The distance is 295 feet from the surfers from his eyes.
What is geometry?Geometry is the description of figures in a space with a specific number of dimensions and types. Plane geometry is the most prevalent sort of geometry (dealing with objects like the point, lines, circles, triangles, and polygons),
According to the given question, we have attached a figure which represents the given situation.
Let the distance would be x from the surfers from his eyes
As per the figure, using the sine ratio to find x:
sin 29° = perpendicular/hypotenuse
Substitute the known values and solve for x:
sin 29° = 143/x
0.4848 = 143/x
x = 294.96
x ≈ 295 feet

The width of a rectangle 4n-9.5 feet and the length is 9.5n+10 feet. Find the perimeter of the rectangle
The perimeter of the rectangle is P = 27n + 1.
What is perimeter?The whole distance encircling a shape is referred to as its perimeter. It is the length of any two-dimensional geometric shape's boundary or outline. Depending on the size, the perimeter of several figures can be the same. Consider a triangle built of an L-length wire, for instance. If all the sides are the same length, the same wire can be used to create a square.
The length of the rectangle is: l = 9.5n+10.
The width of the rectangle is: w = 4n-9.5.
The perimeter of the rectangle is given as:
P = 2(l + w)
P = 2(9.5n + 10 + 4n-9.5)
P = 2(13.5n + 0.5)
P = 27n + 1
Hence, the perimeter of the rectangle is P = 27n + 1.

What is the percent increase of 24 to 32?
Answer:
8%???????????????????????
I will show you how calculate the Percent Change from 24 to 32.
Basically, we are trying to find the change from 24 to 32 in terms of percent. We do this in three steps:
1) Find the difference between 24 and 32 as a number.
2) Divide the result from Step 1 by the starting number 24.
3) Multiply the result from Step 2 by 100 to get it in terms of percent.
The three steps above can be made into a formula. So, to find the percent change from 24 to 32, we use this formula:
((Y-X)/X)*100 = Percent Change
X is the starting number 24, and Y is the ending number 32 that it changed to. When we enter these numbers into the formula, we get:
((32-24)/24)*100 = 33.33%
So, the answer to the question "What is the Percent Change from 24 to 32?" is:
33.33%
Note: All percent answers are rounded to the nearest two decimals if necessary.

The equation representing the hanger is 3x - 2y = 0 and when x = 6, y = 9
What is an equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, the weight of the square is y
And, the weight of the triangle is x
Now, the equation according to the diagram is;
x + 3y = 4x + y
4x - x + 3y - y = 0
3x - 2y = 0
Now, when, x = 6
So, y =
3x - 2y = 0
3x = 2y
3(6) = 2y
18 = 2y
y = 9
Hence, the equation representing the hanger is 3x - 2y = 0 and when x = 6, y = 9

What are the factors of x2 − 64? Prime (x − 4)(x 16) (x − 8)(x − 8) (x 8)(x − 8).
The factors of x^2 - 64 are (x - 8)(x + 8) because it follows the difference of squares formula, giving the correct factorization that yields x^2 - 64 when multiplied.
To factorize x^2 - 64, we can use the difference of squares formula, which states that a^2 - b^2 can be factored as (a - b)(a + b). In this case, a = x and b = 8. Applying the formula, we have (x - 8)(x + 8) as the factors of x^2 - 64. This is the correct factorization because when we multiply these factors, we get (x - 8)(x + 8) = x^2 - 64.
The other options provided (x - 4)(x + 16) and (x - 8)(x - 8) are not valid factorizations of x^2 - 64. The first option, (x - 4)(x + 16), does not yield x^2 - 64 when multiplied. The second option, (x - 8)(x - 8), is a repeated factor and does not represent the correct factorization. Therefore, the factors of x^2 - 64 are (x - 8)(x + 8).

Suppose that the function f(x)=5.32+0.80x represents the cost of mailing an
object that weighs x pounds. How much would it cost to mail an object that
weighs 35 pounds?
Answer:
$33.32
Step-by-step explanation:
f(x)=5.32+0.80(35)
=5.32+28
=$33.32
The required cost of mail of the object of 35 pounds is $33.32.
Given that,
f(x)=5.32+0.80x represents the cost of mailing an object that weighs x pounds.
To determine how much would it cost to mail an object that weighs 35 pounds.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
function f(x) represents the cost of mail of x weigh object,
Now for the x = 35
f(x) = 5.32 + 0.80 * 35
f(x) = 5.32 + 28
f(x) = 33.32
Thus, the required cost of mail of the object of 35 pounds is $33.32.

Take out D as well because the distance is around 2 - 2.66 units, and not under (Look at what I said previously).

In 1819, the United States purchased Florida from Spain for
$5 X 106. The area of Florida is about 6.6 x 104 square miles.
Which key strokes on a calculator will give the cost the
United States paid for each square mile of Florida?
Answer:
Option D. 5 EE 6 ÷ 6.6 EE 4
Step-by-step explanation:
Data obtained from the question include the following:
Area of land purchased = 6.6×10^4 square miles
Cost = $ 5×10^6
To determine the key strokes on a calculator which will give the cost the
United States paid for each square mile of Florida, let us calculate cost of 1 square mile.
This can be obtained as follow:
6.6×10^4 sq mile = $ 5×10^6
Therefore,
1 sq mile = $ 5×10^6 ÷ 6.6×10^4
In calculator, the key strokes will be:
5 EE 6 ÷ 6.6 EE 4
Answer:
Like Eduard22sly said D). 5 EE 6 ÷ 6.6 EE 4 is correct.

There are 5 positions available in the new school. Of the applicant, 12 are men and 8 are women. In how many ways can 3 men and 2 women be chosen if they are equally considered?
There are 3080 ways 3 men and 2 women can be chosen if they are equally considered, using the multiplication principle of counting
What is the multiplication principle of countingThe multiplication principle states that if there are m ways to perform one task and n ways to perform another task, then there are m x n ways to perform both tasks together.
To find the number of ways to choose 3 men from the 12 men, we can use the formula for combination, which is: ⁿCᵣ = n! / (r! (n-r)!).
where n is the total number of men and r is the number of men chosen
so, the number of ways to choose 3 men from the 12 men = ¹²C₃ = 1.
Similarly, we evaluate the number of ways to choose 2 women from the 8 women
as = ⁸C₂ = 14
Now, using the multiplication principle, we can find the total number of ways 3 men and 2 women be chosen if they are equally considered.
220 x 14 = 3080
Therefore, there are 3080 ways 3 men and 2 women can be chosen if they are equally considered, using the multiplication principle of counting

What is the Inequality of the Graph?From the given graph, we have the following points coordinates;
(x1, y1) = (2, 5)
(x2, y2) = (6, 13)
The formula to calculate the slope is;
m = (y2 - y1)/(x2 - x1)
Thus;
m = (13 - 5)/(6 - 2)
m = 8/4
m = 2
On the graph, we have the following observations:
The line of the graph is a dashed line (this represents > or <)

There are 5 full square and 6 triangles that are half squares.
5 + (6)(1/2) = 5 + 3 = 8
You could also break this into smaller shapes (like a big triangle on the top and a smaller triangle and rectangle on the bottom and use area formulas to calculate the area. But counting works well in this example.
Answer: 8
Step-by-step explanation:
First you split up this shape into two different shapes, a triangle and trapezoid
Put a line through the coordinates (-2,2) to (-1,2); the top is a triangle and the other is a trapezoid
Area of the trapezoid is A = .5x (base1 + base2) x height
base1 of the trapezoid goes from -4 to -1 which is 3
base2 goes from -2 to -1 which is 1
height is 0 to 2 whcich is 2
A = .5 x (3+1) x 2 = 4
Now area of a triangle is A = .5 x base x height
the base goes from -2 to 2 which is 4
the height goes from 2 to 4 which is 2
A = .5 x (4) x (2) = 4
Area of the Trapezoid + Area of the Triangle = Total Area
4 + 4 = 8
