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 edges did Kepler have to make for the cube?
In order to construct frames for each of the platonic solids, Kepler has to construct nine wooden edges for the cube. These edges will then be pieced together to make the frames.
The Edges of Kepler:He created models of each of the platonic solids since it is shown in the data that they are connected to the planets' orbits. Kepler fashioned wooden edges to form each of the platonic solids into a frame.
Two of the six planets identified at the time were regarded to be platonic solid cubes. The three-dimensional shape of a cube has 12 edges and 8 corners.
Thus, there are 4 x 2 + 1 edges.
= 9
Kepler must create nine wooden edges for the cube in order to piece together wooden edges to form frames for each of the platonic solids.

Use Distributive Property:
(x+3)(x+5)
[tex]x^{2}+5x+3x+15[/tex]
[tex]x^{2} +8x+15[/tex] Answer
Answer: x ^ 2 + 8x + 15
Step-by-step explanation: You can use the FOIL method to multiply. F - first two variables, so the two x.
x • x = x^2
O - outside, the outermost variables in the parenthesis, which would be x and 5.
x • 5 = 5x
I - inside, the innermost variables in the parenthesis, which would be x and 3.
x • 3 = 3x
L - last two variables, so 3 and 5.
3 • 5 = 15
Altogether:
x^2 + 5x + 3x + 15, which simplifies to x^2 + 8x + 15.

Explanation:
We want to write a percentage that is between 3/4 and 7/9.
First, begin by converting each of the fractions to its decimal equivalent.
[tex]\begin{gathered} \frac{3}{4}=0.75 \\ \frac{7}{9}\approx0.78 \end{gathered}[/tex]Thus, we can say that:
[tex]\begin{gathered} 0.75<0.76<0.78 \\ 0.76=0.76\times100=76\% \end{gathered}[/tex]A percentage that is in between 3/4 and 7/9 is 76%.
Find the equation of the line passing
through the points (4, 2) and (6, 10).
y=[?]x+[ ]
Answer:
y = 4x - 14
Step-by-step explanation:
The equation of a straight line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).
We can calculate the slope with the two given points. Slope is the Rise/Run between these 2 points:
(4,2) and (6,10)
Rise: 10 - 2 = 8
Run: 6 - 4 = 2
Slope = Rise/Run = 8/2 = 4
m is 4, so we can write: y = 4x + b
We can find b by entering either of the given points and solving for b. I'll use (4,2):
y = 4x + b
2 = 4*(4) + b
2 = 16 + b
b = -14
The equation becomes y = 4x - 14

Trevor makes some flapjacks using this recipe and uses 200g of syrup. What quantity of butter should he use
Answer:
The quantity of butter that was used will be 100g.The total quantity of flapjacks that was made will be 450g.Step-by-step explanation:
How to illustrate the information?It should be noted that the ratio of syrup, sugar, butter and oats was illustrated as:
1:2:3
Therefore, when 50g of syrup was used, the quantity of butter that was used will be:
= 50 × 2 = 100g
The rural quantity of flapjacks that was made will be:

John cashed a check for $630. The teller gave him three 50-dollar bills, eighteen 20-dollar bills, and t 10-dollar bills. Determine the value of t.
$630
The value of t is $12.
Solution:
3 x 50 = 150
18 x 20 = 360
The sum is 360 + 150 = 510. Then subtract the value 510 from 630.
$630 - 510
$120
120 / 10 = 12
Subtract the null hypothesis mean from the sample mean. Divide the difference by the sample standard deviation. Multiply the result by the square root of the sample size. The t value measures the magnitude of the difference relative to the variability of the sample data. In other words, T is simply the calculated difference expressed in units of standard error.
The larger the size of T the more evidence against the null hypothesis. The important t-value is the limit of the t-distribution. The t distribution is a probability distribution used to compute population parameters when the sample size is small and the population variance is unknown. The T-score is used to analyze whether to support or reject the null hypothesis.

( 5x + 3 )( 4x - 5 ) is the factorized form of the polynomial 20x² - 13x - 15 using the AC method.
How to factor a polynomial?AC Method is simply a method of factoring trinomials in the form ax² + bx + c.
Given the polynomial in the question;
20x² - 13x - 15
Compare to the form ax² + bx + c
a = 20b = -13c = -15To factor, compare to the form ax² + bx + c and rewrite the middle term as a sum of two terms whose product is;
a × c = 20 × -15 = -300
and whose sum is;
b = -13
Now, factor -13 and of -13x
20x² - 13(x) - 15
We know that -13 is the same as 12 - 25
20x² + (12 - 25)(x) - 15
20x² + (12 - 25)x - 15
Apply distributive property
20x² + 12x - 25x - 15
Group the terms
(20x² + 12x) - 25x - 15
Now, factor out the greatest common factor from each group
4x( 5x + 3 ) - 5( 5x + 3 )

In the figure below, m < 1 = (x + 14) and m < 2 = 3x
Find the angle measures.
The angle measures are;
m < 1 = 33°
m < 2 = 57°
How to determine the anglesIt is important to note that complementary angles are defined as pairs of angles that sum up to 90 degrees.
From the information given, we have the angle measures as;
m < 1 = (x + 14) m < 2 = 3xThis can be represented as;
m < 1 + m < 2 = 90
Now, let's substitute the values into the equation, we have;
(x + 14) + 3x = 90
expand the bracket, we have;
x + 14 + 3x = 90
collect like terms
4x = 90 - 14
subtract the values
4x = 76
Make 'x' the subject of formula, we get;
x = 76/4
x = 19
Then,
m < 1 = (x + 14) = 19 + 14 = 33°
m < 2 = 3x = 3(19) = 57°

To convert miles per hour to feet per second, which conversion factor would not be used?
To convert miles per hour to feet per second the conversion factor that wouldn't be used is option d: 1 mi/5280 ft and 5 miles per hour will be equal to 7.34 feet per seconds.
As per the question statement, we are asked that which of the given conversion factors, will not be used for converting miles per hour to feet per second.
We should be knowing the following values for conversion:
we know, 1 mile = 1.6 km = 5280 feet
and 1 hour = 60 minutes = 3600 seconds.
Now, mi/hr * 1hr/60min * 1min/60sec * 5280ft/mi
Note that units all cancel out leaving only ft/sec
Hence option d : 1 mi/5280 ft is not appropriate for converting mi/hr to ft/sec.
For e.g., 5 miles per hour = 5*5280/3600
5 mil/hr = 7.34 ft/sec
Hence, to convert miles per hour to feet per second the conversion factor that wouldn't be used is option d: 1 mi/5280 ft and 5 miles per hour will be equal to 7.34 feet per seconds.

burns 350 calories an hour, and by walking, which burns 200 calories an
hour. If Karl has 10 hours per week to devote to exercise, determine the
combination of walking and cycling that will allow him to achieve his goal
of burning exactly 3000 calories.
Karl must cycle for seven hours and stroll for three hours each week in order to burn precisely 3000 calories.
How is the combination of walking and strolling calculated for burning exactly 3000 calories?Given:
No. of calories to burn by Karl = 3000
No. of calories burnt per hour by walking = 200
No. of calories burnt per hour by cycling = 350
No. of hours per week for Karl = 10
To find: No. of hours required to exercise through walking and cycling for burning 3000 calories.
Let W be the no. of hours required to burn calories in one hour by walking.
Let C be the no. of hours required to burn calories in one hour by cycling.
Formulating the given information
W+C = 10 ⇒ (1)
200W + 350C = 3000
Multiplying equation (1) by 200
200W + 200C = 2000
Subtracting equation (3) from equation (2)
150C = 1000
C ≈ 7
Substituting in equation (1)
W + C = 10
W + 7 = 10
W = 3
Therefore W = 3 and C = 7

The equation of the parallel line is
(Use integers or fractions for any numbers in the equation. Simplify your answer.)
Answer:
Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.
Parallel lines have the same gradient so gradient of line is -3.
Equation of line is y = -3x + c.
Substitute C(2,7) into the equation to find c.
7 = -3(2) + c
c = 13
Hence, equation of line is y = -3x + 13.
