None!!!! Because ;feet; is a measure of length, and 'square yards' is a measure of area.

However, if you mean 'How many SQUARE feet in 1440 square yards/' Then remember 3 feet = 1 yard ( linear)

3ft x 3 ft = 9 sq.ft. = 1 sq. yd (area)

So multiply 1440 sq.yds x 9 = 12960 sq.ft.

===== The answer .

The sum of 7 and x is represented by the expression 7 + x. In algebra, when we add a constant (like 7) to a variable (like x), we cannot simplify it further unless we know the specific value of x. Therefore, the sum of 7 and x is simply 7 + x.

The formula to calculate the area of a circle is A = πr^2, where A is the area and r is the radius. Given that the radius is 13, we can substitute this value into the formula: A = π(13)^2. Calculating this, we get A = 169π, which is approximately 530.93 square units.

Well, darling, a door is typically rectangular in shape. But hey, if you're feeling fancy, you can always opt for a round door like they have in hobbit holes. Just make sure it opens and closes, that's the important part.

It is 5and 3/5

Example: 30 and 42

Factor them.

2 x 3 x 5 = 30

2 x 3 x 7 = 42

Select the common factors.

2 x 3 = 6, the GCF

Combine the factors, eliminating duplicates.

2 x 3 x 5 x 7 = 210, the LCM

Check it.

30 x 42 = 1260

210 x 6 = 1260

It checks.

Oh, what a happy little question! In the number 468, the digit 4 holds a value of 400. It's like a little tree in a big forest, standing tall and proud. Just remember, each digit has its own special place and value, bringing harmony to the numbers they create.

In the context of chemistry, "4s" refers to the 4th energy level (shell) and the s orbital within that energy level. The "y" is not a standard scientific notation or symbol, so it is unclear what it represents in this context. If you provide more information or context, I can offer a more specific explanation.

The formula for volume of a cube is: Side ^ 3 (to the power of 3) so 6^3=216 so therefore that's the volume. 216 inches cubed

Oh, dude, it's like you're asking me to do math at a party. Okay, so "thrice a number" is just 3 times a number, and "five less than" means you subtract 5. So, the algebraic expression for "five less than thrice a number" would be 3x - 5. Easy peasy, right?

900 in scientific notation is written as 9 x 10^2. In scientific notation, a number is expressed as a coefficient multiplied by 10 raised to a certain power. In this case, the coefficient is 9, and the power of 10 is 2, indicating that you move the decimal point two places to the right to get the original number 900.

Let's figure it out.

10000 ten thousand

1000000 one million

How many more zeros does one million have than ten thousand?

One million has two more zeros than ten thousand so....

It must be 100.

Oh, dude, let's break this down. So, Amrit deposited 8000 bucks and then took out 2000 after a year, leaving 6000 in there. By the end of the third year, he got 7800 back. The rate of interest is 5% per annum. Easy peasy lemon squeezy!

To find the area of a rectangle, you simply multiply its length by its width. In this case, the length is 21m and the width is 17m. Therefore, the area of the rectangle would be 21m x 17m = 357 square meters.

Oh, dude, you're really hitting me with the tough math questions today, huh? Well, technically, 3 times 9 equals 27. But like, who really needs to know that stuff when you have a calculator on your phone, am I right? Math, schmath, am I right?

There aren't any whole numbers that satisfy these conditions. The only numbers that multiply to 23 are 23 and 1.

Speed is calculated by dividing distance by time, so:

100m / 20s = 5 m/s

The object is travelling at 5 metres per second.

Or, it is travelling at 7200 kilometers per second.

The decimal representation of pi is an irrational number, meaning it cannot be expressed exactly as a finite decimal or fraction. However, it is commonly approximated as 3.14159. Pi is defined as the ratio of a circle's circumference to its diameter and has infinite, non-repeating decimal digits. Mathematicians and scientists often use the symbol π to represent this fundamental mathematical constant.

Well, isn't that a lovely little equation we have here! To simplify 2x squared minus 2x, we can factor out the common factor, which is 2x. So, the expression simplifies to 2x(x - 1). Just like painting a happy little tree, it's all about finding the beauty in the simplicity of things.
