Bill bought a new cellular phone. His monthly bill will be $34.99 each month which includes 100 minutes of use. Additional minutes will cost $0.23 per minute. Write an equation that represents the cost of the bill C in terms of m, which is the number of minutes used ABOVE the 100 that are included in the base price. a. C = 34.99(m – 100) + 0.23 c. C = 0.23m b. C = 0.23m + 34.99 d. C = 0.23(m – 100) + 34.99


Answer:

d. C = 0.23(m – 100) + 34.99

Step-by-step explanation:

Let C = X + Y, where

C = Cost of the bill in terms of m

X = First term of the equation

Y = Second term of the equation

X = add additional minutes to $ 0.23 minus the 100 minutes of use allocated.

X = 0.23 (m – 100)

Y = Base price monthly will be $ 34.99

Y = 34.99

C = X + Y

C = 0.23 (m – 100) + 34.99

Note: The only possible answer is 0.23 (m – 100) + 34.99, but we must assume that “m” is greater than or equal to 100, that is, Bill consumes at least his 100 minutes assigned by the base price.

Hope this helps!

Lisa wants to buy a phone card for $5. Company X charges $0.37 for the first minute and $0.08 for each additional minute. Company Y charges $0.52 for the first minute and $0.14 for each additional minute. If Lisa makes just one call, which phone company gives her more minutes for $5? How many more minutes? a. Company Y; about 29 minutes c. Company X; about 26 minutes b. Company X; about 29 minutes d. Company Y; about 26 minutes


Answer:

Option b

Step-by-step explanation:

Given that Lisa wants to buy a phone card for $5.

Company X charges $0.37 for the first minute and $0.08 for each additional minute.

ie. for t minutes charges are C(t) = 0.37+0.08(t-1)

Company Y charges $0.52 for the first minute and $0.14 for each additional minute.

for t minutes company Y charges

C(t) = 0.52+0.14(t-1)

If 5 dollar is spent, then for company A

t = frac{5-0.37}{0.08}+1 =58.875 minutes

For company B, for same 5 dollars,

t =frac{5-0.52}{0.14} =33

Company x gives about 26 minutes more

Option b

In italy about 74 of every 100 people use celular telephones. Write the fraction of celular phone users in italy. Then write it as a decimal.


Answer:  The correct option is (B) dfrac{sqrt{17}+sqrt{2}}{sqrt{17}+sqrt{2}}.

Step-by-step explanation:  We are given to select the correct fraction by which the following be multiplied to produce an equivalent fraction with a rational denominator.

F=dfrac{3}{sqrt{17}-sqrt2}~~~~~~~~~~~~~~~~~~~~~~~~(i)

We know that

to rationalize the denominator having radical terms, we multiply both numerator and denominator by a common term which contains the opposite sign before the radical term as in the original denominator.

In the given denominator, both terms are radical ones, so we can change the sign of any one of them and then multiply to the denominator and numerator simultaneously.

So, we will multiply both numerator and denominator by the term sqrt{17}+sqrt2.

From (i), we have

F\\=dfrac{3}{sqrt{17}-sqrt2}\\\=dfrac{3(sqrt{17}+sqrt{2})}{(sqrt{17}-sqrt{2})(sqrt{17}+sqrt{2})}\\\=dfrac{3(sqrt{17}+sqrt{2})}{17-2},~~~~~~~~textup{since}~(a+b)(a-b)=a^2-b^2\\\=dfrac{3(sqrt{17}+sqrt{2})}{15}\\=dfrac{sqrt{17}+sqrt{2}}{5}.

Thus, the denominator is rationalized and the required fraction to be multiplied is

dfrac{sqrt{17}+sqrt{2}}{sqrt{17}+sqrt{2}}.

Option (B) is CORRECT.

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! 🙂

Read the excerpt from The Code Book. More than a hundred million e-mails are sent around the world each day, and they are all vulnerable to interception. Digital technology has aided communication, but it has also given rise to the possibility of those communications being monitored. According to Zimmermann, cryptographers have a duty to encourage the use of encryption and thereby protect the privacy of the individual: A future government could inherit a technology infrastructure that’s optimized for surveillance, where they can watch the movements of their political opposition, every financial transaction, every communication, every bit of e-mail, every phone call. Everything could be filtered and scanned and automatically recognized by voice recognition technology and transcribed. It’s time for cryptography to step out of the shadows of spies and the military, and step into the sunshine and be embraced by the rest of us. In the excerpt, the purpose of the statistic “more than a hundred million e-mails” is to show that digital information is widespread and available to monitoring. most e-mails that are sent are not viewed by the government. encryption has been used by the military but not ordinary citizens. e-mail is a good way for people to communicate nowadays.


Answer:

Gather references, and prepare your résumé.

Explanation:

Before a job interview, it is advisable to prepare a copy of your résumé and references, as well as bring a pen and notepad.

The rest of the alternatives are incorrect because asking the company to keep your résumé on file is inappropriate – you should always carry a copy of  it; asking and answering questions politely happens during the course of the interview; and restating your interest is done after the interview has occurred.

I suggest that you dial the phone number again. The bolded words are what kind of clause?


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 🙂

In a multi-paragraph essay, explain how the activity of individual neurons enables you to perform a simple action like answering your phone. Be sure to describe the main parts of a neuron, explain the unique function of each part, and describe how neurons use electrochemical signals for neurotransmission. Include details from class materials, readings, and research on the nervous system to support your discussion.


There are two systems in the human body that are responsible for the coordination between the functions of different systems to achieve the unity of the living organism’s body. These two systems are the nervous system and the endocrine system. The action of the nervous system is fast and takes a short time, while the action of the endocrine system is slow and takes a long time.

The functional unit of the nervous system is the nerve cell or the neuron. The neuron consists of a cell body and the axon. The cell body starts with the dendrites that receive the messages or the impulses from other neurons or from different sense organs or receptors. These impulses are then transmitted through the cell body. The cell body contains a nucleus and different organelles which help the nerve cell to perform its functions. The nerve impulse is then transmitted to the axon.

The axon is an extension from the cell body. There are some cells called Schwan cells that secrete a myelin sheath to insulate the axon from the surrounding medium. The insulated axons have more ability to conduct the impulses than non-insulated axons. The axon ends with the terminal arborizations. The terminal arborizations of a nerve cell connect to the dendrites of the next cell or to the afferent organ. The gaps between the dendrites and the terminal arborizations are called the synapses.

The nerve impulse is an electrochemical phenomenon i.e. an electrical phenomenon with a chemical nature. The membrane of the axon acts as a barrier between an outside positively charged medium and an inside negatively charged medium. This makes a potential difference of  -70mV. This state is called the resting potential. When the membrane is subjected to a stimulus, the positive charges enter to inside and the negative charges exit to the outside. The potential difference now becomes +40mV. This state is called the depolarization state. The point of stimulation acts as a new stimulus for the next point and so on. The membrane sooner gains its permeability again and the positive charges return to the outside and the negative charges to inside. This state is called repolarization.

The nerve impulse reaches the synapse. There are some neurotransmitters that are excited by the nerve impulse coming and carry the message across the membrane. Some receptors receive theses neurotransmitters on the dendrites of the next neuron. These receptors act as a stimulus for the new cell.

1. The answer is “C”.

“Identical twins” who have been raised apart are typically more similar in intelligence level than biological siblings raised together because they have been born with the same genetic code.

Identical twins originate from a single fertilized egg that parts into two. Before it parts, it is either male or female. After it parts, there are either two guys or two females. The two sections of the fertilized egg embed in the uterus and every create one of the twins.  

Identical twins have the equivalent hereditary source. No immediate reason for monozygotic twinning has been resolved; it isn’t innate. Monozygotic twins speak to around 33% all things considered. They may look strikingly comparative, and it might be hard to reveal to them separated.

2. The answer is “A”.

Lawrence Kohlberg felt that one of the only ways individuals will accomplish the objectives in each of his six stages was to participate in “consensus democracy” in small group settings.

Lawrence Kohlberg felt that the best way to support development through these stages was by discourse of good problems and by investment in consensus democracy inside small groups. Consensus democracy was rule by understanding of the gathering, not larger part rule. This would invigorate and widen the reasoning of youngsters and grown-ups, enabling them to advance starting with one phase then onto the next.

3. The answer is “D.  showing a learner how to correct common mistakes”.

The term scaffolding alludes to a procedure in which instructors display or exhibit how to take care of an issue, and afterward venture back, offering support as required. Analyst and instructional architect Jerome Bruner first utilized the term ‘scaffolding’ in this setting, harking back to the 1960s. The hypothesis is that when understudies are given the help they require while discovering some new information, they stand a superior possibility of utilizing that learning freely. Bruner suggests positive association and three methods of portrayal amid educating: activities, pictures, and dialect.

Through unit-of-output method, the formula for depreciation is determined as 

Depreciation = (number of units sold/life of unit)(cost-salvage)

However, there is a missing value. The life of the unit is 5000 hours; the cost is $120,000; the salvage value or the residual value is $15000. There is no data for the number of machines produced in year 2. Technically, we cannot solve this problem. But let’s assume it’s 100,000 machines for sample purposes. Then, 

Depreciation = (100,000/5000)(120,000-15,000)
Depreciation = $2,100,000 per hour
