Answer:

in what order are the sides in?

Answer:

No

Step-by-step explanation:

According to the triangle rule, the sum of the lengths of any two sides of a triangle is greater than the length of the remaining side. Let's check this condition:

5 + 15 > 20 ? -> No

So such a triangle cannot exist. And the sides can't be that lengths.

The provided line's slope and y-intercept are therefore 2, 3. We can use the details provided by the slope-intercept form to graph a linear equation.

For instance, the equation y=2x+3 reveals that the line's slope is 2 and that its y-intercept is located at (0,3).

Finding the value of y at x=0 on a graph will reveal the y-intercept. The graph's intersection with the y-axis occurs at this location.

Y = mx + b, where m denotes the slope and b the y-intercept, is how the equation of the line is expressed in the slope-intercept form. We can see that the slope of the line in our equation, y = 6x + 2, is 6.

No, the sides of a triangle cannot have lengths 8, 16, and 18.

What is known as a triangle?

A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

This is because the length of any side of a triangle must be less than the sum of the other two sides and greater than the difference of the other two sides. This is called the triangle inequality theorem.

For a triangle with sides 8, 16, and 18, the side 8 is less than the sum of the other two sides 16+18=34, but greater than the difference of the other two sides 16-18=-2. Therefore, the sides of a triangle cannot have lengths 8, 16, and 18.

Answer:

1. The discount price of a T-shirt is  $14.40

2. The regular price of a hat is $22.50

3. The discount price is y = x(0.8)

Step-by-step explanation:

1.

20% = 0.2

18 times 0.2 = $3.60

18 - 3.60 = $14.40

So, the discount price of a T-shirt is $14.40

2.

100% - 20% = 80%

18 / 80 = 0.225

0.225 x 100 = $22.50

So, the regular price of a hat is $22.50

3.

Let's y represent the total cost

We have the equation

y = x(0.8)

The height of the triangular prism is 22 meters, having a total surface area of 1192 square meters.

An equation consists of numbers and variables linked together by mathematical operations to form an expression.

Let h represent the height of the triangular prism.

The base are right triangles with side lengths 12 meters, 15 meters, and 19 meters. Hence:

Total surface area = 2 * Area of base + sum of remaining area of surface

Total surface area = 2(1/2 * 15 * 12) + 12*h + 15*h + 19*h

The total surface area of the triangle prism is 1192 square meters. therefore:

1192 = 180 + 46h

46h = 1012

h = 22

The height is 22 meters

The 5th equivalent fraction to 1/5 is 5/25.

An equivalent fraction is a fraction that has the same value as another fraction, but a different numerator and denominator. There are an infinite number of equivalent fractions for any given fraction. To find the 5th equivalent fraction to 1/5, you can use the fact that equivalent fractions have a common multiple as a denominator.

The first step is to find a common multiple of the denominators of the fractions you want to compare. In this case, the denominator of the first fraction is 5, and you are looking for the 5th multiple of 5, which is 5*5 = 25.

The next step is to find the numerator that corresponds to the common denominator found in step 1. To do this, you can use the concept of cross-multiplication: the product of the original denominator and the new numerator is equal to the product of the original numerator and the new denominator.

1/5 * 5/5 = 1 * 5/5 * 5 = 5/25

Therefore, the 5th equivalent fraction to 1/5 is 5/25.

Proof by contradiction is a kind of proof that demonstrates the truth or the validity of a proposition by showing that assuming the proposition to be false leads to a contradiction.

More broadly, proof by contradiction is a form of argument that shows a statement by arriving at a contradiction, even when the initial assumption is not the disproof of the statement to be proved. In general, proof by contradiction is also known as indirect proof.

A mathematical proof utilising proof by contradiction usually proceeds as follows:

1. The proposition to be proved is P.

2. We consider P to be false, i.e., we assume ¬P.

3. It is then shown that ¬P implies falsehood. This is typically accomplished by deriving two mutually contradictory assertions, Q and ¬Q, and appealing to the Law of noncontradiction.

4. Since assuming P to be false leads to a contradiction, it is concluded that P is, in fact, true.

0.55 is the same as 55% since 55/100 is 0,55.

The probability that fewer than 58% of the residents in the sample enjoy riding roller coasters is b) 0.433.

What is probability ?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

The mean value is 0.62

Z value formula is

z = (x' -mean)/([tex]\sqrt{n}[/tex])

Substituting the given values, we get -

sigma = Sqrt {[tex](x'-mean)^2[/tex]/n}

Sigma = sqrt { [tex](0.58-0.62)^2[/tex]/75} = 0.09

z = (0.58-0.62)/(0.09)

z = -0.433

Hence , The probability that fewer than 58% of the residents in the sample enjoy riding roller coasters is b) 0.433.

The likelihood that less than 58% of the sample's residents enjoy going on roller coasters is 0.433.

Probability is the possibility that something will occur. The total number of conceivable outcomes.

The probability of an event is a number between 0 and 1, where, broadly speaking, 0 represents the event's impossibility and 1 implies certainty.

The average is 0.62.

The formula for the Z value is

Z = (x' – mean) ([tex]\sqrt{n}[/tex])

By substituting the provided values, we get -

Sigma Equals [tex]\sqrt{\frac{(x' - mean)^2}{n} }[/tex]

Sigma is equal to sqrt {[tex]{(0.58-062)^2/75[/tex]} = 0.09

z = (0.58-0.62)/(0.09) (0.09)

z = -0.433

Algebraic expressions involving radicals are known as radical expressions.  The root of an algebraic expression makes up the radical expressions (number, variables, or combination of both).

The main symbol attached to any algebraic expression is  x. Each radical expression consists of three separate components: first the "square root" sign itself serves as the radical sign.

The component of the expression inside the radical is known as the radicand

The degree outside the root indicates which root the radical refers to. Expressions without degree symbols have a degree of 2. A cube root is indicated by a degree of 3, a fourth root is shown by a degree of 4, and so on.

Answer:no

Step-by-step explanation:

Let's start with the first method: converting the fractions to the same denominator. First, we'll set up 5/8 and 1/2 side by side so they are easier to see:

Converting Denominator

5

8

&

1

2

Our denominators are 8 and 2. What we need to do is find the lowest common denominator of the two numbers. This is the smallest number that can be divided by both 8 and 2. In this case, the lowest common denominator is 8.

If we multiply the first denominator (8) by 1 we will get 8. If we multiply the second denominator (2) by 4 we will also get 8. We also need to multiply the numerators above the line by the same amounts so that the fraction values are correct:

5 x 1

8 x 1

1 x 4

2 x 4

This is what 5/8 and 1/2 look like with the same denominator:

5

8

&

4

8

Now that these fractions have been converted to have the same denominator, we can clearly see by looking at the numerators that 5 is NOT less than 4 which also means that 5/8 is NOT less than 1/2.

also we can extend term of x², x³, x⁴, x⁵ from x²¹ upto infinty because it didn't  change the value of x²¹ coefficient .

(1 - x¹¹)/(1 - x)[1/(1 - x)⁴]
