Math and Arithmetic

Math is the study of abstractions. Math allows us to isolate one or a few features such as the number, shape or direction of some kind of object. Then we can study what can be learned about the behavior of those features while ignoring everything else about the object.

What is the answer to 9-36x?

The expression (9 - 36x) represents a linear equation. It cannot be simplified further without specific values for (x). If you're looking to solve for (x), you would need additional information or an equation to set it equal to.

Why were staff likes improvement to musical notation?

Staff notation has been improved to enhance clarity and precision in musical communication. These improvements help musicians interpret rhythms, dynamics, and articulations more effectively, reducing ambiguity. Additionally, advancements like the use of color coding or more intuitive symbols can aid in learning and accessibility for performers of varying skill levels. Overall, these enhancements make music more approachable and easier to read.

Is 3 over 10 greater or less than 3 over 4?

Intuitively we know that 0.3 is less than 0.75. To prove it, we need to get common denominators for our fractions 3/10 and 3/4. Since both 10 and 4 divide equally into 20, I multiply each by a fraction that equals one, but syncs up the denominators as follows:

3/10 * 2/2 = 6/20

3/4 * 5/5 = 15/20

So we see that 3/4 [15/2] is more than twice 3/10 [6/20].

How do you do a 69 in sex?

There is different ways to do it, the way that is most common is for the woman to be on top of the male, getting her mouth in line with the male's penis, the man then gets the woman to move back a little to where they can both use their mouth on each other.

What number is equal to 275?

The number equal to 275 is simply 275 itself. It can also be expressed in various forms, such as 2.75 × 10² or as a fraction like 275/1. Additionally, it can be represented in Roman numerals as CCLXXV.

How many 16ths are in?

To determine how many 16ths are in a given quantity, divide that quantity by 1/16. For example, if you have 1 whole, there are 16 sixteenths in that whole. If you have a different quantity, simply multiply it by 16 to find the number of 16ths.

What is the highest number you can roll on a dice?

On a regular, six-sided die, the highest number you can roll is a 6.

Find the Circumference 2 x 3.14 x r?

The formula for the circumference of a circle is given by ( C = 2 \pi r ), where ( \pi ) is approximately 3.14 and ( r ) is the radius of the circle. To find the circumference, simply multiply 2, 3.14, and the radius ( r ). For example, if the radius is 5, the circumference would be ( C = 2 \times 3.14 \times 5 = 31.4 ).

Is 0.08 a perfect square?

No, 0.08 is not a perfect square. A perfect square is a number that can be expressed as the square of an integer. Since 0.08 equals ( \frac{8}{100} ) or ( \frac{2^3}{10^2} ), it does not result from squaring any integer.

How much is 746 watts in dollars and cents?

To convert watts to dollars and cents, you need to know the cost of electricity per kilowatt-hour (kWh). For example, if electricity costs $0.12 per kWh, then 746 watts (or 0.746 kW) used for one hour would cost approximately $0.09 ($0.12 x 0.746). The actual cost will vary depending on your local electricity rates.

What basic mathematics rule do the functions follow?

Functions in mathematics generally adhere to the rule of consistency, meaning that for a given input, a function will always produce the same output. This is often summarized by the definition of a function as a relation that assigns exactly one output value for each input value from its domain. Additionally, functions can be combined using operations such as addition, subtraction, multiplication, and division, while also following the properties of arithmetic and algebra.

Why is x2 always negative for any nonzero value for x?

The statement that ( x^2 ) is always negative for any nonzero value of ( x ) is incorrect. In fact, ( x^2 ) is always non-negative for any real number ( x ). When ( x ) is nonzero, whether positive or negative, squaring it results in a positive value. Thus, ( x^2 ) is greater than zero for all nonzero ( x ).

What mark indicates foot?

The mark that indicates a foot is typically a foot symbol (℉) or the abbreviation "ft." In measurements, one foot is equal to 12 inches. In some contexts, a foot may also be represented by a single apostrophe (').

What is 6 and 7 12ths - 1 and 11 12ths?

(6 and 7/12) - (1 and 11/12)

= (79/12) - (23/12)

= 56/12

= 28/6

= 14/3

= 4 and 2/3

= 4.6666 in decimal

What is the sum of the angles of a pentagon?

For interior, the angle sum is 540 degrees, for exterior, the angle sum is 1260 degrees.

* * * * *

Partially correct!

The sum of the exterior angles of any polygon is 360 degrees. The exterior angle is the supplement of the interior angle (180 - interior), NOT the reflex angle (360- interior). So the sum given 1260, which is based on the reflex angles is incorrect.

Which of the ordered pairs is a solution of 2x plus 3y equals 13?

Dear Questioner its not able to solve two variables for one equation, give one more equation. Thanks

What is the difference from -27 to 0?

The difference from -27 to 0 is calculated by subtracting -27 from 0, which equals 27. This means that 0 is 27 units greater than -27 on the number line. In essence, the difference represents the distance between these two numbers, regardless of direction, resulting in a positive value of 27.
