The area of the garden is 7 square feet.
Define area.The area a rectangle occupies is the space it takes up inside the limitations of its four sides. The dimensions of a rectangle determine its area. In essence, the area of a rectangle is equal to the sum of its length and breadth. An example of a quadrilateral with equal and parallel opposite sides is a rectangle. It is a polygon with four sides and four angles that are each 90 degrees. A rectangle is a shape with only two dimensions. A rectangle's area (A) is calculated by multiplying its length ('a') by its breadth ('b'). Area of Rectangle is therefore equal to (a× b) square units.
Given,
Width = 3/4
Length = 9 + 1/3
Length = 28/3
Area:
Length × Width
3/4 × 28/3

By applying the SSS similarity theorem, the value of x that will make the provided triangles similar is 77.
SSS Similarity Theorem: What is it?
The SSS similarity theorem is used to determine whether or not two triangles are similar.
The side-side-side, or SSS. According to this theorem, triangles are comparable if all three sides of one triangle are proportional to the three equivalent sides of another triangle.
The first triangle's sides in the example figure are 35, 20, and 20. The second triangle has sides x, 44, and 44.
So, according to the SSS similarity theorem,
x/35 = 44/20
x =44 *35 /20
x =77
By applying the SSS similarity theorem, the value of x that will make the provided triangles similar is 77.

the length length of a species of plants is normally distributed with expected value 60 cm. it is known from past experience that seventy five percent of theses flowers have length between 50 and 70 cm. what can we say about the standard deviation of the length of this plant?
The standard deviation of the length of this plant be 25.
m = 60(mean)
Let the standard deviation be s,
As, the probability for 50<x<70 be 0.75
Z = (x−m)/s
for x=50,
Z=0
for x=70,
Z=(70−50)/s=20/s
Now, the probability for 50<x<70 be,
P(50<x<70) = 0.75
In the standard form 0<z<(20/s)
using Z-table, the area from 0 to 20/s,

y≥x²+2x-8 factor the quadratic equation to find x intercepts
The factors of the quadratic equation are x≥-4, x≥2 and lies in the interval (-∞, -4]∪[2, ∞)
What is meant by quadratic equation?A quadratic equation is any equation that can be rearranged in standard form as ax²+bx+c=0 where x represents an unknown value and a, b, and c represent known numbers. In general, a = 0; equations with a = 0 are considered degenerate because the equation becomes linear or even simpler. The numbers a, b, and c are the equation's coefficients, and they can be distinguished by referring to them as the quadratic coefficient, linear coefficient, and constant or free term, respectively.
To find x-intercept y=0
y≥x²+2x-8
x²+2x-8≥0
x²+4x-2x-8≥0
x(x+4)-2(x+4)≥0
(x-2)(x+4)≥0

4.1.1. The two 3D objects in the figure are;
A triangular prismA rectangular prism4.1.2. The amount of wood needed is found by finding the surface area, A, of the dog kennel as follows;
A = 2×80×60+2×50×60+50×80+2×0.5×80×40+2×√(40²+40²)×50
A = 22800 + 80·√2×50 = 22800 + 4000·√2
The amount of wood needed = (22800 + 4000·√2) cm²
1 m² = 10,000 cm²
(22800 + 4000·√2) cm² = ((22800 + 4000·√2))/10,000 m²

The amount of wood needed is approximately 2.85 m²4.1.3. 500 milliliters of paint is enough to for 1.5 m² area
The number of containers of paint containers required, n, is therefore;
[tex]n = \dfrac{(2.28 + 0.4\cdot \sqrt{2}) \, m^2 }{1.5 \, m^2/container} = (1.52+0.\overline 6\cdot\sqrt{2} ) \, containers \approx 2 \, containers[/tex]

As stated, the population etiology fraction measures the disease rate in a population attributable to the exposure of interest. A measure that is primarily determined by the exposure caused by a particular disease. Therefore, it may be influenced by the relative risk of the disease in exposed individuals versus unexposed individuals, as well as the prevalence in the population of the exposure.
An epidemiological tool is the Population Attributable Risk, also called the Etiologic Fraction or Attributable Fraction. Efforts to eliminate a given risk factor would be expected to reduce the attributable risk to a specific percentage.

Same angle measures.Proportional side lengths.The second feature, the proportional side lengths, is what is used to find the missing measures, as proportional relationships are built according to them.
When two triangles are similar, the equivalent side lengths have to be identified for the two triangles, and those are the sides that have the same angle measures.
Then, for the two triangles, the equivalent sides will have proportional lengths, and then these equations will involve a missing length. Then cross multiplication is applied and the equation can be solved for the missing length.

In contrast, she requires 66 minutes to do 2 laps running and 10 laps walking. Assuming she maintains a consistent pace while running and while walking, how long does Leah take to complete a lap? Leah takes minutes to run a lap and minutes to walk a lap.
Using a system of equations, it is found that:
Leah takes 3 minutes to run a lap and 6 minutes to walk a lap.
What is the system of equations?The variables of the system of equations are presented as follows:
Variable x: time required to complete a lap running.Variable y: time required to complete a lap walking.She requires 84 minutes to do 8 laps running and 10 laps walking, hence the first equation is:
8x + 10y = 84.
She requires 66 minutes to do 2 laps running and 10 laps walking, hence the second equation is:
2x + 10y = 66.
Simplifying by 2, we have that:
x + 5y = 33.
x = 33 - 5y.
Replacing in the first equation, we can find the time it takes to walk a lap, as follows:
8(33 - 5y) + 10y = 84.
264 - 40y + 10y = 84
30y = 180
y = 180/30
y = 6 minutes.
Then the time it takes to run a lap is obtained as follows:
