Step-by-step explanation:
Define two ways of painting to be in the same class if one can be rotated to form the other.We can count the number of ways of painting for each specific class .
Case 1: Black-white color distribution is 0-6 (out of 6 total faces)
Trivially [tex]1^{2}[/tex]=1 way to paint the cubes.
Case 2: Black-white color distribution is 1-5
Trivially all [tex]\frac{6}{5}[/tex] =6 ways belong to the same class , so [tex]6^{2}[/tex] ways to paint the cubes.
Case 3: Black-white color distribution is 2-4
There are two classes for this case: the class where the two red faces are touching and the other class where the two red faces are on opposite faces. There are 3 members of the latter class since there are 3 unordered pairs of 2 opposite faces of a cube. Thus, there are [tex]\frac{6}{4}[/tex]-3=12 members of the former class . Thus, [tex]12^{2} + 3^{2}[/tex] ways to paint the cubes for this case.
Case 4: Black-white color distribution is 3-3
By simple intuition, there are also two classes for this case, the class where the three red faces meet at a single vertex, and the other class where the three red faces are in a "straight line" along the edges of the cube. Note that since there are 8 vertices in a cube, there are 8 members of the former class and [tex]\frac{6}{3} -8=12[/tex] members of the latter class. Thus, [tex]12^{2} - 8^{2}[/tex] ways to paint the cubes for this case.
Note that by symmetry (since we are only switching the colors), the number of ways to paint the cubes for black-white color distributions 4-2, 5-1, and 6-0 is 2-4, 1-5, and 0-6 (respectively).
Thus, our total answer is[tex]\frac{2*(6^{2} + 1^{2}+ 12^{2}+ 3^{2})+12^{2}+8^{2}}{2^{12} } =\frac{588}{4096} = \frac{147}{1024}[/tex]

the price p of a new house minus a 20% down payment
Answer:
0.8p or p - 0.2p
Step-by-step explanation:
You can find the price for any house minus the down payment by writing an expression with a variable. Let p be the price of the house. If you pay 20% then the price will be lowered by 20%. You will pay as your mortgage 80% of the price. You can write it as either the expression 0.8p or p - 0.2p.

Jorge worked 6 hours of overtime this week but has decided to take time off instead of overtime pay. How many hours will Jorge receive in time off from work
Jorge will receive 9 hours in time off from work.
How many hours will Jorge get to take time off?
It is given that, Jorge has done overtime for 6 hours in this week. As per the Fair Labor Standards Act, for 6 hours of overtime work, he must be paid one and a half times the pay he gets per hour.
Instead of receiving an overtime pay for working 6 hours extra, Jorge decides to receive paid leaves from work, that is, he will get one and a half of the total hours for which he worked overtime.
As a result, the time off he receives from work = [tex]1\frac{1}{2} (6)[/tex] hours
[tex]=\frac{3}{2}(6) = 9 hours[/tex]
Thus, Jorge gets 9 hours in time off from work in return. The time that he earns for the overtime is equivalent to the pay he was supposed to receive for the overtime work.

Answer: x = 15
Step-by-step explanation:
Hi!
These are supplementary angles, which means they both add up to 180°
Therefore,
9x+10 + 1x + 20 = 180
to solve, combine like terms
10x + 30 = 180
Then subtract 30 from both sides
10x = 150
now divide 10 from both sides leaving x by itself
x = 15

Answer:
I don't see a list of equations. See the attached image for an equation that works well.
Step-by-step explanation:
Someone please help me out
Answer:
A. y<-1/5x+1
Step-by-step explanation:
First, find the slope of the line
delta y / delta x = slope (delta means "change in", so delta y would the the change in y)
the change in y is 1, and the change in x is -5, so the slope is -1/5
we now know that the equation of the line is
y=-1/5x+1
The answer can't be c or d, because the line is dotted and not solid (solid lines signify ≥ or ≤, and dotted > and <)
To test if it is > or <, we can plug in some numbers to see if the equation is true
Right now, we have:
y[?]-1/5x+1, where "[?]" is either > or <
we see that the point 0,0 is a solution, since it is in the shaded region of the graph, because of this, we know that if we plug x=0 and y=0 into the equation, it must be true
plug in:
0[?]-(1/5)*0+1
0[?]1
clearly, [?] should be <, as 0<1
so, now that we know [?], we can replace it in our equation
y<-1/5x+1 , or "A"
At a certain fast-food restaurant, 56% of customers order a chicken sandwich, 43% of customers order french fries, and 30% of customers order both a chicken sandwich and french fries. What is the probability that a randomly selected customer will order a chicken sandwich or french fries (or both items)?
The probability that a randomly selected customer will order a chicken sandwich or french fries is 36%
How to determine the probability?
The given parameters are:
P(Chicken) = 56%
P(Sandwich) = 43%
P(Both) = 30%
The required probability is:
P = P(Chicken) + P(Sandwich) - P(Both)
This gives
P = 56% + 43% - 30%
Evaluate
P = 36%

32 less than 3/7 of a number is 11/35 of that number. Find the number.
Answer:
Step-by-step explanation:
Let "a number" be x.
"3/7 of a number" means (3/7)x
"32 less" means - 32
Thus, "32 less than 3/7 of a number" means (3/7)x -32
"is 11/35 of that number" means = (11/35)x
Put these together and we get:
(3/7)x -32 = (11/35)x
(3/7)x - (11/35)x = 32 Rearrang to get the x on one side
We need to change "(3/7)x - (11/35)" so that the two terms have a common denominator.
If we multiply the first term by (5/5) [which is equal to 1], we get:
(5/5)(3/7)x or
(15/35)x
We can now write:
(15/35)x - (11/35)x = 32
(4/35)x = 32
Multiply both sides by (35/4)
(35/4)(4/35)x = (35/4)(32)
x = (35)(8)
x = 280
Solve for p and k. For 50 POINTS!!
Answer:
P = 55°
K = 27°
Step-by-step explanation:
55° + 98° + c = 180°
153° + c = 180°
c = 27°
since C is opposite K, K = 27°
Since 55° is opposite P, P = 55°
We can check this by adding up the values of P, K, and 98
27°+55°+98° = 180°

A pencil cost $1.20 and a pen cost $2.90. Jasmiah bought an equal number of such pencils and pens. She spent $32.30 more on the pens than on the pencils. How many pencils and pens did she buy altogether?
Answer:
38
Step-by-step explanation:
Let x be the number of pencils bought.
Let y be the number of pens bought.
Given information from the question:
x = y - equation 1
2.9y - 1.2x = 32.30 - equation 2
From here we can use the substitution method in solving simultaneous equations to find x and y. We will substitute equation 1 into equation 2.
2.9y - 1.2y = 32.30
1.7y = 32.30
y = [tex]\frac{32.3}{1.7} \\= 19[/tex]
Now since we know number of pens = number of pencils,
x = 19
Total Pencils and Pens bought = x + y = 19 + 19 = 38

2. Given the equation of a line, y = 1/5x, the slope is:
Answer:
1/5
Step-by-step explanation:
The slope-intercept form looks like [tex]y=mx+b[/tex] where b is the y-intercept and m is the slope. m is the slope because if you increase x by 1, the value y increases by m, and if you increase x by 1 again, the y-value will increase by the value of m, because it's being multiplied. b is the y-intercept since the y-intercept is when x=0 so mx will become m(0) which is just 0 leaving b by it self. In this case you have y=1/5x so if you were to start with 0 as x the value of y is 0. Now increase it by 1 so x becomes 1, the value of y becomes 1/5x, now increase it by 1 again so x becomes 2, the value of y is 2/5x, so as you can see the function is just increasing by 1/5 so that's the slope, so essentially whatever the coefficient of x is (the number in front of the variable x), is the slope

Cαlligrαρɦγ136mm into cm and mm
Step-by-step explanation:
13.6 is the answer because 1cm is 10 cm
Answer:
13.6 cm
Is the second requested unit mm? The value is already in mm.
Step-by-step explanation:
Use conversion factors for the metric system.
By definition: 1cm = 10mm
We can write this as a conversion factor. Either:
1) 1cm/10mm, or
2) 10mm/1cm
We are given 136 mm. Convert that by using either conversion factor.
(136mm)*(1cm/10mm) = 13.6 cm Note how the mm unit cancels.
To use the other conversion factor, do a division:
(136mm)/(10mm/1cm) = 13.6 cm
====
136 mm is already 136 mm.

An inverse variation function has a k value of 8. Which ordered pair is on the graph of the function?
The points on the graph of the inverse variation are of the form:
(x, 8/x)
Which ordered pairs are on the graph of the function?An inverse variation function is written as:
y = k/x.
Here we know that k = 8.
y = 8/x
Then the points (x, y) on the graph of the function are of the form:
(x, 8/x).
So evaluating in different values of x, we can get different points on the graph:
if x = 1, the point is (1, 8)if x = 2, the point is (2, 4)if x = 3, the point is (3, 8/3)if x = 4, the point is (4, 2)And so on.
