Endocrine At an airport, 25% of the flights arrive from within the state, 35% from out of state, and the rest from other countries. How many flights arrived from out of state if a total of 240 flights arrive? 84 Equation to find the percent of a number make the percentage a decimal (35% = 0.35 or 79% = 0.79) then forget the decimal and multiply the percentage by the number you are trying to get a percentage from (35 x 240 = 8,400) then move the answer back the same number of decimal points you had before which in this case would be two (8,400 to 84.00) 84 is your answer.

the country's best location for cold-weather testing projects. The passage implies that the "Icebox of the Nation" slogan Brings both dollars and recognition to International Falls The American newspaper columnist Art Buchwald wrote humor columns--first for the European edition of the New York Herald Tribune in the 1950s and later for the Washington Post. Rather than the stinging wit of some of his contemporaries, Buchwald's style was kindly. Every once in a while, however, his patience with a politician, institution, or policy would wear thin, and his readers would see another, less avuncular side. Art Buchwald's newspaper column was awarded a Pulitzer Prize for commentary in 1982. Over the course of his career he would write newspaper columns and publish books for half a century. One can infer from the passage that Art Buchwald's writing, when he nearly lost his patience, was dismissive One of a group of talented and sometimes ruthless, entrepreneurs, Andrew Carnegie, a Scottish immigrant, worked his way up from modest beginnings to become one the richest people in 19th century America. In 1873 he organized his own steel company in Pittsburg, and it soon dominated the industry. In 1901 he sold his holdings in the company for $480 million to banker J.P. Morgan. Carnegie believed that the wealthy are merely trustees of their money and are obligated to use their resources for the benefit of society. Convinced that the best way to improve the lives of others was to provide them with access to knowledge, Carnegie funded thousands of public libraries. By the time of his death in 1919, he had given away most of his fortune to support a variety of philanthropic causes. Which of the following phrases best characterizes the tone of this passage? Admiring of Carnegie for donating a large part of his wealth After hearing reports on the dangers of mercury vapor from silver fillings, many people have decided to have these fillings replaced with a nonmetal material. While researchers note that mercury levels are slightly higher in people with silver fillings than in people without silver fillings, it would take at least 100 fillings to reach an unsafe level of mercury. The passage implies that people with normal numbers of silver fillings
Are not at risk from mercury vapor The accumulation of tiny genetic changes could account for the vast differences between humans and chimpanzees, researchers recently reported. They found that less than 1.5 percent of the DNA found on a chromosome in chimps. But these small variations are far from the whole story. Eight-three percent of the chimpanzee chromosome 22 proteins are different from their human counterparts. This means that only 17 percent of the chromosome 22 genes are identical, indicating that the evolutionary gulf between humans and chimps is much wider than the 98.5 percent match DNA might appear to indicate. According to the paragraph, human beings Are less alike than the 1.5 percent difference their DNA suggests. In order for a human to hear a sound, many things have to happen. The first is that sound waves must travel through matter, such as air, to the outer ear, the sound waves travel through the ear canal and hit the eardrum, causing it to vibrate. This also causes vibration in the ossicles in the middle ear. These three bones, the smallest in the human body, are called the malleus (or hammer), the incus (or anvil), and the stapes(or stirrup). Their vibration amplifies the force of the sound waves and passes the sound information to the inner ear. The fluid in the inner ear, along with thousands of tiny hairs cells of the organ of Coti, then transmits nerve impulses through the cochlear to the brain. It is here that the nerve impulses are interpreted as sound. According to the passage, in what party of the body is the force of sound waves amplified? Ossicles Benjamin Franklin began his career as a political leader when he went to London in 1757 as an agent of the Pennsylvania Assembly. During Franklin's stay in London, Alex Wedderburn, the British Solicitor-General, accused Franklin of being a "true incendiary" to British rule. As if to confirm the truth of Wedderburn's statement, Franklin is reported to have obtained--possibly illegally--embarrassing letters written by Massachusetts Governor Hutchinson concerning how to maintain accusations, Franklin wrote, "Having been from my youth more or less engaged in public affairs, it had often happened to me in the course of my life to be censured sharply for the part I took in them." According to the passage, which of the following statements is correct? A pro-British governor wrote about limiting the liberties granted to colonists.
