tickets to a movie cost $10.50 for adults and $7.25 for students. you and a few friends purchased 8 tickets for $61.25. how many adult tickets and student tickets were purchased?
Answer:
1 adult ticket and 7 student tickets were purchased
Step-by-step explanation:
let a represent number of adult tickets purchased and s the number of student tickets purchased, then
a + s = 8 ( subtract s from both sides )
a = 8 - s → (1) ← based on total tickets purchased
10.5a + 7.25s = 61.25 → (2) ← based on cost of tickets
substitute a = 8 - s into (2)
10.5(8 - s) + 7.25s = 61.25
84 - 10.5s + 7.25s = 61.25
84 - 3.25s = 61.25 ( subtract 84 from both sides )
- 3.25s = - 22.75 ( divide both sides by - 3.25 )
s = 7
substitute s = 7 into (1)
a = 8 - 7 = 1
that is 1 adult ticket and 7 student tickets were purchased
Consider the line 5x+2y=−4. What is the equation of the line parallel to the given line that passes through the point (−2, 6) in slope-intercept form? Enter your answer by filling in the boxes to complete the equation.
Answer:
y = -5/2x +1
Step-by-step explanation:
You want the slope-intercept form equation for the line through the point (-2, 6) that is parallel to 5x +2y = -4.
Parallel lineThe equation of a parallel line can be the same as the given equation, except for the constant. The new constant can be found by substituting the given point coordinates:
5(-2) +2(6) = c
-10 +12 = c
2 = c
Now we know the equation of the parallel line can be written as ...
5x +2y = 2
Slope-intercept formSolving for y puts this in slope-intercept form:
2y = -5x +2 . . . . . . . . subtract 5x
y = -5/2x +1 . . . . . . . . divide by 2
We don't know what your boxes look like, but we can separate the numbers to make it look like this:
\(\boxed{y=\dfrac{-5}{2}x+1}\)

The 5th term of the arithmetic series is 1179/ 19.
How to solve an arithmetic series?The 10th term of the arithmetic series , S is 66.
Using arithmetic formula,
aₙ = a + (n - 1)d
where
n = number of termsd = common differencea = first termTherefore,
66 = a + 9d
The sum of the first 20 terms of S is 1290.
Therefore,
Sₙ = n / 2 (2a + (n - 1)d)
1290 = 10(2a + 19d)
1290 = 20a + 190d
combine the equation
66 = a + 9d
1290 = 20a + 190d
Hence,
a = 66 - 9d
1290 = 20(66 - 9d) + 190d
1290 = 1320 - 180 + 190d
1290 - 1320 + 180 = 190d
190d = 150
d = 150 / 190
d = 15 / 19
Hence,
a = 66 - 9(15 /19)
a = 66 - 135 / 19
a = 1254 - 135/ 19
a = 1119 / 19
Hence, let's find the fifth term.
a₅ = a + 4d
a₅ = 1119 / 19 + 4(15 / 19)
a₅ = 1119 / 19 + 60 / 19
Therefore,
a₅ = 1179/ 19

Two stockpots are similar cylinders. The smaller stockpot has a height of 10 inches and a radius of 2.5 inches, the volume of larger one is 628.32 cubic inches.
We know that, to find volume:
Volume = π * \(r^2\) * h
For the smaller stockpot:
Radius (r) = 2.5 inches
Height (h) = 10 inches
Volume = π * (2.5)² * 10 ≈ 196.35 cubic inches
For the larger stockpot:
Radius (r) = 2.5 inches
Height (h) = 16 inches
Volume = π * (2.5)² * 16
≈ 628.32 cubic inches
Thus, the volume of larger one is 628.32 cubic inches.

A coat check service charges $2 for the first hour and $1 for each additional hour or fraction of an hour. Which point is NOT included in the graph of the step function?
There is no point that is NOT included in the graph of the step function.
The coat check service charges $2 for the first hour and $1 for each additional hour or fraction of an hour.
To determine the point that is NOT included in the graph of the step function, we need to consider the charging scheme and analyze the pattern of charges.
The step function can be represented as follows:
For the first hour, the charge is a flat rate of $2.
For each additional hour or fraction of an hour, the charge is $1.
Let's analyze the points included in the graph:
(1, 2): This point represents the charge for the first hour, which is $2.
Now, let's consider the additional hours:
2. (2, 3): This point represents the charge for 2 hours, which is $2 for the first hour and $1 for the additional hour.
(3, 4): This point represents the charge for 3 hours, which is $2 for the first hour and $2 for the additional 2 hours.
(4, 5): This point represents the charge for 4 hours, which is $2 for the first hour and $3 for the additional 3 hours.
Based on the charging scheme, we can observe a pattern where the charge increases by $1 for each additional hour or fraction of an hour.
Since the charging scheme allows for any additional hour or fraction of an hour, there is no specific point that is excluded from the graph. Any positive value of x greater than or equal to 1 will have a corresponding point on the graph.

Step-by-step explanation:
this is the easiest way to solve for percentage:
\(\frac{part}{whole} =\frac{part}{whole}\) Where all the percents (except 100) would go in part
and the whole number would go in whole
\(\frac{25}{100} =\frac{?}{24}\) Then multiply 24 × 25 ÷ 100 = 6
\(\frac{15}{100} =\frac{?}{60}\) Multiply 60 by 25 then divided by 100 = 9

The value of x unknown for the given shape with given measurements 131°, 122°, 125°, 148°, 107°, 126° is equal to 141°.
The attached figure is seven sided polygon.
Seven sided polygon is called Heptagon.

Measurements are,
131°, 122°, 125°, 148°, 107°, 126°
Measurement of seventh angle is unknown.
let the measure of seventh angle be x°
⇒ x° + 131° + 122° + 125° + 148° + 107° + 126° = 900°
⇒ x° + 759° = 900°
⇒ x° = 900° - 759°
⇒ x° = 141°
Therefore, the value of x for the given shape with measurements is equal to 141°.

Answer:
f'(1)=150ln(1.5)
Step-by-step explanation:
I'm not sure why you would need a table since the limit definition of a derivative (from what I'm remembering) gives you the exact formula anyway... so hopefully this at least helps point you in the right direction.
My work is in the attachment but I do want to address the elephant on the blackboard real quick.
You'll see that I got to the point where I isolated the h's and just stated the limit equaled the natural log of something out of nowhere. This is because, as far as I know, the way to show that is true is through the use of limits going to infinity. And I'm assuming that you haven't even begun to talk about infinite limits yet, so I'm gonna ask you to just trust that that is true. (Also the proof is a little long and could be a question on it's own tbh. There are actually other methods to take this derivative but they involve knowing other derivatives and that kinda spoils a question of this caliber.)

In a bag there are 3 red marbles, 2 yellow marbles, and 1 blue marble. What is the likelihood of a yellow marble being selected on the first draw?
likely
unlikely
even chance
certain
Therefore, it is not even chance, but it is also not very unlikely. It is moderately likely that a yellow marble will be selected on the first draw.
What is Probability?Probability is a branch of mathematics that deals with the study of random events and their likelihood of occurring. It is a measure of the likelihood or chance of an event happening. Probability is expressed as a number between 0 and 1, where 0 means the event is impossible, and 1 means the event is certain.
In other words, probability is a way of quantifying uncertainty. It is used in various fields, such as statistics, physics, finance, engineering, and more, to help make predictions and decisions based on uncertain information. Probability theory provides a set of rules and tools for analyzing and manipulating random variables and events, and for calculating the probability of complex events.
The likelihood of a yellow marble being selected on the first draw can be calculated by dividing the number of yellow marbles by the total number of marbles in the bag:
likelihood of selecting a yellow marble = number of yellow marbles / total number of marbles
So, in this case, the likelihood of selecting a yellow marble on the first draw is:
likelihood of selecting a yellow marble = 2 / (3 + 2 + 1) = 2/6 = 1/3

What are the points of the image of the line in Q4 after the dilation?
Note that the coordinates of the point A' after rotating 90 degrees clockwise about the point (0,1) are (3, -4). (Option B)
How is this so ?To rotate a point 90 degrees clockwise about a given point,we can follow these steps -
Translate the coordinates of the given point so that the center of rotation is at the origin. In this case,we subtract the coordinates of the center (0,1) from the coordinates of point A (5,4) to get (-5, 3).
Perform the rotation by swapping the x and y coordinates and changing the sign of the new x coordinate. In this case,we swap the x and y coordinates of (-5, 3) to get (3, -5).
Translate the coordinates back to their original position by adding the coordinates of the center (0,1) to the result from step 2. In this case, we add (0,1) to (3, -5) to get (3, -4).
Therefore, the coordinates of the point A' after rotating 90 degrees clockwise about the point (0,1) are (3, -4).
