Calculate δe, if q= 0.769 kj and w= -860 j .
The change in internal energy (δe) of the system, calculated using the first law of thermodynamics, and considering that the heat and work quantities are converted to the same unit, is 1629 J.
Explanation:The query you've presented seems to be about the first law of thermodynamics, which states that the change in internal energy (ΔE or in your notation, δe) of a system is equal to the heat (q) added to the system minus the work (w) done by the system. Both heat and work quantities need to be in the same units for this calculation, whereas your values are given in different units: kJ for heat and J for work. To facilitate this calculation, let's first convert the heat quantity from kJ to J (1 kJ equals 1000 J).
So, q = 0.769 kJ = 0.769 * 1000 J = 769 J.
Given, w = -860 J.
Now, according to the first law of thermodynamics, δe = q - w.
Substituting the given values, we get δe = 769 J - (-860 J) = 769 J + 860 J = 1629 J.
Therefore, the change in internal energy, δe, is 1629 J.

Final answer:
To represent the ticket sales information as a linear system, we use two equations: a + s = 330 for the total number of tickets, and 10a + 6s = 2380 for the total revenue from ticket sales.
Explanation:
The question involves writing a linear system of equations based on the information provided about ticket sales for a school event. Given that 330 tickets were sold in total, comprising adult tickets (a) and student tickets (s), and that the total revenue from these tickets was $2380, with student tickets priced at $6 each and adult tickets at $10 each, we can represent this scenario with two equations.
The first equation represents the total number of tickets: a + s = 330.
The second equation represents the total revenue: 10a + 6s = 2380.
This linear system can be solved to find the values of a and s, which would give us the number of adult and student tickets sold, respectively.
Which does not describe the same situation?
Answer:
y = 3+6x
Step-by-step explanation:
Let us substitute x = 0, then we get
y = 3
This is not the case as the graph clearly shows that when x = 3, then y = 2
y = 2+6x
when x = 0 then y = 2 which valid from the graph
Now put x values from the table into the equation
y = 2+6×-1
⇒y = -4
x = 0 already solved
x = 2
y = 2+6×2
⇒y = 14
All the values fit in the equation. So, the bottom two options are valid.
Hence, the first equation is not valid.

The surface area of a cone is given by the formula
S = πl + πr2. Solve the formula for l.
Answer:
l = (S - πr²) / π
Step-by-step explanation:
The problem gives us the formula for the surface area of a cone S, we will solve the formula for l.
The formula is
S = πl + πr²
If we take the πr² to the other side, we get:
S - πr² = πl
Now we divide by π, and we get:
(S - πr²) / π = l
Therefore solving for l, we get that
l = (S - πr²) / π.

Line segments JK and JL in the xy-coordinate plane both have a common endpoint J (-4,11) and midpoints at M1 (2,16) and M2 (-3,5). What's the distance between M1 and M2?
Answer:
12.08 units.
Step-by-step explanation:
We have been given that line segments JK and JL in the xy-coordinate plane both have a common endpoint J (-4,11) and midpoints at [tex]M_1 (2,16)[/tex] and [tex]M_2 (-3,5)[/tex].
To find the distance between [tex]M_1[/tex] and [tex]M_2[/tex] we will use distance formula.
[tex]\text{Distance}=\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}[/tex]
[tex]x_2[/tex] and [tex]x_1[/tex] are x-coordinates of two points.
[tex]y_2[/tex] and [tex]y_1[/tex] are corresponding y-coordinates of two points.
Let [tex]M_2[/tex] our first point, then [tex]x_1=-3[/tex] and [tex]y_1=5[/tex].
Let [tex]M_1[/tex] will be our second point, then [tex]x_2=2[/tex] and [tex]y_2=16[/tex]
Upon substituting coordinates of point [tex]M_1[/tex] and [tex]M_2[/tex] in distance formula we will get,
[tex]\text{Distance}=\sqrt{(2--3)^{2}+(16-5)^{2}}[/tex]
[tex]\text{Distance}=\sqrt{(2+3)^{2}+(11)^{2}}[/tex]
[tex]\text{Distance}=\sqrt{(5)^{2}+(11)^{2}}[/tex]
[tex]\text{Distance}=\sqrt{25+121}[/tex]
[tex]\text{Distance}=\sqrt{146}[/tex]
[tex]\text{Distance}=12.0830459735945721\approx 12.08[/tex]
Therefore, distance between [tex]M_1[/tex] and [tex]M_2[/tex] is 12.08 units.

Please help!!!!!!!!!
does x/x+6 simplify to 1/6 explain why or why not
No, it does not.
x and x + 6 are both prime and cannot be factored.
There are no common factors to divide out.
x over x + 6 is already simplified.
If you substitute in a value for x, the fraction will not be equal to 1/6.
The expression x/(x+6) does not simplify to 1/6 because there are no common factors in the numerator and denominator that can be canceled out.
The expression x/(x+6) does not simplify to 1/6. To understand this, we need to recognize that simplification involves reducing a fraction to its simplest form by factoring or canceling common factors in the numerator and the denominator.
If x were a factor in both the numerator and the denominator, then we could simplify by canceling out the x's.
However, in the expression x/(x+6), the term x+6 in the denominator cannot be simplified with x in the numerator because they are not factors of each other. They are connected by the addition of 6, which means that there are no common factors to cancel out.
The only way x/(x+6) would simplify to 1/6 is if 'x' were to be somehow removed from the denominator, leaving only the constant 6. But since this is not the case, the fraction cannot be simplified to 1/6. Therefore, the original expression is already at its simplest form unless a specific value is given for x, which may then allow further simplification.
The coordinate grid below shows triangle ABC and it's image after translation, triangle A'B'C':
Which of the following completes the rule for this translation, (x,y)>(x+4,__)?
y+4
y+2
y-4
y-2
Answer:
First option : y+4Step-by-step explanation:
Given triangle ABC and a translated triangle A'B'C'.
Coordinates of triangle ABC are
A(-1,-1)
B(-3,-3) and
C(2,-2).
Coordinates of triangle A'B'C' are
A'(3,3)
B'(1,1)
C'(6,2).
Let us check the translation is being applied there.
A(-1,-1) ---> A'(3,3)
We can see that A(-1,-1) ----> A'(-1+4, -1+4) to get (3,3).
Therefore, (x,y) ---> (x+4,y+4) rule is being applied there to get the translated triangle A'B'C'.
So, the correct option is first option:

Darryl has $5 left in his pocket. He spent $16 on a book, $20 on a compact disc, and $2 on a magazine. How much money did he have at the beginning of the day?
Darryl had $43 at the beginning of the day.
Let's denote the initial amount of money Darryl had as [tex]\( M \)[/tex].
He spent $16 on a book, which we can denote as [tex]\( S_{book} = \$16 \)[/tex].
He spent $20 on a compact disc, which we can denote as [tex]\( S_{CD} = \$20 \)[/tex].
He spent $2 on a magazine, which we can denote as [tex]\( S_{magazine} = \$2 \)[/tex].
He has $5 left at the end of the day, which we can denote as [tex]\( L = \$5 \)[/tex].
The total amount spent, [tex]\( S_{total} \)[/tex], is the sum of the amounts spent on the book, the compact disc, and the magazine:
[tex]\[ S_{total} = S_{book} + S_{CD} + S_{magazine} \][/tex]
[tex]\[ S_{total} = \$16 + \$20 + \$2 \][/tex]
[tex]\[ S_{total} = \$38 \][/tex]
The initial amount of money Darryl had, [tex]\( M \)[/tex], is the sum of the total amount spent and the amount left:
[tex]\[ M = S_{total} + L \][/tex]
[tex]\[ M = \$38 + \$5 \][/tex]
[tex]\[ M = \$43 \][/tex]
