Transferring ownership of real property (land and buildings) can happen in a variety of ways, and it is not necessarily consensual.
A transfer can occur, for example, through eminent domain, in which the government takes private property for public use and compensates the owner for its worth. Transfers can also occur through foreclosure, which occurs when a borrower fails on a loan and the lender takes control of the property.
Regardless of the conditions, the legal steps for transferring ownership usually include execution, delivery, acceptance, and recording. The signing of a legal instrument that transfers ownership is referred to as execution. The transfer of custody or control of the property to the new owner is referred to as delivery. The new owner's agreement to accept the transfer is referred to as acceptance.

A bicycle wheel is 63m in diameter. how many metres does the bicycle travel for 100 revolutions of the wheel. (pie=²²/⁷
Answer:
19782m
Step-by-step explanation:
1 revolution = circumference
circumference = π * diameter
π = 3.1416
Then
circumference = 3.1416 * 63
= 197.92m
1 revolution = 197.82m
100 revolutions = 100*197.82m
= 19782m
Answer:
19.8 km
Step-by-step explanation:
To find:-
The distance travelled in 100 revolutions .Answer:-
We are here given that,
diameter = 63mWe can first find the circumference of the wheel using the formula,
[tex]:\implies \sf C = 2\pi r \\[/tex]
Here radius will be 63/2 as radius is half of diameter. So on substituting the respective values, we have;
[tex]:\implies \sf C = 2\times \dfrac{22}{7}\times \dfrac{63}{2} \ m \\[/tex]
[tex]:\implies \sf C = 198\ m \\[/tex]
Now in one revolution , the cycle will cover a distance of 198m . So in 100 revolutions it will cover,
[tex]:\implies \sf Distance= 198(100)m\\[/tex]
[tex]:\implies \sf Distance = 19800 m \\[/tex]
[tex]:\implies \sf Distance = 19.8 \ km\\[/tex]
Hence the bicycle would cover 19.8 km in 100 revolutions.

Find the equation for the circle with a diameter whose endpoints are (3,1) and (-2,3)
Answer:
Step-by-step explanation:
The center of the circle is the midpoint of the diameter. To find the midpoint, we use the midpoint formula:
Midpoint = [(x1 + x2)/2, (y1 + y2)/2]
where (x1, y1) and (x2, y2) are the coordinates of the endpoints of the diameter.
Midpoint = [(3 + (-2))/2, (1 + 3)/2]
Midpoint = [1/2, 2]
So, the center of the circle is (1/2, 2).
The radius of the circle is half the length of the diameter. To find the length of the diameter, we use the distance formula:
Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
where (x1, y1) and (x2, y2) are the coordinates of the endpoints of the diameter.
Distance = sqrt((-2 - 3)^2 + (3 - 1)^2)
Distance = sqrt(25 + 4)
Distance = sqrt(29)
So, the length of the diameter is sqrt(29).
The radius of the circle is half of sqrt(29), which is sqrt(29)/2.
Therefore, the equation of the circle is:
(x - 1/2)^2 + (y - 2)^2 = (sqrt(29)/2)^2
Simplifying this equation, we get:
(x - 1/2)^2 + (y - 2)^2 = 29/4
So, the equation of the circle with a diameter whose endpoints are (3, 1) and (-2, 3) is (x - 1/2)^2 + (y - 2)^2 = 29/4.

What is the meaning of "permutations that preserve distances"?
Answer: Permutations that preserve distances are also known as isometries or distance-preserving transformations.
Step-by-step explanation:
Permutations that preserve distances refer to a type of mathematical transformation that preserves the distances between pairs of points in a geometric space. In other words, if you have a set of points arranged in a particular way and you apply a permutation that preserves distances, the resulting arrangement of points will have the same distances between each pair of points as the original arrangement. This type of permutation is important in geometry and can be used to study properties of geometric objects such as polyhedra, graphs, and other structures. Permutations that preserve distances are also known as isometries or distance-preserving transformations.
a cliff diver plunges from a height of 81 ft above the water surface. the distance the diver falls in t seconds is given by the function d(t)
(a) Therefore after t = 1.75 seconds the diver will hit the water.
(b) The velocity the diver hit the water is 56 ft/s.
From the given condition we have d(t) = 16t²
and the height is 49ft
(a) Now when the diver hit the water the equation become
16t² = 49
t² = 49/16
t = ±7/4
t = ±1.75
since time can not be negative so t = 1.75
Therefore after t = 1.75 seconds the diver will hit the water.
(b)
Now differentiating d(t) with respect to t we get
d'(t) = 32t
now putting t=7/4 we get
the velocity d'(7/4) = 32*7/4
d'(7/4) = 56ft/s
Therefore the velocity the diver hit the water is 56 ft/s.

A commuter railway has 800 passengers per day and charges each one two dollars per day. For each 4 cents that the fare is increased, 5 fewer people will go by train.
What is the greatest profit that can be earned?
Greatest profit = $_____
Answer:
Step-by-step explanation:
To find the greatest profit, we need to determine the fare that will maximize revenue, while also considering the decrease in ridership due to the fare increase.
Let's assume the initial fare is $2, and the number of passengers is 800 per day. So, the initial revenue is:
$2 x 800 = $1600 per day
Now, let's say we increase the fare by 4 cents to $2.04. According to the problem, for each 4 cents increase in fare, there will be 5 fewer passengers. So, the number of passengers will decrease to:
800 - (5 x 4) = 780 passengers per day
The new revenue at this fare will be:
$2.04 x 780 = $1591.20 per day
By increasing the fare, the revenue decreased. This means that we may have increased the fare too much. Let's try another fare.
If we increase the fare by 2 cents to $2.02, the number of passengers will decrease by:
800 - (5 x 2) = 790 passengers per day
The new revenue at this fare will be:
$2.02 x 790 = $1595.80 per day
This is more revenue than the initial fare of $2 per person. Let's continue this process:
If we increase the fare by another 2 cents to $2.04, the number of passengers will decrease by:
790 - (5 x 2) = 780 passengers per day
The new revenue at this fare will be:
$2.04 x 780 = $1591.20 per day
This is less revenue than the $2.02 fare, so we can stop here.
Therefore, the greatest profit can be earned by charging $2.02 per person per day, and the maximum revenue will be:
$2.02 x 790 = $1595.80 per day
This is a bit less than the initial daily revenue of $1600, but it is the most revenue we can get by increasing the fare without causing a significant reduction in ridership.
Answer:
$2205
Step-by-step explanation:
You want the greatest profit that can be earned by a commuter railway that has 800 passengers per day at a fare of $2, and 5 fewer for each 4¢ increase in the fare.
Ridership functionThe number of riders (q) as a function of price (p) can be described by ...
q = 800 -5(p -2)/0.04
q = 1050 -125p . . . . . . . simplified
Revenue functionThe daily revenue is the product of price and the number of riders who pay that price.
r = pq
r = p(1050 -125p)
r = 125p(8.40 -p)
Maximum revenueThis function describes a parabola that opens downward. It has zeros at p=0 and p=8.40. The vertex of the parabola is on the line of symmetry, halfway between the zeros:
pmax = (0 +8.40)/2 = 4.20
The maximum revenue is ...
r(4.20) = 125·4.20(8.40 -4.20) = 125(4.20²) = 2205
The maximum revenue that can be earned is $2205.
__
Additional comment
The ridership at that fare is 125(4.20) = 525.
Profit is the difference between revenue and cost. Here, we have no information about the cost function, so we cannot predict the maximum profit. The question seems to assume that profit is equal to revenue.

Answer:
The answer is 2.45 litres in one week.
Answer:
2.45 liters
Step-by-step explanation:
1 days - 350 ml of Milk
We know that, there are 7 days per week.
Therefore,
To find the milliliters of milk that she drinks in a week,
multiply milliliters of milk she drinks for a day by 7 ( number of days in a week).
Let us find it now.
350 ml × 7 = 2450 ml
And now to convert your answer into litres divide it by 1000.
2450ml ÷ 1000 = 2.45 liters
Assuming that the equation defines a differential function of x, find Dxy by implicit differentiation. 4)2xy-y2 = 1 5) xy + x + y = x2y2
For the equations 2xy - y^2 = 1 and xy + x + y = x^2y^2 using implicit differentiation the value Dxy is given by Dxy = (1 - 2xy + 3y^2)/(x - y)^3 and Dxy = (2y^2 - 2xy - 3y - 1)/(x - 2xy + 1)^3 respectively.
Equation 2xy - y^2 = 1,
Differentiate both sides of the equation with respect to x,
Treating y as function of x and then differentiate again with respect to x.
Using implicit differentiation,
First, differentiate both sides with respect to x,
2y + 2xy' - 2yy' = 0
Next, solve for y',
⇒2xy' - 2yy' = -2y
⇒y' (2x - 2y) = -2y
⇒y' = -y/(x - y)
Now, differentiate again with respect to x,
y''(x - y) - y'(2x - 2y) = y/(x - y)^2
Substitute the expression we obtained for y' in terms of y and x,
y''(x - y) - (-y/(x - y))(2x - 2y) = y/(x - y)^2
Simplify and solve for y'',
y''(x - y) + (2xy - 3y^2)/(x - y)^2 = 1/(x - y)^2
The expression for Dxy is,
Dxy = (1 - 2xy + 3y^2)/(x - y)^3
For the equation xy + x + y = x^2y^2,
Differentiate both sides of the equation with respect to x,
Using implicit differentiation,
First, differentiate both sides with respect to x,
⇒y + xy' + 1 + y' = 2xyy'
Solve for y',
⇒xy' - 2xyy' + y' = -y - 1
⇒y' (x - 2xy + 1) = -y - 1
⇒y' = -(y + 1)/(x - 2xy + 1)
Now, differentiate again with respect to x,
y''(x - 2xy + 1) - y'(2y - 2x y' + 1) = (y + 1)/(x - 2xy + 1)^2
Substitute the expression we obtained for y' in terms of y and x,
y''(x - 2xy + 1) - (-y - 1)/(x - 2xy + 1)^2 (2y - 2x y' + 1) = (y + 1)/(x - 2xy + 1)^2
Simplify and solve for y''
y''(x - 2xy + 1) - (2y^2 - 2xy - 2y)/(x - 2xy + 1)^2 = (y + 1)/(x - 2xy + 1)^2
The expression for Dxy is,
Dxy = (2y^2 - 2xy - 3y - 1)/(x - 2xy + 1)^3
Therefore , the value of Dxy using implicit differentiation for two different functions is equal to
Dxy = (1 - 2xy + 3y^2)/(x - y)^3 and Dxy = (2y^2 - 2xy - 3y - 1)/(x - 2xy + 1)^3

A dietician is planning a snack package of fruit and nuts. Each ounce of fruit will supply zero units of protein, 3 units of carbohydrates, and 2 unit of fat, and will contain 40 calories. Each ounce of nuts will supply 4 units of protein, 2 unit of carbohydrate, and 4 units of fat, and will contain 50 calories. Every package must provide at least 4 units of protein, at least 11 units of carbohydrates, and no more than 16 units of fat. Find the number of ounces of fruit and number of ounces of nuts that will meet the requirement with the least number of calories. What is the least number of calories?
Let x be the ounces of fruit and y be the ounces of nuts. What is the objective function that must by minimized?
z = __x + __y
The dietician should use ___ ounce(s) of fruit and ___ ounce(s) of nuts. These amounts will have a total of ___calories.
(Type your answer in whole numbers)
The objective function that must be minimized is:
z = 40x + 50y
subject to the constraints:
0x + 4y ≥ 4 (protein constraint)
3x + 2y ≥ 11 (carbohydrate constraint)
2x + 4y ≤ 16 (fat constraint)
We want to find the number of ounces of fruit (x) and nuts (y) that will meet the requirement with the least number of calories.
Solving the system of inequalities, we get:
x = 2 ounces
y = 2 ounces
Therefore, the dietician should use 2 ounces of fruit and 2 ounces of nuts. These amounts will have a total of 180 calories (402 + 502).
Answer:
Step-by-step explanation:
Let's assume we need x ounces of fruit and y ounces of nuts to meet the requirements with the least number of calories. Then, the problem can be expressed as an optimization problem:
Minimize: 40x + 50y (since we want to minimize the number of calories) Subject to:
0x + 4y ≥ 4 (we need at least 4 units of protein)3x + 2y ≥ 11 (we need at least 11 units of carbohydrates)2x + 4y ≤ 16 (we cannot have more than 16 units of fat)
To solve this problem, we can use the simplex method. First, we convert the problem to standard form by introducing slack variables:
Minimize: 40x + 50y Subject to:
0x + 4y + s1 = 43x + 2y + s2 = 112x + 4y + s3 = 16
Now we can create the initial simplex tableau:
xys1s2s3RHSs1041004s23201011s32400116z-40-500000
We want to find the minimum value of z, so we need to choose the variable with the most negative coefficient in the bottom row as the entering variable. In this case, that is y. We then choose the variable with the smallest non-negative ratio between the right-hand side and the coefficient of the entering variable in its row as the leaving variable. In this case, that is s3, since 16/4 = 4 is the smallest non-negative ratio.
We then perform the pivot operation to eliminate the coefficient of y in the other rows:
x y s1s2s3RHSs1001-214y3/2101/2-1/24s2-1001-1/25z-100025-15200
We repeat this process until all the coefficients in the bottom row are non-negative. The final tableau is:

It is known that the area of a triangle can be calculated by multiplying the measure of the base by the measure of the height. Let the triangle measure 5m, 12m and 13m. Determine your area
The area of this triangle is 30 m².
What area?Area is a surface measure, that is, it is the amount of space that a geometric figure occupies on a flat surface.
To calculate the area of a triangle, we can use the formula:
Area = (base x height) / 2
In the case of the given triangle, we can choose the measure of 5m as the base and the measure of 12m as the height, since the height forms a right angle with the base and is perpendicular to it.
So, we have:
Area = (b*h)/2
Area = (5m * 12m) / 2
Area = 30m²

The appropriate inference from the data is (B) Since [tex]20%[/tex] of this group read below grade level, we cannot draw any generalizations about the population. Thus, option B is correct.
What is the percent of the sample?A representative sample is a subset of data, often drawn from a wider population, that can show qualities that are similar.
Because the data produced contains more manageable, smaller representations of the larger group, representative sampling aids in the analysis of bigger groups.
Although the sample may be representative of seventh-grade American students, it is not necessarily representative of all seventh-graders or all American children. Hence, without additional data or research, we cannot extrapolate the sample's results to the overall population.
Therefore, 20%20, percent of all American students in seventh grade were reading below grade level.

d. A quantity increases by 25% each year for 3 years. How much is the combined percentage growth p over the three-year period?
When a quantity increases by 25%, the new quantity becomes 100% + 25% = 125% of the original quantity.
After the first year, the quantity has increased to 125% of its original value. After the second year, it increases an additional 25%, making the new value 125% + (25% of 125%) = 156.25% of the original value. Finally, after the third year, it increases by another 25%, making the new value 156.25% + (25% of 156.25%) = 195.3125% of the original value.
So the quantity has increased by 195.3125% - 100% = 95.3125% over the three-year period. Therefore, the combined percentage growth p over the three-year period is 95.3125%.

300 students attend Ridgewood Junior High School. 4% of students bring their lunch to school everyday. How many students brought their lunch to school on Thursday?
On Thursday, 12 students brought their lunch at school.
Define the term percentage?Using a number out of 100, a percentage is a technique to indicate a fraction or piece of a total. The word "percent" means "per hundred."
If 4% of the students bring their lunch to school every day, we can find the number of students who brought their lunch on Thursday by multiplying the total number of students by the percentage that brought their lunch:
Number of students who brought their lunch = (4/100) x 300
Number of students who brought their lunch = 12
Therefore, On Thursday, 12 students brought their lunch at school.
