question:f a zoo has 21 penguins and twice as many polar bears, what is the total number of animals in the zoo?
answer:If the zoo has 21 penguins, and twice as many polar bears, then the number of polar bears is 21*2 = 42 The total number of animals in the zoo is the sum of the number of penguins and polar bears, so it is 21+42 = 63 63 The answer is: 63
question:Determine the 100th digit after the decimal point in the decimal representation of 1/7.
answer:To find the decimal representation of 1/7, we can perform long division. Note that the remainder repeats after every division step, and that the decimal representation of 1/7 is a repeating decimal. The first few digits after the decimal point are 0.142857142857... Since the remainder repeats every 6 digits, the 100th digit after the decimal point is the same as the 4th digit after the decimal point, which is boxed{8}. The answer is: 8
question:What is the height of a papaya tree when it is 5 years old, considering that it grows 2 feet in the first year, 50% more in the second year, 50% more than the second year in the third year, twice as much as the third year in the fourth year, and half as much as the fourth year in the fifth year?
answer:In the first year, the tree grows 2 feet. In the second year, it grows 2 + 2 x 50% = 2 + 1 = 3 feet. In the third year, it grows 3 + 3 x 50% = 3 + 1.5 = 4.5 feet. In the fourth year, it grows 4.5 x 2 = 9 feet. In the fifth year, it grows 9 / 2 = 4.5 feet. Therefore, the height of the papaya tree when it is 5 years old is 2 + 3 + 4.5 + 9 + 4.5 = 23 feet. 23 The answer is: 23
question:Stormi is saving up to buy a bicycle. She washes 3 cars for 10 each. She mows 2 lawns for 13 each. If the bicycle she wants costs x, how much more money does Stormi need to make to afford the bicycle? If we know the answer to the above question is 24, what is the value of unknown variable x?
answer:Stormi washes 3 cars for 10 each, so she earns 3 * 10 = 30. She mows 2 lawns for 13 each, so she earns 2 * 13 = 26. The total amount of money she earns is 30 + 26 = 56. She wants to buy a bicycle that costs x, so she needs to make x - 56 more. We are given that she needs to make 24 more, so we can write: x - 56 = 24. Adding 56 to both sides, we get: x = 80. The value of x is 80. 80 The answer is: 80
