The number of ways in which 6 pictures can be hung from 8 picture nails on the wall is b) 20160.
Given:
The number of ways in which 6 pictures can be hung from 8 picture.
Number of ways = [tex]8_C_{6}[/tex]*6!
[tex]8_C_{6}[/tex] = 8!/(8-6)!6!
= 8!/2!*6!
= 8*7*6! / 2*1*6!
= 56/2
= 28
6! = 6*5*4*3*2*1
= 30*4*3*2*1
= 120*3*2*1
= 360*2*1
= 720*1
= 720
[tex]8_C_{6}[/tex]*6! = 28*720

Consider the following equation:
3|x+3|−12=0
Step 2 of 4: Using the definition of absolute values, convert the standard form of the given equation into two equations without absolute value signs.
The value of x in the following equation: 3|x+3|−12=0 is -7 and 1
The equation is 3|x+3|−12=0
The modulus function can be positive and negative
Considering it to be negative,
the equation is
3((-1)(x + 3) - 12
3(-x - 3) - 12
-3x - 9 - 12 = 0
3x + 21 = 0
3x = -21
x = -7
3(x + 3) - 12
3x + 9 - 12
3x - 3 = 0
3x = 3
x = 1
Therefore, the value of x in the following equation: 3|x+3|−12=0 is -7 and 1

h(t)= t+ 1/t^2+2t+2.
Find derivative.
The derivative of given function is H’(t) = 3 – 2/t3
A derivative is a two-party contract whose value/price is derived from an underlying asset. Futures, options, forwards, and swaps are the most prevalent types
Given that H(t)= t+ 1/t^2+2t+2
We must calculate the derivative
H(t)= t+ 1/t^2+2t+2
H(t) = 3t + 1/t^2 + 2
H’(t) = d/dt(3t + 1/t^2 + 2)
H’(t) = d/dt(3t) + d/dt (1/t^2) + d/dt ( 2)
H’(t) = 3xd/dt(t) + d/dt (1/t^2) + d/dt ( 2)
H’(t) = 3xd/dt(t) + d/dt (t-2) + d/dt ( 2)
H’(t) = 3 – 2t-3
H’(t) = 3 – 2/t3
Therefore the derivative of the given function is H’(t) = 3 – 2/t3

What is a piecewise-defined function?A piecewise-defined function is a function that has different definitions, depending on the input of the function.
In this problem, the function given by the first graph has two definitions, as follows:
To the left of x = 0.To the right of x = 0.The two functions are linear with intercept 0, hence the definitions are given as follows:
x < 0: y = 2x, as when x increases by 1, y increases by 2, hence slope of 2.x > 0: y = -0.5x, as when x increases by 2, y decreases by 1, hence slope of -0.5.After the transformation x -> 0.5x, the definitions are given as follows:

Solve the equation: u^6 − 49 u^4 = 0 .
The given equation solved for u is u = 7 or u = -7
Solving an equationFrom the question, we are to solve the given equation.
The given equation is
u^6 − 49 u^4 = 0
First, we will write the equation properly
The given equation written properly is
u⁶ - 49u⁴ = 0
Now,
To solve the equation, we will determine the value(s) of the variable. The variable in the given equation is u.
Thus,
We will solve for u
u⁶ - 49u⁴ = 0
Add 49u⁴ to both sides of the equation
u⁶ = 49u⁴
Divide both sides by u⁴
u⁶/u⁴ = 49u⁴/u⁴
u² = 49
Then,
u²- 49 = 0
u² - 7² = 0
Factorize by applying the rule for difference of two squares
(u + 7)(u - 7) = 0
Then,
u + 7 = 0 OR u - 7 = 0
u = -7 OR u = 7
Hence, the value of u is -7 OR 7

For the given measures of angles of heptagon, the value of x is equal to 27° .
As given in the question,
Sum of all the interior angles of the heptagon is equal to 900.
Given measure of all the angles of the heptagon is given by :
135°+( 5x - 4 )° +( 7x - 64 )° + 120° +( 6x - 8 )° +( 4x + 15 )° + ( 3x + 31 )°= 900°
Arrange all the like terms of the given expression together we get,
⇒ ( 5x + 7x + 6x + 4x + 3x )° + ( 135 - 4 - 64 + 120 - 8 + 15 + 31 )° = 900°
⇒ 25x° + 225° = 900°
⇒ 25x° = 900° -225°
⇒ 25x° = 675°
⇒ x = 27°
Therefore, for the given measures of angles of heptagon, the value of x is equal to 27° .

Brooklyn scored 27 points in the basketball game. That was 12 points more than her friend, Cienna, scored. How many points did they score altogether? * 2 points
Answer:
42 points
Step-by-step explanation:
If Brooke scored 27 points, 12 less than that would be what Cienna scored. To find this, you would do 27 - 12. This is equal to 15, so Cienna scored 15 points.
To find how much they scored together, you would add both their scores. Brooke scored 27 and Cienna scored 15, so 27 + 15 = 42. Therefore, they scored 42 points together.

Almond Bark
Weight (ounces) 2 6 14
Cost (dollars) 3 9 21
Determine how much more one candy costs per ounce than the other candy.
Peanut brittle costs $0.50 more per ounce than almond bark.
Almond bark costs $0.50 more per ounce than peanut brittle.
Peanut brittle costs $0.33 more per ounce than almond bark.
Almond bark costs $0.33 more per ounce than peanut brittle.
The difference between the cost of one candy per ounce and the other candy is that: Almond bark costs $0.50 more per ounce than peanut brittle.
How to determine the cost of candy?Mathematically, a direct proportion can be represented the following mathematical expression:
y = kx
Where:
x represents the weight in ounces of a candy.y represents the cost in dollars of a candy.k represents the constant of proportionality.Next, we would determine the constant of proportionality (k) for each candy as follows:
For Peanut Brittle, we have the following:
Constant of proportionality (k) = 10/10
Constant of proportionality (k) = 1.0
For Almond Bark, we have the following:
Constant of proportionality (k) = 3/2
Constant of proportionality (k) = 1.5
Next, we would determine the difference in cost:
Difference in cost = 1.5 - 1.0
Difference in cost = $0.50.

they sold 3/8 of them. How many turkeys were sold on Sunday? Solve the problem
using the Draw a Diagram strategy.
The number of turkeys that they sold on Sunday is 90 turkeys
Total number of turkeys = 240
On Sunday, they sold 3/8 of them
The fraction of turkeys they sold on Sunday = 3/8
To find the number of turkeys that they sold on Sunday we have to find the 3/8 fraction of 240
Then,
The number of turkeys that they sold on Sunday = Total number of turkeys × The fraction of turkeys they sold on Sunday
Substitute the values in the equation
The number of turkeys that they sold on Sunday = 240 × 3/8
= 240 × 0.375
= 90 turkeys
Hence, the number of turkeys that they sold on Sunday is 90 turkeys

The slope of the line is -3 and the equation of the line formed by the points is y + 3x = 6.
From the table we can see that the line passes through the points:
(-6,6) ,(5,-3) ,(4,0) and (3,3) .
Let us consider any two points on the line (4,0) and (3,3) .
We know that the slope of the line can be found by using the intercept formula
Hence slope = (3-0) / (3-4) = 3/ -1 = -3
Now the equation of the line is :
y - 3 = -3(x-3)
or, y - 3 = -3x +9
or, y + 3x = 6
The letter m is frequently used to represent the slope of an object that resembles a line in the plane that contains the x and y axes. The slope is defined as the difference in two independent locations along the line expressed in y coordinate less by the equivalent difference in x coordinate.
