How much alcohol must a pharmacist add to 10 cm^3 of an 8% alcohol solution to strengthen it to an 80% solution? PLS ANSWER URGENT THANKS
The pharmacist must add [tex]36 cm^3[/tex] of pure alcohol to the [tex]10 cm^3[/tex] of 8% alcohol solution to obtain an 80% alcohol solution.
What is alcohol ?Alcohol, also known as ethanol is a clear, colorless liquid that is produced by the fermentation of sugars and carbohydrates by yeasts.
Let's start by writing down the equation that relates the amount of alcohol in the original 8% solution to the amount of alcohol in the final 80% solution:
[tex]0.08 x 10 cm^3[/tex] [tex]+ x = 0.80 x (10 cm^3 + x)[/tex]
Here, x represents the amount of pure alcohol that we need to add to the [tex]10 cm^3[/tex] of 8% solution to obtain the desired 80% solution.
The left-hand side of the equation represents the amount of alcohol in the original solution (which is 8% alcohol), while the right-hand side represents the amount of alcohol in the final solution (which is 80% alcohol).
Now we can solve for x:
[tex]0.08 x 10 cm^3 + x = 0.80 x (10 cm^3 + x)[/tex]
[tex]0.8 cm^3 + x = 8 cm^3 + 0.8x[/tex]
[tex]0.2x = 7.2 cm^3[/tex]
[tex]x = 36 cm^3[/tex]
Therefore, the pharmacist must add [tex]36 cm^3[/tex] of pure alcohol to the [tex]10 cm^3[/tex] of 8% alcohol solution to obtain an 80% alcohol solution.

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
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.

Ice cream is packed in cylindrical gallon tubs. A tub of ice cream has a total surface of 387.79 square inches. If the diameter of the tub is 10 inches, what is it's height? use n = 3.14.
7.35 inches
7.65 inches
14.7 inches
17.35 inches
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

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.

The angles which are formed inside the two parallel lines, when intersected by a transversal, are equal to its alternate pairs.
q and t are alternate interior
r and k are alternate interior
W is 79
The mistake he made is equating an alternate interior angle to an alternate exterior angle
1 .When two parallel lines are crossed by a transversal, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. These angles are always equal.
Alternate exterior angles are those angles that have different vertices, lie on the alternate sides of the transversal, and are exterior to the lines. When a transversal intersects two parallel lines, the alternate exterior angles formed are always equal.
2. check the picture for translation of the angles
3. 8 angles are created, 4 alternate interior and 4 alternate exterior
Angles 6,4 and 2 are congruent to 8
In question 8, the equation above must be equal to the written degree below. Your image isnt so clear

milk seller had 23.45 L. milk. He added 3.625 L water to it. How much was the quantity of the resultant mixture?
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.
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.
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.

The singh family orderd a large pizza with a diameter of 20 inches for dinner. If one of the members ate one-eighth of the pizza, how many square inches of pizza are remaining? (use 3.14 for pi)
Answer:
275.5 square inches of pizza remaining
Step-by-step explanation:
The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle.
The diameter of the pizza is 20 inches, so the radius is half of that, or 10 inches.
The area of the entire pizza is:
A = πr^2 = 3.14 x 10^2 = 314 square inches.
If one member of the family ate one eighth of the pizza, then the amount of pizza remaining is 7/8 of the original amount.
The remaining area of the pizza is:
(7/8) x 314 = 275.5 square inches.
Therefore, there are 275.5 square inches of pizza remaining.

Gianna and her family went for a drive. They traveled 175 miles in 3 hours. What was their average speed?
Would you write an inequality or an equation?
To find the average speed, we divide the total distance traveled by the time taken:
Average speed = Total distance ÷ Time taken
Therefore, Gianna and her family's average speed is:
Average speed = 175 miles ÷ 3 hours = 58.33 miles per hour (rounded to two decimal places)
We use an equation to solve this problem.
Equation: Average speed = Total distance ÷ Time taken
Where:
Total distance = 175 miles
Time taken = 3 hours
Substituting these values into the equation, we get:
Average speed = 175 miles ÷ 3 hours
Therefore, the answer is an equation:
Average speed = 175 miles ÷ 3 hours
