This is a simple mathematical calculation that assess your understanding ability. Here the person is weighing 4 combinations every time and get an average of 500. This means that the weight must be around the value. On the other hand, the combined weight can never be 375 as it is less than the average. Hence, the total weight must be 750. You can calculate it by simply deducing the individual factors in and to create the perfect balance and estimating what the value can be. You may also use a complex formula to find the actual value for yourself also.

Many politicians want to become senators or representatives eventually. This is because they want to be able to make laws for their constituents. Congress is this group of people who represent their area around the country where they came from. They represent these groups of people who live in that area. Congress is divided into two sides. One side is called the House of Representatives. These representatives represent their state, and the number of representatives in the House depends on the population of the state. The higher the population, the more representatives come from that state. There are 435 representatives. In the Senate, two senators are elected from each state. Therefore, 100 senators represent the 50 states in the United States.

This is an example of a question that seeks to befuddle by providing extraneous information. Simon's journey is 50% longer than Danni's. Taking her leaving and arrival times you see that her journey takes one hour and ten minutes. Half this amount is 35 minutes. Add that time to Danni's arrival time, and you get to 4.00 so B is the correct answer here.

Information quality is ensured when measures to protect it are an integral part of its collection, use, storage, retrieval, and exchange.In this case storage of the collected information was placed into a wrong file.Data integrity strategies should provide safeguards against data manipulation or deletion, and entry of fraudulent facts.Hebda, Toni Lee; Czar, Patricia.

First of all, you should know that ISBN means International Standard Book Number. This is often used as the identifier for the books that you will see not only in the library but also online. You may take more notice of this now that you know what it stands for. ISBN 10 is assigned to different books that were published before the year 2007. Take note that you will gain more details about the ISBN 10 book if you would check out its four sections. The details will give you an idea if the book will provide the details and information that you are searching for. ISBN 13 will be assigned to books that are published after 2007, and it will also have more sections as compared to the ISBN 10.

Are you familiar with the robotyrannus and the roboreptile? Some people may assume that these are animals that lived long before humans started to inhibit the earth. These are actually toys that were both released in the year 2006. Kids often had to choose between the two because they have the same features and they also have other characteristics that make them very similar to each other. The codes of these two toys are different from each other. Roboreptile has the code 8065 and the code of Robotyrannus is 8063. There are also some differences with their physical features. People can often choose which one they like based on how these toys look like.

The correct answer to this question is D, 47. This questions has to do with averages.In relation to mathematics, an average is defined as a calculated central value of a set of numbers (in this example it is the entire weight of the class). Here is the math equation: let number of students in the class be n Average weight of the class is x Total weight of the class = nx If one student (50 kg) joins, comparing total weight of the class, illustrated as (n+1)(x+1) = nx + 50 If second student (50 kg) joins, comparing total weight of the class, then: (n+2)(x+1.5) = nx + 100 Solve: n + x = 49 - (1) 1.5n + 2x = 97 - (2) From (1), n = 49 - x Putting in (2) we get 73.5 + 0.5 x = 97 Thus we get 47: 0.5x = 23.5 or x = 47

Zero and nothing are two completely different things. Zero is known to be a number that is commonly written before the number 1 when counting numbers. Zero will also signify that there are other numbers that may take its position depending on what is being counted. This is considered to be one of the most important numbers in Mathematics and other aspects that are related to Math even if it may not seem obvious in the beginning. Nothing is different. Nothing can refer to your feelings, space, a situation, and so much more. You may be asked how you feel about something and you may say that it is nothing. This is considered to not have any beginning and nobody has seen its end just yet.

The correct answer to this question is C,10 liters. This questions has to do with averages.In relation to mathematics, an average is defined as a calculated central value of a set of numbers. This average is based onthe two solutions of sulphuric acid (acid+ water) with concentration of 50% and 80% respectively. Here is the math equation: 0.62 = [.50xn1 + .80 x n2] /[n1 + n2] –> 0.62 n1 + 0.62 n2 = .5 n1 + .8 n2 –> .12 n1 = .18 n2 –> 2 n1 = 3 n2 –> n1/n2 = 3/2 ………(i) n3=(n1 + n2) litres of 62 % acid sol. is mixed with 6 lit of water (pure water is used so concentration of it is 0% --it doesnt contain any sulphuric acid at this stage). .50 = [.62 x n3 + 0 x 6] /[n3 + 6] .5 n3 + 3 = .62 n3 –> .12 n3 = 3 –> n3 = 300/12 –> n3 = 25 lit. –> n1 + n2 = 25 putting n1= (3/2).n2 from (i) (3/2).n2 + n2 = 25 Then we arrive at the answer –> 5/2 . n2 = 25 –> n2 = 10 lit.

True. For example, -Pi is anirrational number. So negative numbers can be an irrational number
