HELP will give 50 pts. A group of friends wants to go to the amusement park. They have $197.75 to spend on parking and admission. Parking is $19, and tickets cost $35.75 per person, including tax. Write and solve an equation which can be used to determine xx, the number of people who can go to the amusement park.
i need to know the equation and the answer
To write the equation multiply the price per person by x( the number of people that can go) and add the price of parking to get the total cost:
equation: total = 35.75x + 19
to solve for x replace the total with 197.75 and solve for x:
197.75 = 35.75x + 19
Subtract 19 from both sides:
178.75 = 35.75x
Divide both sides by 35.75
X = 5
a total of 5 people can go.
Solve for x. 3/4x - 2=8
Answer:
Solve for [tex]x[/tex] by simplifying both sides of the equation, then isolating the variable.
Exact Form:
[tex]x = \frac{40}{3}[/tex]
Decimal Form:
[tex]x=13.3[/tex]
Mixed Number Form:
[tex]x=13\frac{1}{3}[/tex]

An angle between 0 and 2π that is coterminal with 960° is
Answer:
4 pi/3
Step-by-step explanation:
960 degrees in standard position is the same thing as 960-360 = 600 degrees in standard position because rotating the second line 360 degrees just brings it back to where it started.
Do it again to get 600 - 360 = 240
240 degrees would end up in the same spot as 600 degrees and 960 degrees, so they are all coterminal.
Convert 240 degrees to radians:
240 * pi/180 = 4pi/3.

At the airport, ten people are waiting on standby. two seats become available, one first class and one coach. how many ways are there to fill the two seats?
At the airport, ten people are waiting on standby. two seats become available, one first-class and one coach, There are 90 ways to fill the two seats.
It is given that there are ten people waiting on standby.
Two seats are available, One is first class and another one is coach.
It is required to find how many ways are there to fill the two seats.
What is permutation?A permutation can be defined as the number of ways a set can be arranged.
We have ten people and two seats in which only two people can seat out of ten.
It is a problem based on the permutation concept.
So for the first seat, there are 10 ways to fill the first seat
and for the second seat, there are [tex](10-1)[/tex] ways to fill the second seat.
If "P" is the number of ways we can assign the seats:
Then, P = 10×(10-1) = 10×9 = 90
Thus, there are 90 ways to fill the two seats.

suppose you deposit $2000 in a savings account that pays interest at an annual rate of 5% if no money is added or withdrawn from the account how many years will it take for the account to contain $2500 and how many years will it take for the account to contain $3000
Answer:
$2500: 4.57 years$3000: 8.31 yearsStep-by-step explanation:
The time required for an account earning compound interest to achieve a particular balance is given by the formula ...
t = log(A/P)/(n·log(1 +r/n))
where principal P is compounded n times per year at annual rate r. A is the account balance after that time. For this problem, n=1.
__
a.Here, we have ...
P = $2000, A = $2500, r = 0.05, n = 1
The number of years is ...
t = log(2500/2000)/log(1.05) ≈ 4.57 . . . years

has the coordinates given.
H (0, 0), I (-3, -1), J (-1, -2)
Find the new coordinates after the translation 3 unit to the right and 2 units down.
Answer:
H'(3, -2)I'(0, -3)J'(2, -4)Step-by-step explanation:
The x-coordinate of a point is the number units to the right of the y-axis where the point may be found. Translating the point to the right adds to the x-coordinate. Translating to the left subtracts from the x-coordinate.
The y-coordinate of a point is the number of units above the x-axis where the point may be found. Translating the point upward adds to the y-coordinate. Translating downward subtracts from the y-coordinate.
__
When a point is translated 3 units right and 2 units down, its x-coordinate has 3 added to it, and its y-coordinate has 2 subtracted from it. We can summarize the transformation like this:
(x, y) ⇒ (x +3, y -2)
Applying this transformation to the given points, we find ...
H(0, 0) ⇒ H'(3, -2)
I(-3, -1) ⇒ I'(0, -3)
J(-1, -2) ⇒ J'(2, -4)
What is the slope of the line that passes through the points (3,9) and (7,5)? Write
your answer in simplest form.
Answer:
M = -1
Step-by-step explanation:
Use the slope formula:
M = (y2-y1)/(x2-x1)
M = (5-9)/(7-3)
M = -1
The required slope for the lines -1.
Given that,
To determine the slope of the line that passes through points (3,9) and (7,5).
What is the slope of the line?The slope of the line is a tangent angle made by line with horizontal. i.e. m = tanx, where x is in degrees.
What is simplification?The process in computation to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Slopes of the line can be given as,
m = [y₂ - y₁ ] / [x₂ - x₁]
for points, (3,9) and (7,5)
m = 5 - 9 / 7 - 3
m = -4 / 4
m = 1
Thus, the required slope for the lines is -1.

A bedroom is 15 ft long and 12 ft wide. How much will it cost to carpet the room if carpeting costs $22 per square yard?
Answer:
$1,320
Step-by-step explanation:
To find the area of the bedroom, you must multiply the length and the width. 15 multiplied by 12 is 180, so the area of the bedroom is 180 square feet. There are three feet in a yard, so you must divide the area of the bedroom in feet by 3 in order to get the area of the bedroom in yards. 180 divided by 3 is 60, so the area of the bedroom is 60 square yards. In order to find how much it will cost to carpet the room, you must multiply the area of the bedroom in yards by how much carpeting costs per square yard. 60 multiplied by 22 is 1,320, so it will cost $1,320 in order to carpet the room.

The number of tickets sold each day for an upcoming performance is given by p(x) = -0.4x2 + 8.8x + 13, where x is the number of days since the concert was first announced. When will daily ticket sales peak and how many tickets will be sold that day?
Answer:
The maximum sale of the tickets is 158 on the [tex]11^{th}[/tex] day.
Step-by-step explanation:
The number of tickets sold each day, p(x), for an upcoming performance is
[tex]p(x)=-0.4x^2+8.8x+13[/tex]
where x is the number of days since the concert was first announced.
For peak sales, the point of maxima has to be determined.
So, differentiate the function of the number of tickets sold each day, p(x), with respect to the number of days, x, and equate it to zero to get the extremum point (maxima or minima), i.e.
[tex]\frac {p(x)}{dx}=0[/tex]
[tex]\Rightarrow -0.8x+8.8=0[/tex]
[tex]\Rightarrow x=\frac{8.8}{0.8}=11[/tex]
Now, check the sign of the second derivative at x=11, to ensure the obtained point is corresponding to the maxima or minima,
[tex]\frac {p^2(x)}{dx^2}=-0.8[/tex]
As the second derivative is negative, so x=11 is the point corresponding to maxima.
Hence, on the [tex]11^{th}[/tex] day the daily ticket sales will be at the peak.
Putting x=11 in the function p(x) to get the number of tickets sold that day.
[tex]p(x=11)= -0.4(11)^2+8.8(11)+13[/tex]
[tex]\Rightarrow 158.2.[/tex]
The number of tickets should be an integer, the obtained peak value is 158.2 so the higher integral value is not possible but the lower integral value is possible.
So, the maximum sale of the tickets is 158 on the [tex]11^{th}[/tex] day.
