One night a theater sold 524 movie tickets. An adult's ticket costs $6.50 and a child's ticket cost $3.50. In all, $2881 was taken in. How many of each kind of ticket were sold?
196 children's tickets and 328 adult tickets were sold.
What is a system of equations?
A finite set of equations for which common solutions are sought is referred to as a set of simultaneous equations, often known as a system of equations or an equation system.
Here, we have
Given: One night a theater sold 524 movie tickets. An adult's ticket costs $6.50 and a child's ticket cost $3.50. In all, $2881 was taken in.
Let the amount of the child's ticket be x
Let the amount of adults tickets be y
If the total number of tickets sold is 524 movie tickets, then;
x + y = 524
x = 524 - y...(1)
If an adult ticket cost $6.50 and a child’s ticket cost $3.5 with a total of $2881 in all, then;
3.5x + 6.5 y = 2881
35x + 65y = 28810 ...(2)
Substitute equation 1 into 2:
35x + 65y = 2881
35(542-y) + 65y = 28810
18970 - 35y + 65y = 28810
30y = 9840
y = 328
Put the value of y in equation (1) and we get
x = 524 - 328
x = 196
Hence, 196 children's tickets and 328 adult tickets were sold.

The average rate of change of the function f(x) over the interval [-2, -9] is -6.
What is the average rate of change of the function f(x)?To determine the average rate of change of the function f(x) over the interval [-2, -9], we need to find the slope of the secant line that connects the points (-2, f(-2)) and (-9, f(-9)).
We first find the values of f(-2) and f(-9):
f(-2) = (-2)² + 5(-2) + 14 = 4 - 10 + 14 = 8
f(-9) = (-9)² + 5(-9) + 14 = 81 - 45 + 14 = 50
So, the two points are (-2, 8) and (-9, 50).

Un vêtements qui coutait initialement 100€ a vu son prix diminuer de 30% une première fois puis une deuxième fois de 20%.Quel pourcentage de réduction correspond à ces deux baisses successives?
Step-by-step explanation:
La première baisse de prix est de 30%, ce qui signifie que le prix du vêtement est maintenant de 70% de son prix initial :
Prix après la première baisse = 100€ - (30% x 100€) = 70€
Ensuite, le prix est réduit à nouveau de 20%. Cela signifie que le prix final est de 80% du prix après la première baisse :
Prix après la deuxième baisse = 70€ - (20% x 70€) = 56€
Le pourcentage de réduction totale correspond donc à la différence entre le prix initial et le prix final, exprimé en pourcentage du prix initial :
Pourcentage de réduction totale = ((100€ - 56€) / 100€) x 100% = 44%
Le vêtement a donc subi une réduction de 44% au total après les deux baisses successives de prix.
An object 60m long is drawn using a scale of 1cm to 10m. What is the length on drawing?
Using strategy 1 (in your head), divide 60m by 10m to get 6, then multiply that number by one to get 6cm. the length on drawing is 6cm
Procedure 2 (proportions)
Create a proportion first.
We know that 1 cm equals 10 metres, so we place them on a fraction (the operation is unaffected by the denominator or numerator). However, we don't know how many cm equal 10m, so we make that into a variable, in this case x.
1cm x cm
——— ———
100m 60m
Go diagonally to where the variables have already been put in to solve a proportion. You are unable to calculate 60 metres and x centimetres because you are unsure of x. Yet you can travel 60m. Start by multiplying 1 by 30 to reach the number 60. The result of multiplying 60 by 10m is x. This will equal 6.
Thus, your response is 6.

There are plans to install underground pipeline from the lake to the water level in Apache Durham Park what is the approximate length of pipe needed to the nearest meter
To determine the approximate length of the underground pipeline needed from the lake to the water level in Apache Durham Park, we would know the distance between the lake and park, as well as the specific path that the pipeline would take from the lake to the park.
Define the term length?Length is a physical or conceptual measurement of the extent of something from one end to the other.
It refers to the distance between two points or the size of an object or entity in the direction of its longest dimension. In mathematics and geometry, length is a fundamental concept used to describe the size and shape of geometric figures and objects.
It is measured in units such as meters, feet, inches, or centimeters
Assuming that we have this information, we can use the distance between the two points as the approximate length of the pipeline. To calculate this distance, we can use the distance formula:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
where (x1, y1) represents the coordinates of the lake and (x2, y2) represents the coordinates of Apache Durham Park.
Once we have the distance between the two points, we can round it to the nearest meter to get the approximate length of the pipeline needed.

the relationship between the diameter of the pizza and its cost per square inch is non-proportional.
The relationship between the diameter of the pizza and its cost per square inch is non-proportional.
If the relationship were proportional, then the cost per square inch of the pizza would remain constant as the diameter changes. However, in this case, we see that as the diameter of the pizza increases, the cost per square inch decreases. This is because the area of a circle increases more rapidly than its diameter, so the cost must be spread out over a larger area, resulting in a lower cost per square inch.
Therefore, the relationship between the diameter of the pizza and its cost per square inch is non-proportional.

A rope is swinging in such a way that the length of the arc is decreasing geometrically. If the the first arc is 18 feet long and the third arc is 8 feet long, what is the length of the second arc?
Explain step by step.
Geometric Sequence:
In mathematics, a sequence in which each number is multiplied by its previous term is called a geometric sequence.
The standard form of the geometric sequence is:
an=a1×rn−1Where, r = Common ratio a1= First term an=n th term
The length of the second arc is 8 feet.
The rope is swinging in such a way that the length of the arc is decreasing geometrically.
If the first arc is 18 feet long and the third arc is 8 feet long,
The length of the second arc :
In order to find the second arc length, we need to use the formula of the geometric sequence.
We have to understand what is given and what is required.
Given : First arc = 18 feet
Third arc = 8 feet.
To Find : Length of the second arc.
The formula of the geometric sequence is :
[tex]a_n[/tex] = [tex]a_1[/tex] × rn − 1
where, r = Common ratio [tex]a_1[/tex] = First term [tex]a_n[/tex] = [tex]n^{th}[/tex] term
Here, the length of the first arc is [tex]a_1[/tex] = 18.
The length of the third arc is [tex]a_3[/tex] = 8.
We have to find the length of the second arc, which is [tex]a_2[/tex]
Using the formula of the geometric sequence, we can find the [tex]a_1[/tex]: r= [tex]a_3[/tex] / [tex]a_2[/tex]
We know that [tex]a_1[/tex]= 18 and [tex]a_3[/tex]= 8
Substitute the values: r= 8 / [tex]a_2[/tex]
Now, we can rewrite the formula of the geometric sequence: an=[tex]a_1[/tex]×rn−1an= [tex]a_1[/tex] x r(n-1)
The length of the first arc is [tex]a_1[/tex] = 18 feet.
Substituting the value of r, we get:
8 / [tex]a_2[/tex] = r18 x r(n-1) = [tex]a_2[/tex]
We are given that the length of the third arc is 8 feet,
thus : 8 = 18 x r(3-1)8
= 18 x [tex]r_2[/tex][tex]r_2[/tex]
= 8 / 18[tex]r_2[/tex]
= 4 / 9r
= √(4/9)
Using this value of r, we can find the length of the second arc :
[tex]a_2[/tex] = 18 x (4/9) (2-1) [tex]a_2[/tex]
= 18 x (4/9)[tex]a_2[/tex]

what enone product would you expect to obtain from intramolecular aldol condensation of 3-methylheptane dial?
The expected product from the intramolecular aldol condensation of 3-methylheptane dial is a cyclic α,β-unsaturated ketone with a seven-membered ring.
3-methylheptane dial is a 7-carbon compound with two carbonyl groups, one at each end of the molecule. Intramolecular aldol condensation occurs when one carbonyl group reacts with the other within the same molecule. The carbonyl group acts as an electrophile, while the enolate formed from the other carbonyl group acts as a nucleophile.
In the case of 3-methylheptane dial, intramolecular aldol condensation can occur between the carbonyl group at the 3-position and the enolate formed from the carbonyl group at the 6-position. The resulting intermediate undergoes dehydration to form a cyclic α,β-unsaturated ketone.
The product of the reaction will have a cyclic structure with a double bond between the α and β carbons. The exact structure of the product will depend on the stereochemistry of the starting material and the reaction conditions. However, the product is expected to have a seven-membered ring and to be an α,β-unsaturated ketone.

A banner is centered between two poles by four ropes of equal length. The dimensions of the banner ground and poles are shown what is the length of one of the ropes x to the nearest foot
The length of one of the ropes is approximately 10.77 feet when rounded to the nearest foot.
Let's call the distance between the poles "d" and the height of the poles "h". We can use the Pythagorean theorem to find the length of the ropes:
If we draw a diagram, we can see that the four ropes form the hypotenuses of four right triangles. Each right triangle has a base of d/2 and a height of h - (banner height)/2.
Therefore, we have:
[tex]x^2[/tex] = [tex](d/2)^2[/tex] + [tex](h - (banner height)/2)^2[/tex]
Substituting the given values, we get:
[tex]x^{2}[/tex] = [tex](20/2)^2[/tex]+ [tex](16 - (8/2))/2)^2[/tex]
[tex]x^{2}[/tex]= 100 + [tex](8/2)^2[/tex]
[tex]x^{2}[/tex] = 100 + 16
[tex]x^{2}[/tex] = 116
Taking the square root of both sides, we get:

The two shorter sides of an right triangle measure 15 inches and 3 feet. What is the length of the longest side?
The two shorter sides of a right triangle measure 15 inches and 3 feet and the length of the longest side also known as the hypotenuse is 3.269557 feet.
It is given to us that the two shorter sides of a right triangle measure 15 inches and 3 feet.
Let us say that side a is 3 feet and side b is 15 inches and we need to find side c, that is the longest side also known as the hypotenuse,
A right-angled triangle is one in which only one angle is precisely 90 degrees. Since the total of all the angles in a triangle is always 180°, the other two angles will be obviously smaller than the right angle.
We define the sides of a right-angled triangle in a unique manner. The hypotenuse of a triangle is the edge that faces the right angle and is always the largest.
Pythagorean formula. Pythagoras' theorem says that: a² + b² = c². in a right triangle with cathetus a and b and with hypotenuse c.
Take the square root of both sides to find c = √(b²+a²). This Pythagorean theorem expansion can be thought of as a "hypotenuse formula."
Therefore, with this formula we can solve for hypotenuse:
side a = 15 inches = 1.3 feet
side b = 3 feet
a² + b² = c²
1.3² + 3² = c²
1.69 + 9 = c²
10.69 = c²
c = 3.269557 feet
Therefore, we can say that the two shorter sides of a right triangle measure 15 inches and 3 feet and the length of the longest side also known as the hypotenuse is 3.269557 feet.

The hour hand of a clock is 4.5 cm long while the minute hand of clock is 5.5 cm long (Take # 3.14) What distance does the tip of the hour hand cover in twelve hours (b) What distance does the tip of the minute hand cover in one (c) Which tip covers a longer distance in (a) and (b) above and by how much
(a) The distance that the tip of the hour hand covers in twelve hours is 28.29 cm.
(b)The distance that the tip of the minute hand covers in one hour is 34.57 cm.
(c) The tip of the minute hand covers a longer distance than the tip of the hour hand by 6.28 cm.
How to find the distance the tip of the hour hand cover in twelve hours?(a) To find the distance that the tip of the hour hand covers in twelve hours, we need to calculate the circumference of the circle that the tip of the hour hand traces in twelve hours. The circumference is given by:
C = 2πr
where r is the length of the hour hand
C = 2 x 22/7 x 4.5
C = 28.29 cm
(b) Also, the distance that the tip of the minute hand covers in one hour is:
C = 2 x 22/7 x 5.5
C = 34.57 cm
(c) We can see that the distance covered by the minute hand in one hour (34.57 cm) is greater than the distance covered by the hour hand in twelve hours (28.29 cm).
difference = 34.57 cm - 28.29 cm = 6.28 cm
Thus, the tip of the minute hand covers a longer distance than the tip of the hour hand by 6.28 cm.

What property is being used in the following:
5/6 + 7/12 = 7/12 + 5/6
Answer:
Commutative property of addition
Step-by-step explanation:
The property being used in this equation is the commutative property of addition. This property states that when two numbers are added, the order in which they are added does not change the sum. So, in this case, we can rearrange the terms 5/6 and 7/12 and still get the same result.

Suppose that the functions q and r are defined as follows. Find the following
The value of the function q and r are as follows (q ° r )(7) = 22 and (r ° q)(7) = 8.
What are composite functions?The process of integrating two or more functions into one function is known as composition of functions. A function is an example of labour. Take making bread as an example. Let x be the flour, let g(x) be the function that the food processor performs to prepare the dough using the flour, and let f(x) be the function that the oven does to bake the bread. The output of g(x) should be sent into the function f(x) to make bread (i.e., the prepared dough should be placed in the oven). The outcome is represented by the symbol f(g(x)), and it is made up of the functions f(x) and g. (x).
The function q and r are as follows:
q(x) = x² + 6
r(x) = √(x + 9)
The value of:
(q ° r )(x) = q(r(x))
Here, substitute the value of x in q(x) with the value of r(x):
q(r(x)) = (√(x + 9))² + 6
q(r(x)) = x + 9 + 6
Substitute x = 7:
q(r(7)) = 7 + 9 + 6 = 22
Now, (r ° q) = r(q(x))
r(q(x)) = √(x² + 6 + 9)
= √(x² + 15)
Substitute x = 7:
r(q(7)) = √(7² + 15) = √(49 + 15) = √64 = 8
Hence, the value of the function q and r are as follows (q ° r )(7) = 22 and (r ° q)(7) = 8.
