Answers
The required number of children and adults for sitting in the theater are 300 and 50 respectively.
Explain linear equation of two variable.A equation is supposed to be linear equation in two factors in the event that it is written as hatchet + by + c=0, where a, b and c are genuine numbers and the coefficients of x and y, i.e an a and b separately, are not equivalent to nothing. For instance, 10x+4y = 3 and - x+5y = 2 are straight equation in two factors.
According to question:Let be consider number of children be x and that of adults is y.
We have,
x + y = 350-------(1)
y = 350 - x
And 5x + 10y = 2000------------------(2)
Put value of y in equation (2)
5x + 10( 350 - x) = 2000
5x + 3500 - 10x = 2000
-5x = -1500
x = 300
Then
y = 350 - x = 350 - 300 = 50
Thus, There will be 300 children and 50 adults in the theater .

Answers
The given equation is equivalent to the system
\(\begin{cases}y = 17x-8\\y = 3x+16\end{cases}\)
The linear equations have different slopes (m = 17 and m = 3), so that means the two lines intersect at exactly one location. This one intersection point means there is exactly one solution to the system.
That means there is exactly one solution to the equation 17x-8 = 3x+16

Solve a System of Linear Equations by Graphing
In this chapter we will use three methods to solve a system of linear equations. The first method we’ll use is graphing. The graph of a linear equation is a line. Each point on the line is a solution to the equation. For a system of two equations, we will graph two lines. Then we can see all the points that are solutions to each equation. And, by finding what the lines have in common, we’ll find the solution to the system.
Most linear equations in one variable have one solution, but we saw that some equations, called contradictions, have no solutions and for other equations, called identities, all numbers are solutions. Similarly, when we solve a system of two linear equations represented by a graph of two lines in the same plane, there are three possible cases, as shown in Figure 5.1.1 :
This figure shows three x y-coordinate planes. The first plane shows two lines which intersect at one point. Under the graph it says, “The lines intersect. Intersecting lines have one point in common. There is one solution to this system.” The second x y-coordinate plane shows two parallel lines. Under the graph it says, “The lines are parallel. Parallel lines have no points in common. There is no solution to this system.” The third x y-coordinate plane shows one line. Under the graph it says, “Both equations give the same line. Because we have just one line, there are infinitely many solutions.”
Figure 5.1.1
For the first example of solving a system of linear equations in this section and in the next two sections, we will solve the same system of two linear equations. But we’ll use a different method in each section. After seeing the third method, you’ll decide which method was the most convenient way to solve this system.

The government sees your egg apparatus and decides to use it as a model to create structures to protect food that is dropped over areas for disaster relief. if eggs are typically 2.5 ounces and there are 16 ounces in a pound and a bag of rice is 65 pounds, assuming the size of the rice apparatus is directly proportional to the egg apparatus, how much bigger does the rice apparatus need to be?
Answers
We are given that an egg weighs 2.5 ounces and that there are 16 ounces in a pound. We also know that the rice apparatus is directly proportional to the egg apparatus. The rice apparatus needs to be the same weight and size as the egg apparatus.
To find out how much bigger the rice apparatus needs to be, we need to determine the weight of the rice apparatus. First, we calculate the weight of the bag of rice by multiplying the weight of a pound (16 ounces) by the number of pounds (65 pounds). This gives us 1040 ounces (16 * 65).
Next, we need to determine the ratio between the egg apparatus and the rice apparatus. Since they are directly proportional, we can set up a proportion using their weights:
(egg weight) / (rice weight) = (egg size) / (rice size)
Substituting the values we have, we get:
2.5 / (rice weight) = 2.5 / (1040)
Now, we can solve for the weight of the rice apparatus:
(rice weight) = (2.5 * 1040) / 2.5
Simplifying, we find:
(rice weight) = 1040
Therefore, the weight of the rice apparatus needs to be the same as the weight of the bag of rice, which is 1040 ounces.
In terms of size, since the weight of the rice apparatus is directly proportional to the egg apparatus, we can conclude that the rice apparatus needs to be the same size as the egg apparatus.
In summary, the rice apparatus needs to be the same weight and size as the egg apparatus.

How many nonzero terms of the Maclaurin series for In (1+x) do you need to use to estimate In(1.4) to within 0.00001 ?
Answers
Need at least n = 4 nonzero terms in the Maclaurin series to estimate ln(1.4) within 0.00001.To estimate ln(1.4) to within 0.00001 using the Maclaurin series for ln(1+x), we need to determine the number of nonzero terms required.
The Maclaurin series for ln(1+x) is given by:
ln(1+x) = x - (x^2)/2 + (x^3)/3 - (x^4)/4 + ...
We want to find the number of terms, denoted as n, such that the remainder term R_n is less than 0.00001. The remainder term can be expressed as:
R_n = |(x^(n+1))/(n+1)|
We can solve for n by substituting x = 0.4 (since 1.4 - 1 = 0.4) and setting R_n < 0.00001:
|(0.4^(n+1))/(n+1)| < 0.00001
Since the term (0.4^(n+1))/(n+1) is always positive, we can remove the absolute value signs:
(0.4^(n+1))/(n+1) < 0.00001
To solve this inequality, we can start by trying different values of n until we find the smallest n that satisfies the inequality.
Using a trial-and-error approach:
For n = 4: (0.4^5)/5 ≈ 0.00008192 (satisfied)
For n = 3: (0.4^4)/4 ≈ 0.0004096 (satisfied)
For n = 2: (0.4^3)/3 ≈ 0.002133333 (not satisfied)
Therefore, we need at least n = 4 nonzero terms in the Maclaurin series to estimate ln(1.4) within 0.00001.

Step-by-step explanation:
The slope of the function is given by the slope formula ...
m = (y2 -y1)/(x2 -x1)
The y-intercept (b) can be found from the table when it includes a point (x, y) = (0, b). If the table doesn't have the y-intercept, it can be found from ...
b = y -mx
When m and b are known, the slope-intercept equation is ...
f(x) = mx +b

19.m = (11 -14)/(-2 -(-3)) = -3/1 = -3
The slope is -3. The function is f(x) = -3x +5.
__
21.m = (9 -9)/(2 -3) = 0/-1 = 0
The slope is 0. The function is f(x) = 9.

A bakery sold a total of 200 cupcakes in a day, and 42 of them were chocolate flavored. What percentage of cupcakes sold that day were chocolate flavored?.
Answers
Percentage of cupcakes which was chocolate flavored = 21%. The formula to calculate percentage is (x/100 * total number of items = given no of items).
Let x be the percentage of chocolate flavored cupcakes
Therefore,
x% of 200 = 42
Since the total no. of cupcakes is 20.
=> x/100 * 200 = 42
=> x * 2 = 42
=> x =21
Hence the required percentage is 21 %.
A % is a number without dimensions. It is a ratio or a number that is written as a fraction of one hundred. The percentage sign (%) is the symbol used to represent a percentage.

The statement that is always true in parallelogram QRST with diagonals QS and RT intersecting at point E is ZTQS = ZQST.
The question is about a parallelogram QRST and its diagonals QS and RT intersecting at point E.
To determine which statement is always true, we need to use the properties of parallelograms and diagonals.
Statement 1: QS I RT - This statement is not always true. It is true for a parallelogram, but not necessarily for a general quadrilateral.
Statement 2: QT = RS - This statement is not always true. It is true only for a parallelogram where opposite sides are congruent.
Statement 3: AQSR = AQST - This statement is not always true. It is true only for a parallelogram where opposite angles are congruent.
Statement 4: ZTQS = ZQST - This statement is always true. When the diagonals of a parallelogram intersect, they bisect each other. This means that angle ZTQ is congruent to angle ZQS, and angle ZQT is congruent to angle ZST. Therefore, angle ZTQS is congruent to angle ZQST.

Answers
A function object is a value that can be assigned to a variable or passed as an argument. For example, the "do_twice" function is a function that takes a function object as an argument and calls it twice.
In Python, functions are first-class objects, which means they can be treated just like any other value. This allows us to assign functions to variables, pass them as arguments to other functions, and even return them from other functions.
Here's an example of the "do_twice" function in Python:
def do_twice(func):
func() # Call the function object the first time
func() # Call the function object the second time
def say_hello():
print("Hello!")
do_twice(say_hello) # Output: "Hello!" twice
In this example, the "do_twice" function takes a function object, func, as its argument. It then calls the func twice by invoking it as func(). The say_hello function is defined separately and passed as an argument to do_twice. When do_twice is called with say_hello, it executes say_hello two times, resulting in the output "Hello!" printed twice.
A function object in Python is a value that can be assigned to variables or passed as arguments to other functions. The ability to treat functions as first-class objects allows for flexible and powerful programming techniques, such as higher-order functions and function composition.

(145.98 x 9) + (129.45 x 4) = ?
145.98 multiplied by 9 is 1313.82
1313.82 + (129.45 x 4) = ?
129.45 multiplied by 4 is 517.8
1313.82 + 517.8 =
1831.62
I hope this helps :)
