How to add and subtract mixed numbers?

To add or subtract mixed numbers, first convert them to improper fractions. Then, perform the addition or subtraction operation on the numerators while keeping the denominators the same. Next, simplify the resulting fraction if possible by reducing it to lowest terms. Finally, if needed, convert the improper fraction back to a mixed number for the final answer.

Round 0.34 to the nearest tenth?

Alright, honey, let's not make a big fuss over this. If you want to round 0.34 to the nearest tenth, it's pretty simple. The number 0.34 rounded to the nearest tenth is 0.3. Done and done.

What is extreme data?

There are three dimensions to Extreme Data - volume, velocity, and variety, - and management of these dimensions is critical when it comes to winning the battle for control of enterprise data amid the conflicting requirements of business intelligence and reporting vs. data mining and statistical analysis. Management of the data is often part of an Information Lifecycle Management strategy (ILM) or Nearline approach.

What is the product of w and 2?

The product of w and 2 is simply the result of multiplying w by 2. In mathematical terms, the product of two numbers is the result obtained when you multiply them together. So, the product of w and 2 can be expressed as 2w.

Is parallelogram a perpendicular sides?

No, a parallelogram does not have perpendicular sides by definition. A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. Perpendicular sides would form a right angle, which is a characteristic of rectangles, squares, and other types of quadrilaterals, but not parallelograms.

How many square meters is 10500 square feet?

Oh honey, let me break it down for you. 10500 square feet is equivalent to approximately 975.48 square meters. So you better start strutting in that space like you own it, because that's a whole lot of room to work with.

What is 2n x 3m?

Well, darling, 2n x 3m is the same as 6nm. It's like mixing peanut butter and jelly - they just go together like a match made in algebraic heaven. So, go ahead and multiply those variables like a math wizard on a mission.

What is a two step equation that equals 30?

A two-step equation that equals 30 could be 2x + 10 = 30. In this equation, you would first subtract 10 from both sides to isolate the variable: 2x = 20. Then, you would divide both sides by 2 to solve for x: x = 10. Therefore, the solution to the equation 2x + 10 = 30 is x = 10.

What is a shape w 5 sides called?

Ah, a shape with 5 sides is called a pentagon. Isn't that a lovely name? Just imagine all the beautiful things you can create with a pentagon in your artwork. Keep exploring and embracing different shapes, my friend.

Factors of 42: 1, 2, 3, 6, 7, 14, 21, and 42

Factors of 90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90

Common factors of 42 and 90: 1, 2, 3, and 6

Greatest common factor: 6

(Since it's the greatEST, it's the only.)

How do you write 1 billion to the power of 1 billion?

To write 1 billion (1,000,000,000) to the power of 1 billion, you would multiply 1 billion by itself 1 billion times. This number is so astronomically large that it would have 1 billion zeros after the 1. This number is practically impossible to write out in standard notation due to its sheer size and complexity.

How do you simplify x times 3?

Well, honey, to simplify x times 3, you just multiply them together. So, the answer is 3x. It's as simple as that, darling.

What is the LCM of 11 3 and 2?

The Least Common Multiple (LCM) of 11, 3, and 2 is the smallest multiple that all three numbers share. To find the LCM, you need to first find the prime factors of each number: 11 is a prime number, 3 = 3, and 2 = 2. Then, you take the highest power of each prime factor that appears in any of the numbers: 11^1 x 3^1 x 2^1 = 66. Therefore, the LCM of 11, 3, and 2 is 66.

What is 69 over 92 reduced to its lowest terms?

To reduce the fraction 69/92 to its lowest terms, we need to find the greatest common divisor (GCD) of 69 and 92, which is 23. Dividing both the numerator and denominator by 23 gives us 3/4. Therefore, 69/92 reduced to its lowest terms is 3/4.

100,000 sides= decimyriagon/100,000-gon

1,000,000 sides= hecatommyriagon/1,000,000-gon

Since there are infinitely many polygons, it is impossible to list the names of all of them.

What is 1x10 to the power of 14?

1 multiplied by 10 to the power of 14 is equal to 10,000,000,000,000,000. This is because when you raise 10 to the power of 14, you are essentially adding 14 zeroes to the number 10. So, 1 multiplied by 10 with 14 zeroes is 10 quadrillion.

What is the circumference of a circle if the radius is 4 inches?

The circumference of a circle can be calculated using the formula C = 2πr, where r is the radius of the circle. In this case, if the radius is 4 inches, then the circumference would be C = 2 x π x 4 = 8π inches, or approximately 25.13 inches.

331 students went on a field trip six buses were filled and 7 students traveled in cars how many students were in each bus?

To find out how many students were in each bus, we first subtract the students who traveled in cars from the total number of students: 331 - 7 = 324 students. Then, we divide the remaining students by the number of buses to determine how many students were in each bus: 324 students / 6 buses = 54 students in each bus.

Why is x the most common variable?

x is the most common variable because x is usually used as a sign that signals that of a question. "x" is two diagonal lines, crossing out the wrong answer. which is a question, if someone doesn't know the right answer, they will most likely answer it wrong. So, gradually, "x" is "i don't know." so, that is marked or used as an unknown character.
