the first day anna read a quarter of the book. on the second day she read a third of the remainder. noticed that after two days he had 80 pages left unread. how many pages did the book have?​

Answers

Answer 1

Answer:

160 pages

Explanation:

[tex]Day\ 1 = \frac{1}{4}[/tex]

[tex]Day\ 2 = \frac{1}{3}Remainder[/tex]

[tex]Left = 80[/tex]

Required

The number of pages

Let the number of pages be x.

So, on day 1; we have:

[tex]Day\ 1 = \frac{1}{4}x[/tex]

After day 1, there are:[tex]\frac{3}{4}x[/tex] left ----------------- i.e x - 1/4x

On day 2, we have:

[tex]Day\ 2 = \frac{1}{3} * \frac{3}{4}x[/tex]

[tex]Day\ 2 = \frac{1}{4}x[/tex]

At this point, we have:

[tex]Day\ 1 = \frac{1}{4}x[/tex]

[tex]Day\ 2 = \frac{1}{4}x[/tex]

[tex]Left = 80[/tex] ---- pages left

The summation of all must equal x, the book pages

[tex]Day\ 1 + Day\ 2 + Left = Total\\[/tex]

[tex]\frac{1}{4}x + \frac{1}{4}x+ 80= x[/tex]

Simplify the left-hand side

[tex]\frac{1}{2}x+ 80= x[/tex]

Collect like terms

[tex]x - \frac{1}{2}x= 80[/tex]

Simplify

[tex]\frac{2-1}{2}x= 80[/tex]

[tex]\frac{1}{2}x= 80[/tex]

Multiply by 2

[tex]2 * \frac{1}{2}x= 80*2[/tex]

[tex]x = 160[/tex]

describe what impact your personal vision could have your community or on society​

Answers

A personal vision statement is a mission statement of what you want to accomplish in your life, both personally and professionally. This statement can be used as a guide when determining the career to pursue, making important life decisions, planning how you'll accomplish goals, and realizing your life dreams.

My personal vision will have a positive impact on my community by solving the problems around my community and my society at large.

What is a personal vision?

A personal vision is a written description of your goals, strengths, and ambitions. It could perhaps be oriented towards one's long-term aspirations and could be focused on life or career goals.

As an educationist, my vision, persistence, and determination to study stem from a desire to excel in my work as an educator, as well as to inspire and serve as a role model for my community and the world at large.

Growing up in a typical setting taught me about the effects of educational reform on livelihood, economics, environment, and human existence. I learned as a youngster the bad consequences of not being educated and being illiterate owing to the fact that people cannot just afford the high cost of learning.

Since then, I've dedicated my life to educating the public and teaching students in my community and society as a whole. My vision is to raise awareness of the negative consequences of illiteracy in our society and to promote action to combat it by giving free education to students and the general public.

What audience are you thinking of targeting for the game you will design? Are you targeting an age group, an interest group, or a different kind of group? Describe your audience in detail, explaining why you think they would like to play your game.
please help me

Answers

Answer:

an interest group

Explanation:

When designing a video game I believe that the best target group would be an interest group. Focusing on a specific interest group will allow you to design a game, knowing that there are people truly passionate about that interest and who will play the game. Targeting an age group makes things difficult because you have to limit your creativity to that age group and even still there may not be much interest in that age group for your category of game. Therefore, an interest group is the best option and gives you the freedom to unlock your creativity without having to limit your game due to age concerns.

. Create a java File call Sales.Java contains a Java program that prompts for reads in the sales for each of 5 salespeople in a company. It then prints out the id and amount of sales for each salesperson and the total sale. 2. Compute and print the average sale. 3. Find and print the maximum and minimum sale. 4. After the list, sum, average, max and min have been printed, ask the user to enter a value. Then print the id of each salesperson who exceeded that amount, and the amount of their sales. Also print the total number of salespeople whose sales exceeded the value entered. 5. Instead of always reading in 5 sales amounts, in the beginning ask the user for the number of sales people and then create an array that is just the right size. The program can then proceed as before

Answers

Answer:

The program is as follows:

import java.util.*;

public class Sales{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 int salesPeople;

 System.out.print("Number of Sales People: ");

 salesPeople = input.nextInt();

 int[] salesID = new int[salesPeople];

 float[] salesAmount = new float[salesPeople];

 float total = 0;

 for(int i = 0; i<salesPeople;i++){

     System.out.print("ID: ");      salesID[i] = input.nextInt();

     System.out.print("Amount: ");      salesAmount[i] = input.nextFloat();

     total+=salesAmount[i];  }

 System.out.println("ID\t\tAmount");

 for(int i = 0; i<salesPeople;i++){

     System.out.println(salesID[i]+"\t\t"+salesAmount[i]);  }

 System.out.println("Total Sales: "+total);

 System.out.println("Average Sales: "+total/salesPeople);

 Arrays.sort(salesAmount);

 System.out.println("Minimum Sales: "+salesAmount[0]);

 System.out.println("Maximum Sales: "+salesAmount[salesPeople-1]);

 float sales;

 System.out.print("Print records that exceed: ");      sales = input.nextFloat();

Answer:

I hope This will help you... Please mark me as Brilliant

Please

Explanation:

You want to make sure you prepare thoroughly before starting a business, but realize that things will almost certainly go awry. To run a successful business, you must adapt to changing situations.

Conducting in-depth market research on your field and the demographics of your potential clientele is an important part of crafting a business plan. This involves running surveys, holding focus groups, and researching SEO and public data.

Before you start selling your product or service, you need to build up your brand and get a following of people who are ready to jump when you open your doors for business.

This article is for entrepreneurs who want to learn the basics steps of starting a new business.

Tasks like naming the business and creating a logo are obvious, but what about the less-heralded, equally important steps? Whether it's determining your business structure or crafting a detailed marketing strategy, the workload can quickly pile up. Rather than spinning your wheels and guessing at where to start, follow this 10-step checklist to transform your business from a lightbulb above your head to a real entity.

1. Refine your idea.

If you're thinking about starting a business, you likely already have an idea of what you want to sell online, or at least the market you want to enter. Do a quick search for existing companies in your chosen industry. Learn what current brand leaders are doing and figure out how you can do it better. If you think your business can deliver something other companies don't (or deliver the same thing, only faster and cheaper), or you've got a solid idea and are ready to create a business plan. 

Define your "why."

"In the words of Simon Sinek, 'always start with why,'" Glenn Gutek, CEO of Awake Consulting and Coaching, told Business News Daily. "It is good to know why you are launching your business. In this process, it may be wise to differentiate between [whether] the business serves a personal why or a marketplace why. When your why is focused on meeting a need in the marketplace, the scope of your business will always be larger than a business that is designed to serve a personal need." 

Consider franchising.

Another option is to open a franchise of an established company. The concept, brand following and business model are already in place; all you need is a good location and the means to fund your operation.

You are preparing to install Windows Server 2012 on a new server. The server has the following hardware: 2 TB RAM 16 64-bit Intel-VT processors 10 GB mirrored hard disk for the system partition You will use the server for the following server roles: File and Storage Services Print and Document Services Windows Deployment Services You want to select the minimum Windows Server 2012 edition to support the required roles and hardware. Which edition should you install

Answers

Answer:

The ideal edition of the Window you should install is Standard.

Explanation:

Customers that require a physical or moderately virtualized environment should choose the Standard edition. With each license, you may operate up to two virtual instances of Windows Server and get all of the same capabilities as the Datacenter edition. Standard version has the same processor plus CAL (Client Access License) licensing as Datacenter edition, with each license covering up to two physical processors on a single server.

With these features, the server is able to perform the roles file and storage services, print and document services, and Windows Deployment Services.

Therefore, the ideal edition of the Window you should install is Standard.

In cell L2, enter a formula using the IF and AND functions, as well as structured references to determine if Adam Moriarty can be a bunk leader. a. The logical test in the IF function should determine if the staff member’s Service Years is greater than 4 AND the staff member’s Leadership Training status is "Yes". Remember to use a structured reference to the Service Years and the Leadership Training columns. b. The function should return the text Yes if a staff member meets both of those criteria. c. The function should return the text No if a staff member meets none or only one of those criteria.

Answers

Answer:

Enter the following formula in L2

=IF(AND([Service Year]>4,[Leadership Training]="Yes"),"Yes","No")

Explanation:

Analyzing the formula:

[tex]= \to[/tex] Begin the formula with an equal to sign

IF [tex]\to[/tex] This indicates that the formula uses an "IF" function

AND [tex]\to[/tex] This indicates that there are at least 2 conditions in the function; all of which must be true for the function to return true.

The conditions in the formula are:

[Service Year]>4;  and [Leadership Training]="Yes"

Notice that the column names (service year and leadership training) are called and not the cell names (e.g. K2); this is what is referred to as structured referencing.

Having said that, both conditions must be true for the function to return true (because we use the AND clause to join both functions)

The possible results in the formula are:

"Yes","No"

If both conditions are true, then the value of L2 will be "Yes"

If otherwise, then the value of L2 will be "No"
