• which sentences most clearly use a formal style and tone? check all that apply. i agree with macgregor’s point that the chronometer allowed for the mapping of the world, and i don’t see how anyone can disagree. without the chronometer, the world would never have been accurately mapped, which would have hindered the development of efficient trade routes. the chronometer helped people around the globe get in the swing of things by setting a standard time. the chronometer kept good time. people set the chronometers to gmt. people kept to strict schedules. people thought about time differently. the chronometer is the most historically significant object discussed in macgregor’s book because it established the concept of global standard time.
  
• clarissa has a budget of $1,200 a month to spend for rent and food. she has already spent $928 this month. which inequality represents the amount she can still spend this month and remain within her budget? x greater-than 272 x less-than-or-equal-to 272 x less-than 272 x greater-than-or-equal-to 272
  
• why did the soviet government's transition to collectivization result in widespread starvation? peasants were not allowed to keep food until they met government quotas. collectivization new methods resulted in a slowdown in crop production. many people were forced out of jobs when farms turned to collectivization. the government punished former farm workers who refused industrial jobs.

• mrs. culland is finding the center of a circle whose equation is x2 + y2 + 6x + 4y – 3 = 0 by completing the square. her work is shown. x2 + y2 + 6x + 4y – 3 = 0 x2 + 6x + y2 + 4y – 3 = 0 (x2 + 6x) + (y2 + 4y) = 3 (x2 + 6x + 9) + (y2 + 4y + 4) = 3 + 9 + 4 which completes the work correctly? (x – 3)2 + (y – 2)2 = 42, so the center is (3, 2). (x + 3)2 + (y + 2)2 = 42, so the center is (3, 2). (x – 3)2 + (y – 2)2 = 42, so the center is (–3, –2). (x + 3)2 + (y + 2)2 = 42, so the center is (–3, –2).
  
• δjkl has j = 7, k = 11, and m∠j = 18°. complete the statements to determine all possible measures of angle k. triangle jkl meets the criteria, which means it is the ambiguous case. substitute the known values into the law of sines: startfraction sine (18 degrees) over 7 endfraction = startfraction sine (uppercase k) over 11 endfraction. cross multiply: 11sin(18°) = . solve for the measure of angle k, and use a calculator to determine the value. round to the nearest degree: m∠k ≈ °. however, because this is the ambiguous case, the measure of angle k could also be °.
