How do you write 15.89 in expanded form?
To write 15.89 in expanded form, you would break down each digit's place value. In this case, 15.89 can be written as (10 + 5) + (0.8 + 0.09). This breaks down the number into its individual place values, showing that 15.89 is composed of 10 + 5 for the tens and ones places, and 0.8 + 0.09 for the tenths and hundredths places.
How many times does 12 go into 1944?
To calculate how many times 12 goes into 1944, you would divide 1944 by 12. The result is 162, which means that 12 goes into 1944 exactly 162 times. This is because 12 multiplied by 162 equals 1944.
What is the volume in liters occupied by 1.21g of Freon-12 gas at 0.980 ATM and 308k?
To calculate the volume of a gas using the ideal gas law, we use the formula V = (nRT)/P, where V is the volume, n is the number of moles of gas, R is the ideal gas constant, T is the temperature in Kelvin, and P is the pressure. First, we need to convert the mass of Freon-12 to moles using its molar mass. Then, we can plug in the values for n (moles), R (0.0821 L·atm/mol·K), T (308 K), and P (0.980 atm) to find the volume in liters.
What is the history of the quadratic formula?
The Babylonians, as early as 1800 BC (displayed on Old Babylonian clay tablets) had an early version.
In the Sulba Sutras in ancient India circa 8th century BC quadratic equations of the form ax2 = c and ax2 + bx = c were explored using geometric methods. Babylonian mathematicians from circa 400 BC and Chinese mathematicians from circa 200 BC used the method of completing the square to solve quadratic equations with positive roots, but did not have a general formula. Euclid, the Greek mathematician, produced a more abstract geometrical method around 300 BC. In 628 CE, Brahmagupta, an Indian mathematician, gave the first explicit (although still not completely general) solution of the quadratic equation: " To the absolute number multiplied by four times the [coefficient of the] square, add the square of the [coefficient of the] middle term; the square root of the same, less the [coefficient of the] middle term, being divided by twice the [coefficient of the] square is the value. (Brahmasphutasiddhanta (Colebrook translation, 1817, page 346)[2] " The Bakhshali Manuscript dated to have been written in India in the 7th century CE contained an algebraic formula for solving quadratic equations, as well as quadratic indeterminate equations (originally of type ax/c = y). Mohammad bin Musa Al-kwarismi (Persia, 9th century) developed a set of formulas that worked for positive solutions based on Brahmagupta.[3] The Catalan Jewish mathematician Abraham bar Hiyya Ha-Nasi authored the first book to include the full solution to the general quadratic equation.[4] The writing of the Chinese mathematician Yang Hui (1238-1298 AD) represents the first in which quadratic equations with negative coefficients of 'x' appear, although he attributes this to the earlier Liu Yi. The first appearance of the general solution in the modern mathematical literature is evidently in an 1896 paper by Henry Heaton.[5] # ^ Stillwell, p. 86. # ^ a bStillwell, p. 87. # ^ BBC - h2g2 - The History Behind The Quadratic Formula # ^ The Equation that Couldn't be Solved # ^ Heaton, H. (1896) A Method of Solving Quadratic Equations, American Mathematical Monthly 3(10), 236-237.
Well, isn't that just a happy little math problem we have here! To factor 2x-12, we can first look for the greatest common factor, which in this case is 2. So we can factor out the 2 to get 2(x - 6). And there you have it, a beautifully factored expression ready to bring joy to your mathematical world.
Who invented the multiplication table?
Multiplication table has its origin from simple mathematical table.Mathematical tables can be traced backed to 1900 BC in the Babylonian mathematics in the clay tablets found one of the most important tablet is named as Plimpton322.Then the Greek Astronomer Hipparchus used Trignometric Tables those can be the multiplication table in some sense.Those may be the Greeks who developed multiplication tables on road around 200BC.

The history of mathematics dates back thousands of years to ancient civilizations such as the Babylonians, Egyptians, and Greeks. These early mathematicians made significant contributions to the development of arithmetic, geometry, and algebra. The study of mathematics continued to evolve through the Middle Ages and Renaissance, with advancements in calculus, number theory, and probability theory. Today, mathematics plays a crucial role in various fields such as science, engineering, economics, and technology.
What is the number that has 999 zeros?
The number that has 999 zeros is known as a googol, which is written as 10^999 in scientific notation. A googol is a large number used in mathematics and was popularized by mathematician Edward Kasner in the early 20th century. It is often used to illustrate the concept of extremely large numbers and is much larger than a trillion or even a trillion trillion.
Who invented the triangular prism?
The triangular prism is a geometric shape that has been known since ancient times, so it is difficult to attribute its invention to a single individual. However, the concept of a prism with a triangular base can be traced back to ancient Greek mathematicians such as Euclid. Euclid's Elements, written around 300 BC, contains detailed explanations of various geometric shapes, including the triangular prism.
How can 8 leave 3 if you take half away?

What word in math start with j?
In mathematics, one term that starts with the letter "J" is "joint variation." Joint variation refers to a situation where a variable depends on two or more other variables in a combined way. It is often used in algebra and calculus to describe relationships between multiple quantities.
You sell 12 eggs at the price for which you buy 20 eggs What is your profit percent?
Let 20 eggs cost $ 5.00, then 1 egg costs 5/20 = 1/4 = $ 0.25.
So that 12 eggs cost 12 x 0.25 = $ 3.00.
Since 12 eggs are sold for $ 5.00, then the profit is 5 - 3 = $ 2.00.
($ 2.00 is what percent of $ 5.00?)
Thus, the profit percent is $ 2.00/$ 5.00 = 0.4 = 40%
What is a casual relationship in math?
Oh, dude, a casual relationship in math is like when two variables hang out and do their thing without any serious commitment. It's like, they're just chillin' together, you know? They're not locked down in some complex equation, they're just keeping it low-key and seeing where it goes.
To calculate .88 divided by 84.48, you would simply divide the two numbers. This would result in approximately 0.0104. This is the quotient when dividing .88 by 84.48.
How many times does 18 go into 99?
Well, darling, 18 goes into 99 a total of 5 times. But let's not forget about that pesky little remainder of 9 hanging out at the end, just causing a ruckus. So, technically, 18 goes into 99 exactly 5 times with a remainder of 9. Hope that clears things up for you!
What are the features of an abacus?
An abacus consists of a rectangular frame divided into two by a horizontal bar. It has a number of vertical wires running across both sections with two "beads" in the upper section and five in the lower..
What is 30 minutes after 1248 pm?
To find 30 minutes after 12:48 pm, you would add 30 minutes to 12:48 pm. This would result in 1:18 pm. This can be calculated by converting 12 hours and 48 minutes to just minutes (12 x 60 + 48 = 768 minutes), adding 30 minutes (768 + 30 = 798 minutes), and then converting back to hours and minutes (798 ÷ 60 = 13 hours with a remainder of 18 minutes).
What does repeated subtraction mean in math?
Repeated subtraction in math refers to the process of subtracting the same number multiple times from a given quantity. It is often used to find the result of division or to break down a larger number into smaller equal parts. For example, if you have 12 apples and you subtract 3 apples repeatedly, you are performing repeated subtraction.
