Two hundred ten balloons are filled for a reception. This is 70 percent of the entire number of balloons purchased. Which equation can be used to find the total number of balloons purchased?
StartFraction 210 divided by 3 Over 100 divided by 3 EndFraction = StartFraction 70 Over 33.3 EndFraction
StartFraction 70 times 3 Over 100 times 3 EndFraction = StartFraction 210 Over 300 EndFraction
StartFraction 100 divided by 3 Over 210 divided by 3 EndFraction = StartFraction 33.3 Over 70 EndFraction
StartFraction 70 times 3 Over 210 times 3 EndFraction = StartFraction 210 Over 630 EndFraction

Design an er diagram for keeping track of information about votes taken in the u.s. house of representatives during the current two-year congressional session. the database needs to keep track of each u.s. state's name (e.g., texas', new york', california') and include the region of the state (whose domain is {northeast', midwest', southeast', southwest', west'}). each congress person in the house of representatives is described by his or her name, plus the district represented, the start date when the congressperson was first elected, and the political party to which he or she belongs (whose domain is {republican', democrat', 'independent', other'}). the database keeps track of each bill (i.e., proposed law), including the bill name, the date of vote on the bill, whether the bill passed or failed (whose domain is {yes', no'}), and the sponsor (the congressperson(s) who sponsored - that is, proposed - the bill). the database also keeps track of how each congressperson voted on each bill (domain of vote attribute is {yes', no', abstain', absent'}). additional information:
