How do we use the area of a polygon for Igloos?
Answer:
Igloos, Cones (such as ice cream cone), triangles ( such as roofs seen from one ... The tiles need to tessellate to cover an area without leaving any gaps .
Step-by-step explanation:
Any form of tiling involves polygons. The tiles need to tessellate to cover an area without leaving any gaps. This is directly connected to the angle properties of polygons.
Architects include polygons with every plan of a house - rooms usually have 90° corners, but not always. Rooms on a plan are polygons.
The cost of building any structure depends on the lengths of the walls and the size of the angles - all properties of polygons.
If a single free-standing room is to be built, the greatest ratio between the area and the perimeter is in a circle.
The smallest ratio between the area and the perimeter is found in a triangle. The best ratio in tessellating polygons is in a hexagon.
As soon as the cost of doing something one way as compared to another, it becomes a real life issue.
We are surrounded by polygons all the time.

An assembly line inspector inspected 340 machine parts. 323 of the parts passed inspection. What percent of the machine parts did NOT pass inspection?
Answer:
5% did not pass inspection
Step-by-step explanation:
Given
[tex]Inspected= 340[/tex]
[tex]Passed = 323[/tex]
Required
Determine the percentage of parts that didn't pass inspection.
First, we need to calculate the number of those that didn't pass inspection.
[tex]Failed = Inspected - Passed[/tex]
[tex]Failed = 340 - 323[/tex]
[tex]Failed = 17[/tex]
Next, we calculate the percentage as follows:
[tex]\% = \frac{Failed}{Inspected} * 100\%[/tex]
The above formula is derived by dividing the number of parts that didn't pass inspection by the total machine inspected, then multiplied by 100%
So:
[tex]\% = \frac{17}{340} * 100\%[/tex]
[tex]\% = \frac{17 * 100\%}{340}[/tex]
[tex]\% = \frac{1700\%}{340}[/tex]
[tex]\% = 5\%[/tex]
5% did not pass inspection
Given: tanA= -square root 15
What is the value of tan (A-pi/4)?
Answer:
D
Step-by-step explanation:
The value of tan (A-pi/4) is (-√(15)- 1) / 1 -√(15).
What is Tan(a - b) Identity in Trigonometry?One of the trigonometric identities for compound angles is the tan(a-b) identity. When the angle for which the tangent function value is to be determined is supplied in the form of the difference of any two angles, it is used. The compound angle is denoted by the angle (a-b) in the formula for tan(a-b).
Given:
tanA = -square root 15
tanA = -√(15)
To find the value of tan (A-pi/4):
Use the formula,
Tan(a - b) Identity
tan(A-B) = (tanA - tanB) / 1 + (tanAtanB)
Substituting the values,
tan(A-π/4) = (tanA - tanπ/4) / 1 + (tanAtanπ/4)
tan(A-π/4) = (-√(15)- 1) / 1 + (-√(15)
tan(A-π/4) = (-√(15)- 1) / 1 + (-√(15)
tan(A-π/4) = (-√(15)- 1) / 1 -√(15)
Therefore, the value is tan(A-π/4) = (-√(15)- 1) / 1 -√(15)

Hank owed a friend $2.00 then paid back the $2.00. Which of these describes how much Hank owes now?
Answer:
A
Step-by-step explanation:
If he borrows two dollars that looks like it should be +2 because he has 2 dollars that he didn't have before. But ...
The problem is that he now owes 2 dollars. So the two dollars that he borrowed is wiped out.
+ 2 for the two dollars - 2 when he pays it back. Result 0
+2 - 2 = 0
A
Answer:
I think it's A
Hank paid back the 2$ that he owned his friend so he no longer owes him more money so -2+2=0

Answer
418.2 m
Step-by-step explanation:
The first thing you need to realize to simplify the solving of this question for yourself is that since 5 cm are equal to 25 m, you can convert that into 1 cm is equal to 5 m. With that in mind, you then want to find the area of the rectangle in cm, which would be 6.8 times 12.3, which comes out to be 83.64. All you need to do from there is multiply that by 5, which should give you the answer of 418.2

2x - y = 3 and x+ y = 0
Answer:
I think this is it.....If not let me know
2x - y = 3
Slope = 2
x - intercept = 3/2 = 1.50000
y - intercept = 3/-1 = -3.0000
x + y = 0
Slope = -2.000/2.000 = -1.000
x - intercept = 0/1 = 0.0000
y - intercept = 0/1 = 0.0000

Complete the following:
1. Write an exponential expression: choose an odd number between 0 and 10 to be the base and an even number between 0 and 10 to be the exponent.
2. Label the base and the exponent.
3. Then write the exponential expression in expanded form and standard form
Answer:
[tex]e\frac{4}{3}[/tex] will be the exponential expression.
Step-by-step explanation:
We have to choose a number between 0 ad 10 and has to be odd to be base say 3
And even number between 0 ad 10 to be exponent say 4.
So the exponential expression will be : [tex]e\frac{4}{3}[/tex]

4/3x + 1/6x = 36 (solve for x please help I have no idea what it is!!!!!!!
Answer:
x = 24
Step-by-step explanation:
[tex]\frac{4}{3}[/tex]x + [tex]\frac{1}{6}[/tex]x = 36
Make the denominator the same by multiplying the first fraction by 2 to make both denominators 6.
[tex]\frac{8}{6}[/tex]x + [tex]\frac{1}{6}[/tex]x = 36
Now we can calculate the numerators and keep the denominators the same.
[tex]\frac{9}{6}[/tex]x = 36
Find x.
[tex]\frac{6}{6}[/tex]x = [tex]\frac{6}{9}[/tex] × 36

X=
Y=
Answer:
X=33 degrees
Y= 45
Step-by-step explanation:
The x would've been 90 degrees but the 57 degrees got in the way so if you subtract the 57 from 90 you get 33.
The y is if you look on the opposite side of the y there is a blank space that is the same exact size as the y size. So that would've been a 90 degrees as well but the other 90 degrees cut in the middle of it. Making you divide 90 in half.
If \triangle BTS\cong\triangle GHD△BTS≅△GHD, BS = 25, TS = 14, BT = 31, GD = 4x - 11, m\angle∠S = 56°, m\angle∠B = 21°, and m\angle∠H = (7y + 5)°, find the value of y.
Given:
△BTS≅△GHD, BS = 25, TS = 14, BT = 31, GD = 4x - 11, m∠S = 56°, m∠B = 21°, and m∠H = (7y + 5)°.
To find:
The value of y.
Solution:
In △BTS,
[tex]m\angle B+m\angle T+m\angle S=180^\circ[/tex] (Angle sum property)
[tex]21^\circ+m\angle T+56^\circ=180^\circ[/tex]
[tex]m\angle T+77^\circ=180^\circ[/tex]
[tex]m\angle T=180^\circ-77^\circ[/tex]
[tex]m\angle T=103^\circ[/tex]
We have,
[tex]\Delta BTS\cong \Delta GHD[/tex]
So, [tex]\angle T\cong \angle H[/tex] (By CPCTC)
Then, [tex]m\angle T=m\angle H[/tex]
Now,
[tex]103=7y+5[/tex]
[tex]103-5=7y[/tex]
[tex]98=7y[/tex]
Divide both sides by 7.
[tex]14=y[/tex]
Therefore, the value of y is 14.
