By solving a system of equations we can see that there are 400 main-floor seats and 200 balcony seats.
Let x = number of seats on the main-floor
y = number of balcony seats
We know that if all the seats are sold, then the total income is $4,200, we can write the equation:
x*8 + y*5 = $4,200
And if 25% of the main-floor and 40% of the balcony seats are sold, then we get an income of $1200, then we can write:
0.25*x*8 + 0.4*y*5 = $1,200
x*2 + y*2 = $1,200
2(x + y) = $1200
x + y = $600
x = 600 - y
putting the value of x in equation1)
8(600-y) + 5y = 4200
4800 - 8y + 5y = 4200
3y = 600
y = 200
and x = 600 - 200 = 400

What is cross multiplication?A method for finding the answer to linear equations in two variables is cross-multiplication. It turns out to be the quickest way to resolve two linear equations. To cross multiply two fractions, multiply the first fraction's numerator by the second's denominator and the second fraction's numerator by the first fraction's denominator.
Given that, distance between Dallas and Houston is about 364 kilometers.
The measurement of:
8 km = 5 miles
364 km = x miles
Using the method of cross multiplication, we have:
x = 364 (5) / 8
x = 227.5 miles
Hence, the measurement closest to the number of miles between the two towns is 227.5 miles.

Sophia brought some almonds from the store. She handed the cashier $15 and received $5 in change. Mr. Boone is buying an app for the class. The app costs a dollars per student and he has 32 students. He spends $96. How much is the app per student?
The cost per student for the app is $3, and can be found by dividing the total cost of $96 by the number of students, 32, which equals $3 per student.
Let x be the cost of the almonds Sophia bought and y be the cost of the app per student. Then, we have the subsequent two equations:
x + $5 = $15
32y = $96
To find the cost of the app per student, we can solve for y in the second equation:
y = $96 / 32 = $3
So the app costs $3 per student.
To find the cost of the app per student, we need to find the total cost of the app and then divide it by the number of students. Mr. Boone spent $96 on the app for 32 students, so the cost per student would be $96 / 32 = $3. This means that each student paid $3 for the app.

A father age is 25 years older than Son the sum of Their age is 53. find their Ages using simul- taneous equation and using elimination method
Answer: To find the father's and son's ages, we can set up two simultaneous equations:
Let's say the son's age is "x"
Then, the father's age would be x + 25
And the sum of their ages is x + (x + 25) = 53
So, 2x + 25 = 53
Solving for x, we get:
2x = 28
x = 14
Therefore, the son is 14 years old, and the father is 14 + 25 = 39 years old.
To use the elimination method, we can add the two equations:
x + (x + 25) = 53
2x + 25 = 53
Simplifying, we get:
2x = 28
x = 14
And the father's age would be x + 25 = 14 + 25 = 39 years old.

Prove by induction that if we remove the root of a k-th order binomial tree, it results in k binomial trees of the smaller orders. You can only use the definition of Bk. Per the definition, Bk is formed by joining two Bk−1 trees.
We will prove that if we remove the root of a k-th order binomial tree, it results in k binomial trees of smaller orders.
Base case: If k = 1, the binomial tree consists of a single node. Removing the root node leaves an empty tree, which can be considered as a collection of 0 binomial trees of smaller orders.
Induction hypothesis: Assume that the statement is true for a k-th order binomial tree.
Induction step: We need to prove that the statement is true for a (k+1)-th order binomial tree, which is formed by joining two k-th order binomial trees.
Remove the root node of the (k+1)-th order binomial tree. This results in two trees, each of which is a k-th order binomial tree.
By the induction hypothesis, removing the root node of each of the two k-th order binomial trees results in k binomial trees of smaller orders.
Thus, removing the root node of the (k+1)-th order binomial tree results in a total of 2k binomial trees of smaller orders, which completes the proof.

The average speed of Paul Revere's horse, assuming he rode straight to Lexington without stopping, would have been approximately 25.4 miles per hour.
To find the average speed of Paul Revere's horse, we can use the formula:
average speed = total distance / total time
In this case, the total distance is 11 miles, and the total time is 26 minutes, or 0.4333 hours (since there are 60 minutes in an hour).
So, the average speed of Paul Revere's horse would be:
average speed = 11 miles / 0.4333 hours
average speed ≈ 25.4 miles per hour
Therefore, the average speed of Paul Revere's horse, to the nearest tenth of a mile per hour, would have been 25.4 miles per hour.
Using the formula for average speed, we can calculate that Paul Revere's horse would have had to travel at an average speed of approximately 25.4 miles per hour to cover the 11-mile distance in 26 minutes. This assumes that he rode straight through without stopping.

How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,

By using shipping volume, Packing Group B needs to process 168,000 units in order to ship a total of 168,000 units for the shift.
To solve this problem, we need to work backwards from the shipping volume and use the given processing rates to determine the required processing volumes for each stage of the process.
First, we can calculate the total number of hours of packing and shipping required to process 168,000 units:
168,000 units ÷ 175 units per person per hour = 960 hours
Next, we can determine the volume of items that need to be packed by Group B in order to ship this total volume. Since Group B processes 65% of the volume, we can set up the following equation:
0.65x = 168,000 units
where x is the total volume of items processed by all packing groups. Solving for x, we get:
x = 168,000 units ÷ 0.65 = 258,461.54 units
So the total volume of items processed by all packing groups is approximately 258,461.54 units. We can now use the given processing rates to determine the required processing volumes for each stage:
Picking: 100% of 258,461.54 units = 258,461.54 units
Packing Group A: 35% of 258,461.54 units = 90,461.54 units
Packing Group B: 65% of 258,461.54 units = 168,000 units
Therefore, Packing Group B needs to process 168,000 units in order to ship a total of 168,000 units for the shift. The answer is 168,000.

The Linear Equation for the line with slope as -1/3 and the point (-9,-1) is y = (-1/3)x - 4 .
We use the point slope form of a linear equation to write the equation of a line with its slope and a point on the line.
The point-slope form is ⇒ y - y₁ = m(x - x₁) ;
Where m is = slope of line, and (x₁, y₁) is a point on line.
The Slope (m) of line is = -1/3 and point on line (x₁, y₁) is = (-9, -1),
Now , we substitute these values ;
we get ;
⇒ y - (-1) = (-1/3)(x - (-9)) ;
⇒ y + 1 = (-1/3)(x + 9) ;
Simplifying further ,
we get ;
⇒ y + 1 = (-1/3)x - 9/3 ;
Subtracting 1 from both sides, we get:
