What are the cons of a mixed market economy for most citizens? CHECK ALL THAT APPLY.-There may be a sizable gap between rich and poor people.- It can be very difficult for citizens to start private businesses.- Citizens must pay for most basic necessities by themselves.- There is no guarantee of steady employment for many citizens.-Citizens may pay higher taxes than in other economic systems.O Citizens often purchase their own health care and higher education, solve the following equation3(y 2) + 2y = 9 does anyone know how to not be scared during a socratic seminar if its going to be graded ? plz help me with this Find the product of largest 4 digit number andsmallest 3 digit number. Hi could you help pls it is due tonight at 11:59 and its 10:47 Why were city planning and zoning a necessity in American cities? Solve each equation. Leave the answer as an improper fraction. 16x^2 = 49 Select the correct answer.Which two particles can form an ionic bond with each other?A. a negative oxygen ion and a negative chlorine ionB. a positive sodium ion and a positive magnesium ionC. a positive calcium ion and a negative oxygen ionD. a neutral fluorine atom and a negative sulfur ion 1/2 means that the voltage (or charge) of the system will increase to half more of what is left in a time equal to t1/2 seconds. Therefore if a system is already at half charge (t1/2 seconds after starting) then after t1/2 more seconds the system will be charged to 50% plus half of 50%. That is 25% more, or 75% of the entire charge. Let's say that four t1/2's have gone by. That means that the charge (or voltage) is at (50% + 1/2*50% + 1/2*1/2*50% + 1/2*1/2*1/2*50%) = 93.75% of maximum charge. Yikes! Now look in your manual for a more simple mathematical derivation of this concept. Given t1/2 to be 0.4406 seconds, how long should it take to reach 75% of maximum charge? answer in seconds. Write the equation 3x+2y=8 in general form. SHOW YOUR WORK PLEASE Who shot Alexander Hamilton?a. George Washingtonb. Thomas Jeffersonc. Philip Hamiltond.

You want to fill each pouch with of a cup of confetti, and you have a total of 210 fluid ounces of confetti. You need enough pouches for 120 guests.Which equation can you use to determine whether you have enough pouches for 120 guests?number of pouches = 210 + number of pouches = 210 number of pouches = 210 8 number of pouches = 210 8 number of pouches = 210 8 (6b+9)(6b+5)........ 13. Choose two sentences that explain how the use of IAFIS has changed the process of identifyfingerprints. LTD(2 Points)O Since its start in 1997, IAFIS has been improved with technology upgrades to the system.In the beginning, investigators used ink and paper to record a person's fingerprints.Then, they scanned them into the computer to be submitted to the database.Since 2001, a machine called Livescan has been used to scan fingerprints directly into IAFIS.Livescan cuts down on processing time.OThis makes the jobs of police and investigators much easier. simple math true and false. not that hard. 11th grade math though Which statement accurately describes the following passage?(1) Without a doubt, democracy is the best form of government. (2) Originally developed in ancient Greece, democracy as a form of government drew worldwide attention after the American Revolution created a democracy in place of the former British colonies.
