Step-by-step explanation:
This is a ratio problem.
It takes 6 quarts of red paint for mixing with 5 quarts of yellow paint to produce orange paint. The ratio of red/yellow is 6/5
If we double the quantity of yellow paint from 5 to 10 in the second case, the quantity of red paint will also double from 6 to 12 (first box)
In the 3rd case, the quantity of yellow paint is 10 times so quantity of red paint is 6 * 10 =60
In the last case, yellow paint is 20 times the original value of 5 so red paint is also 20 times original value = 6 * 20 = 120
The ratio of red paint to yellow paint is 6/5
So just multiply each value under yellow paint by this ratio to get the quantity of red paint
For example, for yellow paint = 10 quarts, red paint = 10 * 6/5 = 12 and so on

Each of them has deadly claws that rend and draw blood; each has a generous amount of fear and intimidation working for them; each has a healing factor that prevents them from being mortally wounded (eventually reaching preposterous levels of effectiveness); and each has killed and will kill if the situation calls for it. Yet there are differences, as well: Logan's skeleton, as well as his claws, are made of the unbreakable metal known as adamantium; and while there have often been instances where he's been shown to be merciless, he's not nearly as sadistic as Creed, who will not hesitate to kill even when there is no reason for it.

Cable Car is the preferred transportation for 75 residents. Bicycle is the preferred transportation for 30 residents. Together, Streetcar and Bus are the preferred transportation for 25 residents. Together, Bus and Bicycle are the preferred transportation for 54 residents.
Answers
The following conclusions can be drawn from the circle graph:
Cable Car is the preferred transportation for 75 residents. (27% of 300 = 81 residents)
Together, Streetcar and Bus are the preferred transportation for 25% of residents. (15% + 10% = 25% of 300 = 75 residents)
The other two statements are incorrect:
Bicycle is the preferred transportation for 8% of residents, not 30. (8% of 300 = 24 residents)
Together, Bus and Bicycle are the preferred transportation for 18% of residents, not 54. (10% + 8% = 18% of 300 = 54 residents)

all you need to do is plug the x and y values given in the table into the x and y of the equations
for example, if we used equation A. y=x+7 we would plug in our first set of x and y values: -6=1+7 but once you solve it you find it’s not true: -6≠8 so you know it isnt equation A
if we use equation D. y=2x-8 , plug in our values: -6=2(1)-8 it is true since 2-8=-6, giving us -6=-6

Answers
Answer:
f(x)=1/16(x-2)^2+2
Step-by-step explanation:
The Equation can be written like this:
f(x) = 1/(4p)(x -h)^2 +(k-p)
where (h, k) is the focus, and p is half the distance between focus and directrix. Here, (h, k) = (2, 6) and p=(6-(-2))/2 = 4. So the equation is ...
f(x) = 1/16(x -2)^2 +2

What is The Diary of Anne Frank?: It's the first, and sometimes only, exposure many people have to the history of the Holocaust.
1. How is this scene the happiest they have been since going into hiding?
In my opinion, this scene is the happiest they have been since going into hiding because the holocaust was very brutal because many individuals got executed and frightened throughout the Holocaust, and opening the gifts was a good way to temporarily forget about their problems.
2. Why does Margot not want to blow out the candles? Why does Mr. Frank say they need to?
Margot does not want to blow out the candles because they are supposed to be left to burn themselves out. Mr. Frank tells her God will understand that they need to conserve their Candles.
3. Explain Peter's prank on Mr. Dussel.
Peter was coming from his room as he was holding something in his coat which turned out to be a towel, but Mr. Dussel thought it was a cat. In the end, he was allergic to his clothes.
4. How does everyone react to Mr. Dussel's cat allergy?
Some seem to laugh at Mr. Dussel's cat allergy, but Mr. Van Dans wants to throw out Peter's cat for always eating their food. Peter said if Mr. Van Daans throws out the cat he will go out with it, but it didn't happen.
5. What happens that makes the mood change?
Something crashes below and they all freeze in horror. Peter tries to reach the lamp, but he can't so he gets up on a chair to try again but he ends up losing his balance and falling and then more steps can be heard below.
6. How was this scene the most scared
they have been since going into hiding?
Because they thought it was the Green Police or the Gestapo that have discovered their hiding place and had come to get them.
7. Describe juxtaposition and explain how this scene is an example of juxtaposition.
A writer can make readers sense of "goodness" in a particular character by placing him or her side-by-side with a character that is
predominantly "evil." In my opinion, this scene is an example of juxtaposition when Peter and Mr.
Van Dans had an argument about the cat, making Peter seem like a positive character while making Mr. Van Dans look like a negative character.
8. Describe how each person reacts in the situation when they are scared.
Mrs. Van Dans was panicking and saying to give the Green Police money
Anne was more concerned for her father because he went to check what happened below while her mother was trying to calmly put her in a state of relief. At some point, Anne asked who is going to look for Mr. Frank and Peter offered to show that he wasn't scared of any danger but Mr.
Dussel pushed Peter away in an angry tone. Mr.
Van Dans was as well calm and seemed to be more focused on what could happen next.
(I hope I did get every one right )
9. List the gifts that Anne gave to each person for Hanukkah. Then show how these gifts represent Anne maturing by saying what the thought or meaning behind each gift is.
1. Margot Frank: A crossword puzzle book / She never loses her temper.
2. Mrs. Van Dans: Hair shampoo / Mrs. Van Dans likes her hair (it doesn't seem to say in this scene, so I don't exactly know)
3. Mr. Van Dans: 2 cigarettes / Mr. Van Dans enjoys smoking (same as above)
4. Mrs. Frank: Ten hours of Anne doing what she says / Anne didn't get the time to repay her (that's what it made me believe)
5. Mr. Frank: A scarf / He found it in the first
scene
6. Mushi: A ball of paper with a string attached to it / For the cat to play with and stay entertained.
7. Peter: a safety razor / Peter was growing a mustache.
8. Mr. Dussel: earplugs / So he won't hear Anne making noise at night
Anne is maturing way faster because of the problems of what happens outside of their hiding as well. Every meaning of the gifts shows that Anne can see every little detail about people which not many kids can do.
l am sorry if l'm late, I had to do some research and listen to the audiobook of the specific scene.

jackie made bracelets for 8 days. when he was done he had 96 bracelets. write and equation to express how many bracelets jackie made each day.
Answers
Answers 12 bracelets per day
Answer:
12 bracelets.
Explanation:
If we assume Jackie made the same number of beaded bracelets each day, we can divide the total number of bracelets 96, by the amount of days it took to make all the bracelets, 8. This gives us
\(\frac{96}{8}\)=12
We can check the answer by working backwards. Each day 12 bracelets were made. There were 8 days. 12 × 8 = 96 . So for 8 days 12 bracelets were made giving Jackie 96 bracelets.

9. What is the area of a square with a perimeter of 44 mm?
10. What is the area of a square with a perimeter of 55 cm
Answers
Answer:
Step-by-step explanation:
To find the area of a parallelogram, multiply the base by the height:
Area = base x height
Area = 6.3 m x 27.3 m
Area = 171.99 m²
To find the height of a rectangle, divide the area by the base:
Height = Area / Base
Height = 420.92 mm² / 27.4 mm
Height ≈ 15.35 mm
The perimeter of a rectangle is given by 2 times the sum of the base and height:
Perimeter = 2(base + height)
133.2 mm = 2(30.6 mm + height)
133.2 mm = 61.2 mm + 2 height
2 height = 133.2 mm - 61.2 mm
2 height = 72 mm
Height = 72 mm / 2
Height = 36 mm
To find the height of a parallelogram, divide the area by the base:
Height = Area / Base
Height = 645 m² / 61 m
Height ≈ 10.57 m
The perimeter of a parallelogram is the sum of all its sides:
Perimeter = 2(base + side length)
Perimeter = 2(32 cm + 34 cm) + 2(height)
Perimeter = 2(66 cm) + 2(19 cm)
Perimeter = 132 cm + 38 cm
Perimeter = 170 cm
To find the area of a parallelogram, multiply the base by the height:
Area = base x height
Area = 40 mm x 18 mm
Area = 720 mm²
The perimeter of a rectangle is given by the formula: Perimeter = 2(base + height)
Perimeter = 2(7.9 m + 8.8 m)
Perimeter = 2(16.7 m)
Perimeter = 33.4 m
To find the height of a rectangle, divide the area by the base:
Height = Area / Base
Height = 354 cm² / 23 cm
Height ≈ 15.39 cm
The perimeter of a square is 4 times the length of one side. Since the perimeter is given as 44 mm, we can divide it by 4 to find the length of one side:
Side length = Perimeter / 4
Side length = 44 mm / 4
Side length = 11 mm
To find the area of a square, multiply the side length by itself:
Area = side length x side length
Area = 11 mm x 11 mm
Area = 121 mm²
The perimeter of a square is 4 times the length of one side. Since the perimeter is given as 55 cm, we can divide it by 4 to find the length of one side:
Side length = Perimeter / 4
Side length = 55 cm / 4
Side length = 13.75 cm
To find the area of a square, multiply the side length by itself:
Area = side length x side length
Area = 13.75 cm x 13.75 cm
Area ≈ 189.06 cm²

Please help! For the function f(x) = 2x^6 + 3x^4 - 4x^3 + (1/x) - sin(2x) find the first four derivatives.
Answers
Answer:
See the explanation
Step-by-step explanation:
We know that
f(x) = 2x⁶ + 3x⁴ - 4x³ + (1/x) - sin2x
Lets calculate the derivatives:
f'(x) = 6(2x⁵) + 4(3x³) - 3(4x²) -( 1/x²) - 2(cos2x)
f'(x) = 12x⁵ + 12x³ - 12x² - (1/x²) - 2cos2x
Similarly:
f''(x) = 60x⁴ + 36x² - 24x + (2/x³) + 4sin2x
f'''(x) = 240x³ + 72x - 24 - (6/x⁴) + 8cos2x
Rearrange:
f'''(x) - 240x³ +72x - (6/x⁴) + 8cos2x - 24
f''''(x) = 720x² + 72 + (24/x⁵) - 16sin2x
Rearrange:
f''''(x) = 720x² + (24/x⁵) - 16sin2x +72
