The amount of time operators of a popular amusement park ride spend loading, safety checking, and unloading guests is 5 minutes per ride. The operators also spend 200 minutes each day completing other ride-related and guest-service tasks while the ride cars are in the station. The ride itself takes 3 minutes to complete. If the amusement park is open on Saturdays for 12 hours (720 minutes), write an inequality to describe how many cycles of the ride, at most, can be completed on a Saturday. Explain each term in your inequality.

Also how do you give a brainliest person

Answers

Answer:

200 + 3x + 5x ≤ 720

(or simplified, 200 + 8x ≤ 720)

and x = 65

Step-by-step explanation:

x represents the number of rides

3 + 5 = 8

720-200 = 520

520/8 = 65

The inequality for the number of rides will be 200 + 3x + 5x ≤ 720. The number of rides will be 65.

What is inequality?

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality showed greater than and less than the relationship between variables and the numbers.

Given that the number of time operators of a popular amusement park ride spends loading, safety checking, and unloading guests is 5 minutes per ride. The operators also spend 200 minutes each day completing other ride-related and guest-service tasks while the ride cars are in the station. The ride itself takes 3 minutes to complete. If the amusement park is open on Saturdays for 12 hours (720 minutes),

The inequality will be written as below,

200 + 3x + 5x ≤ 720

Here, x represents the number of rides

3 + 5 = 8

720-200 = 520

520/8 = 65

Therefore, the inequality for the number of rides will be 200 + 3x + 5x ≤ 720. The number of rides will be 65.

Savannah decides to download some new music. she downloaded 5 albums and 7 singles, and his total was $71. The next day she purchased more music from the same retailer and downloaded 3 more albums and 6 singles for a total of $48.

Assuming that all albums and singles are the same prices, how much did she spend on each album and each single? Write a system of equations to represent this situation. Then solve for the solution using the elimination method.

Answers

Answer:

Step-by-step explanation:

downloaded= 5 albums and 7 singles and total price is $71

Know,

           album + singles = 5+7=  12

           ∴ price÷ from total of albums and singles

              $71÷12=$5.92

 per album     = $5.92

 per single     =  $5.92

Next day;

                3+6=9

    total price =$48

                 ⇒ =$48÷9 = $5.3

     per album= $5.3

     per album= $5.3

"""""  I just try to Solve """"""

Answer:  Singles are $3/each and albums are $10 each.

Step-by-step explanation:

Let A and S represent the number of Albums and Singles, respectively.

We are told that:

5A + 7S = $71

and also that:

3A + 6S = $48

We have two equations and 2 unknowns.  Use elimination to find the price of one and then that will tell us the price of the other.  I'll choose to eliminate the A:

5A + 7S = $71

3A + 6S = $48

We can do the elimination in one of 2 ways:

1)  Solve one of the equations for A or S, and substitute it in the other:

3A + 6S = $48

3A  = $48 - 6S

A  = ($48 - 6S)/3

Now use this definition of A in the first equation:

5A + 7S = $71

5(($48 - 6S)/3) + 7S = $71

5(($48 - 6S)/3) + 7S = $71

$80 - 10S + 7S = $71

-3S = - 9

S = $3

Now we can find A:

5A + 7S = $71

5A + 7(3) = $71

5A + 21 = $71

A = $10

======

2)  We could also modify one of the equations and then subtract to eliminate a variable:

5A + 7S = $71

3A + 6S = $48

Let's multiply the second equation by -(5/3):

-(5/3)*(3A + 6S = $48)

-5A - 10S = -90

Now add this to the first equation:

5A + 7S = $71

-5A - 10S = -80

  - 3S = - 9

S = $3 and therefore A = $10

To join the speech and debate club, there is a $28.90 initial fee and a $2.20 yearly fee. Write an equation in slope-intercept form where x represents the number of years enrolled in the club, and y represents the total amount of fees paid.​

Answers

First off, initial is your y intercept. Your starting point, with that being said. Your slope is the “yearly fee”. You can solve from there

The equation that represents the total cost of the club will be y = 2.20x + 28.90.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

To join the discourse and discussion club, there is a $28.90 beginning charge and a $2.20 yearly expense.

Let 'x' be the number of years and 'y' be the total cost. Then the equation is given as,

y = 2.20x + 28.90

Where the number 2.20 represents the slope and the number 28.90 represents the y-intercept of the line.

The actor stands alone, saying his lines. However, when you see the actual movie, he is talking to a formidable seven-foot-tall monster in a creepy dark forest. A process called blue-screen technology is used to insert images into a background. Today, moviemakers use this process to combine digitally created, or computer-generated, characters with real people on the screen. Heres how it works:The scene calls for a real character to interact with a seven-foot-tall digitally created monster. First, the real characters part must be filmed. He may rehearse with another actor who plays the part of the monster. During the rehearsal, the monster might wear a tall hat to represent the stature of the monster. The real actor practices looking at the top of the hat during the scene so that is seems that he is looking up at a very tall creature. The actor gets used to where the monster stands and moves. The monsters movements are marked on the floor so that the actor doesnt walk on top of the monster during the scene. Then it is time for the scene to be shot. The actor stands alone in front of a blue screen and delivers his lines as if the monster were there. Eventually, the blue background is deleted, using a computer, and images of the digital monster and background are then transferred to the film.Which of these steps is second in the blue-screen process?a.The real character rehearses his part with another character playing the monster.c.The blue background is deleted, using a computer, and images of the digital monster and background are then transferred to the film.b.The scene is shot.d.none of the abovePlease select the best answer from the choices providedABCD PLS help i need this done now!
