The unit rate in acres of land planned by the workers per day is found is 16/35 acres.
What is meant by rate of doing work?Power refers to the rate of work completion. It is a measure of how much energy is used up each unit of time. The joule per second (J/s) is the unit of power in the SI system.Force applied across a distance is called work. Examples such work include dragging down a confined helium balloon, driving a vehicle up a steep hill, and lifting an article against the gravitational attraction of the Earth. Energy manifests mechanically as work.For the mentioned question-
Total acres of land planted = 2/5 acres.
Total time taken = 7/8 days.
Thus, unit rate in acres per day = Total acres of land planted / Total time taken
unit rate in acres per day = (2/5) / (7/8)
unit rate in acres per day = (2*8)/(5*7)
unit rate in acres per day = 16/35
Thus, unit rate in acres of land planned by the workers per day is found is 16/35 acres.

A neighborhood swimming pool is 12 meters longer than it is wide. It is surrounded by a 2 meter wide walkway. The walkway has a total area of 168 square meters. What are the dimensions of the swimming pool?
Let's assume the width of the swimming pool is "x" meters.
The length of the swimming pool would then be "x + 12" meters.
Considering the walkway surrounds the pool on all sides, the total width including the walkway would be "x + 2 + 2" meters (two sides of the walkway).
The total length, including the walkway, would be "x + 12 + 2 + 2" meters.
The area of the walkway is given as 168 square meters, which can be represented as:
Area of the walkway = Total area including the walkway - Area of the pool
168 = (x + 2 + 2) * (x + 12 + 2 + 2) - x * (x + 12)
168 = (x + 4) * (x + 16) - x^2 - 12x
168 = x^2 + 16x + 4x + 64 - x^2 - 12x
168 = 8x + 64
8x = 168 - 64
8x = 104
x = 104/8
x = 13
Therefore, the width of the swimming pool is 13 meters, and the length of the swimming pool is 13 + 12 = 25 meters.
How do you determine whether an equation is separable?
In order to determine whether an equation is separable, we need to look at its structure. A differential equation is called separable if it can be expressed in the form g(y)dy=f(x)dx, where g(y) and f(x) are functions of only y and x, respectively. If the equation can be written in this form, it can be solved by integrating both sides with respect to their respective variables.
Example of a separable equation: dy/dx = 2x/(1+y^2)
Here, we can rearrange the equation to put all y terms on one side and all x terms on the other:
dy/(1+y^2) = 2x dx
Then we can integrate both sides to get:
y = tan^-1 (x^2 + C), where C is the constant of integration.
If an equation cannot be written in separable form, it cannot be solved using this method.

Main Answer: If A ∩ B = { } , then the two sets are disjoint sets.
Supporting Answer: Two sets are called disjoint sets if they have no common elements. If the intersection of two sets A and B is null, it means they have no common elements. Mathematically, A ∩ B = { } implies that A and B are disjoint sets. The intersection of two sets, A and B, is the set of all elements that are common to both sets A and B. In other words, the intersection of A and B is the set containing all the elements that are in A and B. If A ∩ B is null, it means there are no common elements in A and B, and thus A and B are disjoint sets.

If there are outliers in a sample, which of the following is always true?a. Mean > Median
b. Standard deviation is smaller than expected (smaller than if there were no outliers)
c. Mean < Median
d. Standard deviation is larger than expected (larger than if there were no outliers)
In the presence of outliers in a sample, the statement that is always true is d. Standard deviation is larger than expected (larger than if there were no outliers).
Outliers are extreme values that are significantly different from the other data points in a sample. These extreme values have a greater impact on the standard deviation compared to the mean or median. As a result, the standard deviation increases when outliers are present. Therefore, option d is the correct answer.
To summarize, when outliers are present in a sample, the standard deviation is typically larger than expected, while the relationship between the mean and median can vary and is not always predictable.

The Value of the double integral is 9/2.
To Evaluate the double integral ∫∫D x dA, we need to express the region D as a type I or type II region, and then integrate over that region.
For D enclosed by the lines y = x, y = 0, x = 3, we can see that the region is a right triangle with vertices at (0,0), (3,0), and (3,3), so it can be expressed as a type I region with:
a. D = {(x, y) | y ≤ x ≤ 3, 0 ≤ y ≤ x}
or as a type II region with:
b. D = {(x, y) | 0 ≤ y ≤ 3, y ≤ x ≤ 3}
To evaluate the double integral using either of these regions, we can use iterated integrals.
Using a type I region:
∫∫D x dA = ∫0³ ∫y³ x dy dx
= ∫0³ ∫0x x dy dx
= ∫0³ ½x² dx
= 9/2
Using a type II region:

Answer:
x = 122°
Step-by-step explanation:
There is remote angle( non- adjecent angle) and their sum equal to the exterior angle .
Exterior angle is an angle formed from one side of the polygone and the extended side so
<A and <B are remot angle and <BCD is exterior angle .
And we write the equetion as
<A + <B = <BCD
58° + 64° = x°
122° = X°
so the exterior angle ( x ) measures 122° .

A company’s profit is described by the equation P ( x ) = − 5 x 2 300 x 15 , 000 , where x is the price in dollars that the company charges for its product. What should the company charge for the product to generate the maximum profit?.
the company should charge a price of $30 for its product to generate the maximum profit.To find the price that will generate the maximum profit, we need to find the vertex of the quadratic function P(x) = -5x^2 + 300x - 15,000.
The vertex of a quadratic function in the form ax^2 + bx + c is given by the x-coordinate of the vertex, which is -b/2a. In this case, a = -5 and b = 300.
x = -b/2a = -300 / (2 * -5) = 300 / 10 = 30.
Therefore, the company should charge a price of $30 for its product to generate the maximum profit.
It's worth noting that the profit equation provided is a simplified model and may not accurately represent the real-world dynamics of the company's profit. Additionally, other factors such as demand, competition, and production costs should also be considered in determining the optimal price for maximizing profit.

The measure of the length of x is equal to 225 rounded to the nearest whole number using the trigonometric ratios of tangent and sine
What are trigonometric ratiosThe trigonometric ratios involves the relationship of an angle of a right-angled triangle to ratios of two side lengths. Basic trigonometric ratios includes; sine cosine and tangent.
Considering the right triangle with opposite = 108 and adjacent = 81, the angle between them and hypotenuse is derived and used to solve for the base x of the entire right triangle as follows:
tan⁻¹(108/81) = 53.13°
hypotenuse side = √(108² + 81²)
hypotenuse side = √18225
hypotenuse side = 135.
For the entire right triangle;
the smaller angle = 180 - (90 + 53.13)
the smaller angle = 36.87
sin36.87 = 135/x
x = 135/sin36.87
x = 254.9995
Therefore, the measure of the length of x is equal to 225 rounded to the nearest whole number using the trigonometric ratios of tangent and sine

Answer:
397.7 m²
Step-by-step Explanation:
The are of ∆UVW can be found ones we know the measure of 1 angle that is in between known lengths of two sides. Then, we would apply the formula, ½*a*b*sin(θ)
Where, a and b, are the lengths having an included angle (θ), in between them.
To find area of ∆UVW, we need m < V, side lengths of UV and VW.
m < V = 113°
VW = 29 m
UV = ?
Step 1: find UV using the Law of sines
\( \frac{UV}{sin(W)} = \frac{VW}{sin(U)} \)
W = 34° [180 - (113+33)]
U = 33°
VW = 29 m
UV = ?
\( \frac{UV}{sin(34)} = \frac{29}{sin(33)} \)
Multiply both sides by sin(34)
\( \frac{UV*sin(34)}{sin(34)} = \frac{29*sin(34)}{sin(33)} \)
\( UV = \frac{29*sin(34)}{sin(33)} \)
\( UV = 29.8 m \)
Step 2: find the area of the triangle
Area = ½*a*b*sin(θ)
a = 29.8 m
b = 29 m
θ = 113°
Area = ½*29.8*29*sin(113)
Area = 397.7 m² (nearest tenth)

How to Convert Decimal to Octal?
Answer:
Step-by-step explanation:
We divide the number by 8 and write the remainder in reverse order to get the equivalent octal number.
Answer:
Let's write down the base of each one:
- Decimal is base 10 (0 to 9)
- Octal is base 8 (0 to 7)
So, if we want to convert decimal to octal, we need to divide the decimal number by 8 and hold onto the remainder.
Then once your quotient becomes 0, from the last remainder to the first, write your numbers.
For example here is 437 base 10.
437 / 8 = 54 R 5
54 / 8 = 6 R 6
6 / 8 = 0 R 6
So, the answer is 665 base 8.
