“The length of a rectangle is two feet greater than twice its width. If the perimeter is 25 feet, find the width.” Which of the following translations is correct?
Answer:
b is the answer
Step-by-step explanation:
Student Council members are designing a large poster that will tell people who each member is and what position each person holds. Each member gets a triangle piece of paper to decorate, then all the pieces will be fitted together to form the final display. The triangles are identical and fit together to form a regular polygon. It will look similar to the shape below:
A) If there are 8 council members, what type of polygon will be formed?
B) To achieve this shape, what type of triangles will the individual pieces be? What will be the measures of each of the three angles in each of the triangles?
C) What will be the sum of the measures of the internal angles of the final shape?
D) Redo parts (b) and (c) if the Council decides to include triangles for the two staff advisors, assuming the poster will still form a regular polygon, but now with 10 triangles.
A) With 8 council members, the polygon formed with the triangles will be an octagon.
A polygon formed with a set of isosceles triangles will have as many sides as triangles you are using. An octagon is a geometric figure that has 8 equal sides to it.The final shape should look just like the one you posted with your question.
B) The individual pieces should be isosceles triangles. The three angles of each triangle should measure 45°, 67.5° and 67.5°.
An isosceles triangle is the one that has two sides of the same length and one side with a different length.We need two sides of the triangles to be the same. The base of the triangle's length will depend on the number of triangles we are using to form the final polygon.
The number of triangles will define the angle between the two sides of equal length. You can find this by dividing 360° into the number of triangles:
[tex]\frac{360^{o}}{8}=45^{o}[/tex]
The other two angles should measure the same, so we can find them by subtracting the 45° from 180° (which is what we get when adding the three angles of any triangle) and then dividing the answer into 2.
180°-45°=135°
[tex]\frac{135^{o}}{2}=67.5^{o}[/tex]
C) The sum of the measures of the internal angles of the final shape should add up to 360°, that way we can guarantee that the figure is closed:
45°+45°+45°+45°+45°+45°+45°+45°=360°
D)
D.B) The individual pieces should be isosceles triangles. The three angles of each triangle should measure 36°, 72° and 72°.
The number of triangles will define the angle between the two sides of equal length. You can find this by dividing 360° into the number of triangles:
[tex]\frac{360^{o}}{10}=36^{o}[/tex]
The other two angles should measure the same, so we can find them by subtracting the 36° from 180° (which is what we get when adding the three angles of any triangle) and then dividing the answer into 2.
180°-36°=144°
[tex]\frac{144^{o}}{2}=72^{o}[/tex]
C) The sum of the measures of the internal angles of the final shape should add up to 360°, that way we can guarantee that the figure is closed:
36°+36°+36°+36°+36°+36°+36°+36°+36°+36°=360°

home over time.
(b) At this rate, determine the date of the resale price of the home would reach $1 million (Show your
work to accurate to the nearest month)
(c) Use your exponential equation to determine the expected resale value of the home on April 1, 2020.
Answer:
The right answer is:
(a) [tex]P(t) = P_o \ e^{0.03536t}[/tex]
(b) [tex]t = 14 \ years \ 6 \ months[/tex]
(c) [tex]P(t) = =621,595.6[/tex] ($)
Step-by-step explanation:
Given:
House price increment rate,
= 3.6% annually
(a)
Let the exponential equation will be:
⇒ [tex]P(t) = P_o e^{Kt}[/tex]
here,
t = 0
P = P₀
t = 1 yr
then,
[tex]P(1) = P_o +3.6 \ persent \ P_o[/tex]
[tex]=1.036 \ P_o[/tex]
now,
⇒ [tex]1.036 P_o = P_o \ e^{K.1}[/tex]
[tex]ln(1.036) = K[/tex]
[tex]K = 0.03536[/tex]
Thus, the exponential equation will be "[tex]P(t) = P_o \ e^{0.03536t}[/tex]".
(b)
We know,
[tex]P_o = 600,000[/tex] ($)
[tex]P(t) = 10,00,000[/tex] ($)
∵ [tex]P(t) = P_o \ e^{0.03536t}[/tex]
[tex]1000000=600000 \ e^{0.03536 t}[/tex]
[tex]\frac{5}{3}= e^{0.03536 t}[/tex]
[tex]ln(\frac{5}{3} )=0.03536 t[/tex]
[tex]\frac{\frac{0.5}{0825} }{0.03536} =t[/tex]
[tex]t = 14.45 \ years[/tex]

The table that shows the relationship of the total number of pieces of fruit to the number of bananas.
To find:
Why is [tex]\dfrac{6}{5}[/tex] not equivalent to [tex]\dfrac{3}{2}[/tex].
Solution:
If a, b, c are real numbers, then
[tex]\dfrac{a}{b}=\dfrac{a\times c}{b\times c}[/tex]
The given fraction is [tex]\dfrac{3}{2}[/tex]. It can be written as:

Identify the equation of the circle that has its center at (9, 12) and passes through the origin.
Answer:
(x-9)^2 +(y-12)^2 = 225
Step-by-step explanation:
First find the length of the radius
If is the distance from the center to the point
d = sqrt( (x2-x1)^2 + (y2-y1)^2 )
= sqrt( (0-9)^2 + (0-12)^2)
= sqrt ( 81+144)
= sqrt(225)

Answer:
x = 40
y= 20
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 60 = 20 sqrt(3)/ x
x sin 60 = 20 sqrt(3)
x = 20 sqrt(3)/ sin 60
x = 20 sqrt(3)/ sqrt(3)/2
x = 20 *2
x = 40
tan theta = opp /adj
tan 60 = 20 sqrt(3)/y
y = 20 sqrt(3)/ tan 60
y = 20 sqrt(3) / sqrt(3)
y = 20

Any point on the circle must be at a distance from the center equal to the length of the circle’s radius. In this example, the radius is 3.61 units, AC = 4.24, and AD = 3.61. Point D, which lies on the circle, has the same distance from the center as the length of the radius. Point C, which lies outside the circle, is at a different distance from the center than the length of the radius.

the system of equations y =-3x+2 and y =1/2 x -6 is shown on the graph below. What is a reasonable estimate for the solution>
The reasonable estimate for the solution is (2.29, -4.87)
The reasonable estimate for the solution is the point where the two lines intersect each other.
To get the point where they intersect, we will simply equate the system of equations given as shown:
[tex]-3x+2=\frac{1}{2}x-6\\Collect \ the \ like \ terms\\-3x-\frac{1}{2}x=-6-2\\\frac{-7x}{2}=-8\\-7x=-16\\x=\frac{16}{7} \\x=2.29[/tex]
Substitute x = 2.29 into any of the equation
Using the equation y = -3x+2
y = -3(2.29)+2
y = -6.87+2
y =-4.87
This shows that the reasonable estimate for the solution is (2.29, -4.87)

The point of intersection of the linear equations is approximately [tex](x,y) = (2.286, -4.857)[/tex].
The most quickest approach that offers a reasonable solution consist in representing both linear functions graphically by means of a graphing tool (i.e. Desmos). As there is a system of two equation and two variables, the system can be represented by 2D-graphing tool.
The solution of this system is represented by the point, in which both lines intercepts each other. Let be the following two linear functions:

Answer:
108 degrees
Step-by-step explanation:
an arithmetic progression means that there is a constant inbetween all of the angles. Since the smallest angle is 12 degrees, ( i just guessed and checked) and came up with the angles :
12, 60, 108
these have a constant of 48
Answer:
108°
Step-by-step explanation:
Since the angles are in arithmetic progression , then the angles are
a + a + d + a + 2d
a is the first term and d the common difference
Sum the angles and equate to 180 with a = 12
a + a + d + a + 2d = 180
12 + 12 + d + 12 + 2d = 180 , that is
36 + 3d = 180 ( subtract 36 from both sides )
3d = 144 ( divide both sides by 3 )
d = 48
Then the largest angle is
a + 2d = 12 + 2(48) = 12 + 96 = 108°
