Rectangular plot:
To build a house, we are given a rectangular plot with length and façade dimensions. By law, there must be a minimum amount of space in front and back, as well as space on the other side.
Area can be defined as the amount of space covered by a plane of a particular shape. It is measured in "number" of square units (square centimeters, square inches, square feet, etc.). The area of a rectangle is the number of unit squares that fit in the rectangle. Examples of rectangles are flat surfaces such as laptop monitors, chalkboards, and painting canvases. We can use the rectangle area formula to find the space occupied by these objects. For example, consider a rectangle that is 4 inches long and 3 inches wide.
According to the Question:
To find the number of garden plots planted with peachy, just multiply them.

Answer:
A) (1, 1)--------------------------
Given system:
x - 2y = - 1,y = - 2x + 3.Solve by substitution:
x - 2(- 2x + 3) = - 1x + 4x - 6 = - 15x = 6 - 15x = 5x = 1Find y:
y = - 2*1 + 3 = - 2 + 3 = 1The matching choice is A.
Which of the following pair is a solution of the equation 2x - 3y = 7A(0,2)B(2, -3)C(5,1)D(1,5)
The pair in the solution of the equation 2x-3y = 7 is (5,1).
Solution of equationThe set of all values that, when substituted for unknowns, make an equation true is known as the solution.
Solution of linear equation in two variablesA specific location on the graph is the solution of a linear equation in two variables, where ax+by = c, meaning that when the x-coordinate is multiplied by a and the y-coordinate is multiplied by b, the sum of these two values equals c. There are essentially an endless number of solutions to a linear equation with two variables.
Now in the question,
To find the pair of solutions of equation 2x - 3y = 7, we satisfy all the pairs one by one in the given equation
1. Putting the value of (x, y) as (0,2) in the equation we get-
2*0 - 3*2 = 7 ⇒ -6 =7
Therefore LHS ≠ RHS
Hence it is not the solution to the equation.
2. Putting the value of (x, y) as (2,-3) in the equation we get-
2*2 - 3*-3 = 7 ⇒ 13 =7
Therefore LHS ≠ RHS
Hence it is not the solution to the equation.
3. Putting the value of (x, y) as (5,1) in the equation we get-
2*5 - 3*1 = 7 ⇒ 7 = 7
Therefore LHS = RHS
Hence it is the solution to the equation.
4. Putting the value of (x, y) as (1,5) in the equation we get-
2*1 - 3*5 = 7 ⇒ -13 =7
Therefore LHS ≠ RHS
Hence it is not the solution to the equation.
Thus (5,1) is the solution of the equation.

The probability of A or B would be 0.3269. Probability can be used to make predictions and make decisions based on uncertain information in fields such as finance, engineering, and science.
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, with 0 indicating that an event will not occur and 1 indicating that an event will definitely occur. Events with probabilities closer to 1 are considered more likely to happen, while events with probabilities closer to 0 are considered less likely.
Since A and B are mutually exclusive events, they cannot occur at the same time. Therefore, the probability of A or B is the sum of their individual probabilities.
p(A or B) = p(A) + p(B) = 0.07692 + 0.25 = 0.32692

Option G is the correct one. The table represents the non proportional linear relationship with equation y = 3x - 3.
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Linear equations may include one or more variables.
Given values are,
x = 4, then y = 9
x = 5, then y = 12
x = 2, then y = 3
This is clearly not a proportional relation since 4/9 ≠ 5/12
Let y = 3x - 3
If x = 4, then y = (3 × 4) - 3 = 9
If x = 5, then y = (3 × 5) - 3 = 12
If x = 2, then y = (3 × 2) - 3 = 3

There were 8 more small boxes shipped than large boxes and the total volume of all boxes was 245 cubic feet. Determine the number of small boxes shipped and the number of large boxes shipped.
Using equations, the number of small boxes shipped is 15 while the number of large boxes shipped is 7.
What is an equation?An equation is described as a mathematical statement of the equality of two or more mathematical expressions.
Equations use the equation sign (=) to show that the expressions are equivalent or equal.
The volume of each small box = 7 ft³
The volume of each large box = 20 ft³
The number of small boxes = x + 8
The number of large boxes = x
The total volume of all the boxes = 245 ft³
The total volume of the 8 additional small boxes = 56 ft³ (8 x 7 ft³)
The remaining volume of the boxes after subtracting the volume of the 8 additional small boxes = 189 ft³ (245 - 56)
Equations:7x + 56 + 20x = 245

In the given question, we have to find the volume of air in the spherical ball.
A sphere's capacity is measured by its volume. It is the area the sphere calls home. Cubic units are used to express the volume of a sphere. The sphere has a three-dimensional, rounded shape. Its shape is defined by its three axes, which are the x, y, and z axes.
Since the cross-section of the sphere is a circle, the volume in this situation is dependent on the radius's diameter. A sphere's surface area is the area or region of its outside. The following formula can be used to determine the volume of a sphere whose radius is "r":
V = [tex]\frac{4}{3}\pi r^{3}[/tex]
As given r = 3·10^2. So,
V = [tex]\frac{4}{3}\pi (3\cdot 10^2)^{3}[/tex]

What is Pythagorean theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.
The given triangle is a right- angles triangle.
Use the Pythagorean theorem to find the third side of the triangle.
The Pythagorean theorem is given by the following formula:
a^2 + b^2 = c^2
10^2 + b^2 = 26 ^2

The function represented by the table can be written as:
y = -4x + 3
How to find the function?Here we have a function represented by a table. Notice that for each increase of one unit in the x-value, the y-value decreases by 4.
Then we have a linear function, which can be written in a general form as:
y = a*x +b
Where a isthe slope and b is the y-intercept.
Because of the first pair on the table, (0, 3), we conclude that the y-intercept is 3, then we can rewrite:
y = a*x + 3
Now we can use the second point (1, - 1) and replace the values on the equation above.
