Answer:
No. of ticket bought is 4
Step-by-step explanation:
Let the no. of ticket bought be x
Given cost of 1 ticket = $12
Therefore cost x ticket = x*cost of 1 ticket = x*$12 = $12x
parking fee = $5
given that it is flat so, whatever be the no. of ticket bought or family member,
the parking cost will remain $5 only.
Total money paid by family = parking charge + cost x ticket = 5+12x
But , given that family paid total of $53
then
5 + 12x = 53
=> 12x = 53-5 = 48
=> x = 48/12 = 4
Thus, no. of ticket bought is 4.
This can be validated as shown below
cost of 4 ticket as 12 each will be = 12*4 = 48
thus total money paid = $(48+5 )= $53

Cesar comenta que su papa esta interesado en comprar un terreno o vivienda.En estos tiempos de cuarentena su padre ha aprendido a comunicarse mas por medio de las redes sociales y justamente,atraves de whappsap,un amigo le envio una imagen del terreno de una vivienda en venta. Su padre le mostro la imagen y quiere que le alyude a realizar diversos calculos.si los calculos son 40m+14m+a+20m+54m+20+a.¿cual es el area de la vivienda?
Answer:
El área de la casa es de 1,304 m²
Step-by-step explanation:
De las dimensiones dadas en línea, tenemos que el área del jardín = 640 m²
Las dimensiones del jardín son;
Longitud = 40 m.
Ancho = a m
Por lo tanto, 40 × a = 640
a = 640/40 = 16 m
La dimensión del compuesto es así;
Longitud = 40 + 14 = 54 m
Ancho = 20 + a = 20 + 16 = 36 m
El área del compuesto = Área de la casa + Área del jardín
El área del compuesto = Ancho del compuesto × Longitud del compuesto
El área del compuesto = 36 × 54 = 1,944 m²
∴ 1,944 m² = Área de la casa + Área del jardín
1,944 m² = Área de la casa + 640 m²
Área de la casa = 1,944 m² - 640 m² = 1,304 m²
El área de la casa = 1,304 m².
Which graph represents a function?
2
1
23
23
2 3 4 5
Answer:
D, the graph in the bottom row, on the right side
Step-by-step explanation:
A function will not have repeating x values, and the graph on the bottom right is the only that passes the vertical line test(meaning there are no repeating x values).
Answer:
The fourth option
Step-by-step explanation:
Remember a function is a line that only gets intersected once, in this case it's not option one because the graph gets intersected twice. It's not option two because the lines also get intersected twice, it's not option three because it doesn't intersect the line at all which gives you the fourth option which intersects the line once making it a function.

On a nearby pond, black and white ducks are swimming in groups of 3. James wants to find the experimental probability of two white ducks and one black duck swimming together. Design a simulation using a coin flip and explain why it is the best choice for James.U Will get BRAINLIEST
Answer:
The answer is below
Step-by-step explanation:
Given that, there are only two available choices, which are a black or white duck, this can be represented using a coin: H→White duck, T→Black Duck
Hence, to represent a set of possible outcomes, the coin has to be tossed three times.
Thus, we assume that, at the minimum we have total number of Ducks = 3 Black + 3 White = 6 Ducks
Total Favorable Outcome = 2 White + 1 Black
Total Possible Outcome = Selecting 3 Ducks (2 White +1 Black) from 6 Ducks
Formula to Calculate Probability
= Total favourable outcome ÷ Total possible outcome
Use ,C(n,r)= n! / (n - r)! r!
Therefore, the Probability of two white ducks one black duck swimming together
= ³C² * ³C¹ ÷ 6C3 = 9/20
To use Simulation Coin Flip, we have the following:
H→White duck, T→Black Duck
HHH→Three White Ducks Swimming together
TTT→Three black ducks Swimming together
HHT→Two white duck and a Black Duck swimming together
HTH→Two white duck and a Black Duck swimming together
THH→Two white duck and a Black Duck swimming together
TTH→Two Black duck and a White Duck swimming together
THT→Two Black duck and a White Duck swimming together
HTT→Two Black duck and a White Duck swimming together
Finally, to find the probability, divide the observed desired outcomes by the total number of trials.
Answer:
There are only two choices, a black or white duck, so a coin is the best choice. To represent a set of possible outcomes, toss the coin three times. Repeat the experiment multiple times. To find the probability, divide the observed desired outcomes by the total number of trials.

So,
y = e^2x - 4
Now
Replace x and y
Therefore
x = e^2y - 4
Now compute the value of y
So,
x + 4 = e^2y
Now take ln on both sides:
The equation is
ln(x+4) = ln(e^2y)
ln(x+4) = 2y
y = ln(x+4) ÷ 2
[tex]f^{-1}(x)= \frac{ln\ x+4}{2}[/tex]
Therefore, To determine the inverse of the given function, change f(x) to y, switch x and y and solve for y and [tex]f^{-1}(x)= \frac{ln\ x+4}{2}[/tex]

Simplify: 0.9(3÷2.25− 1 8 (1 2 3 + 1 9 ))− 4 7 ÷0.8
Answer:
I'm not sure if it's right but I got -2455.15
Step-by-step explanation:
You would use PEMDAS,
( 129 + 19 ) = 148
-18 ( 148 ) = -2664
3/2.25 = 1.333333333
1.333333333 - 2664 = -2662.666667
0.9 ( -2662.666667 ) = -2396.4
-47/8 = -58.75
-2396.4 - 58.75 = -2455.15
The value of the given expression is -2357.953.
Given that, 0.9(3÷2.25− 1 8 (1 2 3 + 1 9 ))− 4 7 ÷0.8.
What is BODMAS rule?The Bodmas rule follows the order of the BODMAS acronym ie B – Brackets, O – Order of powers or roots, D – Division, M – Multiplication A – Addition, and S – Subtraction. The BODMAS rule states that mathematical expressions with multiple operators need to be solved from left to right in the order of BODMAS.
Now, 0.9(3÷2.25− 1 8 (1 2 3 + 1 9 ))− 4 7 ÷0.8.
=0.9(3÷2.25− 1 8×142)− 4 7 ÷0.8.
=0.9(1.33− 1 8×142)− 4 7 ÷0.8.
=0.9×(-2554.67)-58.75=-2357.953
Hence, the value of the given expression is -2357.953.

A college student realized that he was spending too much money on fast food. For the remaining 5 months of the year his goal is to spend a mean of $50 a month towards fast food. How much can he spend in December, taking into consideration that in the other 4 months he spent $100, $25, $80, and $30, respectively? Round your answer to two decimal places, if necessary.
Answer:
The college student can spend $15.00 in December.
Step-by-step explanation:
This can be calculated as follows:
Let y represents the amount to spend in December.
The can now us the formula for calculating a mean is as follows:
Mean = Sum of montlhy spending / Number of months ...... (1)
From the question, we have:
Mean = $50
Sum of monthly spending = $100 + $25 + $80 + $30 + y = $235 + y
Number of months = 5
Substituting the values into equation (1) and solve for y, we have:
$50 = ($235 + y) / 5
$50 * 5 = $235 + y
$250 = $235 + y
$250 - $235 = y
$15.00 = y
Therefore, the college student can spend $15.00 in December.

Find the ordered pairs for the x- and y- intercpets of the equations 3x-2y=18 and select the appropriate option below
Answer:
ordered pairs for the
x-intercept : (6,0)
y- intercepts :(0,9)
Step-by-step explanation:
Given equation : 3x-2y=18
X- intercept on coordinate plane is point where the line intersect the x- axis.
The coordinate of point y is 0 for x-intercept.
Based on this let the coordinate of X- intercept be (x,0)
we will plug this value in equation 3x-2y=18, to find value of x and hence we will get x-intercept
3x-2y=18
3x -2*0 =18
=> 3x = 18
=> x = 18/3 = 6
Thus, coordinate of x-intercept is (6,0)
________________________________________________
Y- intercept on coordinate plane is point where the line intersect the y- axis.
The coordinate of point x is 0 for y-intercept.
Based on this let the coordinate of X- intercept be (0,y)
we will plug this value in equation 3x-2y=18, to find value of y and hence we will get y-intercept
3x-2y=18
3*0 -2y =18
=> 2y = 18
=> y = 18/2 = 9
Thus, coordinate of y-intercept is (0,9)

Choose one of the theorems about chords of a circle and state it using your own words. Create a problem about chords that uses the theorem that you explained. Choose a problem that a classmate has posted, and explain how to solve it. Note: If you do not see any other responses, explain how to solve the problem that you posted. Please number your responses to the questions as they are shown (1, 2, and 3).
Answer:
Step-by-step explanation:
1. A given chord on a circle is perpendicular to a radius through its center, and it is at a distance less that the radius of the circle.
2. A circle of center O has a radius of 13 units. If a chord AB of 10 units is drawn at a distance, d, to the center of the circle, determine the value of d.
3. From question 2, the radius = 13 units, length of chord = 10 units and distance of chord to center of the circle is d.
A radius that meet the chord at center C, and divides it into two equal parts.
So that;
AC = CB = 5 units
Applying Pythagoras theorem to ΔOCB,
OC = d, CB = 5 units and OB = 13 units
[tex]13^{2}[/tex] = [tex]5^{2}[/tex] + [tex]d^{2}[/tex]
169 = 25 + [tex]d^{2}[/tex]
169 - 25 = [tex]d^{2}[/tex]
144 = [tex]d^{2}[/tex]
⇒ d = [tex]\sqrt{144}[/tex]
= 12 units
Therefore, the chord is at a distance of 12 units to the center of the circle.
A chord is a straight line joining 2 points on the circumference of a circle.
The line that connects any two points of the circumference of a circle is known as a chord.
Theorem: A radius or diameter that is perpendicular to a chord divides the chord into two equal parts and vice versa.
Converse: The perpendicular bisector of a chord passes through the center of a circle.
Problem: In the given figure the radius of the circle is 5 cms. what is the length of the chord?
Solution:
Given to us,
radius of the circle, r = 5 cms,
RA = 1 cm,
Radius, r = OA = OP = OQ = 5 cms.
Also, OR = OA - OR = 4 cms.
In ΔOPQ,
According to Pythagorus theorum,
OP² = OR² + RP²
5² = 4² + RP²
RP² = 25 -16 = 9
RP = 3,
We know,
A radius or diameter that is perpendicular to a chord divides the chord into two equal parts and vice versa.
A radius (OA) that is perpendicular to a chord divides the chord into two equal parts(RP = RQ).
Therefore, chord = RP + RQ = 3+3 = 6 cms.
