For some time, Johannes Kepler thought that the Platonic solids were related to the orbits of the planets. He made models of each of the Platonic solids. He made a frame of each of the platonic solids by fashioning together wooden edges. How many wooden edges did Kepler have to make for the cube?
Kepler had 9 wooden edges to make for the cube.
As it is given in the data that the platonic solids are related to the orbits of the planets, and he made models of each of the Platonic solids. Kepler made a frame of each of the platonic solids by fashioning together wooden edges. At that time six planets were discovered and out of the six, two platonic solids were considered as cube. A cube is a three dimentional structure which has 8 corners and 12 edges.
So the number of edges = 4 x 2 + 1

Determine whether following set of numbers can be the measures of the sides of a triangle. If so, classify the triangle as acute, obtuse, or right. Justify your answer.
20,21,31
The following set of numbers, 20, 21 and 31, can be the measures of the sides of an obtuse triangle.
A triangle is a polygon with three sides and three vertices.
To know if a set of number is a valid measure of the sides of a triangle, it must follow the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.
let a = 20, b = 21, and c = 31
a + b > c 20 + 21 > 31 41 > 31 True
a + c > b 20 + 31 > 21 51 > 21 True
b + c > a 21 + 31 > 21 52 > 20 True
To know what type of triangle based on the length of its side:
1. Take the sum of the squares of the two smaller sides.
20^2 + 21^2 = 841
2. Compare it to the square of the largest side.
31^2 = 961
961 > 841
If the sum of the squares of the 2 is larger than the square of the 3rd, it is an acute triangle.
if they are equal, it is a right triangle
if they are smaller, then it is an obtuse triangle.
Hence, 20, 21 and 31 can be the measure of the sides of an obtuse triangle.

3/4x - 2/x²
The simplication of the given expression is (3x - 8) /4x² and the restriction on the variable in the denominator of the given expression is x ≠ 0.
According to the given question.
We have an expression 3/4x - 2/x^2
Since, we have to simplify the above expression.
Therefore,
3/4x - 2/x²
⇒ (3x - 8) /4x²
Hence, the simplication of the given expression is (3x - 8) /4x².
Also, we have to find the restriction on variable.
As we know that, we never divide by 0, a restriction on the variable of a rational function with a linear denominator would be any value of the variable that makes the linear denominator equals to 0.
So, for the restriction on the variable.
Set the denominator equals to 0.
⇒ 4x² = 0
Solve for x
x = 0 ( because 4 ≠ 0)
The denominator is 0 when x = 0. This is the only value that makes the given expression undefined.
Therefore, the restriction on the variable in the denominator of the given expression is x ≠ 0.

A rectangular mural measures 234 inches by 245 inches. rhianon creates a new mural that is 33 inches longer. what is the perimeter of rhianon's new mural?
The new mural created by Rhianon, which is 33 inches longer, has a perimeter of 1024 inches.
Perimeter refers to the total distance around a two-dimensional figure. The perimeter of a rectangle is the sum of all its 4 sides and is given by the formula
P = 2l + 2w
where l = length
w = width
If a rectangular mural measures 234 inches by 245 inches, length is usually longer than the width, and Rhianon creates a new mural that is 33 inches longer, then the length of Rhianon's mural is:
l = 245 inches + 33 inches
l = 278 inches
If the new mural is the same as the width of the rectangular mural and its length is 278 inches, then the perimeter can be solved using the formula for the perimeter of a rectangle.
P = 2l + 2w
P = 2(278 inches) + 2(234 inches)
P = 556 inches + 468 inches

Answer:
KN = 45, NM= 31, m<K = 61° m<L = 119°, m<M = 61°
Step-by-step explanation:
Given: KL = 31 LM = 45 N = 119°
This is a parallelogram so sides will equal.
KL = NM (31) LM = KN (45)
The inside of a parallelogram equals 360°. Opposite angles are congruent.
L = N (119°) So, 119 + 119 = 238
360 - 238 = 122
122 ÷ 2 = 61°
So, K = 61° M = 61° L = 119°

If x²- y² = 20 and x+y = 10, then find x
Answer:
x = 6
Step-by-step explanation:
x² - y² is a difference of squares and factors as (x + y)(x - y)
given
x² - y² = 20 , then
(x + y)(x - y) = 20 ← substitute x + y = 10
10(x - y) = 20 ( divide both sides by 10 )
x - y = 2 → (1)
x + y = 10 → (2)
add (1) and (2) term by term to eliminate y
2x + 0 = 12
2x = 12 ( divide both sides by 2 )

Jason is adding a climbing wall to his little brother's swing-set. If he starts building 5 feet out from the existing structure, and wants it to have a 60°C angle, how long should the wall be?
If Jason starts building 5 feet out from the existing structure, and wants it to have a 60° angle, then the wall should be 10 feet long.
For given question,
Jason starts building 5 feet out from the existing structure, and wants it to have a 60°C angle.
The ground and the side of the play structure make a 90° angle.
So, the given triangle would be a - 30°- 60° - 90° - triangle.
The short side is 5 feet. The climbing wall will be the hypotenuse.
The angle opposite to the short side is 5 feet.
Now we need to find the hypotenuse.
Consider the sine of angle 30°
sin(30°) = 5/hypotenuse
1/2 = 5/hypotenuse
hypotenuse = 5 × 2
hypotenuse = 10
Therefore, if Jason starts building 5 feet out from the existing structure, and wants it to have a 60° angle, then the wall should be 10 feet long.

If you throw a dart, what is the probability of
hitting the area of the shaded region?
Use 3.14 for T. Round answers to nearest Hundredth(two decimal places).
The probability of hitting the area of the shaded region is 0.21 (in the form of two decimal places) when you throw a dar.
What is probability?The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
We have been given that the radius of the circle = 2cm
So one side of square = 2+2 = 4cm
Area of circle = πr² = (3.14) ×(2)²= (3.14)×4 = 12.57cm²
Area of square = (a)² = (4)² =16cm²
Then the area of the shaded region = 16−12.57 = 3.43cm²
So the probability of hits in the shaded region = 3.43/16 = 0.2144
Round to the nearest Hundredth (two decimal places).
The probability of hits in the shaded region = 0.21
Hence, the probability of hitting the area of the shaded region is 0.21 (in the form of two decimal places) when you throw a dar.

Complimentary angles are those angles that sum up to 90 degrees
The supplement of the angle is 10° more than twice it's complement.
Therefore,
180 - x = 2(90 - x) + 10
open the brackets
180 - x = 2(90 - x) + 10
180 - x = 180 - 2x + 10
180 - 180 - 10 = -2x + x
