The largest 12- digit number where repeated digits are allowed?
If repeated digits are allowed, then the largest 12-digit number is 999,999,999,999 .
If repeated digits are not allowed, then the largest 12-digit number is 989,898,989,898 .
If the same digit can't be used more than once, then the largest possible number has only
10 digits. The number is 9,876,543,210 .
Oh, what a happy little question! Well, if we're looking for numbers that can go into 431, we can start by thinking about factors like 1, 7, 61, and 431 itself. Each of these numbers can be multiplied to fit perfectly into 431, just like adding different colors to create a beautiful painting. Remember, there's no mistakes here, just happy little numbers waiting to be discovered.
How do you write 3400000 in expanded form?
- 3,400,000 = (3 x 106) + (4 x 105) + (0 x 104) + (0 x 103) + (0 x 102) + (0 x 101) + (0 x 100) OR
- (3 x 1000000) + (4 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1)
Which shape has two pairs of parallel sides and no right angles?
The shape that fits this description is a parallelogram. A parallelogram has two pairs of parallel sides, meaning that opposite sides are parallel. Additionally, a parallelogram does not have any right angles, as the sum of its adjacent angles is always 180 degrees. Examples of parallelograms include rectangles, squares, rhombuses, and rectangles.
Where should you take lost salad Punchline Algebra?
Oh, dude, you should take that lost salad Punchline Algebra to the Salad Bar Association, obviously. They'll know how to solve that equation... or at least toss it in a bowl with some dressing. Like, it's a real mixed greens situation, you know?
Who discovered the systems of linear equation?
The concept of systems of linear equations dates back to ancient civilizations such as Babylonians and Egyptians. However, the systematic study and formalization of solving systems of linear equations is attributed to the ancient Greek mathematician Euclid, who introduced the method of substitution and elimination in his work "Elements." Later mathematicians such as Gauss and Cramer made significant contributions to the theory and methods of solving systems of linear equations.
Can revolution per minute convert to liters per minute?
Not in any sensible way. RPM is a measure of (angular) velocity whereas litres per minute is a rate of flow. Your hard disk will have an rpm but what does litres per miute mean in terms of the disk?
What is the exponent in 18 to the 4th power?
In the expression 18 to the 4th power, the exponent is 4. An exponent indicates the number of times the base number (in this case, 18) is multiplied by itself. So, 18 to the 4th power means 18 multiplied by itself 4 times, which is equal to 104,976.
3 times X= 3X
Because it is the same as 1X plus 1X plus 1X.
The X has an 'invisible' 1 in front of it....
Another example could be, What is 4 times X + 2?
It would equal 4X + 2, because when doing algebra you can only add things called 'like terms' so you can only add things like 2y+7y and 4yz+2yz or 4+3.
But you cannot add terms that are different, such as 2y+3z or 5+7x, they will just stay the same. So, 2y+3z=2y+3z and 5+7x=5+7x
However, you can MULTIPLY anything, so 2y times 3z= 6yz (2 times 3=6) and 5 times 7x= 35x and 4x times 3x= 12x2, this is because you have 2 xs!
So overall this is what you should know from all the above:
- You can multiply un-like terms! Even if the terms (eg. 2; 3x; 7y) are not the same.
- You cannot add or subtract un-like terms. You can only leave them as they are.
- When multiplying things like x or y or z remember to do your 'powers'
Examples:
- MULTIPLYING UN-LIKE TERMS-
3n times 2m= 6mn (put letters in alphabetic order) or 5y times 4x= 20xy
2. ADDING/SUBTRACTING LIKE AND UN-LIKE TERMS-
You can add/subtract 7z+3z/ 7z-3z, = 10z/4z.
3. DOING POWERS-
x times x3= x4 because there is an 'invisible' 1 next to the first x.
And 3x2 times 4x3 = 12x6
What does the word yields mean in math?
Oh, dude, "yields" in math just means "produces" or "results in." It's like when you mix peanut butter and jelly, and it yields a delicious sandwich. So, in math, if you add 2 + 2, it yields 4. Simple math, bro.
Solve for H.. A equals L x W x H?
To solve for H in the equation A = L x W x H, you need to isolate H on one side of the equation. To do this, divide both sides of the equation by (L x W) to solve for H. The formula for solving for H would be H = A / (L x W). This formula allows you to calculate the height (H) when given the area (A), length (L), and width (W) of a rectangular object.
What is the radius of a circle with an area of 452.16?
Divide 452.16 by pi and square root the answer which will give a radius of 11.99695787 or about 12 units of linear measurement.
What is 21.035 in expanded form?
21.035 = (2 x 10) + (1 x 1) + (0/10) + (3/100) + (5/1000) | twenty-one and thirty-five thousandths
Why are Cubes and Spheres called solid figures?
Well, honey, Cubes and Spheres are called solid figures because they have three dimensions: length, width, and height. Unlike those flat, two-dimensional shapes, these bad boys have depth, making them solid. So, next time you see a Cube or Sphere, just remember they ain't no flimsy paper cutouts - they're the real deal.
We also call them mixed fractions.
9.9 = 9 9/10 ( Nine and Nine-tenths) Nine is the integer and 9/10 is the fraction
We call it mixed number because you are "mixing" integers and fractions.
You can also write it as an IMPROPER fraction by doing this 99/10.
How do you draw a hexagon that has 2 right angles 2 acute and 2 obtuse?
If 1 or 2 of the obtuse angles are 'bent into' the hexagon then you can do it.
A hexagon has 720° sum of interior angles. If you have 2 right angles, then that's 180°, leaving 540° to be distributed over four angles. If the two acute angles are 89°, then that leaves 362° to be divided between two angles, so at least one of these two angles will need to be greater than 180°. Below is my text graphics attempt of one possibility (ignore the 'dot'). Note that both of the obtuse angles are greater than 180°:
|\_/|
|__.|

What 2 numbers multiplied together equal negative 5?
1*(-5)
5*(-1)
Those are the only two whole number equations that equal (-5). If you are looking for more than just whole numbers any two numbers you can multiply to equal positive 5, if you make one value negative your product will become negative.
(i.e. 2*2.5=5 | (-2)*2.5=(-5))
What is the value of 7 in 101700?
Oh, dude, you're hitting me with the big math questions, huh? So, like, in the number 101700, the value of 7 is like... 7. It's just hanging out there, being all cool and stuff, not causing any trouble.
What is the area of 16 squares if each square is 1 square units?
If each square has an area of 1 square unit, then the area of 16 squares would be calculated by multiplying the area of one square by the number of squares. In this case, the area of 16 squares would be 16 square units (1 square unit x 16 squares).
Oh, dude, the ratio of 32 to 1 is like, well, 32:1. It's just a fancy way of saying there are 32 of something for every 1 of something else. So, if you have 32 cookies and only 1 glass of milk, that's a 32:1 cookie-to-milk ratio. Easy peasy!
How many meters in 12.3 kilometers?
Well, honey, there are 12,300 meters in 12.3 kilometers. So, if you're trying to measure out a 12.3-kilometer run, you better lace up those sneakers and get ready to clock in some serious steps!
