## A certain skin lotion is a fine mixture of water and various oils. This lotion is cloudy and cannot be separated into oil and water by filtration. Moreover, its components do not separate when left standing. What type of mixture is it? solution suspension colloid compound NextReset

The answer is: colloid.

In the presence of an emulsifying agent, a mixture of oil and water becomes a colloidal dispersion.

Colloidal dispersion (colloid) is a system, in which discrete particles, droplets or bubbles of a dispersed phase (in this case oil), whose size at least in one dimension is in the range from 1 to 1000 nm are distributed in the other, usually continuous phase – dispersion medium (in this case water) differing from the dispersed phase in composition or state of aggregation.

## The weights of certain machine components are normally distributed with a mean of 8.5 g and a standard deviation of 0.09 g. Find the two weights that separate the top 3% and the bottom 3%. These weights could serve as limits used to identify which components should be rejected. Round to the nearest hundredth of a gram.

To solve this problem,lets say that

X = the weight of the machine components.
X is normally distributed with mean=8.5 and sd=0.09

We need to find x1 and x2 such that
P(X<x1)=0.03 and P(X>x2)=0.03

Standardizing:

P( Z< (x1 – 8.5)/0.09 ) =0.03
P(Z > (x2 – 8.5)/0.09 ) =0.03.

From the Z standard table, we can see that approximately P
= 0.03 is achieved when Z equals to:

z = -1.88          and      z= 1.88

Therefore,

P(Z<-1.88)=0.03 and P(Z>1.88)=0.03

So,

(x1 – 8.5)/0.09 = -1.88 and
(x2 – 8.5)/0.09 =1.88

Solving for x1 and x2:

x1=-1.88(0.09) + 8.5   and
x2=1.88(0.09) + 8.5

Which yields:

x1 = 8.33 g

x2 = 8.67 g

Answer: The bottom 3 is separated by the weight
8.33 g and the top 3 by the weight 8.67 g.

## Which act by the British government caused the american colonists to write the declaration of independence and separate from great Britain? A) the destruction of a ship containing a load of British tea. B) the killing of several colonists by a group of British soldiers. C) the outlawing of slavery in all the american colonies. D) the requirement that the colonists pay taxes on British goods.

The right answer is “D) the requirement that the colonists pay taxes on British goods.”

The historic event known as the Boston Tea Party occurred on December 16, 1773 in the city of the same name, in the United States. The action was a protest carried out by the settlers of the country against the high taxes levied by the British government. The incident is considered a key event in the unfolding of the American Revolution.

The men who participated in the protest were imitated in many other cities of the country and ended up being known as the first heroes of the movement for the independence of the United States. After the revolt, the English government severely punished the inhabitants of Boston, closing the port of the city. Three years later, 13 colonies declared independence and founded the United States of America.

## Read the following excerpt taken from the US Supreme Court case Plessy v. Ferguson (1896). The case coming on for a hearing before the Supreme Court, that court was of opinion that the law under which the prosecution had was constitutional, and denied the relief prayed for by the petitioner. Ex parte Plessy, 45 La.Ann. 80. Whereupon petitioner prayed for a writ of error from this court, which was allowed by the Chief Justice of the Supreme Court of Louisiana. MR. JUSTICE BROWN, after stating the case, delivered the opinion of the court. This case turns upon the constitutionality of an act of the General Assembly of the State of Louisiana, passed in 1890, providing for separate railway carriages for the white and colored races. Acts 1890, No. 111, p. 152. The first section of the statute enacts “that all railway companies carrying passengers in their coaches in this State shall provide equal but separate accommodations for the white and colored races by providing two or more passenger coaches for each passenger train, or by dividing the passenger coaches by a partition so as to secure separate accommodations: Provided, That this section shall not be construed to apply to street railroads. No person or persons, shall be admitted to occupy seats in coaches other than the ones assigned to them on account of the race they belong to.” The Supreme Court’s ruling in Plessy v. Ferguson was problematic because

In the Plessy v. Ferguson case, the Supreme Court’s ruling of the “separate but equal” law being constitutional was problematic because the “separate but equal” law accepted segregation and the discrimination that were against blacks.

Industrialization led to rising imperialism because
1) show of power: As one makes new technology, they would either want to test it out or show the other nations that what they produce is ground-breaking and the best. Usually if it is military technology, you would want to test it out, and with the use of “show of force”, can have people groups submit to your country.
2) Better technology: As technology advances, it usually makes something easier. In the case of imperialism, better military advances meant that they could (once again) have other people submit to you
3) Better transportation: This meant that you could take multiple countries at once, and can prove that you’re country is great by having supplies shipped over long distances to keep your troops up. If in need of more troops, you could send more.

## Read the excerpt from the US Supreme court case Plessy v. Ferguson (1896). The statute of Louisiana, acts of 1890, c. 111, requiring railway companies carrying passengers in their coaches in that State, to provide equal, but separate, accommodations for the white and colored races, by providing two or more passenger coaches for each passenger train, or by dividing the passenger coaches by a partition so as to secure separate accommodations; and providing that no person shall be permitted to occupy seats in coaches other than the ones assigned to them, on account of the race they belong to; and requiring the officer of the passenger train to assign each passenger to the coach or compartment assigned for the race to which he or she belong; and imposing fines or imprisonment upon passengers insisting on going into a coach or compartment other than the one set aide for the race to which he or she belongs; and conferring upon officers of the train power to refuse to carry on the train passengers refusing to occupy the coach or compartment assigned to them, and exempting the railway company from liability for such refusal, are not in conflict with the provisions either of the Thirteenth Amendment or of the Fourteenth Amendment to the Constitution of the United States. Which best explains why the Supreme Court’s decision in Plessy v. Ferguson was unconstitutional? The Supreme Court’s ruling allowed states to deny equal protection to any person within its jurisdiction. Since the 14th Amendment did not make concessions for people born outside the US, the Supreme Court’s decision could not be applied. The Supreme Court’s decision gave individual states the freedom to make their own laws in relation to non-whites. Since segregation laws did not provide equal protections or liberties to non-whites, the ruling was not consistent with the 14th Amendment.

Hey there!

Correct answer is D. Comma or Period Inside Rule

A. Question mark or exclamation point inside: those are not really necessary.

B. Colon or semicolon: not, a semicolon would divide the whole sentence and it would be shorten; a colon would work but after requested, when there is already a comma.

C. Question mark or Exclamation Point Outside Rule: would not work, becase it is an very polite and affirmative sentence.

D: A comma or period inside rule: actually, just a comma would work. Please, Cooper’s dad requested, go… Cooper’s dad requested must be in between commas as it is a vocative.

Henri Rousseau’s Portrait of a Woman

Explanation:

Magical Realism finds precedent in eighteenth-century Gothic novels, but also connects with sixteenth-century Baroque or Surrealism, almost contemporary in the early twentieth century.

Among the most striking features of this movement, we find the blend of realism with pure unreality that is observed as normal, with the integration of magical elements without seeming extraordinary.

These works do not explain the supernatural elements and are narrated as something natural, with characters unaware of their transcendent dimension. In addition, death has paramount value in the relativistic discourse of truth, with a metaphysical focus on space and time and an intimate atmosphere that blends characters with myths, legends, and natural cultures.

Henri Rousseau’s Portrait of a Woman is considered one of the first magical realistic stories.

## What were the effects of the Plessy v. Ferguson decision? Check all that apply. It found the Fourteenth Amendment to be unconstitutional. It established a new precedent in declaring the law constitutional. It limited the rights of African American citizens. It allowed the policy of “separate but equal” to continue. It stopped states from creating segregation laws. it was b,c,d says edgeunity

The correct answers are

It established a new precedent in declaring the law constitutional- This ruling states that the laws that allow segregated for citizens in America was legal, as long as the facilities provided were “equal.”

It limited the rights of African American citizens– This case ruled in favor of seperate but equal facilities, resulting in African Americans receiving second class treatment in American society.

It allowed the policy of seperate but equal to continue– This law would continue from the 1890’s all the way through the middle of the 1950’s.

## Which evidence supports the endosymbiotic theory? Select all that apply. Mitochondria and chloroplasts have a separate, simpler DNA from the nucleus DNA of a eukaryotic cell. These organelles’ DNA resembles the DNA of prokaryotic cells. Mitochondria and chloroplasts self-replicate by a cell division process similar to binary fission, which is the way prokaryotes divide. The way mitochondria and chloroplasts synthesize proteins within the eukaryote cell is more similar to prokaryotes than to eukaryotes. There are living examples of prokaryotes, like cyanobacteria, that share similar features with both mitochondria and chloroplasts of eukaryotic cells. Observations of prokaryotic cells engulfing other prokaryotic cells and the engulfed cells becoming the organelles have been recorded.

In tropical rain forest, the animals will have to deal with higher temperatures and greater rainfall. One example of an adaptation they might need is a thin, water-proof coat. This will prevent heat from becoming trapped inside their fur/hair/feathers, and the water-absorbing coating will allow water to stick to the inside of the coat without being absorbed, where the water will absorb the heat instead of themselves, and will cool the through evaporative cooling (heat release through evaporation)

In a deciduous forest, there is much colder temperatures, and significantly less rainfall. These animals would likely want a thicker water-proof coat. This is because the thicker coat would allow heat to become trapped, keeping them warm in the winter, and the water-proof coating prevents water from freezing in their fur, making them colder.

## The senior classes at High School A and High School B planned separate trips to New York City. The senior class at High School A rented and filled 6 vans and 8 buses with 202 students. High School B rented and filled 12 vans and 10 buses with 284 students. Each van and each bus carried the same number of students. How many students can a van carry?How many students can a bus carry? please show work thank you.

Answer:  The correct option is (C). 10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared

Step-by-step explanation:  Given that the segment AB has point A located at (8, 9). The distance from A to B is 10 units.

We are to select the correct option that could be used to calculate the coordinates for point B.

Let, (x, y) be the co-ordinates of point B.

According to distance formula, the distance between two points (a, b) and (c, d) is given by

Therefore, the distance between the points A(8, 9) and B(x, y) is given by

Since, distance between A and B is 10 units, so

d = 10.

Therefore,

Thus, the correct statement is

10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared.

Option (C) is correct.

## Find all complex solutions of 3x^2+6x+1=0 . (If there is more than one solution, separate them with commas.)

So hmmm we’ll start off by using the decimal format for the percentage, thus 15% is just 15/100 or 0.15 and 7% is just 7/100 or 0.07 and so on

notice, the concentration of alcohol in the 15% is, well, 0.15 :), so for a quantity of whatever, it’d be 0.15whatever

anyway, for water… water has no alcohol whatsoever, so the concentration is 0%, or 0/100 which is 0.00 or a flat 0

we know that we’ll be adding “x” water with the 14mL to get “y”, thus 14+x = y

and the concentrated quantities will also add up to -> 14(0.15) = 2.1, thus
2.1 + 0x = 0.07y

solve for “x”.

## When creating websites, a designer must take into account that all browsers do not present HTML code in the same manner. There are at least three solutions to this problem: create separate versions of the site for each browser; gear the site to one browser and recommend the users view it in that browser: or use a newer design method of XHTML and CDS. Based on the reading so far, it appears using XHTML and CSS is the best solution. What type of problem-and -solution organization does this paragraph use?

Here are a few pointers; hope this is useful)

Ovation-by definition- is show of appreciation from an audience, for a person’s accomplishments or flaw.

“Everyone deserves a standing ovation because we all overcometh the world.”

A person’s accomplishment could be how they made a positive change in this world, strong leadership- that makes them a effective leader or simply helping others. A person’s flaw- mistakes in life, sin or even guilt should also be considered an appreciation- an ovation for representing mankind’s flaw and that humanity makes mistakes, fulfilling at least one deadly sin such as greed, lust, selfishness etc.

Thus, regardless of a person’s achievement or flaw- a person deserves an applause for, not the least, living in this society and this world that we are all living together and dying together.

That was just the introduction.. the best part is yet to come.. now it’s your turn!!

Here are other pointers to talk about in your essay:

Shakespeare’s famous line “All the World’s a stage. That agrees with your line: “Everybody deserves a standing ovation…”

Shakespeare explains that men and women are like players: they live, and die, some being celebrated and some forever living in solitude till their death. Shakespeare states the world is a “stage” which symbolizes that mankind is in its peak. The world is changing everyday: little by little and humanity is falling behind.
Due to our world turning into machinery: factories, an automotive future: where humans only job to live (entrance) and to die (exit) the famous humans remembered and the flawed not recalled.

This is according to Shakespeare’s imagery.

I don’t know what grade your in, but I think simplifying Shakespeare’s word of mouth in your essay would be handy and useful as it has strong references of your quote, and agrees strongly in your essay.

Hope this helps 🙂

## What methods can be used to rewrite square trinomials and difference of squares binomials as separate factors?

The basis to respond this question are:

1) Perpedicular lines form a 90° angle between them.

2) The product of the slopes of two any perpendicular lines is – 1.

So, from that basic knowledge you can analyze each option:

a.Lines s and t have slopes that are opposite reciprocals.

TRUE. Tha comes the number 2 basic condition for the perpendicular lines.

slope_1 * slope_2 = – 1 => slope_1 = – 1 / slope_2, which is what opposite reciprocals means.

b.Lines s and t have the same slope.

FALSE. We have already stated the the slopes are opposite reciprocals.

c.The product of the slopes of s and t is equal to -1

TRUE: that is one of the basic statements that you need to know and handle.

d.The lines have the same steepness.

FALSE: the slope is a measure of steepness, so they have different steepness.

e.The lines have different y intercepts.

FALSE: the y intercepts may be equal or different. For example y = x + 2 and y = -x + 2 are perpendicular and both have the same y intercept, 2.

f.The lines never intersect.

FALSE: perpendicular lines always intersept (in a 90° angle).

g.The intersection of s and t forms right angle.

TRUE: right angle = 90°.

h.If the slope of s is 6, the slope of t is -6

FALSE. – 6 is not the opposite reciprocal of 6. The opposite reciprocal of 6 is – 1/6.

So, the right choices are a, c and g.

## Read the excerpt from Brown v. Board of Education. In each of the cases other than the Delaware case, a three-judge federal district court denied relief to the plaintiffs on the so-called “separate but equal” doctrine announced by this Court in Plessy v. Ferguson, 163 U.S. 537. The Supreme Court cites these cases because it seeks to A.describe the unique situation in Delaware courts. B. illustrate the racial biases of federal court judges. C. establish the existing legal standard for education. D. share the unique differences between the given cases.

The sentence above is a compound-complex sentence.

Explanation:

A compound-complex sentence is made from two independent clauses and at least one dependent clause. The sentence above contains two independent clauses and two dependent clauses. The difference between an independent clause and a dependent one is that the former can stand on its own as a complete sentence because it represents a complete thought, while the latter can’t (see 1 & 2).

1) To cope with their burgeoning populations

2) Most of whom were unskilled workers looking for jobs in factories

1 and 2 are dependent clauses. As such, they can’t stand alone as complete sentences, they depend on the main clause.
