Mathematical expressions can be used to depict situations or issues, and algebra is the field of mathematics that does this. For a mathematical expression to have meaning, it needs to include variables like x, y, and z as well as mathematical operations like addition, subtraction, multiplication, and division. Algebra is used in every area of mathematics, including coordinate geometry, calculus, and trigonometry. A straightforward algebraic expression is 2x + 4 = 8.

Given that : first day of ticket sales the school sold 14 adult tickets and 5 student tickets for a total of $140. The school took in $190 on the second day by selling 10 adult tickets and 10 student tickets.

Let the price for adult ticket x and for student ticket y

we have ,

14x + 5y =140.....(i)

10x  + 10y = 190....(ii)

10 x + 10y = 190

x + y = 19

y = 19-x .....(iii)

put the value of y in equation i

14x + 5(19-x) = 140

14x + 95 - 5x = 140

9x = 45

x = 5

Now put value of x in equation iii

y = 19 - 5

y = 14

The price of one adult ticket is $5 and one student ticket is $14

No, a fraction is not a term. The distributive property can be applied to fractions because it is a general mathematical principle.

A fraction is not considered a term in the traditional sense. It is a mathematical expression that represents division. However, the distributive property can still be applied to fractions because the property itself is a fundamental rule of arithmetic that extends beyond specific types of expressions.

The distributive property states that for any real numbers a, b, and c:

a × (b + c) = (a × b) + (a × c).

When working with fractions, we can apply the distributive property as follows:

Let's consider the expression: a × (b/c).

We can rewrite this as: (a × b)/c.

Now, let's distribute the 'a' to 'b' and 'c':

(a × b)/c = (a/c) × b.

In this step, we applied the distributive property to the fraction (a/c) by treating it as a whole.

Although fractions represent division, we can still use the distributive property because it is a general mathematical principle that allows for manipulating expressions involving addition, subtraction, multiplication, and division.

The Yolanda's taxable income is $62,500.

What is income tax?

An income tax is a charge levied against people or organizations in relation to the income or profits they make. In most cases, income tax is calculated as the sum of the tax rate and the amount of taxable income. The type of taxpayer and the type of income are two factors that can affect the tax rate.

Given:

In 2008, Yolanda paid $3,875 in Social Security tax.

The Social Security tax rate was 6.2% to the maximum income of $94,200 that year.

Lets assume Yolanda´s income be `x`.

Now, calculating the taxable income of Yolanda

6.2% x (x) = 3875

\(\frac{6.2}{100} (x) = 3875\\x = 3875(\frac{100}{6.2}) \\x = 62500\)

Hence, the Yolanda's taxable income is $62,500.

The probability that at most 2 accounting majors are on the committee is 60.6%.

To solve this problem, we can use the binomial probability formula:

P(X ≤ 2) = ΣP(X = i), where i = 0, 1, or 2

P(X = i) = (n choose i) * p^i * (1-p)^(n-i)

where n is the total number of available majors (18), p is the probability of selecting an accounting major (10/18), and (n choose i) is the binomial coefficient which gives the number of ways to select i accounting majors from n total majors.

So, to find the probability that at most 2 accounting majors are on the committee, we need to sum the probabilities of selecting 0, 1, or 2 accounting majors.

P(X = 0) = (8 choose 5) * (10/18)^0 * (8/18)^5 = 0.018
P(X = 1) = (10 choose 1) * (10/18)^1 * (8/18)^4 = 0.219
P(X = 2) = (10 choose 2) * (10/18)^2 * (8/18)^3 = 0.369

Therefore, P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.018 + 0.219 + 0.369 = 0.606 or 60.6%

So the probability that at most 2 accounting majors are on the committee is 60.6%.

To find f(g(x)), substitute g(x) into f(x). Simplifying gives f(g(x)) = log6(36g(x)). For range of y in f(x) + g(x), Take possible values . Since log6(36x) is defined for x > 0, and 6 is positive, the range of y is (0, ∞).

a) To find f(g(x)), we substitute g(x) into f(x):

f(g(x)) = f(6x) = log6(36(6x)) = log6(216x) = log6(6^3x) = 3log6(6x) = 3(log6(6) + log6(x)) = 3(1 + log6(x)) = 3 + 3log6(x).

Thus, f(g(x)) simplifies to 3 + 3log6(x).

(b) To find the range of y in f(x) + g(x), we need to consider the possible values of f(x) and g(x). Since log6(36x) is defined for x > 0, and 6* is always positive, the range of f(x) is (0, ∞). Similarly, g(x) = 6* is always positive, so the range of g(x) is also (0, ∞).When we add f(x) and g(x), we are adding two positive functions, resulting in values greater than 0. Therefore, the range of y in f(x) + g(x) is (0, ∞).

If both pipes are open, the outlet pipe will empty the tank faster than the inlet pipe can fill it, and the tank will never be filled.

Let us consider the work done by the inlet pipe as positive (+) and the work done by the outlet pipe as negative (-). Suppose the work done by the inlet pipe is represented as x, and the work done by the outlet pipe is -3x.

We know that the time taken by the inlet pipe to fill the tank is 8 hours. Therefore, we can determine the rate of work of the inlet pipe as:

Rate of work = Work done / Time taken = x / 8

Since the outlet pipe is emptying the tank, its rate of work is negative. We are given that it takes 3 times as long for the outlet pipe to empty the tank compared to the inlet pipe to fill it. Thus, the outlet pipe takes 8 x 3 = 24 hours to empty the tank, and its rate of work is:

-3x / 24 = -x / 8

The question asks how long it will take to fill the tank if both pipes are open. When both pipes are open, their rates of work add up. Hence, we can state that:

Rate of work of both pipes = x / 8 - x / 8 = 0

We know that work done is given by the equation: Work done = Rate of work x Time taken

Therefore, the work done by both pipes is: 0 x t = 0, where t represents the time taken to fill the tank with both pipes open. This implies that the work done by the inlet pipe must equal the work done by the outlet pipe. In other words:

x = -3x / 24

Multiplying both sides by 24 gives us:

24x = -3x

Simplifying this equation yields:

27x = 0

x = 0

Thus, the inlet pipe and outlet pipe cancel each other out when they are open together. This means that the tank will never get filled. However, this scenario is impossible given the fact that the tank can be filled by the inlet pipe alone in 8 hours.

Therefore, it is not possible to fill the tank if both pipes are open. The reason is that the outlet pipe takes 24 hours to empty the tank, which is three times as long as it takes the inlet pipe to fill it. Consequently, if both pipes are open, the outlet pipe will empty the tank faster than the inlet pipe can fill it, and the tank will never be filled.

So, on solving the provided question we can say that Percent = 140/250 x100 = 56%

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.

A percentage is a ratio of one unit of an event's result to the entire sample multiplied by 100%. It denotes parts per 100. We divide the percentage of the sample that liked the options by the total sample to arrive at the calculation. As a result, we compute:

Percent = 140/250 x100 = 56%

Answer:

14400 boxes

Step-by-step explanation:

After looking at this question you would first see that it is looking for how many cuboids can fit into the container. That would mean that the final equation should be the volume of container divided by the volume of the cuboid.

First, we can find the volume of the container. Keep in mind that the volume of a rectangular prism is V=Bh (which means area of the base times the height)

For the base we would do (600)(200) which is 120000

Next, the height is 300, so we would times that by 120000 (which is 36000000)

Moving on to the cuboid!

We would do the same process, but with smaller units.

(same equation) V=Bh

B= (50)(20)

=100

(100)(25)=2500

Lastly, like mentioned in the beginning, take the volume of the container and divide by the volume of the cuboid.

36000000/2500=14400

Therefore, 14400 boxes can fit into this container!

Hope this helps! :)

Answer:

Step-by-step explanation:

so they made the boxes fit perfectly into the container.. as they are.

notice that each of the dimensions of the box fit perfectly into the dimensions of the container.

length container of 600 / length of box 50=12

width of container of  200 / width of box 20 = 10

height of container of 300 / heigth of box 25 = 12

The function is not defined at \(B\), so we cannot determine the behavior of \(f(x)\) in this interval.

To find the critical numbers and determine the intervals of increase or decrease for the function \(f(x) = 7x + 5x^{-1}\), we need to find the values of \(A\), \(B\), and \(C\), and analyze the intervals accordingly.

Step 1: Find the critical numbers

Critical numbers occur where the derivative of the function is either zero or undefined. Let's find the derivative of \(f(x)\):

\(f'(x) = 7 - 5x^{-2}\)

To find the critical numbers, we set \(f'(x) = 0\) and solve for \(x\):

\(7 - 5x^{-2} = 0\)

\(5x^{-2} = 7\)

\(x^{-2} = \frac{7}{5}\)

Taking the reciprocal of both sides:

\(x^2 = \frac{5}{7}\)

\(x = \pm \sqrt{\frac{5}{7}}\)

Thus, the critical numbers are \(A = -\sqrt{\frac{5}{7}}\) and \(C = \sqrt{\frac{5}{7}}\).

Step 2: Determine the intervals of increase or decrease

To analyze the intervals of increase or decrease, we need to consider the sign of the derivative in each interval.

\((-\infty, A]\): To the left of \(A\), the derivative is positive since \(f'(x) = 7 - 5x^{-2}\) is positive for \(x < A = -\sqrt{\frac{5}{7}}\). Therefore, \(f(x)\) is increasing in this interval. (INC)

\([A, B)\): The function is not defined at \(B\), so we cannot determine the behavior of \(f(x)\) in this interval.

\((B, C]\): The function is not defined at \(B\), so we cannot determine the behavior of \(f(x)\) in this interval.

\([C, \infty)\): To the right of \(C\), the derivative is negative since \(f'(x) = 7 - 5x^{-2}\) is negative for \(x > C = \sqrt{\frac{5}{7}}\). Therefore, \(f(x)\) is decreasing in this interval. (DEC)

\((-\infty, B)\): The function is not defined at \(B\), so we cannot determine the behavior of \(f(x)\) in this interval.

\((B, \infty)\): The function is not defined at \(B\), so we cannot determine the behavior of \(f(x)\) in this interval.

In summary:

\((-\infty, A]\): \(f(x)\) is increasing (INC).

\[A, B)\): Behavior cannot be determined.

\((B, C]\): Behavior cannot be determined.

\([C, \infty)\): \(f(x)\) is decreasing (DEC).

\((-\infty, B)\): Behavior cannot be determined.
