According to Euclidean geometry, a square has four equal sides and four equal angles, making it an equilateral quadrilateral. Another name for it is a rectangle with two adjacent sides that are the same length. An equilateral quadrilateral is one that has four equal sides and four equal angles, like a square. Angles that are 90 degrees or straight are square angles. The square's diagonals are also split at a 90-degree angle and are evenly spaced. a rectangle with two equal sides that is adjacent. a quadrilateral with four equal sides and straight angles on all four sides. a parallelogram with two adjacent sides that are equal and create a right angle. rhombus with straight sides.

given

the square can be completed by adding the square of half the x-coefficient: (-12/2)² = (-6)² = 36.

Therefore , the solution of the given problem of inequality comes out to be m > 4.24.

In mathematics, an inequality is a relationship of linear solution or integers without the equal sign. Inequity inevitably leads to imbalance. When two numbers are not equal, there is an inequality between them. Between equality and inequality, there are differences. In instances when the variables aren't similar or equal, I've used the most common symbol (). There are many inequalities that may be utilised to compare values regardless of how small or huge they are.

Here,

There are 2 semi circles.

One that is on left side ( say S1)and the other one at the bottom(say S2) of the figure. Both these semi circles have diameter 30.

perimeter of S1 = (2*pi*15)/2

perimeter of S2 = (2*pi*15)/2

There is another figure which is of a semicricle(say S3). The radius is 30.

Perimeter of S3 = (2*pi*30)/4

Required perimeter

= S2+ S3-S1

= [(15*pi)/2] + [(15*pi)]- [(15*pi)/2]

Answer: The expression is (22) +12/(22) = 4 + 12/4 = 4 + 3 = 7.

Step-by-step explanation:

To evaluate the expression 2w+12 ÷ (2x) for w=2 and x=2, we need to substitute the given values into the expression and simplify.

First, we substitute the value of w=2 into the expression, giving us 2(2)+12 ÷ (2x).

Next, we simplify the expression by multiplying 2 and 2, getting 4+12 ÷ (2x).

Then we add 4 and 12, getting 16 ÷ (2x).

Finally, we substitute the value of x=2 into the expression, giving us 16 ÷ (2(2)) = 16 ÷ 4 = 4.

So the final value of the expression 2w+12 ÷ (2x) for w=2 and x=2 is 4.

Step-by-step explanation:

The expression that illustrate the diagram below is f(x) = 47-2x

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power. In other words, none of the exponents can be greater than 1.

In the diagram, the total no of box is 45 and 2 boxes are missing on the second box. Therefore the constant in the the expression is 45+2 = 47. Let x be the variable.

Therefore f(x) = 47-2x

when it is pattern 1

x= 1

f(1) = 47-2 = 45

when it's pattern 2

f(x) = 47-2×2 = 43

when it's pattern 3

f(x) = 47- 2×3 = 41

therefore the expression that can illustrate the diagrams is f(x) = 47-2x

The shape of the front of the Mexican tote bag can be described as a trapezoid. A trapezoid is a quadrilateral with one pair of parallel sides and the other pair of non-parallel sides.

In this case, the sides of the trapezoid are perpendicular two pairs, meaning that one pair of non-parallel sides is perpendicular to the other pair of non-parallel sides.

The front of the Mexican tote bag typically has a wider top and a narrower bottom, which creates the parallel sides of the trapezoid. The wider top provides a larger opening for easy access to the contents of the bag, while the narrower bottom helps maintain the bag's shape and stability.

This trapezoidal shape is commonly seen in tote bags as it offers practicality and functionality. The wider top allows for convenient storage and retrieval of items, while the narrower bottom helps distribute the weight evenly and prevents the bag from sagging.

The trapezoidal shape of the front of the Mexican tote bag combines both style and functionality. It not only provides an aesthetically pleasing design but also offers practicality in terms of storage capacity and easy access to the bag's contents.

Answer:

  1630

Step-by-step explanation:

You want to know what Martin paid to cover 1650 in doctor bills when his insurance pays 80% after a deductible of 500 has been met.

When insurance pays 80% of the amount over 500, Martin pays the other 20%. Martin's share of the bill is ...

  500 + 0.20(6150 -500)

  = 500 +0.20(6150) -0.20(500) = 400 +0.20(6150)

  = 400 +1230 = 1630

Martin paid 1630 in all, including the deductible.

Answer: So the cost of each cup is $4.00.

We know that the cost of 5 cups of coffee is under $20.00. To find out the cost of each cup we need to divide the total amount by the number of cups.

$20.00 / 5 = $4.00

So the cost of each cup is $4.00.

(x - 4)2 + y2 = 36 and (x + 6)2 + y2 = 144 are the equations represent circles that have a diameter of 12 units and a center that lies on the y-axis

In geometry, the diameter of a circle is the straight line passing through the center of the circle and connecting two points on the circumference.

Also, a diameter is a straight line that passes through the center of a circle or other curved object and has its endpoints on the circumference. It is the longest line that can be drawn in a circle and is equal to twice the radius.

Consequently, the equations that represent circles that have a diameter of 12 units and a center that lies on the y-axis are (x - 4)2 + y2 = 36 and (x + 6)2 + y2 = 144

The k value of the given problem is 8. The solution is obtained using the concept of algebra.

A branch of mathematics known as algebra deals with symbols and the fine operations performed on them. Variables are the name given to these symbols because they warrant set values.

Algebra aids in the result of fine problems and enables the derivate of unknown figures, similar as interest rates, rates, and probabilities. In order to remake the equations, we can express the associated unknown amounts using variables from algebra.

We are given equation: y=8x.

General form of an equation is y=kx where k is the constant of variation.

Also, y varies directly with both i.e. k and x.

So, from the above explanation, we find that k=8.

What is similar polygons?

Two polygons with the same shape but different sizes are said to be similar polygons. Comparable polygons have corresponding sides that are proportional and corresponding angles that are congruent.

If the corresponding sides have a constant ratio and the corresponding angles are congruent, two polygons are said to be similar.

Let the pentagons ABCDE and JKLMN are similar.

Means their shape is same but differ in size.

Each side of pentagon JKLMN is 0.8 units greater than the pentagon ABCDE.

The measure of CD is 2 units.

⇒ The measure of LM = 2 + 0.8 = 2.8

Therefore , the solution of the given problem of rectangle comes out to be area =  8x⁵ + 28x⁴ -30x² +18x.

In Euclidean plane geometry, a rectangle is a square with four right angles. You may also refer to it as a quadrilateral that seems to be equiangular, meaning that each of its angles is equal. Another possibility for the parallelogram is a straight angle. Four of the sides of a square are of identical length. Four 90 ° vertices and equal equal sides make up a rectangle-shaped quadrilateral.

Here,

Given :

Length of rectangle = 4x³ + 2x² -6x +3

and

Width =  2x² + 6x.

Thus ,

Area of rectangle = length * width

=>  (4x³ + 2x² -6x +3) * (2x² + 6x)

A number or ratio that is expressed as a fraction of 100 is known as a percentage in mathematics. There are also sporadic uses of the acronyms "pct.," "pct," and "pc." However, the percent sign "%" is widely used to signify it. There are no dimensions to the percentage amount. Percentages are essentially fractions because they have a numerator of 100. Put the percent sign (%) next to a number to indicate that it is a percentage. For instance, you would score a 75% if you answered 75 out of 100 questions on a test correctly (75/100). Divide the money by the total to get percentages, then multiply the result by 100. The formula (value/total) x 100% is used to determine the percentage.
