A total of 504 tickets were sold for the school play. They were either adult tickets or student tickets. There were 54 more student tickets sold than adult tickets. How many adult tickets were sold?
Using algebra, we find that 225 adult tickets were sold out of a total of 504 tickets.
Explanation:Let's denote the number of adult tickets as x. Since there were 54 more student tickets sold than adult tickets, we can represent the number of student tickets as x + 54. The total number of tickets sold is 504, so we set up the equation x + (x + 54) = 504.
Combining like terms, we get 2x + 54 = 504. Subtracting 54 from both sides gives us 2x = 450. Finally, dividing both sides by 2 gives us x = 225.
Therefore, 225 adult tickets were sold.

A bird feeder is in the shape of a cylinder. It has a volume of about 100 cubic inches. It has a radius of 2 inches. What is the approximate height of the bird feeder? Use 3.14 for pi
volume = pi x r^2x h
100 = 3.14 x 2^2 x h
100 =3.14 x 4 x h
100 = 12.56 x h
h = 100/12.56 = 7.9617
the height is approximately 8 inches tall

Find the value of y, rounded to the nearest tenth. Please help me, I'd appreciate it!!
Suppose y varies directly with x, and y = 8 when x = –6. What direct variation equation relates x and y? What is the value of y when x = –2?
Answer:
Direct variation states that the relationship between two variables in which one is a constant multiple of the other one.
In other words, when one variable changes the other one changes in proportion to the first.
i.e, if y is directly proportional to x then, the equal will be of the form is, y= kx where k is the constant of variation.
Given: y varies directly with x, and y = 8 when x = –6
By definition of direct variation,
y = kx
Substitute the values of x = -6 and y=8 to solve for k;
8 = -6k
Divide both sides by -6 we get;
[tex]k = -\frac{8}{6} = -\frac{4}{3}[/tex]
Now, to find the value of y when x = 2 we have;
[tex]y = -\frac{4}{3}x[/tex]
Substitute the given value of x =-2 we have;
[tex]y = -\frac{4}{3} \cdot -2 = \frac{8}{3}[/tex]
Therefore, the direct variation related x and y is, [tex]y = -\frac{4}{3}x[/tex]
and the value of [tex]y =\frac{8}{3}[/tex] when x = -2

Tommy has a piece of toast that has butter on one side, and he dropped it twice. Both times, it landed with the butter side up. If he drops it two more times, what is the probability that it will have landed butter side up a total of three times?
Answer: The required probability is 50%.
Step-by-step explanation: Given that Tommy has a piece of toast that has butter on one side.
The first two times dropped the piece, it landed with the butter side up.
We are to find the probability that the piece will have landed butter side up a total of three times, if he drops it two more times.
For the butter side to be landed up three times, one of the last two drops must land butter side up.
Let, 'S' denotes the sample space for the experiment of dropping the piece for the last two times, then
n(S) = 2.
Let, 'B' be the event of getting one of the last two drops landed butter side up, then
n(B) = 1.
Therefore, the probability of getting one of the last two drops landed butter side up will be
[tex]P(B)=\dfrac{n(B)}{n(S)}=\dfrac{1}{2}=50\%.[/tex]
Thus, there is 50% probability of landing butter side up a total of three times.

A rectangular garden has a length of 12 feet. You need 36 feet of fencing to enclose the garden. What is the width of the garden.
The width of the rectangular garden is 6 feet with a perimeter of 36 feet.
What are the area and perimeter of a rectangle?We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
Given, A rectangular garden has a length of 12 feet.
Assuming the width of the garden to be x feet.
We know the perimeter of a rectangle is 2(length + width).
∴ 2(12 + x) = 36.
24 + 2x = 36.
2x = 12.
x = 6 Or the width is 6 feet.

True or False: The sample size you need to estimate the population distribution should always be at least 10% of the population size.
False. The sample size needed to estimate the population distribution should not always be at least 10% of the population size.
Explanation:False. The statement that the sample size needed to estimate the population distribution should always be at least 10% of the population size is not true. The size of the sample needed depends on various factors such as the original population, the level of confidence desired, and the margin of error allowed. For example, if the population is large and diverse, a smaller sample may still provide a reliable estimate of the population distribution. It is important to consider statistical concepts such as normal distribution and sampling techniques when determining the appropriate sample size.

Evaluate the limit, if it exists. (if an answer does not exist, enter dne.)lim h → 0 (x + h)3 − x3h
To evaluate the limit of (x + h)³ - x³h as h approaches 0, we can expand the expression using the binomial theorem and simplify. The resulting expression can be factored to show that as h approaches 0, the entire expression becomes 0. Therefore, the limit is 0.
Explanation:To evaluate the given limit, we can start by expanding the expression (x + h)³ using the binomial theorem. This gives us (x³ + 3x²h + 3xh² + h³) - x³h. Simplifying further, we can cancel out the x³ terms and obtain 3x²h + 3xh² + h³ - x³h. Now, we can factor out h from the expression to get h(3x² + 3xh + h² - x³). As h approaches 0, the entire expression becomes 0, since h is being multiplied by a polynomial that does not contain h. Therefore, the limit is 0.

Sales tax on an item is directly proportional to the cost of the item purchased. If the tax on a $500 item is $30, what is the sales tax on a $900 item?
Answer: $54
Step-by-step explanation:
The equation to show the direct variation in two quantities x and y is given by :-
[tex]\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}[/tex]
The tax on a $500 item is $30.
Let 'x' be the sales tax on a $900 item.
Then , we have the following equation:-
[tex]\dfrac{x}{900}=\dfrac{30}{500}\\\\\Rightarrow\ x=\dfrac{900\times30}{500}\\\\\Rightarrow\ x=54[/tex]
Hence, the sales tax on a $900 item = $54
the base of this solid crate has an area of 6 square centimeters the height of the crate is 4 meters what is the volume of the crate
Answer:
2 × 10³ cm³
Step-by-step explanation:
Given data
Area of the base: 6 cm²Height of the crate: 4 m = 4 × 10² cmConsidering the crate is a cuboid, its volume (V) is:
V = length × width × height
Since
area of the base = length × width
We get
V = area of the base × height
V = 6 cm² × 4 × 10² cm
V = 2.4 × 10³ cm³ ≈ 2 × 10³ cm³ (we round off to 1 significant figure)

The first card selected from a standard 52-card deck was a king. if it is not returned to the deck, what is the probability that a king will be drawn on the second selection?
there would be 3 kings left and 51 cards left
so it would be a 3/51 which reduces to 1/17 probability
The probability of drawing a king from a 52-card deck on the second draw, given that a king was drawn on the first draw and was not replaced, is 1 in 17.
Explanation:The question pertains to the concept of probability, specifically with regards to sampling without replacement in a 52-card deck. First, let's identify the elements: there are 4 kings in a 52-card deck. When one king is drawn and not replaced, there are now 51 cards left with 3 kings.
The probability of drawing a king on the second draw, with the first king not replaced, is the number of favorable outcomes (drawing a king) divided by the total number of outcomes (total cards left). Hence, the probability is 3/51 = 1/17.
This means that there is 1 chance in 17 of drawing a king on the second draw if a king has been drawn on the first draw and not replaced.
