How do you write four less than a number is two thirds of that number?

Alright, buckle up buttercup. To write "four less than a number is two-thirds of that number," you can use the equation x - 4 = (2/3)x. Here, x represents the number you're talking about. Now go forth and solve that bad boy, and remember, math is your friend, not your enemy.

How do you right 256 in expanded form?

256 = (2 x 102) + (5 x 101) + (6 x 100) OR (2 x 100) + (5 x 10) + (6 x 1).

What is the area of a triangle with base 2cm and height 5cm?

To find the area of a triangle, you use the formula: Area = 1/2 * base * height. In this case, the base is 2cm and the height is 5cm. Plugging these values into the formula, we get: Area = 1/2 * 2cm * 5cm = 5 square centimeters. Therefore, the area of the triangle is 5 square centimeters.

What is the volume of a cube if the surface area is 9600 sq ft?

Oh, what a happy little question! To find the volume of a cube, we need to know the length of one side. Since the surface area is 9600 sq ft, we can find the length of one side by taking the square root of 9600, which is 96. So, the volume of the cube would be 96 x 96 x 96 = 884,736 cubic feet. Just imagine all the lovely things you could create in a space that big!

What is the volume of a cube with 25 cm sides?

The volume of a cube is calculated by cubing the length of one of its sides. In this case, the cube has sides of 25 cm, so the volume would be 25 cm x 25 cm x 25 cm, which equals 15,625 cubic centimeters.

Why is retardation called negative acceleration?

Oh, dude, so like, when something is slowing down, it's actually experiencing negative acceleration. It's like the opposite of when you speed up, you know? So, they call it retardation because it's like saying, "Hey, slow down, negative acceleration coming through!" It's just a fancy way of saying things are getting slower, man.

How many angle measures an acute angle?

An ACUTE angle is any angle between, but NOT including, 0 to 90 degrees.

0 degrres ; no angle

90 degrees ; right angle.

Angles between 90 and 180 degrees are OBTUSE

Angles between 180 and 360 degrees are REFLEX.

What is the answer of a square - 5a equals 0?

"The answer" is the number that 'a' must be in order to make the statement true.

There are two answers.

a = zero

and

a = 5

Which integer between 2 and 200000000000000 is a perfect square a perfect cube and a perfect fifth power?

If a number is a perfect square, then its prime factors can be split into two identical groups: if a perfect cube, three groups; if a perfect fifth power, five groups. The best way to attain this sort of 'symmetry' is to only use one prime factor. Since we are looking for small (ish) solutions, we'll use 2. It only remains to decide how many 2's to multiply together. The number needs to be divisible by 2, 3 and 5. We are looking for the lowest common denominator of 2, 3 and 5, which is 30. 22x3x5 = 230 = 1073741824 = (22x3)5 = (22x5)3 = (23x5)2 The next smallest solution is given by 330 = 205891132094649, which is just a little bit bigger than 2 x 1014. So the question is correct in assuming that only one answer exists.

Is length times width the same as base times height?

No, length times width is not the same as base times height. In geometry, length times width typically refers to the area of a two-dimensional shape, such as a rectangle. On the other hand, base times height is commonly used to find the area of a triangle or a parallelogram. The formulas for calculating area differ depending on the shape being measured.

What is the distance between points (-8-3) and (45)?

Apply Pythagoras

h^(2) = x^(2) + y(2)

Hence for points ( -8,-3 ) & ( 4,5)

h^(2) = (-8-4)^(2) + ( -3-5)^(2).

h^(2) = (-12)^(2) + (-8)^(2)

h^(2) = 144 + 64

h^(2) = 208

h = sqrt(208)

h = 14.222051.... (The distance between the two points.

What is the two consecutive whole numbers between 190?

There is no such thing. To specify that some number is "between" somthing, you must specify two different numbers, not just one.

What is the square root of 4x?

We use the property of square roots that says the square root of (ab)=square root (a) multiplied by square root of b So square root (4x)=square root (4) mutiplies by square root of x =2(square root (x)) 2sqrt(x)

What two numbers add to nine and multiply to 144?

Well, isn't that just a happy little math problem! The two numbers you're looking for are 12 and 12. They add up to 24 and when you multiply them together, you get 144. Just like painting a beautiful landscape, sometimes all it takes is a bit of patience and a gentle touch to find the right answer.

How can you find a perimeter in a square that sides measures 35 mm?

Well, isn't that just a happy little question! To find the perimeter of a square, you simply add up all the sides. Since all sides of a square are equal, you can multiply the length of one side by 4. In this case, with each side measuring 35 mm, the perimeter would be 35 mm + 35 mm + 35 mm + 35 mm = 140 mm. Just like that, you've found the perimeter of your square!

What is the perimeter of 35 acres?

An area can have any shape; it can have any area greater than or equal to the minimum perimeter which is given by a circle.

Thus the perimeter is any perimeter you like greater than or equal to approx 1459 yds (a circle of radius approx 232.21 yds).

What is 3x divided by x?

Well, isn't that a happy little math problem! When you have 3 times a number and you divide that by the same number, you're left with just 3. It's like painting a beautiful landscape with just three simple colors - simple and harmonious.

What is 1391000 in scientific notation?

1391000 in scientific notation is 1.391 x 10^6. This is because you move the decimal point to the left until there is only one non-zero digit to the left of the decimal point, and then multiply by 10 raised to the number of places you moved the decimal point. In this case, you move the decimal point six places to the left, resulting in 1.391 x 10^6.

What is 4.35 in lowest term fraction or mixed number?

Well, honey, 4.35 as a fraction in its lowest terms is 435/100. Simplify that bad boy down and you get 87/20. And if you wanna jazz it up with a mixed number, it's 4 7/20. Hope that clears things up for ya!

What is y divided by y squared?

Well, darling, when you divide y by y squared, you're basically dividing y by y multiplied by y. So, the answer is 1 over y. Simple math, really. But hey, at least you're not dividing by zero and causing a mathematical apocalypse.
