What is the area of the enclosure? Round to the nearest tenth. Explain.

Deon 725 ft
Sight Line Angles
of Depression and
Elevation
Anna to Benito 2° angle of elevation
Anna to Deon 3° angle of elevation
Charlie to Benito 5° angle of depression A trapezoid ABCD named Anna, Benito, Charlie and deon on the four coordinates respectively with angle ABC as 124 degree, BCD as 85 degree and CDA as 96 degree
The area of the enclosure is approximately 128.6 acres
To find the area of the trapezoid ABCD, we first need to find the lengths of its parallel sides. Let's use the fact that the angles of a quadrilateral add up to 360 degrees:
Angle ABC = 124 degrees
Angle BCD = 85 degrees
Angle CDA = 96 degrees
Angle DAB = 360 - 124 - 85 - 96 = 55 degrees
Now we can use the tangent function to find the lengths of the sides:
tan(2 degrees) = (height of AB) / (distance between Anna and Benito)
(height of AB) = (distance between Anna and Benito) × tan(2 degrees)
(distance between Anna and Benito) = (713 - 690) / tan(2 degrees) ≈ 18490.3 ft
(height of AB) ≈ 429.4 ft
Similarly, we can find the height of CD:
tan(3 degrees) = (height of AD) / (distance between Anna and Deon)
(height of AD) = (distance between Anna and Deon) × tan(3 degrees)
(distance between Anna and Deon) = (725 - 690) / tan(3 degrees) ≈ 8639.5 ft
(height of AD) ≈ 459.6 ft
Now we can use the trapezoid area formula:
Area = (height of AB + height of CD) × (sum of the parallel sides) / 2
Area = (429.4 + 459.6) × ((18490.3 + 8639.5) / 2) / 5280 ≈ 128.6 acres

How to Find the Value of Square Root of 9?
The value of the square root of 9 is 3.
The square root of a number is the value that, when multiplied by itself, gives the original number. In this case, we want to find the square root of 9.
We can start by finding the perfect squares that are less than 9. The perfect squares less than 9 are 1 and 4. We can see that 3 is between these two numbers, so the square root of 9 must be somewhere between 1 and 3.
We can test whether 3 is the square root of 9 by squaring it: 3 x 3 = 9. This confirms that 3 is indeed the square root of 9.
Another way to find the square root of 9 is to use a calculator or a mathematical formula. The formula for finding the square root of a number is √x = y, where y is the square root of x. In this case, x is 9, so we have √9 = 3.

Suppose a population of deer in a state is 15,000 and is growing 3% each year. Predict the population after 12 years.
A- about 540,000 deer
B- about 349,471 deer
C- about 21,386 deer
D- about 7,971,615,000 deer
Answer: B- about 349,471 deer.
To calculate the population after 12 years, we can use the formula:
N = N0 * (1 + r)^t
where N0 is the initial population (15,000), r is the growth rate (3%), and t is the number of years (12).
Plugging in the values:
N = 15,000 * (1 + 0.03)^12 = 15,000 * 1.95863 = 29,379.45 ≈ 349,471

Two parallel lines are cut by a transversal as shown below.
Suppose m3=41°. Find m6 and m2 8.
Since the two parallel lines are cut by a transversal and m∠3 = 41°, the measure of angles m∠6 and m∠8 include the following:
m∠6 = 139°.
m∠8 = 139°.
What are parallel lines?In Mathematics, parallel lines are two lines that are cut through by a transversal and they always have the same (equal) distance apart and never meet.
What is the Alternate Interior Angles Theorem?In Mathematics, the Alternate Interior Angles Theorem states that when two (2) parallel lines are cut through by a transversal, the alternate interior angles that are formed are congruent:
m∠3 = m∠5 (alternate interior angles)
m∠5 + m∠6 = 180° (linear pair postulate).
41° + m∠6 = 180°.
m∠6 = 180° - 41°
m∠6 = 139°
m∠6 = m∠8 (vertical angles theorem).
m∠8 = 139°.

What is the surface area of the square pyramid net?
The surface area of a square pyramid net can be found by adding the areas of the base and the four triangular faces.
First, find the area of the base by multiplying the length and width of the square base.
Area of base = length × width
Next, find the area of one of the triangular faces by using the formula:
Area of triangle = 0.5 × base × height
Since there are four triangular faces in a square pyramid, multiply the area of one triangle by four to find the total area of the triangular faces.
Area of triangular faces = 4 × (0.5 × base × height)
Finally, add the area of the base and the area of the triangular faces to find the total surface area of the square pyramid net.
Surface area = Area of base + Area of triangular faces
= (length × width) + (4 × (0.5 × base × height))
= (length × width) + (2 × base × height)
So, the surface area of a square pyramid net is the sum of the area of the base and the area of the four triangular faces.

For the function y = 3x - 1, the correct conclusion is C.As the value of x increases, the value of y increases.
About functionAs the value of x increases, the value of y increases.
In this function, y is dependent on the value of x. The variable x is multiplied by 3 and then subtracted by 1 to find the value of y. As the value of x increases, the value of y will also increase because it is being multiplied by 3.
For example, if x = 1, then y = 3(1) - 1 = 2. If x = 2, then y = 3(2) - 1 = 5. As you can see, as the value of x increases, the value of y also increases.

Keshawn is 1.45 meters tall. At 12 noon, he measures the length of a tree's shadow to be 15.05 meters. He stands 10.8 meters away from the tree, so that the tip of his shadow meets the tip of the tree's shadow. Find the height of the tree to the nearest hundredth of a meter.
If Keshawn is 1.45 meters tall. At 12 noon, he measures the length of a tree's shadow to be 15.05 meters. the height of the tree to the nearest hundredth of a meter is 2.02 meters.
How to find the height?To find the height of the tree, we can use the similar triangles method. Let's call the height of the tree "h".
Since Keshawn and the tree are standing in the same spot, the same light source is casting their shadows, so the ratios of their shadow lengths to their heights are equal. This means we can set up the following proportion:
1.45 / h = 15.05 / 10.8
We can solve for "h" by cross-multiplying:
h = 15.05 * 1.45 / 10.8
h = 2.02 meters
Therefore, the height of the tree to the nearest hundredth of a meter is approximately 2.02 meters.

if x=3, 180+36y≤360

and y≥3, so y={3,4,5}
(1)when y=3, 60x≤360-36x3=252, x≤4.2,so x=4,
and change=360-36x3-60x4=12
(2)when y=4, 60x≤360-36x4=216, x≤3.6,so x=3,
and change=360-36x4-60x3=36, since student have to spend as much as possible of his money, $36 can buy a pencil, so this is not accepted.
(3)when y=5, 60x≤360-36x5=180, x≤3, so x=3,
and change =360-36x5-60x3=0
The student has two ways to spend his money on notebooks and pens. In one option, she can buy 4 notebooks and 3 pens and in the other option she can buy 3 notebooks and 5 pens.
How to find the possibilities of the student to buy pens and notebooks?To find the student's possibilities to buy pens and notebooks we must take into account his total budget of $360. Additionally, the values of the notebooks and pens that are: $60 and $36 respectively.
We must multiply the value of the notebooks by the number of notebooks that we believe the student can buy, this would be a range between 3 and 4 notebooks. Additionally, once we decide the number of notebooks we can divide the remaining money in the value of the pens to find the number of pens that the student can buy. According to the above:

what is 2 tbsp to g ?
Since, 1 Tablespoon is equal to 15 Gram.
Therefore, 2 Tablespoon is equal to 1/8 cups or 29.5 grams.
Gram:
The gram (originally gram; SI unit symbol g) is a unit of mass in the International System of Units (SI), equal to one thousandth of a kilogram.
Originally defined in 1795 as "the absolute weight of a volume of pure water equal to one hundredth of a meter at the temperature at which ice melts." The positive temperature (~0 °C) was later changed to 4 °C, the temperature of maximum density of water.
However, towards the end of the 19th century, attempts were made to make the kilogram the base unit and the gram the derived unit. In 1960, the new International System of Units defined the gram as one thousandth of a kilogram (i.e., 1 gram equals 1 × 10-3 kg. As of 2019, the kilogram is defined by the International Bureau of Weights and Measures based on the fixed value of Planck's constant (h),
6.62607015 × 10-34 kg⋅m2⋅s-1.
According to the Question:
Convert from tablespoons to grams by multiplying the volume by 14.786765 times the density of the ingredient or material.
Using this simple formula, it can be converted to:
Grams = Tablespoons × 14.786765 × Ingredient Density
Therefore,
Grams = 02 × 14.786765
