Answer:
a=100, c=44
Step-by-step explanation:
# of adult tickets is represented by a
# of child tickets is represented by c
C+A=144
9a+6c=1164
system of equations is solved by solving 1 equation for 1 variable first.
c=144-a
plug in c in the second equation
9a+6(144-a)=1164
9a+864-6a=1164
combine like terms
3a=300
a=300/3
a=100
now we know a is 100 we can plug it into the original equation of c=a=144
c+100=144
c=144-100
c=44
A corporation earned a profit of $2. 5 x 10 to the 4th power for 1 x 10 to the 3rd power days in a row. What was the corporation's total profit during this time period?
Answer in both scientific notation and standard form
The overall profit of the corporation as during time period is $ 2.5 x 10⁷
Define the term scientific notation?Scientific Notation (also known as Standard Form) is a process of presenting numbers in a concise manner. A number expressed in Scientific Notation is a number between 1 and less than 10, scaled by such a power of ten. Move this decimal point such that there one digit (that cannot be zero) before it.As the question expressed-
Earned profit - $2. 5 x 10 to the 4th power
In scientific notation - $2. 5 x 10⁴
Number of days - 1 x 10 to the 3rd power
In scientific notation - 1.0 x 10³
Total profit = Earned profit x Number of days
Total profit = $2. 5 x 10⁴ x 1.0 x 10³
Total profit = $ 2.5 x 10⁷
Thus, the overall profit of the corporation as during time period is $ 2.5 x 10⁷.

The coordinates of each image are G'(-2,9), and H'(1,-3).
What are the coordinates?
A pair of numbers that use the horizontal and vertical separations from the two reference axes to define a point's location on a coordinate plane. typically expressed by the x-value and y-value pair (x,y).
Here, we have

Alicia wants the arrangement to have twice as many flowers as twigs. Write and solve a system of equations to find the number of twigs and flowers that Alicia will need.
By solving a system of two simultaneous linear equations, it can be calculated that
Alicia will need 3 twigs and 6 flowers
What is simultaneous linear equation?
At first it is important to know about linear equation
Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.
A one degree equation is known as linear equation.
Two or more linear equations, which can be solved together to obtain common solution are known as simultaneous linear equation.
Here, a system of two simultaneous linear equation needs to be solved
Let the number of twigs Alicia needed be x and the number of flowers Alicia needed be y
Alicia has to create an arrangement of twigs and flowers that has a total of 9 objects.
x + y = 9 ..... (1)
Alicia wants the arrangement to have twice as many flowers as twigs
2x = y .... (2)

Based on the information provided, ETS is an abbreviation for these three terms (Error, Trend, and Season). Following that, Exponential Smoothing Methods for an ETS system can be described, with the details specified in a smoothing style.
=> As should be obvious, combining Error, Trend, and Season on any occasion in three distinct ways yields a plethora of combinations.
=> The trend depicts the overall layout of the time. It communicates with the data's drawn-out model — its tendency.
=> The seasonal section displays the types associated with anticipated events. Finally, the error component explains what the season and trend components do not. The error is due to the disparity between the first data and the combination of trend and seasonality. As a result, if we crystallize all three parts, we will have the first data back.

The number of ride tickets that were sold are 8 and the number of food tickets that were sold are 24 .
In the question ,
it is given that
total number of tickets bought by the family at carnival = 32 tickets
total amount spent by the family of tickets = $90
let the number of ride tickets be [tex]=[/tex] x
let the number of food tickets be [tex]=[/tex] y
So , x + y = 32
x = 32 - y
cost of 1 ride ticket = $1.50
cost of 1 food ticket = $3.25
So the total cost is 1.25x + 3.25y = 90
Substituting x = 32 - y in the equation 1.5x + 3.25y = 90 ,
we get ,
1.5(32 - y) + 3.25y = 90
48 - 1.50y + 3.25y = 90
1.75y = 90 - 48
1.75y = 42
y = 24
So , x = 32 - 24 = 8

What is probability?The probability is the likelihood that something will happen, to put it simply. When we don't know how something will turn out, we can talk about the possibility of one outcome or the likelihood of several. The study of events that fit into a probability distribution is known as statistics. Probability is a branch of mathematics that deals with numerical representations of the likelihood of an event occurring or of a proposition being true.So, the probability that we will see at least 2 meteors in the first minute:

How to determine the equation of the graph?The graph represents the given parameter
From the graph, we have the following highlights:
The graph is an absolute value graphThe graph has its minimum point at (3, 5)This means that
Vertex = (3, 5)
Rewrite the vertex as
(h, k)
An absolute value function is represented as
f(x) = a|x - h| + k
Substitute the known values in the above equation
So, we have the following equation
f(x) = a|x - 3| + 5
On the graph, we have
(x, f(x)) = (2, 6)
So, we have
6 = a|2 - 3| + 5
This gives
a = 1
So, we have
f(x) = 1 * |x - 3| + 5

Consider a window the shape of which is a rectangle of height h surmounted by a triangle having a height t that is 0.9 times the width w of the rectangle. if the cross-sectional area is a, determine the dimensions of the window which minimize the perimeter.
The cross-sectional area is (h × w ) + ((1 ÷ 2) × 0.9 × w²) and the dimensions of the window which minimize the perimeter is (A - [tex]c_{0}[/tex][tex]w_{0}^{2}[/tex]) ÷ [tex]w_{0}[/tex] = 2√A[tex]c_{1}[/tex]([tex]c_{2}[/tex] - [tex]c_{0}c_1[/tex]) = 0.60592√A.
height of rectangle = h
height of the triangle = t
T = 0.9
width of the rectangle = w
The formula of Cross-sectional area is,
A = h × w + (1 ÷ 2)T × w
A = (h × w ) + ((1 ÷ 2) × 0.9 × w²)
Perimeter,
P = w + (2 × h) + 2√(T² + (w ÷ 2)²)
P = w + (2 × h) + 2√((0.9)² + (1 ÷ 2)²)
P = 2h + 2√((0.9)² + (1 ÷ 2)² + 1) × w
Therefore, [tex]C_{0}[/tex] = 0.9 ÷ 2, [tex]C_{1}[/tex] = 2, [tex]C_{2}[/tex] = 2√((0.9)² + (1 ÷ 2)² + 1)
minP=[tex]c_1[/tex]h+[tex]c_2[/tex]w
A = (h × w) + [tex]c_{0}[/tex]w²
substituting h = (A - [tex]c_{0}[/tex]w²) ÷ hw in P,
P = [tex]c_1[/tex]w + ([tex]c_1[/tex](A - [tex]c_{0}[/tex]w²) ÷ w)
Differentiating both sides,

[tex]w_{0}[/tex] = (√[tex]c_{1}[/tex]A ÷ (√[tex]c_{2}[/tex] - [tex]c_{0}c_1[/tex])) = 0.962445√A

[tex]h_{0}[/tex] = (A - [tex]c_{0}[/tex][tex]w_{0}^{2}[/tex]) ÷ [tex]w_{0}[/tex] = 2√A[tex]c_{1}[/tex]([tex]c_{2}[/tex] - [tex]c_{0}c_1[/tex]) = 0.60592√A
