O produtor rural Ricardo Antunes Peixoto, 55 anos, teve uma surpresa enquanto perfurava um poço artesiano em sua fazenda, na zona rural de Brasília de Minas (MG). "Não saiu água, mas saiu fogo", diz, espantado. Uma equipe com cinco operários de uma empresa especializada trabalhou durante dois dias na propriedade para abrir o poço de água, mas, após escavarem 204 metros, o que encontraram foi um produto inflamável, que seria gás natural. O dono da fazenda Lagoa Misteriosa espera lucrar com a descoberta da reserva de gás. "Pelo menos, que se têm notícias no estado, este é o primeiro caso. Agora, com o dinheiro que eu vender o gás, vou abrir [um novo poço] para ter a minha água". Disponível em: . Acesso em: 12 abr. 2013. Considerando a combustão completa do metano, nas CNTP, determine a energia liberada na queima de 224 L de metano que foi em encontrado no poço desse agricultor.

How is adding two negative fractions similar to adding two negative integers?
Let U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, A = {1, 3, 5, 7, 9}, B = {2, 4, 6, 8, 10}, and C = {1, 2, 4, 5, 8, 9}. List the elements of each set.
Answer:
[tex]C\ n\ C^c = \{ \}[/tex]
[tex](A\ n\ C)^c = \{2,3,4,6,7,8,10\}[/tex]
[tex]A\ u\ (B\ n\ C) = \{1, 2,3, 4,5, 7, 8,9\}[/tex]
Step-by-step explanation:
Required
Determine
[tex]C\ n\ C^c[/tex]
[tex](A\ n\ C)^c[/tex]
[tex]A\ u\ (B\ n\ C)[/tex]
Solving [tex]C\ n\ C^c[/tex]
[tex]C^c[/tex] implies that elements in U but not in C
Since
[tex]C = \{1, 2, 4, 5, 8, 9\}[/tex]
[tex]C^c = \{3, 6, 7, 10\}[/tex]
[tex]C\ n\ C^c = \{1, 2, 4, 5, 8, 9\}\ n\ \{3, 6, 7, 10\}[/tex]
[tex]C\ n\ C^c = \{ \}[/tex]
Because there's no intersection between both
Solving [tex](A\ n\ C)^c[/tex]
First, we need to determine A n C
[tex]A\ n\ C = \{1, 3, 5, 7, 9\}\ n\ \{1, 2, 4, 5, 8, 9\}[/tex]
[tex]A\ n\ C = \{1, 5, 9\}[/tex]
[tex](A\ n\ C)^c = (\{1, 5, 9\})^c[/tex]
[tex](A\ n\ C)^c = \{2,3,4,6,7,8,10\}[/tex]
Solving [tex]A\ u\ (B\ n\ C)[/tex]
First, we need to determine B n C
[tex]B\ n\ C = \{2, 4, 6, 8, 10\}\ n\ \{1, 2, 4, 5, 8, 9\}[/tex]
[tex]B\ n\ C = \{2, 4, 8\}[/tex]
So:
[tex]A\ u\ (B\ n\ C) = \{1, 3, 5, 7, 9\}\ u\ \{2,4,8\}[/tex]
[tex]A\ u\ (B\ n\ C) = \{1, 2,3, 4,5, 7, 8,9\}[/tex]
The graph models projected populations, in thousand, of two towns after x years. Both towns experience a 1.9% annual growth rate. Which equation represents g(x) as a translation of f(x)?
The image of the graph is missing, so i have attached it.
Answer:
g(x) = 5/3 * f(x)
Step-by-step explanation:
We want to find the equation represents g(x) as a translation of f(x).
From the graph, the y = f(x) function curve has the following observations,
- At x = 0, y = f(0) = 30
- At x = 10, y = f(10) = 36
Similarly, from the graph, the y = g(x) function curve has the following observations,
- At x = 0, y = g(0) = 50
- At x = 10, y = g(10) = 60
From those coordinates on the graph, we can see that;
f(0) = 30 and g(0) = 50
It means that for us to make g(x) as a translation of f(x), g(0) = fraction * f(0)
Fraction = g(0)/f(0) = 50/30 = 5/3
Thus;
g(x) = 5/3 * f(x)
Let's confirm with the second coordinate;
Thus;
g(10) = 5/3 * f(10)
g(10) = 5/3 * 36
g(10) = 60
This value is same as what is on graph, thus we can conclude that;
The equation represents g(x) as a translation of f(x) is; g(x) = 5/3 * f(x)

What are corresponding angles?The angles that are in the same position on a given two parallel lines intersected by a transversal line are called the corresponding angles.
Corresponding angles are always equal.
We can also have alternate angles which are always equal.
We can also have alternate interior and exterior angles which are equal.
The angles on the same side make upto 180 degrees
We have,
DE is parallel to XY.
This means,
110 and x are corresponding angles.
Now,
The corresponding angles are equal.
So,
x = 110
Thus,
The value of x in the diagram is 110.

The school production of Our Town' was a big success. For opening night. 434 tickets were sold. Students paid $4.00 each, while non students paid $6.00 each. If a total of $2032.00 was collected, how many students and how
many non students attended
The number of students was (Simplify your answer)
The number of non-students was (Simplify your answer)
Answer:
286 students attended
148 non students attended
Step-by-step explanation:
Given
[tex]Tickets = 434[/tex]
[tex]Students = \$4.00[/tex]
[tex]Non-Students = \$6.00[/tex]
[tex]Total = \$2032.00[/tex]
Solving (a): Number of students
Represent students with S and non students with N
So:
[tex]S + N = 434[/tex] --- (1)
[tex]4S + 6N = 2032[/tex] --- (2)
Make N the subject of formula in (1)
[tex]N = 434 - S[/tex]
Substitute 434 - S for N in (2)
[tex]4S +6(434 - S) = 2032[/tex]
Open Bracket
[tex]4S + 2604 - 6S = 2032[/tex]
Collect Like Terms
[tex]4S - 6S = 2032 - 2604[/tex]
[tex]-2S = -572[/tex]
Divide through by -2
[tex]S = 286[/tex]
Hence; 286 students attended
Solving (b):
Recall that
[tex]N = 434 - S[/tex]
[tex]N = 434 - 286[/tex]
[tex]N = 148[/tex]
148 non students attended

Crash Course in Accounting and Financial Statement Analysis, Second Edition by Matan Feldman, Arkady Libman
Changes in Accounts Receivable
Recall that net income (the last line on the income statement and the first line on the cash flow statement) captures revenues and expenses based on the accrual method of accounting. As such, credit sales, in addition to cash sales, may be recorded as revenues.
The sales generated on credit are recorded on the balance sheet as accounts receivable, while cash revenues are recorded on the balance sheet as cash.
I hope I explained well.
If accounts receivable increased from one year to the next, the implication is that more people paid on credit during the year, which represents a drain on cash for the company, as some of the revenues that came in during the year increased the accounts receivable balance instead of cash.
Conversely, if accounts receivable decreased from one year to the next, the implication is that those old accounts receivable were collected (i.e., credit sales were eventually converted into cash sales), representing cash inflow for the company.

There are three consecutive odd integers such that the sum of twice the second and the smallest is seven more than twice the largest. Find the sum of the integers.
Answer:
11 +13 + 15 = 39
Step-by-step explanation:
Let the consecutive odd integer be X , Y , Z .
X < Y < Z
Y = X + 2
Z = X + 4
Given ,
2 Y + X = 2 Z + 7
2 ( X + 2 ) + X = 2 ( X + 4 ) + 7
2 X + 4 + X = 2 X + 8 + 7
X = 15 - 4 = 11
So the integers are
11 , 13 , 15 .
Sum of integers = 39.
What’s is bigger -1 3/7 or -1 1/2
Answer:
-1 3/7 is largerStep-by-step explanation:
To figure out which is larger, convert each of these mixed numbers to decimals.
-1 3/7 = -1.42857142857
-1 1/2 = -1.5
Negative numbers are larger the closer they are to 0. So, -1 is larger than -2, since -1 is closer to 0.
Since -1.5 < -1.43, -1 3/7 is larger than -1 1/2 since it is closer to 0.

what value of a makes the equation true?
The value of a that makes the equation true is -1.55.
What is the value of a?In order to determine the value of a, take the following steps given this equation: 3(a+1.5)=-1.5
Divide both sides of the equation by 3: a + 1.5 - 1.5/3
a + 1.5 = -0.05
Subtract 1.5 from both sides of the equation : a = -0.05 - 1.5 = -1.55

66/2=$33
970/2=$485
485+33+26+12.50 = 556.50
After dividing, the total, Jenna and Harper will pay $556.5
What is division?In maths, a division is a process of splitting a specific amount into equal parts.
Given that, Jenna and Harper are living together and have agreed to split half of all living costs. Rent for the apartment is $970. The water bill is $52. The gas bill is $25, while the electric bill is $66.
We will divide the total bill into two equal parts to find how much one girl should pay.
Therefore,
The total expense = 970+52+25+66 = $1113
Since, both girls are splitting the bill into halves, therefore,
$1113 / 2 = $556.5
That mean, each will have to pay $556.5
Hence, both will pay $556.5
