Economic profit is calculated as:

Economic profit = Total Revenues – Total Cost

Total cost both includes explicit and implicit cost. In
this case, the explicit cost is $8,000 while the implicit cost is $64,000.
Explicit cost is a direct payment made to run the business while implicit cost
is the opportunity as accountant that is lost. Therefore,

Economic profit = $150,000 – ($8,000 + $64,000)

Economic profit = $78,000

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.

Read this quote from Zimmermann in The Code Book. In the past, if the government wanted to violate the privacy of ordinary citizens, it had to expend a certain amount of effort to intercept and steam open and read paper mail, or listen to and possibly transcribe spoken telephone conversations. This is analogous to catching fish with a hook and a line, one fish at a time. Fortunately for freedom and democracy, this kind of labor-intensive monitoring is not practical on a large scale. Today, electronic mail is gradually replacing conventional paper mail, and is soon to be the norm for everyone, not the novelty it is today. Unlike paper mail, e-mail messages are just too easy to intercept and scan for interesting keywords. This can be done easily, routinely, automatically, and undetectably on a grand scale. This is analogous to driftnet fishing—making a quantitative and qualitative Orwellian difference to the health of democracy. What is the purpose of the quote from Zimmermann? It explains how much faster e-mail travels than ordinary mail. It shows how easily digital mail can be monitored by outsiders. It states exactly how many people use e-mail instead of regular mail. It proves that e-mail is better for the health of democracy than regular mail.

Kamala Markandaya  was a pseudonym used by Kamala Purnaiya Taylor who was born on 01 January 1924 and died on 16 May 2004. She was an Indian novelist and journalist. A native of Mysore, India, Markandaya was a graduate of Madras University, and afterwards published several short stories in Indian newspapers. After India declared its independence, Markandaya moved to Britain, however, she still considered herself an Indian expatriate long afterwards.

Known for writing about culture between Indian urban and rural societies, Markandaya’s first published novel, Nectar in a Sieve, was a bestseller and cited as an American Library Association Notable Book in 1955.

The book is set in India during a period of intense urban development and is the chronicle of the marriage between Rukmani, youngest daughter of a village headman, and Nathan, a tenant farmer. The story is told in the first person by Rukmani, beginning from her arranged marriage to Nathan at the age of 12 to his death many years later.

Food is a critical aspect in the development of the story, Rukmani and Nathan struggle to feed their children and to pay the rent on the land that gives them life. Although difficulties continue to worsen, they quietly resign themselves to ever-increasing sufferings: flood, famine, even death, yet they stick to their hopes for a better future.

One definition of the word season as it is used in Nectar in a Sieve is that:

it is a period of the year associated with something in particular that happens every year

Hey there!

Let’s assume that this question is referring to every digital calendar ever made. As in, even those made on devices without internet connectivity or any other fancy features that we utilize with many digital calendars today. 

If a planning device that came with a digital calendar didn’t have internet connectivity, it wouldn’t be able to be connected to the cloud. Back when these devices were around, it wasn’t even plausible to store things like calendar events and contacts in what we know as the “cloud”. Also, these devices probably had to be hardwired to a computer and new software had to be downloaded to them, so the updates weren’t automatic. Archaic, right?

Also, consider the fact that even reputable websites/companies such as Google with Google Calendars or Apple with iCalendar will never go without their malfunctions or threats. Sometimes, these websites can be hacked and the data that they contain can be compromised, especially if they’re stored on the cloud. Also, even though it’s not realistic, Google or Apple could one day decide to completely get rid of their calendar programs altogether. So, this means that digital calendars are definitely able to be destroyed or lost. 

That just leaves “They can be used anywhere”. This is true, even with those archaic devices specifically used for scheduling events and such. Nowadays, you have your phone and possibly a laptop on you at all times, which will likely have a calendar on it as a stock application. So, I think this is your answer. 

Hope this helped you out! 🙂

However, they also point out that it’s OK to have an unusual kind of family structure. On One Tree Hill, for example, Lucas is being raised by a single mom, and he has a close relationship with his uncle, but his dad isn’t completely out of the picture. On a teen show such as iCarly, on Nick, Carly’s older brother plays the role of guardian, because her dad is in the Air Force. Her mom is never really spoken of. 

2. I do feel that most of the portrayal of family is accurate, on TV. Modern shows have steered away from the conventional “Mom, Dad, 2.5 kids plus dog” formula, which is accurate, because not all TV watchers are fortunate enough to have that kind of situation. See above answer for specific examples. 

3. I think that a definite negative theme in today’s modern shows, revolve around views on alcohol and drugs. Obviously everyone is entitled to their own views, but more often than not, after a character drinks, or does something they shouldn’t, they panic about what their parents will do once they find out. This panic may lead them to increasingly dangerous situations. For example, in OTH, Nathan is drinking, and then goes out to drive his girlfriend’s car. When he crashes it into another car, he realizes the trouble he is in, and leaves the scene of the accident; thus potentially getting him in even more trouble. I realize that TV is in no way an accurate depiction of all life aspects, and it is “only TV”, but I think Nathan should have faced the consequences right away, because by running from the scene, he only put himself in danger of being caught, or arrested. Again, though, I’m reading too much into it.

Answer:

$2.43 per gallon of gas.

Step-by-step explanation:

We have been given that the amount of money it takes to fill up a gas tank varies directly with the number of gallons bought.

We know that the equation for two directly proportional quantities is in form: y=kx, where,

k = The constant of variation and y is directly proportional to x.

To find the constant of variation for our given equation, we will substitute the given values in above equation as:

$21.87=k*9text{ gallons}

Let us divide both sides of our equation by 9 gallons.

frac{$21.87}{9text{ gallons}}=frac{k*9text{ gallons}}{9text{ gallons}}

frac{$2.43}{text{ gallon}}=k

Therefore, the constant of variation is $2.43 per gallon of gas.

Answer;

B. Mass and energy are equivalent.

Explanation;

-Each of the letters of E = mc2 stands for a particular physical quantity.

E is the energy, m is the mass and c is the speed of light (m/s)

 Energy = mass x the speed of light squared

-The equation E=mc2 explains nuclear fusion, how matter can be destroyed and converted to energy and energy can be converted back to mass. It explains the atomic energy produced by nuclear power plants and the atomic energy released by atomic bombs.

-The equation tells us that mass and energy are related, and, in those rare instances where mass is converted totally into energy, how much energy that will be.

I would say not. The passage does not seem to criticize

This one doesn’t seem right either. If anything it seems to
explain the opposite as Arnetta’s father enlist her for it.

 

“to describe the Supreme Court’s legal

Later, in Act 3 scene i, we find Mercutio and Tybalt fighting, eventually killing Mercutio. The Prince had given the decree in Act I scene i of no public duels which was emphasized again by Romeo in Act 3 scene i when he tried to break up their fight. But he knows that since he is a relative of the Prince, he might be saved from the decree. So, Mercutio wasn’t afraid to fight Tybalt when the latter abused Romeo.

1 D. You can donate at any age.

In united states, there is no laws/regulation that prohibit you form donating to charitable organizations. These action would be considered as an act of elevating social problems that are faced by other people in society. The only legal risks can only occurs if you somehow use the charity as a method to disguise your tax payment.

2 false

You can make a donation to non-profits anytime you want. But, to ensure that your donation does not go to waste, you need to conduct a little research on the non-profit organization. Make sure that they had proof of their work and not just around to steal your hard earned money.

3. C.Fortune 500 company.

The only difference between the two is where the sense of achievement come from. Working for fortune 500 company would definitely give more advantage in financial gain. But, working for non-profit would help you if you seek satisfaction in improving the wellness of others.

4 false

Each non-profit usually receive all forms of donation as long as the donation is relevant to their causes. For example, if the non-profit is established to help poor kids in Africa in their survival, materials such as foods, clothes, toys, books, or medicines would be accepted.

5. true

Non-profit organizations still pay tax on their income. But the rate usually would be significantly lower compared to other form of organizations. This happen because the government exempted non-profit organization from having to pay sales tax and property taxes from their operation.

6. D. $300 billion.

From united states alone, it is estimated that more than 390 billion dollar is given to charities each year.This number come from the combination of the contribution from Corporate’s Social responsibilities and the donations given by non-profit and individuals donators.

7. B. Not-for-profit” means the money that an organization earns goes to the organization to help it achieve its purpose rather than going to stockholders.

Not for profit organization usually established under a specific cause (such as hunger, environmental problems, etc). In for profit organization, the money form the operation would all be given to the shareholders. In non-profit organizations, the money from the operation would be allocated to fix the problems related to their cause.

8. C.20 – 50

People who donate the most to charities tend to be the people who are still in productive age. these people had higher amount of average income compared to other age groups. Because of this, they are the most likely to have more money on their reserve after fulfilling all of their consumptions.

9. A. .Improve your health, improve your self-confidence and help you become more satisfied with your life.

Studies shown that donating to charities contribute the reduction of stress which might lead to improvements to your health. The sense of self-satisfaction that come from charities would improve your self-confidence due to the perception that you’ve done good for others.

10. A.You may be able to write off your donation on your taxes.

Since they are considered as an act that had positive benefits to society, most governments in the world would consider charities that you’ve given as a tax write-off. This would be an upside for those who are genuinely willing to help. But on the down-side,  many people or corporations use this situation to manipulate their tax payments

The easiest way to solve this is to think about the number of times the digit 1 appears in each decimal place (ie, ones, tens, etc). 

Assuming the pages are numbered 1-500, then the digit 1 will appear in the ones place on page 1, 11, 21, … and so on, up to 491. So, every 10 consecutive integers, the digit 1 is in the ones place exactly once. To be more precise, it appears in 50 ones places. 

The digit 1 will appear in the tens place on pages 10,11, …, 19, 110, 111, …, 119, and so on. So in every 100 consecutive integers, the digit 1 is in the tens place exactly 10 times. If you count, it appears 50 times. 

Finally, the digit will appear in the hundreds place from pages 100-199, which is 100 pages. 

So the digit 1 appears 200 times.

Sodium chloride (NaCl) is an ionic solid. It dissolves easily in water. Which property of water allows it to dissolve NaCl?

Answer : The number of moles of hydrogen gas is, 0.033 mole

Explanation : Given,

Moles of sodium = 0.066 mole

The balanced chemical reaction will be,

2Na(s)+2H_2O(l)rightarrow 2NaOH(aq)+H_2(g)

From the balanced chemical reaction, we conclude that 2 moles of sodium  react with 2 moles of water to give 2 moles of sodium hydroxide and 1 mole of hydrogen has as a product.

As, 2 moles of sodium react to give 1 mole of hydrogen gas

So, 0.066 mole of sodium react to give frac{1}{2}times 0.066=0.033 moles of hydrogen gas

Therefore, the number of moles of hydrogen gas is, 0.033 mole

1. The right answer is B. Geosphere

The geosphere is usually called an earth’s sphere. The word thus names a phenomenon of the earth, which often lays shell-like around the whole celestial body. Within a period of 150 years, the geosphere term experienced at least ten different definitions, of which five are still used today in the German-speaking world. As a result, there is currently no agreement on the content, extent and extent of the geosphere.

2. The right answer is A. Biosphere

The biosphere is the system formed by all living things on planet Earth and their interrelations that influence the environment, as a medium on organisms. This meaning of “living envelope” of the Earth is the most widely used, but it sometimes refers to the space in which life develops.

3. The right answer is A. Atmosphere

The atmosphere is, in the broad sense, a gaseous layer that envelops some stars. The Earth as well as other planets or stars are provided. An atmosphere may contain particles in suspension (dust, aerosols, etc.) or reach very high temperatures, as is the case for stars, thus generating a light emission.

There are four variables which govern changes in population size.
births
deaths
immigration
emigration

A population gains individuals by birth and immigration and loses individuals by death and emigration.

Biotic Potential
Populations vary in their capacity to grow. The maximum rate at which a
population can increase when resources are unlimited and environmental
conditions are ideal is termed the population’s biotic potential. Each
species will have a different biotic potential due to variations in
the species’ reproductive span (how long an individual is capable of reproducing)
the frequency of reproduction (how often an individual can reproduce)
“litter size” (how many offspring are born each time)
survival rate (how many offspring survive to reproductive age)

There are always limits to population growth in nature. Populations
cannot grow exponentially indefinitely. Exploding populations always
reach a size limit imposed by the shortage of one or more factors such
as water, space, and nutrients or by adverse conditions such as disease,
drought and temperature extremes. The factors which act jointly to
limit a population’s growth are termed the environmental resistance. The interplay of biotic potential and density-dependent environmental resistance keeps a population in balance.
Carrying Capacity
For a given region, carrying capacity is the maximum number of
individuals of a given species that an area’s resources can sustain
indefinitely without significantly depleting or degrading those
resources. Determining the carrying capacities for most organisms is
fairly straightforward. For humans carrying capacity is much more
complicated. The definition is expanded to include not degrading our
cultural and social environments and not harming the physical
environment in ways that would adversely affect future generations.

For populations which grow exponentially, growth starts out slowly,
enters a rapid growth phase and then levels off when the carrying
capacity for that species has been reached. The size of the population
then fluctuates slightly above or below the carrying capacity.
Reproductive lag time may cause the population to overshoot the carrying
capacity temporarily. Reproductive lag time is the time required for
the birth rate to decline and the death rate to increase in response to
resource limits. In this scenario, the population will suffer a crash
or dieback to a lower level near the carrying capacity unless a large
number of individuals can emigrate to an area with more favorable
conditions. An area’s carrying capacity is not static. The carrying
capacity may be lowered by resource destruction and degradation during

changes.

An example of dieback occurred in Ireland after a fungus infection
destroyed the potato crop in 1845. During this potato famine
approximately 1 million people died and 3 million people emigrated to
other countries. Increased food production due to improved agricultural
practices, control of many diseases by modern medicine and the use of
energy to make historically uninhabitable areas of Earth inhabitable are
examples of things which can extend carrying capacity. The question is
how long will we be able to keep increasing our population on a planet
with finite size and resources?
