Westside middle school sold 125 raffle tickets as a fundraiser.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Let, 'x' be the number of tickets sold.

Given, Each ticket costs $20 and the total revenue was $2500.

Therefore, The expression that represents this situation is,

20x = 2500.

x = 2500/20.

x = 125.

So, 125 tickets are sold.

Answer:

the answer is actually $943.40

To name segments skew to HI, we need a three-dimensional space and other lines or segments relative to HI. Skew segments do not intersect, are not parallel, and are not in the same plane as HI. Without additional context or a visual representation, we cannot list specific skew segments.

To answer the question: Name all segments skew to HI, we need to understand what skew lines are in geometry. Skew lines are lines that do not intersect and are not parallel, which means that they are not in the same plane. In three-dimensional spaces, if we have a line like segment HI, there could be many segments skew to it, but they must satisfy the conditions of being non-intersecting, non-parallel, and not co-planar with segment HI.

It's important to note that since skew lines must be in different planes, we cannot name specific segments skew to HI without additional context or a diagram showing the position of other lines or segments. If, for example, we have a cube structure, and HI is one edge of the cube, then any edge that is not on the same face or a parallel face could be considered skew to HI. However, without a visual or additional information, we cannot provide specific names of skew segments.

Therefore, to give a complete answer, we would require more information about the three-dimensional space or structure where segment HI is located.

Segments that are skew to HI do not lie in the same plane and do not intersect or parallel to the line HI.

A skew segment is a segment that does not lie in a single plane with another segment. To identify segments skew to HI, we need to find segments that do not lie in the same plane as segment HI.

Let's say segment HI is represented by the line passing through point H and point I. Any other segment that does not intersect this line and is not parallel to it would be a skew segment to HI.

For example, segments CD, EF, and GH can be considered skew to HI if they do not intersect the line HI and are not parallel to it.

Final answer:

Triangles A (right obtuse triangle) and B (equilateral scalene triangle) and D (right equilateral triangle) are impossible to draw because their defined characteristics contradict the specific angles and sides that a triangle must have to fit those definitions.

Triangle C (acute isosceles triangle) and E (right scalene triangle) are possible according to the definitions of their angles and sides.

Explanation:

When classifying triangles, the definition of each type of triangle must be considered to determine if it is possible to draw them based on their angles and sides. Here are the classifications:

A right triangle has one 90-degree angle.

An obtuse triangle has one angle greater than 90 degrees.

An acute triangle has all angles less than 90 degrees.

An equilateral triangle has three sides of equal length and three angles each measuring 60 degrees.

A scalene triangle has all sides of different lengths and, correspondingly, all angles are different.

An isosceles triangle has two sides of equal length and two angles that are equal.

Using these definitions:

A right obtuse triangle (A) is impossible because a triangle cannot have a right angle (90 degrees) and an obtuse angle (greater than 90 degrees) at the same time.

An equilateral scalene triangle (B) is impossible because an equilateral triangle has all sides equal, while a scalene triangle has all sides of different lengths.

An acute isosceles triangle (C) is possible as it can have two equal angles that are both acute, and the third angle also being acute.

A right equilateral triangle (D) is impossible because in an equilateral triangle all angles must be 60 degrees, which does not allow for a 90-degree angle.

A right scalene triangle (E) is possible because it can have one 90-degree angle and two other angles that are different from each other and both less than 90 degrees, with corresponding sides being of different lengths.

2x-3 = 2x-5

because both sides have the same x value ( 2x) this problem has no solution

The value of the expression is A = 2x - 3 = 2x - 5 and the equation has no solution

Given data ,

Let the expression be represented as A

Now , the value of A is

2x - 3 = 2x - 5

The like terms of the equation are the terms which does not contain any variables and only the whole numbers

So , the simplified value of A is

On combining the like terms in the expression , we get

Subtracting 2x on both sides , we get

On simplifying the equation , we get

-3 ≠ -5

Therefore , the value of A is has no solution

Hence , the equation is undefined and has no solution

Answer:

Option D. 2[L + ( L-8)] = 18

Step-by-step explanation:

Let the length of rectangle is L and width is W

The width of a rectangle is 8 meters shorter than its length

Then equation will be W = L - 8 -----------(1)

The perimeter of the rectangle is 18 cm

Then P = 18 cm = 2 ( l + w )

2(l + w) = 18 ----------(2)

Now we substitute the value of W from equation (1) to equation (2)

2[L + ( L-8)] = 18

Option D. is the answer.

the answer would be (B) -10  because 16 - 26 is -10

The integer that can be represented by 16 positive tiles and 26 negative tiles is -10.

One way to solve this problem is by considering the positive and negative tiles as positive and negative numbers, respectively. If we have 16 positive tiles and we subtract 26 negative tiles, we end up with a deficit of 10 negative tiles. Therefore, the integer that can be represented by these tiles is -10 (option B).

Length of boat on the scale in centimeter is 750 cm.

Here,

A scale drawing has scale 1 : 20.

Length of boat = 150 m

We have to find length of boat on the scale in centimeter.

What is value of meter in centimeter?

The value of one meter is 100 centimeter.

Now,

A scale drawing has scale 1 : 20.

Length of boat = 150 m

Hence, Length of boat on the scale = 150 ÷ 20 = 7.5 meter

So, Length of boat on the scale in cm = 7.5m =  7.5 x 100 cm = 750 cm

Therefore, Length of boat on the scale in centimeter is 750 cm.
