Let's denote the cost of each carton of ice cream as \( x \) dollars. Caleb bought 10 cartons of ice cream, so the total cost for the ice cream is \( 10x \). Each carton of frozen yoghurt costs $1, and Caleb bought 4 cartons, so the total cost for the frozen yoghurt is \( 4 \times 1 = 4 \) dollars. According to the ...

To find the number of multiples of 9 less than 80, we can divide 80 by 9 and take the integer part of the result. 80 ÷ 9 = 8.888... The integer part of the result is 8, which means there are 8 full multiples of 9 within the range of numbers less than 80. However, we need to list them out to ensure we are not includin...

Rotating $360^\circ$ is the same as doing nothing, so rotating $600^\circ$ is the same as rotating $600^\circ - 360^\circ = 240^\circ$. Therefore, we have $\sin 600^\circ = \sin (600^\circ - 360^\circ) = \sin 240^\circ$. Let $P$ be the point on the unit circle that is $240^\circ$ counterclockwise from $(1,0)$, and le...

If you multiplied the number by 8 and got 56, we can find the original number by dividing 56 by 8: 56 / 8 = 7 Now, to find the correct result when you divide this number by 8, we do the following calculation: 7 / 8 = 0.875 To the second decimal place, the correct result is 0.88.

To find the value of the certain number, we can set up the equation: 82.04 ÷ certain number = 28 To solve for the certain number, we can rearrange the equation: certain number = 82.04 ÷ 28 Now we can perform the division: certain number = 2.93 So, the value of the certain number is 2.93.

Let's call the number we are looking for "x". According to the problem, when we subtract 36 from x and then multiply the result by 22, we get 748. We can write this as an equation: 22 * (x - 36) = 748 Now, let's solve for x: First, divide both sides of the equation by 22 to isolate the term (x - 36): (x - 36) = 748...

Dividing both sides of the inequality by 1.2, we have $t \le \dfrac{9.6}{1.2}$. The right side of this inequality is equal to $\dfrac{96}{12}$, which is $8$. Thus, we are looking for the sum of all positive integers less than or equal to $8$. This is $1+2+3+4+5+6+7+8 = \boxed{36}$.

Let's denote the number of pieces of colored paper used for making a piece of art as x. According to the problem, the number of colored paper left is 6 less than x, which can be written as x - 6. We know that Seokgi started with 82 sheets of colored paper. After using x sheets for the art, the remaining sheets would b...

To merge the two arrays in O(n log n) time complexity using the merge sort algorithm, we can follow these steps: 1. Implement the merge function: This function takes in two sorted arrays and merges them into a single sorted array. It uses two pointers, one for each array, to compare elements and merge them in ascendin...

One possible data structure that can efficiently store and retrieve the required information is a combination of a Max Heap and a Balanced Binary Search Tree (BBST). 1. Max Heap: Store the countries and their population as nodes in a Max Heap. The population of each country will be the key for comparison purposes. Thi...

By the quadratic formula, the roots of the equation are $$x=\frac{-(99)\pm\sqrt{(99)^2-4(\frac12)c}}{2(\frac12)},$$which simplifies to $$x=-99\pm\sqrt{9801-2c}.$$This looks like our target, except that we have to get the $9801-2c$ under the radical to equal $8001$. So, we solve the equation $9801-2c=8001$, which yields...

To place the numbers in ascending order, we need to start with the smallest number and progress to the largest. Comparing the given numbers: 2.23, 3.12, 9.434, and 2.453 We can see that 2.23 is the smallest number among them. Therefore, 2.23 should come first in the ascending order.
