Percent And Ratio Smarts

Having trouble with percents and ratios? With a clear and simple style, Lucille Caron and Phil St. Jacques help students get a handle on percents and ratios. They will learn reduce ratios, find equivalent ratios, and the relationship of ratios and proportion. Then they will learn the meaning of percents, and how they relate to fractions and ratios. Calculation techniques are clearly explained and many examples are included throughout the book. Whether you are looking to learn this information for the first time, on your own or with a tutor, or you would like to review your math skills, this book will be a great choice.

This essential volume explores test-taking tips and hints as readers learn how to solve multiple choice, short-answer, and show-your-work questions. Author Rebecca Wingard-Nelson introduces all the skills readers need to know to ace their percents and ratios test questions. Free worksheets are available on enslow.com.

“p>Building wealth is about managing our careers and the money we make. It all starts with the understanding that we build wealth primarily for two reasons: 1) to build prosperity and 2) to afford a comfortable retirement. Saving and investing to build prosperity is what we do to improve the quality and independence in our lives. Each of us measures quality and independence in our own terms-to some it means being able to afford big-ticket expenses, such as a dream home or supporting a favorite charity. To others it might mean making money work for us so that we don't have to work for it. We save and invest for retirement because, at some point in the future, we will choose to stop working and will need to replace the salary we currently earn. Saving and investing to afford a comfortable retirement is an obligation we have to ourselves. It is important to realize that we have no choice but to get on track saving and investing for retirement. We will be depending on it for survival in the later years of our life-considering how much longer people live with every passing decade, saving and investing is becoming increasingly more important.

This book comprises select proceedings of the international conference ETAEERE 2020, and primarily focuses on renewable energy resources and smart grid technologies. The book provides valuable information on the technology and design of power grid integration on microgrids of green energy sources.

Over the last decade, law enforcement agencies have engaged in increasingly intrusive surveillance methods, from location tracking on cell phones to reading metadata off of e-mails. As a result, many believe we are heading towards an omniscient surveillance state and irrevocable damage to our privacy rights. In Smart Surveillance, Ric Simmons challenges this conventional wisdom by taking a broader look at the effect of new technologies and privacy, arguing that advances in technology can enhance our privacy and our security at the same time. Rather than focusing exclusively on the rise of invasive surveillance technologies, Simmons proposes a fundamentally new method of evaluating government searches - based on quantification, transparency, and efficiency - resulting in a legal regime that can adapt as technology and society change.

The poor health of today's roads--a subject close to the hearts of motorists, taxpayers, and government treasurers around the world--has resulted from faulty incentives that misdirect government decision-makers, according to the contributors to Street Smart. During the 1990s, bad government decision-making resulted in the U.S. Interstate Highway System growing by only one seventh the rate of traffic growth. The poor maintenance of existing roads is another concern. In cities around the world, highly political and wasteful government decision-making has led to excessive traffic congestion that has created long commutes, reduced safety, and caused loss of leisure time.Street Smart examines the privatization of roads in theory and in practice. The authors see at least four possible roles for private companies, beyond the well-known one of working under contract to design, build, or maintain governmentally provided roads. These include testing and licensing vehicles and drivers; management of government-owned facilities; franchising; and outright private ownership. Two chapters describe the history of private roads in the United Kingdom and the United States. Contemporary examples are provided of road pricing, privatizing, and contracting out are evident in environs as diverse as Singapore, Southern California, and Scandinavia, and cities as different as Bergen, Norway, and London, England. Finally, several chapters examine strategies for implementing privatization. The principles governing providing scarce resources in free societies are well known. We apply them to such necessities as energy, food, and water so why not to "road space"? The main obstacle to private, or semi-private, ownership of roads is likely to remain the reluctance of the political class to give up a lucrative source of power and influence.Those who want decisions about road services to be controlled by the interplay of consumers and suppliers in free markets, rat

The most punitive era in American history reached its apex in the 1990s, but the trend has reversed in recent years. Smart on Crime: The Struggle to Build a Better American Penal System examines the factors causing this dramatic turnaround. It relates and echoes the increasing need and desire on the part of actors in the American government system to construct a penal system that is more rational and humane. Author Garrick L. Percival points out that the prison boom did not naturally emerge as a governmental response to increasing crime rates. Instead, political forces actively built and shaped the growth of a more aggressive and populated penal system. He is optimistic that the shifting political forces surrounding crime and punishment can now reform the system, explaining how current political actors can craft more constructive and just policies and programs. The book shows how rationality and humanitarianism lead to a penal system that imprisons fewer people, does less harm to the lives of individual offenders and those close to them, and is less expensive to maintain. The book presents empirical data to concretely demonstrate what is working and what is not in today’s penal system. It closely examines policies and practices in Texas, Ohio, and California as comparative illustrations on what progress has been made or needs to be made in penal systems across the United States. The book includes a comprehensive discussion of highlighted issues, and relates more than two dozen interviews with pivotal political actors who clarify why there is a major shift underway in the American penal system. Their insights reveal paths that can be taken to improve the current penal system.
