answer:To find the fraction of the original amount of popcorn left uneaten, let's break it down step by step. Initially, Jordan starts with a full bowl of popcorn. After half an hour, 1/3 of the popcorn is gone. This means 2/3 of the original amount remains. In the next half hour, Jordan eats 1/2 of what's left. Since 2/3 of the original amount was left after the first half hour, eating 1/2 of that is equivalent to eating 1/2 * 2/3, which is 1/3 of the original amount. So, after the second half hour, the amount eaten in that half hour is 1/3 of the original amount, and this is in addition to the 1/3 eaten in the first half hour. The total amount eaten is 1/3 + 1/3, which equals 2/3 of the original amount. Therefore, the fraction of the original amount of popcorn left uneaten is 1 - 2/3, which is 1/3.

answer:To find the probability of selecting a number that is not a perfect power, we first need to count the number of perfect powers from 1 to 150. Perfect squares from 1 to 150 are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, and 144, for a total of 12 numbers. Perfect cubes from 1 to 150 are 1, 8, 27, 64, and 125. Note that 1 and 64 are already counted in the perfect squares, so we add only 8, 27, and 125 to our list, for a total of 3 additional numbers. The only perfect fourth powers from 1 to 150 are 1, 16, and 81, which are already counted in the perfect squares. The only perfect fifth power from 1 to 150 is 32, but there is no perfect sixth power. So, there are 12 + 3 = 15 perfect powers from 1 to 150. Since there are 150 numbers in total, the probability of selecting a number that is not a perfect power is 1 minus the probability of selecting a perfect power. This is (150 - 15) / 150, which simplifies to 135 / 150. Reducing the fraction 135 / 150 by dividing both numerator and denominator by their greatest common divisor, which is 15, we get 9 / 10. Therefore, the probability of selecting a number that is not a perfect power is 9 / 10.

answer:To find the total number of books that can be placed on the bookshelf, we need to multiply the number of shelves by the number of books that each shelf can hold. The bookshelf has 5 shelves, and each shelf can hold 8 books. Therefore, the total number of books that can be placed on the bookshelf is 5 * 8, which equals 40. So, 40 books can be placed on the bookshelf before it becomes completely full.
