Answers

Answer:

x = 7 - 3y

Step-by-step explanation:

6y + 2x = 14 (divide all by two)

3y + x = 7 (move 3y to the right to isolate x)

x = 7 - 3y

Answer:

7-3y=x

Step-by-step explanation:

6y+2x=14

2x=14-6y >>> isolate x variable

Justin owns a food truck that sells tacos and burritos. He only has enough supplies to make 110 tacos or burritos. He sells each taco for $3.25 and each burrito for $5.75. Justin must sell a minimum of $520 worth of tacos and burritos each day. If 39 tacos were sold, determine the maximum number of burritos that the Justin could sell that would meet the requirements. If there are no possible solutions, submit an empty answer.

Answers

Answer:

so looks its an easy one

110 - 39 = 71

71 x 5.75 = 408.25

39 x 3.25 = 126.75

408.25 +126.75 = 535

71 burritos and 39 tacos = 535 dollars

69 burritos

What is mathematical expression?

A mathematical expression is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Tacos sold = 39

Burritos sold = x

Let x be the number Burritos sold

each taco sold for $3.25

each burrito sold for $5.75.

Total sell = $520

Now according to the given question,

39*3.25 + x*5.75 = 520

126.75 + 5.75x = 520

5.75x = 393.25

x = 68.39

x ≈ 69

Therefore, Justin has to sell 69 burritos to meet the requirements.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

She gives 4 treats to Tucker.

Then splits the remaining treats between Bogey and Murphy, who get 3 treats each.

So, if bogey and murphy each get 3 treats and tucker gets 4 then

= 3+3+4

=10 treats

Hence, at beginning Jasmine starts with 10 treats.

What is the phenomenon that many types of data analysis become significantly harder as the dimensionality of the data increases? a. The Curse of Dimensionality b. The Phenomenon of Reduction c. The Curse of Reduction d. The Phenomenon of Dimensionality

Answers

Answer:

a. The Curse of Dimensionality

Step-by-step explanation:

The phenomenon that refers to this is known as the Curse of Dimensionality. This phenomenon is basically the specific complications that only occur when dealing with far larger data sets that contain various dimensions, while these complications do not exist in smaller and less complex data sets. The larger the data set tends to get, the more complications arise. This is usually solved with Dimensionality reduction which shrinks the data sets by targeting specifics of the data and separating it.

VX
O y=-5x+12
O 5x+y=12
O y-12=5(x-0)
O 5x+y=-1

Answers

Answer:

Step-by-step explanation:

y=-5x+12

10x+2y=-2

Subtract 10x to the other side of the equation and you will get 2y=-10x-2

Then divide both side by 2 to get y by itself

It will lead you to y=-5x+1

Notice that your point is (0,12) and it says parallel so you will keep your slope but your y-intercept will change

Final answer: y=-5x+12

I believe it's y= -5x+12. I really hope this helps. Happy schooling!!

Answers

Answer:

(A) Independent

(B) Independent

(C) Independent

Step-by-step explanation:

Independent samples are those samples are drawn from two different population.

Dependent samples are sample collected from the same population but at different times. They are also known as matched pair samples.

(A)

The data collected is for the pair of ages of actresses and actors at the times that they won Oscars for Best Actress and Best Actor categories.

That is the data is in the form (x, y). Here x represents the age of actresses and y represents the age of actors.

Since the data is collected from two different population of male and female, the sample are independent.

(B)

The data collected is for the heights of elected presidents along with the heights of their main opponents.

Again the data is in the form (x, y). Here x represents the heights of elected presidents and y represents the heights of the main opponents.

The samples collected is independent.

(C)

The data collected is for the volumes of the contents in 36 cans of regular Coke and the volumes of the contents in 36 cans of regular Pepsi.

Again the data is in the form (x, y). Here x represents the volumes in the regular Coke cans and y represents the volumes in the regular Pepsi cans.

The samples collected is independent.

Answers

9514 1404 393

Answer:

  8 units

Step-by-step explanation:

Displacement is the area under the velocity curve. The area of interest is in the shape of a trapezoid, so we can use the formula ...

  A = (1/2)(b1 +b2)h

to find the area.

Here, b1=3, b2=1, h=4, so the area is ...

  A = (1/2)(3 +1)(4) = 8

The displacement is 8 units in the time from t=1 to t=4.

Solve the equation: |2x + 5| = 11.

Answers

Answer:

x = -8 and x = 3

Step-by-step explanation:

Split the equation into 2 possible cases:

2x + 5 = 11

2x + 5 = -11

Then, solve these 2 equations.

2x + 5 = 11

2x = 6

x = 3

2x + 5 = -11

2x = -16

x = -8

So, the 2 solutions are x = -8 and x = 3

Robots on EarthRobots on Earthby Jerry WestExplosions. Car chases. A man and woman, drenched in sweat, limping from a building as it crumbles to the ground, muster the last of their strength to rescue humanity from its inevitable extinction at the cold, metal hands of humanoid creatures with artificial intelligence gone awry. For decades, books and movies have dictated how we think of robots. Simply the word "robot" can bring to mind images of evil, mechanical creatures bent on taking over the world and wiping out every glimmer of humanity. And yet, the truth of machines is dramatically different. Today's robots hold little in common with their villainous cousins from action-packed science fiction. Most robots have no interest in harming the human population at all; they exist to aid people in making life safer, healthier, and more productive.For example, jobs such as welding and painting are important to civilization as we know it, but experience has taught us that these activities can be hazardous to human health. In addition, fumes in automobile and airplane factories can harm organic bodies that become exposed to their toxins in the assembly process. Even when the best precautions are taken, workers may still suffer from lack of adequate ventilation. What is the answer to these difficult dilemmas? Robots. Because machines don't rely on clean air or comfortable temperatures, because they can function even in the midst of deadly gasses, they can take over with ease where humans would suffer greatly. Working together, humans and robots can get the job done.A robot's job isn't limited to the terrestrial level, either. Even in space, machines such as the R2 humanoid robot at the International Space Station complete dangerous tasks for astronauts, protecting them from potentially deadly situations. And then, when there are mundane but essential tasks to conduct on the space station, R2 takes care of those, as well, freeing up the astronauts' time for more important responsibilities. Thus, in space and on Earth, robots manage to create healthier, happier humans.In fact, there are robots on Earth that exist specifically to boost human health. Just as contact lenses enhance human sight, robotics can increase human mobility. People with disabilities and various forms of paralysis now have hope that they can achieve better range of motion, when before this wasn't possible. With the help of robots, scientists are working to create an exoskeleton that will attach itself to the outside of the human body, establishing a connection to the human brain. Neuroscientist Miguel Nicolelis has a dream. "We are working with the Brazilian government, who is helping fund the project. At the 2014 soccer World Cup celebrations we hope to have a Brazilian teenager with quadriplegia walk out and make the opening kick."Explosions and car crashes may sell tickets for the summer blockbuster, but robots have so much more to offer, and much of it is positive service to humans. At the heart of the field of robotics is not the creation of people-destroying machines with evil artificial intelligence, but something much more useful. Robots aren't our enemies; instead, they are the valuable result of scientific endeavors to create safer lives for people everywhere.Write a summary of the article:Write a main idea sentence for each paragraph of the article.Put your main idea sentences together to create the first draft of your summary paragraph and include a topic sentence.Revise your draft to make it more concise, effective, and objective.Proofread your paragraph for complete sentences, proper punctuation, and correct spelling.Remember that the summary should be objective and should not include your opinions or experiences.thanks and brainleast A speed skater moving across frictionless ice at 8.8 m/s hits a 6.0 m -wide patch of rough ice.
