82 * 183 + 105 – ? = 457

Answer: 14,654

To solve the equation 82 * 183 + 105 – ? = 457, follow the order of operations. First, perform the multiplication: 82 * 183 = 15006. Next, add 105: 15006 + 105 = 15111. The equation becomes 15111 – ? = 457. To find the unknown, subtract 457 from 15111: 15111 - 457 = 14654. Thus, the missing number is 14,654.

? * 8 / 2 = 116

Answer: 29

To solve the equation ? * 8 / 2 = 116, first simplify the division: 8 / 2 = 4. The equation then becomes ? * 4 = 116. To find the unknown, divide 116 by 4. Therefore, ? = 116 / 4 = 29. The missing number is 29.

4, 8, 2, 4, 1/6,?

Answer: 1/3

The pattern in the sequence 4, 8, 2, 4, 1/6, ? alternates between multiplication and division. The operations are: 4 * 2 = 8, 8 / 4 = 2, 2 * 2 = 4, 4 / 24 = 1/6. The multipliers are consistently 2, while the divisors are increasing multiples of 4 (4, then 24, which is 4 * 6). Following this pattern, the next operation should be multiplication by 2. So, 1/6 * 2 = 2/6 = 1/3.

1, 1, 4, 32, 384, ?

Answer: 6,144

To find the next number in the sequence 1, 1, 4, 32, 384, ?, we need to identify the pattern of multiplication. The sequence of multipliers is: 1 * 1 = 1, 1 * 4 = 4, 4 * 8 = 32, 32 * 12 = 384. The multipliers themselves follow a pattern: 1, 4, 8, 12. The difference between these multipliers is +3, +4, +4. Assuming the pattern of adding 4 continues, the next multiplier would be 12 + 4 = 16. Therefore, the next number in the sequence is 384 * 16 = 6144.

Jorge attends school from Monday through Friday. He attends 18 courses a week. He is late to one-fourth of his classes this week, and on Thursday, when he doesn't show up at all, he is marked absent. On Thursdays, he typically has two lessons. How many classes did Jorge show up late for?

Answer: 25%

The question asks specifically how many classes Jorge showed up late for, and the options are percentages. The problem states directly that 'He is late to one-fourth of his classes this week.' One-fourth, as a fraction, is equivalent to 25% when converted to a percentage. The information about his absence on Thursday is a distractor for this particular question.

Randy wants to get his family a hot tub. He has a $4,500 budget. The one he truly wants costs one-fifth more than his set spending limit. After looking around, he decides to purchase a used one that is $1,225 less expensive than the new one he wanted but was unable to afford. What amount of money did Randy spend on the used hot tub?

Answer: $4,175

First, calculate the cost of the new hot tub Randy wanted: it costs one-fifth more than his $4,500 budget. One-fifth of $4,500 is $900, so the new hot tub costs $4,500 + $900 = $5,400. Next, Randy buys a used one that is $1,225 less expensive than the new one. So, the cost of the used hot tub is $5,400 - $1,225 = $4,175. Randy spent $4,175 on the used hot tub.

Andromeda Aquila: Cygnus A:?

Answer: Orion

This is an analogy question. Andromeda and Aquila are both prominent constellations. Cygnus A is a well-known radio galaxy. To complete the analogy, we need another constellation. Among the given options, Orion is a famous constellation, fitting the pattern of celestial bodies. Nebula, Virgo A (a galaxy), and Supernovae (an event) do not fit the 'constellation' category.
