4, 8, 2, 4, 1/6,?
The first step is to divide each pair of integers in half. As a result, 4 is equal to 8 divided by 2, and 2 divided by 4 is equal to 1/6.
1, 1, 4, 32, 384, ?
The formula is x 1, x 4, x 8, x 12, x 16, meaning that each number is multiplied by four more times than the one before it.
Andromeda Aquila: Cygnus A:?
82 * 183 + 105 – ? = 457
Phase one: 15,006 + 105 – ? = 457
Phase two: ? = 15,006 + 105 – 457
Phase three: ? is 14,654
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?
Let's start by setting up an equation to represent the information given in the problem:
Let x be the price of the hot tub that Randy really wants.
According to the problem, this price is one-fifth (or 1/5) more expensive than Randy's maximum budget of $4,500:
x = 4,500 + 4,500/5
x = 5,400
However, Randy decides to buy a second-hand hot tub that costs $1,225 less than the one he wanted. So the price of the second-hand hot tub is:
x - 1,225 = 5,400 - 1,225
x - 1,225 = 4,175
Therefore, Randy spends $4,175 on the second-hand hot tub.
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?
Phase one: He has 18 classes but didn’t attend 2, meaning that he only attended a total of 16 classes that week.
Phase two: ¼ of 16 = 4 classes where he was late
Phase three: Convert this to a percentage = 25%
? * 8 / 2 = 116
Step one: 116 * 2 = 232
Step two: 232 / 8 = 29
