A 5-digit number that is divisible by 9 must have its digits sum to a multiple of 9. The smallest 5-digit number that fits this criterion is 10,008 (1 + 0 + 0 + 0 + 8 = 9). Other examples include 10,017, 10,026, and so on, up to the largest 5-digit number that is divisible by 9, which is 99,999.

A dodecahedron is a polyhedron with 12 pentagonal faces. Each pentagon has internal angles that sum up to 540 degrees. Therefore, the sum of all the angles in a dodecahedron can be calculated by multiplying 540 degrees by the number of faces, which is 12. This results in a total sum of 6480 degrees.

Need the angle between those two sides, or some more info.

Imagine taking a 1 inch tooth pick and a 2 inch toothpick. Now line up the tips and you

can make tons of angles. If you joined the outer tips of your toothpicks you would have a triangle. Can you see that you can have many different sides lengths depending on the angle between them?

Since we always say that x equals the number 1, because we can assume that the equation is 1 + 1. So the answer is 2.

To find the area of a square with a diagonal of 14, we first need to determine the length of one side of the square. Using the Pythagorean theorem, we can calculate that the side length is 7√2. Then, we can find the area of the square by squaring the side length, which gives us 98 square units.

To find 2 times the sum of x and y, you first need to calculate the sum of x and y by adding the two variables together. Once you have the sum, you multiply it by 2 to get the final result. In mathematical terms, the expression for 2 times the sum of x and y can be written as 2(x + y).

In standard form, the number 12 is written as 1.2 x 10^1. This representation is achieved by moving the decimal point one place to the left and indicating the power of 10 needed to return to the original value. This format is commonly used in scientific notation to express large or small numbers more efficiently.

Well, isn't that a happy little question! Dividing a number "n" by 8 is like sharing a delicious cake with 8 of your friends. You simply take the total amount, "n," and divide it equally into 8 parts. Just remember to take your time, be gentle with your calculations, and enjoy the process of sharing and understanding numbers.

Well, isn't that just a happy little saying! You see, a triangle is made up of three sides and three angles, which gives it stability and rigidity. Unlike other polygons that can change shape or collapse, a triangle always keeps its form, just like a strong foundation in a painting. So, remember, just like a triangle, stay true to your values and beliefs, and you'll stand strong no matter what challenges come your way.

When you calculate (-20) plus (+8) by finding 20-8 and taking the opposite of the result, you are essentially using the concept of adding a negative number. By subtracting 8 from 20, you get 12. Taking the opposite of 12 gives you -12, which is the same as adding -12 to -20. This method follows the rules of arithmetic and helps simplify the calculation by converting it into a subtraction problem.

7.324 = (7 x 1) + (3/10) + (2/100) + (4/1000)

Well, honey, 40 ounces is the same as 2.5 pounds. So if you want to write that as a mixed number, it would be 2 1/2 pounds. Just divide those ounces by 16 (because there are 16 ounces in a pound) and you'll have your answer.

16 goes into 72 4 times with a remainder of 8 or 4.5 times

0.32 is greater than 0.3. When determining which decimal is greater, first look at the first digit after the decimal point to see which is larger. If they're the same (like in this case) move to the second digit. If there is no digit (as in the case of 0.3), assume that it's zero. Since 2 is larger than 0, that makes 0.32 larger than 0.30.

Well, isn't that just a happy little question! To find the diameter of a circle, you can use the formula: diameter = circumference / π. So, for a circle with a 128ft circumference, the diameter would be 128 / π ≈ 40.77 feet. Just imagine that circle as a lovely little friend, perfectly round and ready to bring joy to your day!

In expanded form, the number 1730002 can be expressed as: (1 x 1,000,000) + (7 x 100,000) + (3 x 10,000) + (0 x 1,000) + (0 x 100) + (0 x 10) + (2 x 1). This breaks down the number into its constituent place values, making it easier to understand the value of each digit within the number.

Oh, dude, you're hitting me with the math questions, huh? So, a number that's a factor of 1000 but not 10000 and is a multiple of both 50 and 8... Well, 40 fits the bill. It divides into 1000, but not into 10000, and it's the product of 50 and 8. Math can be fun, right?

The greatest common factor (GCF) of two numbers is the largest number that divides evenly into both numbers. In this case, the factors of 55 are 1, 5, 11, and 55. The factors of 5 are 1 and 5. The greatest common factor of 55 and 5 is 5, as it is the largest number that divides evenly into both 55 and 5.

Oh, dude, 0.9kg is actually smaller than 850g. I know, right? It's like comparing apples to oranges, but in this case, it's more like comparing grams to kilograms. So yeah, 0.9kg is technically less than 850g. Mind-blowing, I know.

The resolution 640x480 refers to a display or image that is 640 pixels wide and 480 pixels tall. To find the total number of pixels, you multiply the width by the height. In this case, 640 multiplied by 480 equals 307,200 pixels.
