Step-by-step explanation:
We can reach this conclusion after simulating the profit for each possible scenario made by The US weather service estimates:
For 80-day suitable weather per year:
total invested capital = $950,000 + $200,000 (total operating and maintaining cost) = $1,150,000per day revenue= 500 x $20 = $10,000total revenue per season = $10,000 x 80 days = $800,000total operating and maintaining cost = $2,500 x 80 = $200,000total profit (returns) in a season = $800,000-$200,000 = $600,000per year rate of return before taxes = 52% (total profit / total invested capital *100; $600,000/$1,1150,000 *100 = 52%For 100 days suitable weather per year:
total invested capital = $950,000 + $200,000 (total operating and maintaining cost) = $1,150,000per day revenue= 400 x $20 = $8,000total revenue per season = $8,000 x 100 days = $800,000total operating and maintaining cost = $2,500 x 100 = $250,000total profit (returns) in a season = $800,000-$250,000 = $550,000per year rate of return before taxes = 52% (total profit / total invested capital *100; $550,000/$1,1150,000 *100 = 47%For 120 days suitable weather per year:
total invested capital = $950,000 + $200,000 (total operating and maintaining cost) = $1,150,000per day revenue= 300 x $20 = $6,000total revenue per season = $6,000 x 120 days = $720,000total operating and maintaining cost = $2,500 x 120 = $300,000total profit (returns) in a season = $800,000-$250,000 = $420,000per year rate of return before taxes = 52% (total profit / total invested capital *100; $420,000/$1,1150,000 *100 = 58%Threfore, we notice that the 22% per year rate of return before taxes criteria was met in each of the possible scenarios, making the endeavor worthwhile.

items d

workers in a restricted
are n
area
a) solve for
When
do 30
I
b) solve for n
when
d=20
Answer:
a) we get value of n: n=10.7 or n=1.2 when d=30
b) we get value of n: n=9.6 or n=2.3 when d=20
Step-by-step explanation:
a) solve for n When do= 30
Put d= 30 in the given equation:
[tex]d = n^2-12n + 43[/tex]
[tex]30=n^2-12n+43\\n^2-12n+43-30=0\\n^2-12n+13=0\\[/tex]
Now, we will find value of n by using quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
We have a=1, b=-12 and c=13
[tex]n=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\n=\frac{-(-12)\pm\sqrt{(-12)^2-4(1)(13)}}{2(1)}\\n=\frac{12\pm\sqrt{144-52}}{2}\\n=\frac{12\pm\sqrt{92}}{2}\\n=\frac{12\pm9.59}{2}\\n=\frac{12+9.59}{2} , n=\frac{12-9.59}{2}\\n=10.7 , n=1.2\\[/tex]
So, we get value of n: n=10.7 or n=1.2
b) solve for n when d=20
[tex]d=n^2-12n+43\\20=n^2-12n+43\\n^2-12n+43-20=0\\n^2-12n+23=0\\[/tex]
Now, we will find value of n by using quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
We have a=1, b=-12 and c=23
[tex]n=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\n=\frac{-(-12)\pm\sqrt{(-12)^2-4(1)(23)}}{2(1)}\\n=\frac{12\pm\sqrt{144-92}}{2}\\n=\frac{12\pm\sqrt{52}}{2}\\n=\frac{12\pm7.21}{2}\\n=\frac{12+7.21}{2} , n=\frac{12-7.21}{2}\\n=9.6 , n=2.3\\[/tex]
So, we get value of n: n=9.6 or n=2.3
What is the relationship between the length of one leg and the length of the hypotenuse of an isosceles right triangles?
A) Leg = Hypotenuse ∙ √2
B) Hypotenuse = Leg ∙ √2
C) Leg ∙ Hypotenuse = √2
Answer:
B) Hypotenuse = Leg ∙ √2
Step-by-step explanation:
This is a well-known ratio in the 45-45-90 right triangle, but we can derive it.
An isosceles right triangle has two congruent legs forming the right angle and the hypotenuse opposite the right angle. The Pythagorean theorem works since it is a right angle.
Normally, the legs are a and b, and the hypotenuse is c, and we have
a^2 + b^2 = c^2
Here the legs are congruent, so we have a = b.
Substituting a for b, we have
a^2 + a^2 = c^2
2a^2 = c^2
c^2 = 2a^2
c = a√2
Answer: B) Hypotenuse = Leg ∙ √2
Answer:
progably B) Hypotenuse = Leg ∙ √2

Step-by-step explanation:
Answer:
5/9
Step-by-step explanation:
4/9 + 1/9
To add fractions, you need a common denominator. You already have a common denominator of 9, so just add the numerators.
4/9 + 1/9 = 5/9
Since there is no common factor of 5 and 9 other than 1, the fraction is already reduced.

The length of a rectangular piece of cardboard is 2 cm greater than its width. If the length and the width were each decreased by 1 cm, the area of the cardboard would be decreased by 27 cm². What are the dimensions of the original piece of cardboard?
Write and solve an equation to represent the problem.
9514 1404 393
Answer:
13 cm wide; 15 cm long
Step-by-step explanation:
Let w represent the original width. Then the original length is (w+2) and the original area is w(w+2). After the decrease, the width is (w-1) and the length is (w+1). The decreased area is (w-1)(w+1). The difference between these areas is 27, so we have ...
w(w+2) -(w-1)(w+1) = 27
w^2 +2w -(w^2 -1) = 27
2w +1 = 27
w = (27-1)/2 = 13
The original piece of cardboard was 13 cm wide and 15 cm long.

Answer:
x = 4Step-by-step explanation:
From the diagram, we can se that line l is parallel to m. This means that according to geometry, m<7 and m<9 are located on the same position on line n. Hence m<7 = m<9 (corresponding angle)
Given
m<7 = 9x+ 5
m<9 = x+37
Equaling both
9x + 5 = x+ 37
9x - x = 37-5
8x = 32
x = 32/8
x = 4
Hence the value of x is 4
48/8 = 42/x
Please select the best answer from the choices provided.
A: x = 42
B: x = 7
C: x = 8
D: x = 6
Answer:
D because 48 ÷ 8 = 6 42 +6 = 7
The best answer from the choices provided,
is x = 7.
The correct option is B.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
Given:
An expression,
48/8 = 42/x
Applying cross multiplication,
x = 42(8)/48
x = 7
Therefore, the value of x is 7.

Anthony is 154 cm tall, his brother Gerry is 5/7 as tall as him. How tall is Gerry?
:D can someone please help me with these problems please
The correct answer is 110 cm
Explanation:
Fractions always include two values (one at the top and the other at the bottom) and they represent the proportion of something, for example, 1/2 of an apple means there is only half apple. Now, to calculate how much is 5/7 of 154 centimeters, simply divide the total number into the denominator (bottom number) and then multiply the result by the numerator (top number). This process is shown in detail below:
[tex]\frac{5}{7}[/tex] - 5 is the numerator and 7 is the denominator
5/7 of 154 cm
154 cm / 7 = 22
22 x 5 = 110 cm

What is the volume of a prism?A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.
The volume of a prism is the product of its base area and height
Volume of Prism = B x h
where B = base area of prism
h = height of prism
Given data ,
Let the volume of the rectangular prism be represented as V
Now , the height of the prism is H = 4 units
The length and width of the prism is 1 and 16 units respectively
So , the base area of the prism B = 16 units²
Now , Volume of Prism = B x h
On simplifying , we get
The volume of rectangular prism V = 16 x 4
The volume of rectangular prism V = 64 units³
Hence , the volume of the rectangular prism is 64 units³

7x + y = 33
y=-7x+9
y=-7x-33
7y+y=-9
Answer:
y = -7x - 9Step-by-step explanation:
The standard from of equation of a line is expressed as;
y = mx+c
m is teh slope = -7
c is the intercept
Get the intercept by substituting m = -7 and the point (-2, 5) into the equation;
y = mx+c
5 = -7(-2) + c
5 = 14 + c
c = 5-14
c = -9
Substitute m = -7 and c = -9 into the expression y = mx+c
y = -7x - 9
Hence the required equation of the line is y = -7x - 9
