Square may be defined a closed figure having four equal sides.
Within mathematics there are many figures. One of the closed figures is Square. Square is formed when four sides of equal length are enclosed to from a closed figure. It is a two dimensional figure. A square has four vertices as well as four internal angles. All the internal angles of the square are equal and have a value equal to 90°. The opposite sides of a square are equal as well as parallel to each other. The diagonals of the square are equal in length and all the diagonals of square intersect each other at an angle equal to 90°. if a square has length of its side equal to 'a', then the area of the square will be equal to a². The perimeter of the square will be equal to 4a.

By using some exponent properties, we will see that the equivalent expression to √(x⁵*y⁶) is:
x²*y³*√x
So the correct option is the first one.
How to simplify the given expression?
Here we need to remember 3 properties about exponents that we will need to use.
These are:
√x = x¹´²
Also remember that:
(xⁿ)ᵃ = xⁿ*ᵃ
And that:
√(a*b) = √a*√b
Well, our expression is:
√(x⁵*y⁶)
We can rewrite this as:
√x⁵*√y⁶
And using the first and second properties we can rewrite.
√x⁵ = x⁵´² = x⁴´²*x¹´² = x²*√x
√y⁶ = y⁶´² = y³
Replacing all that we get:
√(x⁵*y⁶) = x²*y³*√x

What is confidence interval?
A confidence interval (CI) for an unknown parameter in frequentist statistics is a range of estimations. The most popular confidence level is 95%, but other levels, such 90% or 99%, are occasionally used for computing confidence intervals. The fraction of related CIs over the long run that actually contain the parameter's true value is what is meant by the confidence level. The degree of confidence, sample size, and sample variability are all factors that might affect the width of the CI. A larger sample would result in a narrower confidence interval if all other factors remained constant. A wider confidence interval would also be required by a higher confidence level and would be produced by a sample with more variability.

  Is it true that 7w + 4 = 5w + 12.
A. Write three more equations that you know are true based on this information.
B. Find the value of 2w.
C. Find the value of w.
Answer:
A. Here are three more equations that are true based on the information you provided:
1. 3w + 2 = 2w + 6
2. 5w - 6 = 4w - 8
3. 7w - 5 = 6w - 7
B. To find the value of 2w, we need to first solve for w in the original equation 7w + 4 = 5w + 12. We can do this by subtracting 5w from both sides of the equation, which gives us 2w + 4 = 12. Then we can subtract 4 from both sides to get 2w = 8. Therefore, the value of 2w is 8.
C. To find the value of w, we can divide both sides of the equation 2w = 8 by 2, which gives us w = 4. Therefore, the value of w is 4.

The percent error of Ira’s guess for the number of buttons is 25%
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, Ira’s guess is 200 buttons but the actual number of buttons is 250.
The net amount error is (250 - 50) = 50 buttons.
Now to obtain percentage change we'll divide the net amount change by the original amount and multiply it by 100% which is,

What is the equation of the line passing through point 1 2?
The equation of the line will be equal to y = -x + 3.
The equation of the line in slope intercept form is expressed as
y = mx + c
where m is the slope of the line, c is the y-intercept and x and y are independent and dependent variables respectively.
We have the equation of the line as y = x + 5 and we need to find equation of line perpendicular to this line. The slope of the line is 1.
If two lines are perpendicular then the relation in their slope is expressed as
m₁ × m₂ = -1 and we have m₁ = 1 and m₂ = m so we get
1 × m = -1
=> m = -1
Now, the equation of the line will be
y = (-1)x + c
Also, the line passes through (1, 2) so on putting these values
2 = -1 + c

Given, each of 20 people generated a random sample of whole numbers and constructed a 95% confidence interval for the proportion that are odd.
we have to find the confidence interval under confidence of 95%.
Subtract 1 from your sample size. 25 – 1 = 24. This gives you degrees of freedom.
Subtract the confidence level from 1, then divide by two.
(1 – 0.95) / 2 = 0.05
For 24 degrees of freedom (df) and α = 0.05, the result is 1.645.
Divide your sample standard deviation by the square root of your sample size.
0.1 / √(20) = 0.02
Now, 0.02 × 1.645 = 0.0329
The lower end of the range

Bella's Pizza Shop charges $4.50 for a small pizza, $7.00 for a medium pizza,and $9.00 for a large pizza. Additional toppings cost extra depending on the size of the pizza ordered. Bruce ordered a large pizza with three toppings that cost a total of $12.60.
Answer:
1.20
Step-by-step explanation:
To determine how much Bruce's large pizza with three toppings would cost without the additional toppings, you would need to know the base price of a large pizza at Bella's Pizza Shop. Based on the information you provided, a large pizza at Bella's Pizza Shop costs $9.00. To determine the cost of the additional toppings, you would need to know the cost of each topping and the number of toppings ordered. Since this information is not provided, it is not possible to determine the cost of the additional toppings or the total cost of Bruce's order.
The large pizza costs $9.00 without any toppings.
The additional toppings cost $12.60 - $9.00 = $<<12.60-9.00=3.60>>3.60.
Therefore, each topping costs $3.60 / 3 = $<<3.60/3=1.20>>1.20. Answer: {1.20}.
Answer:
$1.20
Step-by-step explanation:
Assuming the question is "how much does each topping cost", you could solve it like this:
Total - large pizza price.
12.6 - 9 = 3.6.
Since Bruce got 3 toppings you'll want to do 3.6/3 which will give you 1.2.
If you add it all back up it should give you 12.60 again.
1.2(3)+9=12.6

The system of inequalities are 5x−4y≥9 and 6x+8y≤10.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The intersection consists of the elements that are contained in all of the intervals.
Here, 5x−4y≥9 -------(I) and 6x+8y≤10 -------(I)
Now, y ≤ 5/4 x+(-9/4); y ≤ -3/4 x+5/4
⇒ 5/4 x+(-9/4) ≤ -3/4 x+5/4
⇒ 5/4 x+3/4 x ≤ 5/4+9/4
