to the problem, the length of the pasture is 3 more than 4 times the width, which can be expressed as:
Length = 4W + 3
Now that we have the length and width, we can find the perimeter by adding up all four sides:
Perimeter = 2(Length + Width)
Perimeter = 2(4W + 3 + W)
Perimeter = 2(5W + 3)
Perimeter = 10W + 6
Therefore, the perimeter of the fence is 10W + 6.
Note: The question is incomplete. The complete question probably is: You are building a fence for your pasture. The length is three more than four times the width. What is the perimeter of the fence.

|1 - 16| = 15
|3 - 16| = 13
|10 - 16| = 6
|12 - 16| = 4
|12 - 16| = 4
|15 - 16| = 1
|17 - 16| = 1
|18 - 16| = 2
|22 - 16| = 6
|66 - 16| = 50
MAD = (16 + 15 + 13 + 6 + 4 + 4 + 1 + 1 + 2 + 6 + 50) / 11

Answer: V = 2527.2 in^3
Step-by-step explanation:
V = Bh
that is, Volume = base area x height
the base area is the hexagon, and the height is given as 12.
Think of dividing the hexagon into 6 equal triangles, with height 7.8
so the area of all 6 triangles, (effectively the area of the hexagon), will be:
6(0.5 x 9 x 7.8) = 210.6 in^2
multiply this by the height to get the volume:
210.6 x 12 = 2527.2 in^3
thats it!
V = 2527.2 in^3
in a recent poll, 410 people were asked if they liked dogs, and 12% said they did. find the margin of error for this poll, at the 95% confidence level. give your answer to four decimal places if possible.
The margin error for the given poll having 95% confidence level with sample size of 410 is equal to 3.15%.
Sample size n = 410
Confidence level = 95%
Margin of error for this poll, use the formula,
ME = Z× (√(p₁(1-p₁) / n))
where Z is the z-score corresponding to the desired level of confidence.
p₁ is the sample proportion = 0.12
Using attached z-score table,
For a 95% confidence level, the corresponding z-score is 1.96.
Substituting the given values, we get,
ME = 1.96 × (√(0.12× (1-0.12) / 410))
Simplifying the expression inside the parentheses, we get,
⇒ME = 1.96 × 0.0160
⇒ME = 0.0315
Margin of error for this poll at the 95% confidence level is approximately 0.0315.
Therefore, 95% confidence level represents that the true proportion of people who like dogs is within 3.15% of the observed proportion of 12%.

A license plate is made of three letters and three numbers, how many different license plates are possible?
There are 17,576,000 different license plates possible, considering 26 letters (A-Z) and 10 numbers (0-9).
There are 26 options for each of the three letters and 10 options for each of the three numbers. Therefore, using the multiplication principle, the total number of possible license plates is 26 x 26 x 26 x 10 x 10 x 10 = 17,576,000.
Alternatively, we can use the permutation formula to calculate the number of arrangements: P(26,3) x P(10,3) = 15,600 x 720 = 11,251,200.
However, since order does not matter in a license plate, we need to divide by the number of permutations of three letters and three numbers, which is 3! x 3! = 36, resulting in 11,251,200 / 36 = 17,576,000 possible license plates.
