A plastic bag contains 0.80 mol of gas and occupies a volume of 18 L. A leak in the bag allows gas to escape until the volume becomes 16 L. How many moles of gas remain in the bag?
0.31 mol
0.91 mol
0.51 mol
0.71 mol
To find the moles of gas remaining in the bag, we can use the initial and final volumes and the initial moles of gas. Since the temperature and pressure remain constant, we can use the formula:
Initial moles × Initial volume = Final moles × Final volume
0.80 mol × 18 L = Final moles × 16 L
Solve for the final moles:
(0.80 mol × 18 L) / 16 L = Final moles
14.4 mol / 16 L = Final moles
Final moles = 0.9 mol
So, 0.9 moles of gas remain in the bag after the leak. The closest answer is 0.91 mol, so the correct option is:
0.91 moles of gas remain in the bag.

in a choir the ratio of men to woman is 4:7. 25% of the men prefer classical songs, and 80% of the women prefer classical songs. What percentage of the choir prefer classical songs?
Answer:
60%
Step-by-step explanation:
percentage of men in the choir = (4/11) x 100 = 36.4%
percentage of women in the choir = (7/11) x 100 = 63.6%
Percentage of men in the choir that prefer classical songs = 36.4 x0.25 = 9.1%
Percentage of women in the choir that prefer classical songs = 0.8 x 63.6% = 50.9%
percentage of the choir prefer classical songs = 50.9% + 9.1% = 60%
The line, y = 3x+2, is tangent to the circle with centre, C(-5,4), at the point Q.
Find the coordinates of Q.
The circle centered at C(-5,4) intersects the line y = 3x + 2 at the point Q, with coordinates (-1/10, 17/10). This point Q serves as the tangent point between the line and the circle.
To find the coordinates of the point Q where the line y = 3x + 2 is tangent to the circle with center C(-5,4), we can use the concept of the slope of a tangent line.
First, we need to find the slope of the tangent line. The slope of the line y = 3x + 2 is 3. For a tangent line to a circle, the radius drawn from the center of the circle to the point of tangency is perpendicular to the tangent line. Since the slope of the radius is the negative reciprocal of the tangent line's slope, the slope of the radius is -1/3.
Next, we find the equation of the radius line passing through the center C(-5,4) with a slope of -1/3. Using the point-slope form, we have:
y - 4 = (-1/3)(x + 5)
To find the point of tangency, we solve the system of equations formed by the line y = 3x + 2 and the radius line:
y = 3x + 2
y - 4 = (-1/3)(x + 5)
Substituting the value of y from the first equation into the second equation:
3x + 2 - 4 = (-1/3)(x + 5)
3x - 2 = (-1/3)x - 5/3
3x + (1/3)x = 5/3 - 2
(10/3)x = -1/3
x = -1/10
Substituting this value of x back into the first equation:
y = 3(-1/10) + 2
y = -3/10 + 20/10
y = 17/10
Therefore, the coordinates of the point Q, where the line y = 3x + 2 is tangent to the circle with center C(-5,4), are (-1/10, 17/10)

If you spin the spinner 57 times, what is the best prediction possible for the number of times it will land on pink or blue?
If the spinner has an equal chance of landing on each color, then the probability of landing on pink or blue is 1/2 or 0.5.
Using this probability, we can make the following prediction:
Expected number of times landing on pink or blue = probability of landing on pink or blue * number of spins
Expected number of times landing on pink or blue = 0.5 * 57
Expected number of times landing on pink or blue = 28.5
Therefore, the best prediction possible for the number of times the spinner will land on pink or blue is 28.5 times. However, it is important to note that this is only an expected value and the actual number of times it lands on pink or blue may vary

the average of 8 girls is 15 and the average of 6 girls is 13 find the average of the other two girls with equal age
Answer:
21
Step-by-step explanation:
Since the girls have the same age, let their age be x.
Then, their average is
\(\frac{x+x}{2} = \frac{2x}{2} = x\)
Let \(S_{i}\) denote the age of 'i' girls.
Then, \(S_{8} = S_{6} + x + x - eq(1)\)
Also, we have,
\(\frac{S_{8}}{8} =15 - eq(2)\)
\(\frac{S_{6}}{6} =13 - eq(3)\)
Then eq(2):
(from eq(1) and eq(3))
\(\frac{S_{6} + 2x}{8} =15\\\\\frac{13*6 + 2x}{8} = 15\\\\78+2x = 120\\\\2x = 120-78\\\\x = 21\)
The average of the other two girls with equal age is 21

1. What is the opportunity cost (in terms of poultry given up) of increasing the annual output of wheat from 900 to 1100 pounds? (10% of grade)
2. What is the opportunity cost (in terms of poultry given up) of increasing the annual output of wheat from 200 to 400 pounds? (10% of grade)
In the given scenario, the inhabitants of Life is Good island produce both wheat and poultry. The table provides the maximum annual output combinations of wheat and poultry that can be produced, based on the available resources and technology.
To determine the opportunity cost of increasing the annual output of wheat, we compare the quantity of poultry given up in each scenario. Specifically, we calculate the difference in poultry quantity between two output levels of wheat: from 900 to 1100 pounds, and from 200 to 400 pounds.
To calculate the opportunity cost of increasing the annual output of wheat from 900 to 1100 pounds, we need to compare the corresponding quantities of poultry. From the table, we can see that the quantity of poultry decreases from 450 pounds to 300 pounds when wheat production increases from 900 to 1100 pounds. Therefore, the opportunity cost of this increase in wheat output is 150 pounds of poultry (450 - 300).
Similarly, to calculate the opportunity cost of increasing the annual output of wheat from 200 to 400 pounds, we compare the quantities of poultry. The table shows that the poultry quantity decreases from 775 pounds to 725 pounds when wheat production increases from 200 to 400 pounds. Hence, the opportunity cost of this increase in wheat output is 50 pounds of poultry (775 - 725).
In both cases, the opportunity cost is determined by the reduction in poultry quantity resulting from an increase in wheat production.

What is the range of the function g(x) = |x – 12| – 2?
{y | y > –2}
{y | y > –2}
{y | y > 12}
{y | y > 12}
The range of the function g(x) = |x - 12| - 2 is {y | y > -2}, indicating that the function can take any value greater than -2.
To find the range of the function g(x) = |x - 12| - 2, we need to determine the set of all possible values that the function can take.
The absolute value function |x - 12| represents the distance between x and 12 on the number line. Since the absolute value always results in a non-negative value, the expression |x - 12| will always be greater than or equal to 0.
By subtracting 2 from |x - 12|, we shift the entire range downward by 2 units. This means that the minimum value of g(x) will be -2.
Therefore, the range of g(x) can be written as {y | y > -2}, which means that the function can take any value greater than -2. In other words, the range includes all real numbers greater than -2.
Visually, if we were to plot the graph of g(x), it would be a V-shaped graph with the vertex at (12, -2) and the arms extending upward infinitely. The function will never be less than -2 since we are subtracting 2 from the absolute value.

a population of a particular yeast cell develops with a constant relative growth rate of 0.4435 per hour. the initial population consists of 3.1 million cells. find the population size after 4 hours Round your answer to one decimal place.) P(5) = million cells
To find the population size after 4 hours, we can use the formula:
P(t) = P(0) * e^(rt)
where P(t) is the population size at time t, P(0) is the initial population size, r is the relative growth rate, and e is the mathematical constant approximately equal to 2.718.
Plugging in the given values, we get:
P(4) = 3.1 million * e^(0.4435 * 4)
P(4) = 3.1 million * e^(1.774)
P(4) = 3.1 million * 5.913
P(4) = 18.333 million cells
Therefore, the population size after 4 hours is 18.3 million cells (rounded to one decimal place).
Based on the given information, the population of yeast cells grows with a constant relative growth rate of 0.4435 per hour, and the initial population is 3.1 million cells. To find the population size after 4 hours, we can use the exponential growth formula:
P(t) = P0 * e^(rt)
where P(t) is the population size after t hours, P0 is the initial population (3.1 million cells), r is the growth rate (0.4435 per hour), and e is the base of the natural logarithm (approximately 2.71828).
For this problem, t = 4 hours. Plugging the values into the formula, we get:
P(4) = 3.1 * e^(0.4435 * 4)
Now, calculate the exponent:
0.4435 * 4 = 1.774
Then, calculate e raised to this power:
e^1.774 ≈ 5.897
Next, multiply this by the initial population:
3.1 * 5.897 ≈ 18.2797
So, after rounding the answer to one decimal place, the population size after 4 hours is approximately 18.3 million cells.
