A student is buying thank you cards. Each than you card cost $2. The equation t = 2c represents the total cost, t, this student will spend to buy c cards. Which variable is the independent variable in the equation? Which is the dependent variable? Explain how you know.
Answers
Answer:
t is dependent and c is independent because if c increases so will t
The dependent variable, on the other hand, is the variable that is being measured or observed, and it is typically plotted on the y-axis of a graph. In this equation, "t" represents the total cost of the thank you cards, which is something that depends on the number of cards being purchased. The cost is not something that the student can control directly, but rather it is determined by the number of cards being purchased.
Therefore, in the equation t = 2c, "c" is the independent variable because it is being manipulated by the student, and "t" is the dependent variable because it depends on the value of "c".
The box plots below show the average daily temperatures in April and October for a U.S. city:
What can you tell about the means for these two months?
The mean for April is higher than October's mean.
There is no way of telling what the means are.
The low median for October pulls its mean below April's mean.
The high range for October pulls its mean above April's mean.
Answers
Answer:
A mean in math is the average of a data set, found by adding all numbers together and then dividing the sum of the numbers by the number of numbers. For example, with the data set: 8, 9, 5, 6, 7, the mean is 7, as 8 + 9 + 5 + 6 + 7 = 35, 35/5 = 7. So, assuming that's the type of "Mean" your talking about, there is no way of telling what the means are seeing as the picture only shows the averages.

Antonio is buying a stereo, speakers, and amplifiers for his car audio system. He is choosing among 4 models of stereos and 3 styles of speakers. If he has 36 different choices, how many kinds of amplifiers must there be?
2
3
4
12
Answers
Answer:
Let the number of kinds of amplifiers be "a".
Antonio has 4 choices for the stereo and 3 choices for the speakers. Therefore, the total number of different choices he can make is:
4 (choices of stereos) x 3 (choices of speakers) x a (choices of amplifiers) = 12a
We are given that he has 36 different choices, so:
12a = 36
Dividing both sides by 12, we get:
a = 3
Therefore, there must be 3 kinds of amplifiers.
The answer is (B) 3.

The mean is the sum of all values divided by how many values there are, if you add all values together and divide by 6 you'll get your answer, for example adding the numbers: 17, 19, 20, 14, 16, and 19 you get 17.5.
Jeff had $20. He spent 3/8 of his money on lunch. How much money does Jeff have left?
A. $12.50
B. $7.50
C. $8.25
D. $16.75
Answers
Answer: Option A, $12.50
Step-by-step explanation: Jeff spent 3/8 of his money, which can be represented by the equation as follows:
1 - 3/8 = 5/8
where 1 represents 8/8, or $20, and 5/8 represents the remainder of Jeff's money.
To find how much money Jeff has left, we can multiply his initial investment by 5/8:
$20 × 5/8 = $100/8, or $12.50
Hence, Jeff has $12.50 leftover, which is represented by option A.
Jeff has $7.50

Mateo’s old bedroom was a square with integer dimensions. His new bedroom is 3 feet wider and 2 feet longer. The increase in area is 46 ft^2. What were the dimensions of Mateo’s old bedroom?
Answers
Let x be the length of Mateo's old bedroom, then its width is also x since it is a square.
The new bedroom's length is x + 2 and its width is x + 3. The area of the new bedroom is (x + 2)(x + 3).
We know that the increase in area is 46 ft^2, so we can write an equation:
(x + 2)(x + 3) - x^2 = 46
Expanding the left side of the equation and simplifying, we get:
x^2 + 5x - 40 = 0
Factoring, we get:
(x + 8)(x - 5) = 0
Since the dimensions of the bedroom must be positive, we can discard the negative solution x = -8. Therefore, the length of Mateo's old bedroom is x = 5 feet, and its dimensions are 5 ft by 5 ft.

Frabjous Day
Everyone at our lunch table was silent; our small world had been rocked to the core. Derrick, president of the computer chess club stared at his lunch tray as if it held some sort of threatening, inedible concoction from another planet. Laurel, the leader of my literary discussion group, was pale, looking as though she were coming down with some nasty illness. We had just learned that Frabjous Day, the best and only bookstore in our small town might have to close. Business was just too slow. (The charming name, of course, was from Lewis Carroll's nonsense poem "Jabberwocky.") People were purchasing books online or downloading them to their e-readers. No one seemed interested in a real bookstore anymore. This impacted us not only because our groups met at Frabjous Day, but also because we believed that the bookstore added value to life and the community.
"We need to save Frabjous Day, and we have to get all our classmates involved in the effort," Laurel said, breaking the painful silence. She was right, but the obstacles in our way made climbing Mt. Everest look like a walk in the park. We represented just a few people at our school, and we had no idea how to reach everyone.
"My brother is always quoting his basketball coach," Derrick said, "One word that keeps coming up is 'strategy.' Maybe that's what we need: a unique strategy to get everyone to recognize the value of Frabjous Day and become involved in the store."
I admired the idea immediately. Come to think of it, my literary group had recently read a classical book on strategy called The Book of Five Rings. It was written in the 1600s by a Japanese swordsman, and it describes the necessity of discipline, perception, and outthinking your opponent. I remembered a quote about there being more than one path to the mountaintop, which seemed appropriate.
After several days, we had developed a plan. First we talked with our principal and then with the owner of Frabjous Day. Finally, we set up a big display at school under the banner STRATEGIES FOR SUCCESS. We exhibited books like the Five Rings and a book written by a championship-winning basketball coach. We had a book of political writings by Gandhi and another on effective environmental conservation. I personally selected biographies of successful people, including a biography on a fabulously successful actress. We had a big sign that read: "Build strategies for succeeding at what you love! Visit Frabjous Day this afternoon after school. You'll learn a lot and enjoy free sandwiches and cookies." Laurel thought of that last part because, after all, food always brings people together.
Crowds of students turned up that afternoon. We knew we needed them to actively commit to saving the store. Derrick, a master at chess strategy, devised a personalized group approach for the athletes. He showed students how to play a computerized strategy game, explaining how to use the idea on a personal or athletic level. Under a sign reading "Have a blind date with a book," Laurel set up a display of books covered in brown paper, with a brief handwritten description of the contents that was purposefully vague, yet very enticing. I invited a TV personality who grew up in our town. Everyone wanted to meet a real celebrity! Even better, people got excited about helping each other and the bookstore.
Our local librarian, Mr. Chung, contributed the best idea of all. His college roommate had been the now famous guitarist and singer Joel J. Mr. Chung and Joel were also best friends with Cecily Armstrong, whose latest mystery novel was on the best-seller list. Mr. Chung printed out raffle tickets to be given with each book sold. At the end of the year, some lucky winner would have his or her name in an original Joel J song lyric. Another lucky winner would be a character in Ms. Armstrong's next novel. The raffle was a huge success. There was no doubt that Frabjous Day was going to have many frabjous days ahead.

7.35 inches
7.65 inches
14.7 inches
17.35 inches
Answers
Answer: The required height of the tub is given as 7.35 inches.
Step-by-step explanation:The total surface area of the given cylindrical tub = 387.79 in.²
The diameter of the tub = 2r = 10 inches
where r = radius
r = 10/2 = 5 inches
T total surface of a cylinder = 2πr² + 2 π rh
387.79 = 2 * 3.14 * 5*5 + 2 * 3.14 * 5 * h
387.79 - 157 = 31.4h
h = 7.35 inches

Missing angle = 50°
Step-by-step explanation:
Given angles,
→ <A = 40°
→ <B = 90°
→ <C = ?
Now we have to,
→ Find the missing angle of triangle.
We know that,
→ Sum of angles of a triangle is 180°.
Formula we use,
→ <A + <B + <C = 180°
Let us assume that,
→ Missing angle = c
Forming the equation,
→ 40° + 90° + c = 180°
Then the value of c will be,
→ 40° + 90° + c = 180°
→ 130° + c = 180°
→ c = 180° - 130°
→ [ c = 50° ]
Hence, the value of c is 50°.

milk seller had 23.45 L. milk. He added 3.625 L water to it. How much was the quantity of the resultant mixture?
Answers
Answer:
Volume of milk = 23.45 L
Volume of water = 3.625 L
Total volume of the mixture = Volume of milk + Volume of water
Total volume of the mixture = 23.45 L + 3.625 L
Total volume of the mixture = 27.075 L
Therefore, the quantity of the resultant mixture is 27.075 L.
