A square has an area of 64x^2y^4. What is its side lenght and perimeter

Answers

For this case we have that by definition, the area of a square is given by: $A = l ^ 2$

Where:

l: It's the side of the square

We have as data that:

$A = 64x ^ 2 * y ^ 4$

So:

$64x ^ 2 * y ^ 4 = l ^ 2$

We cleared l, applying root to both sides:

$l = \pm \sqrt {64x ^ 2 * y ^ 4}$

We choose the positive value of the root:

$l = \sqrt {64x ^ 2 * y ^ 4}\nl = 8xy ^ 2$

So, the side of the square is: $8xy ^ 2$

The perimeter is given by:

$P = 4l\nP = 4 (8xy ^ 2)\nP = 32xy ^ 2$

Answer:

$l = 8xy ^ 2\nP = 32xy ^ 2$

Answer:

Side length = 8xy^2

Perimeter = 32xy^2.

Step-by-step explanation:

As it's a square the side length is the square root of the area

= √ (64x^2y^4)

= 8xy^2.

The perimeter is 4 times this.

The total number of legs , 1,500 , on four-legged and two-legged animals in a zoo can be represented by the equation 4x+2y=1,500. Interpret the x- and y- intercepts. Please show work so I can understand , if yu cant you can just give me the answers.

Answers

You need to clear the variables by moving everything else to the other side of the equal sign. So..

X
1) subtract 2y on each side => 4x = 1500 - 2y
2) divide by 4 => x = (1500-2y)/4

Y
1) subtract 4x on each side => 2y = 1500 - 4x
2) divide by 2 => y = (1500 - 4x)/2

Final answer:

The equation 4x + 2y = 1,500 refers to a zoo with two- and four-legged animals. The x-intercept at x = 375 represents the scenario with only four-legged animals, while y-intercept at y = 750 refers to the situation with only two-legged animals.

Explanation:

In the equation 4x + 2y = 1,500, 'x' stands for the number of four-legged animals and 'y' stands for the number of two-legged animals. The x-intercept is the value of 'x' when 'y' is zero, and the y-intercept is the value of 'y' when 'x' is zero. This can be calculated by setting the other variable to zero and solving for the remaining variable. For the x-intercept, when y=0, the equation becomes 4x = 1,500. Solving this gives x = 375. This implies that if there were no two-legged animals, there would be 375 four-legged animals. Similarly, for the y-intercept, when x=0, the equation becomes 2y = 1,500. Solving this gives y = 750, implying that if there were no four-legged animals, there would be 750 two-legged animals.

What times what equals 67

Answers

The number 67 times the number 1 is equal to 67.

The given number is 67.

Let x times the y equals to 67.

Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers.

Here, 67 is the prime number so, it is product of 67 and 1.

That is, 67×1=67

Therefore, the number 67 times the number 1 is equal to 67.

It's a prime number meaning only 1 and 67 are the only whole numbers that will give you 67

Compare and contrast area and volume

Answers

Both area and volume, in a vague way, can be seen as the measurement of the size of something. They are different because area is the size of a two-dimensional shape (like a square or a triangle), and volume is the size of a three-dimensional shape (like a cube or a pyramid).

Volume is where you find the volume of an object using Length*width*height.
Area is when you find the area using length*height
Volume is when you calculate 3D shapes
Area is when you calculate 2D Shapes
