When solving a system of equations with two unknowns, one of the techniques to find the unknown values is the substitution method. In this method, one equation is substituted to the other equation to achieve a final equation that contains only one of the unknowns. The value remaining unknown can be derived directly from the final equation. By substituting the first value to one of the original equations, the other unknown may be derived.

Let A be the number of adult tickets sold and S be the number of student tickets sold.

The total tickets sold is 275.

A + S = 275_________(Eq. 1)

Also, the total sales is $1025.

5A + 3S = 1,025_______(Eq. 2)

From the Equation 1

S = 275 - A     [Subtract A from both sides]

Using this value of S, substitute S in the second equation.

5A + 3(275 - A) = 1,025

5A + 825 - 3A = 1,025

2A = 200 [Subtract both sides 825]

A = 100   [Divide both sides by 2]

Hence, There were 100 adult tickets sold.

Answer: To determine if a set of dimensions is possible for the container, we need to check if it satisfies both the inequality h > 0.3r^2 and the two constraints.

A) radius = 21 inches, height = 21 inches:

The inequality h > 0.3r^2 is satisfied (21 > 0.3 * 21^2).

The height must be no more than 15 inches greater than the radius (21 - 21 <= 15), which is satisfied.

The area of the base must be at least 36pi square inches (pi * r^2 >= 36pi), which is not satisfied (pi * 21^2 < 36pi).

So, option A is not a possible set of dimensions.

B) radius = 8 inches, height = 21 inches:

The inequality h > 0.3r^2 is satisfied (21 > 0.3 * 8^2).

The height must be no more than 15 inches greater than the radius (21 - 8 <= 15), which is satisfied.

The area of the base must be at least 36pi square inches (pi * r^2 >= 36pi), which is satisfied (pi * 8^2 >= 36pi).

So, option B is a possible set of dimensions.

C) radius = 7 inches, height = 23 inches:

The inequality h > 0.3r^2 is satisfied (23 > 0.3 * 7^2).

The height must be no more than 15 inches greater than the radius (23 - 7 <= 15), which is satisfied.

The area of the base must be at least 36pi square inches (pi * r^2 >= 36pi), which is not satisfied (pi * 7^2 < 36pi).

So, option C is not a possible set of dimensions.

D) radius = 9 inches, height = 18 inches:

The inequality h > 0.3r^2 is not satisfied (18 <= 0.3 * 9^2).

The height must be no more than 15 inches greater than the radius (18 - 9 <= 15), which is not satisfied.

So, option D is not a possible set of dimensions.

Therefore, the only possible set of dimensions is B) radius = 8 inches, height = 21 inches.

Below

Step-by-step explanation:

1)   The domain can be ANY value of 'x' except 'x' that cause the denominator to = 0    and it cannot be 'x' values that cause the denominator to be negative    as this is not allowed

so   x cannot be 5 or greater

       (-∞ , 5)   is the domain in interval notation

    or you could just write   x < 5      

2) you cannot have a negative square root so the domain would be all 'a'

       that the numerator would be 0 or greater (you CAN have a square root of '0' in the numerator)

             7-5a ≥ 0

               7 ≥ 5a

               7/5 ≥ a     or flipping it around    a ≤ 7/5

3) 15x^3y^2 + 10x^2 y - 20 x^2 y^3

Answer: Let's call the hourly rate for regular work as "r" and the hourly rate for overtime work as "o".

From the information given, we know that 80 hours of regular work earned Andrew 80 * r = $920.65.

And we also know that 5 hours of overtime work earned him 5 * o = $109.80.

So, combining the two amounts, we have:

80 * r + 5 * o = $1030.45

Now, we can substitute the first equation into the second:

80 * r + 5 * o = $1030.45

80 * r = $920.65

80 * r + 5 * o = $1030.45

5 * o = $1030.45 - $920.65

5 * o = $109.80

Finally, we can solve for the hourly rate of overtime work:

o = $109.80 / 5

o = $21.96/hour

The correct answer is option D: Chen read for less time because an hour a day for 7 days is equal to 210 minutes.

To determine the correct answer, we need to use the unitary method. This method involves converting the units of measurement into a common unit and then comparing them.

In this case, we need to convert hours into minutes to compare the reading time of Sierra and Chen.

An hour is equal to 60 minutes. Therefore, 1 hour a day for 7 days is equal to

=> 60 minutes * 7 days = 420 minutes.

However, we need to divide this number by 2 because Chen only read for half an hour a day. Hence, Chen read for 210 minutes

=> (420 minutes / 2).

Now that we have both the reading times in minutes, we can compare them. Sierra read for 220 minutes while Chen read for 210 minutes. As 220 > 210, it is clear that Sierra read for more time.

In conclusion, option D is the correct answer as Chen read for less time because an hour a day for 7 days is equal to 210 minutes. The unitary method is useful in comparing measurements with different units and it provides us with accurate results.

Complete Question:

Sierra read for 220 minutes in 1week. Chen read for an hour a day for 7 days. Which explanation is correct?

The measures of both pairs of opposite sides are equal in length using the properties of rotations.

What is rotation?

In mathematics, a rotation is a transformation that spins a shape around an immovable object.

We are given that M is the midpoint of the diagonals.  

Since, M is the midpoint of the diagonals, so, VM = MQ and TM = MN.

Since T and N are equidistant from M, and the measure of ∠TMN = 180°, So, r(180°, M)(T) = N

Similarly, r(180°, M)(V) = Q  

We can rotate every point on TV in this same way.

So,  r(180°, M)(TV) = QN

Similarly, r(180°, M)(TQ) = VN  

Since, the rotations are rigid motions and they preserve distance, so, TV=QN and TQ=VN.

Hence, the measures of both pairs of opposite sides are equal in length.

The value changes from 5/4 to 3/8 , then the percent of change from 5/4 to 3/8 is a 60% increase. So, the value change from 5/4 to 3/8 increases in percentage.

To determine whether the percent of change is an increase or a decrease, you need to calculate the difference between the old value and the new value as a percentage of the old value.

The old value is 5/4 and the new value is 3/8. To calculate the difference, you subtract the new value from the old value: 5/4 - 3/8 = 5/4 - 3/8 = 15/32.

Next, you need to express the difference as a percentage of the old value. To do this, you divide the difference by the old value and multiply by 100%. That gives you (15/32) / (5/4) * 100% = 60%.

Since the result is a positive percentage, it means that the percent of change is an increase. So, the percent of change from 5/4 to 3/8 is a 60% increase.

One element within an experiment that allows you to increase the level of certainty in your results and account for random events is the use of a control group.

Level of certainty refers to the degree of confidence or assurance that one has in the accuracy of a particular result, decision, or conclusion. In scientific research, the level of certainty is often expressed as a probability or as a confidence interval, which provides a range of values that are expected to contain the true value with a certain degree of confidence. A higher level of certainty indicates a greater level of confidence that the result is correct, while a lower level of certainty indicates more uncertainty or ambiguity. Factors that can affect the level of certainty in an experiment or measurement include the quality of the data, the size of the sample, the accuracy of the methods used, and the presence of random or systematic errors.

By having a control group, you can compare the results of the experiment against a baseline and isolate any changes caused by the independent variable. Additionally, using a large sample size and repeating the experiment multiple times can also help increase the level of certainty and account for random events.

In this particular study, Selection bias, Response bias, non response bias and Self-selection bias may exist.

There are several biases that may exist in the study:

1. Selection bias: By only calling people whose names were randomly sampled from the phone book, the study may not accurately represent the population of the state as a whole. Mobile phones and unlisted numbers, which may represent a significant portion of the population, are not included in phone books and therefore not included in the sample.

2. Response bias: The study only includes people who answered the phone when the senator's office called. This means that the sample only represents people who were available and willing to participate in the study. People who were not available or unwilling to participate may have different opinions, which would introduce a response bias.

3. Nonresponse bias: People who did not answer the phone when the senator's office called may have different opinions than those who answered. This nonresponse bias can result in an overestimation or underestimation of the true population values.

4. Self-selection bias: By only calling people who answered the phone, the study may only represent those who are interested in politics or are more likely to participate in political surveys. This self-selection bias can result in an overestimation or underestimation of the true population values.
