You need to create a fenced Off region of Land for cattle to graze. The grazing area must be a total of 500 square feet surrounded by a fence and in the shape of a regular polygon within this grazing area the length of the apothem must be 10 feet long.
Part. 1 find the total perimeter of the grazing area
Part 2. if the cost of the fence is $7.95 per linear foot how much will it cost to place a fence around the entire grazing area?
Part 3 - suppose this grazing area is 1/60 of an industrial grazing area for major industry farm. What is the total cost to build a fence around the entire land of the large scaled farm
Use property of proportions
show all work
Answer:
Part 1: The perimeter of total grazing area is 100 feet.
Part 2: The cost of fencing the entire grazing area is $759.
Part 3: The total cost to build a fence around the entire land of the large scaled farm is $ 45540.
A= perimeter X apothem /2
A=500
apothem = 10
500 = (P * 10)/2
P =100
B. 100*7.95 = $795
C.
60*100= 6,000
6,000 * $7.95=

I am a 2 dimensional shape that had 5 obtuse angles
Answer:
A pentagon.
Step-by-step explanation:
A pentagon is a 5-sided polygon. Its interior angles each are equivalent to 108°.
108° ≥ 90°, so the angles are obtuse.
Therefore, a 2-D shape with 5 obtuse angles is a pentagon.

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 27pie ft.
Which equation gives the volume of the sphere?
V=2/3(27pie)
V=4/3(27)
V=2/3(27)
V=4/3(27pie)
Description:
As we know that the sphere and the cylinder have the same radius and the height. Meaning
R = Radius
H = Height
V= 27 pie
Volume of the cylinder is 27 pie. We calculate the volume for the sphere and the cylinder which had the same radius and the height. And after that the answer will come. Meaning correct answer for this question is A.
Answer: V = 2/3 (27 pi)

Here is a rectangle.
4.3 cm
7 cm
7 cm
4.3 cm
The 6-sided shape is made from two of these rectangles.
Work out the perimeter of this 6-sided shap
Answer:36.6cm
Step-by-step explanation;
you can make a six sided shape by keeping the two rectangles as it makes the shape of L
perimeter = 2(4.3cm)+4(7cm)
=8.6cm=28cm
=36.6cm
The perimeter of the 6-sided shape assuming it jointly at 4.3 cm sides will be 36.6 cm.
What is the perimeter?Perimeter is the addition of an external measure of sides it will always positive.
A perimeter is a length and has a degree of the unit as one.
The perimeter of the circle = πd where d is the dia of the circle.
As per the drawn combined rectangle.
Perimeter = 2(4.3) + 4(7)
⇒ 36.6 cm
Hence "The perimeter of the 6-sided shape assuming it jointly at 4.3 cm sides will be 36.6 cm".

Which of the following are characteristics of the graph of the linear parent
function?
Check all that apply.
A. It is a straight line.
B. It is in quadrants II and IV.
C. It has a slope of 1.
D. It goes through the origin.
Answer: A,C, and D
Step-by-step explanation:
It is a straight line, it has a slope of 1 and it goes through the origin are the characteristics of the graph of the linear parent function
What is a function?A relation is a function if it has only One y-value for each x-value.
The linear parent function is the simplest form of a linear equation, which is y = x.
This equation has a slope of 1 and passes through the origin (0, 0).
The graph of y = x is a straight line that passes through the origin and extends infinitely in both directions.
Therefore, options A, C, and D are characteristics of the graph of the linear parent function.
Option B is not a characteristic of the linear parent function because it is not restricted to any specific quadrant; it passes through all four quadrants.
Hence, it is a straight line, it has a slope of 1 and it goes through the origin are the characteristics of the graph of the linear parent function

What is the slope, m, and the y-intercept of the line that is graphed below? On a coordinate plane, a line goes through points (negative 3, 0) and (0, 3). m = 1; (0, 3) m = 1; (–3, 0) m = –1; (0, 3) m = –1; (–3, 0)
Answer:
m = 1; (0, 3) is the correct answer.
Step-by-step explanation:
The general equation of a line is given by:
[tex]y=mx+c[/tex]
where, m is the slope of line
c is the y-intercept and
(x,y) are the points from where the line passes.
We are given that the line passes through 2 points (-3,0) and (0,3).
Putting the values of (x,y) in the equation of line.
Putting (0,3):
[tex]3 = m \times 0 + c\\\Rightarrow c =3[/tex]
So, y-intercept is (0,3).
Hence, equation of line becomes:
[tex]y = mx + 3[/tex]
Putting (-3,0) in [tex]y = mx + 3[/tex]:
[tex]0 = m(-3) +3\\\Rightarrow 3m = 3\\\Rightarrow m =1[/tex]
So, the equation of line becomes:
[tex]y = x +3[/tex]

m = 1; y intercept (0, 3) is the correct answer.

What is a reflection?A reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure.
The top left point will stay the same in the axis, and will be on the axis
Finally, the top right point will stay true same on the x-axis, but will be on the axis in its image.

What is the value of r in the equation -1.5(4-r)=-12?
–6
–4
4
6
Answer:
B -4
Step-by-step explanation:
-1.5(4 - r) = -12
Distribute -1.5.
-6 + 1.5r = -12
Add 6 to both sides.
1.5r = -6
Divide both sides by 1.5.
r = -4
Your answer is -4.
Answer:
r = -4
Step-by-step explanation:
-1.5(4-r)=-12
Divide each side by -1.5
-1.5 / -1.5 *(4-r)=-12 / -1.5
(4-r) =8
Subtract 4 from each side
4-r-4 = 8-4
-r = 4
Divide each side by -1
-r/-1 = 4/-1
r = -4

The population of a city is increasing at a rate of 4% each year. In 2000, there were 236,000 people in the city. Write an exponential growth function to model this situation. Then find the population in 2009.
Answer:
A = 236,000 (1+ 0.04)^9
335,902 people in 2009
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential growth function:
A = P (1 + r) t
Where:
p = original population (in 2000)
r = growing rate (decimal form) = 4/100 = 0.04
t= years
A = population after t years
Replacing with the values given:
A = 236,000 (1+ 0.04) ^t
To find the population in 2009:
We have to calculate the number of years passed since 2000: (2009-2000 = 9 years =t)
Substituting t=9 in the function:
A = 236,000 (1+ 0.04)^9
A =335,902 people
