Mr. Cho received 3840 eggs in the beginning.

Let's assume that Mr. Cho received x eggs in the beginning.

In the morning, he sold 1/3 of the eggs, so he had 2/3 of the eggs left. Therefore, he had 2/3 x eggs left after the morning sales.

In the afternoon, he sold 320 eggs, so he had 2/3 × x - 320 eggs left at the end of the afternoon.

At the end of the day, he found that 1/4 of the eggs were not sold, which means that he had 3/4 of the eggs left. Therefore, we have:

3/4 × x = 2/3 × x - 320

Multiplying both sides by 12, we get:

9x = 8x - 3840

Simplifying, we get:

x = 3840

Therefore, Mr. Cho received 3840 eggs in the beginning.

Answer:

To solve the equation:

2/3x - 1/5x = x - 1

First, we need to find a common denominator for 2/3 and 1/5, which is 15. So we can rewrite the equation as:

(10/15)x - (3/15)x = 15/15 x - 1

Simplifying the left side:

(7/15)x = 15/15 x - 1

Multiplying both sides by 15:

7x = 15x - 15

Subtracting 7x from both sides:

-8x = -15

Dividing both sides by -8:

x = 15/8 or 1.875

Therefore, the solution to the equation is x = 1.875.

a) The number of tiles she will need is 736 tiles

b) The amount it would cost to tile the entire bathroom floor is £3312

From the question, we are to determine the number of tiles Mrs. Maryam will need to tile her entire bathroom floor

To determine the number of tiles that would be needed, we will determine the area of the bathroom floor

Area of the bathroom floor = (13 × 16) - (3 × 4) - (4 × 3)

Area of the bathroom floor = 208 - 12 - 12 m²

Area of the bathroom floor = 184m²

From the given information. the square tile she wants to buy is 50 cm long. That is, 0.5 m long

The area of one tile will be

Area of a tile = 0.5 × 0.5

Area of tile = 0.25 m²

Thus,

The number of tile she will need = 184m² / 0.25 m²

The number of tile she will need = 736 tiles

b) If each tile costs £4.50, we are to determine how much it would cost to tile her entire bathroom

The amount it would cost to tile the entire bathroom = 736 × £4.50

The amount it would cost to tile the entire bathroom  = £3312

Hence, the amount it would cost is £3312

Three reasons why the other method is not better is because to use drawing program would mean you would need some sort of technology and electricity to use it and some places, like third world countries, do not have access to that, so most probably you would have to resort to paper. Also, drawing programs are based off the skills needed to create geometric figures with a straightedge and compass. And lastly, what if we had no more technology anymore? Then how would we use a drawing program? Drawing programs are only reliable when electricity is located.

SO THE ANSWER IS A hope it help :)

I believe that there is a need for students to understand and be able to construct geometric figures using a compass and straightedge.

The compass and straightedge can be used anywhere. The compass and straight edge have been around for lots of years. They are a valuable tool for students in math and in real world applications. The compass and straightedge are portable and handy to use any given time. That is why there is a need for students to understand and be able to construct geometric figures using a compass and straight edge.

The compass and straight edge have been used to accurately create geometric figures for thousands of years. This shows that they are accurate and useful to us. Using technology is less reliable for many reasons. Technology can break, or glitch and shut down, making you lose all your work. You cannot draw on physical objects with an iPad like you could with a pencil or pen. Having a physical copy of things makes things easier to keep track of. Having a blueprint would be better than having a drawing on your phone. You can get another blueprint, but if your phone breaks and that drawing isn't saved, it's gone.

These are only a few reasons why I believe that there is a need for students to understand and be able to construct geometric figures using a compass and straightedge.

A triangle is a polygon since it has three sides and three vertices. It is one of the basic geometric shapes. The name given to a triangle containing the vertices A, B, and C is Triangle ABC. A unique plane and triangle in Euclidean geometry are discovered when the three points are not collinear. Three sides and three corners define a triangle as a polygon. The triangle's corners are defined as the locations where the three sides converge. 180 degrees is the result of multiplying three triangle angles.

Carrie has 4 more pints of paint than Bryan.

Carrie has 3 gallons of paint, which is equivalent to 12 quarts (1 gallon = 4 quarts). On the other hand, Bryan has 10 quarts of paint.

To compare the quantities in the same unit, we note that 1 quart is equal to 2 pints.

Carrie's 12 quarts of paint is equivalent to 12 × 2 = 24 pints.

Bryan's 10 quarts is equivalent to 10 × 2 = 20 pints.

To find the difference, we subtract Bryan's pint quantity from Carrie's:

24 - 20 = 4 pints.

Therefore, Carrie has 4 more pints of paint than Bryan.

Lamont wants to buy raspberries and apples to make a fruit tart raspberries cost $3.50 per pound and apples cost $3.75 per pound. How much dose he spend if he buys 3 pounds raspberry and 2 pounds of apples ?how much does he spend if he buys X pounds of raspberries and Y pounds of apples ? ​

Answer:

$18.00 ;

3.50x + 3.75y

Step-by-step explanation:

Given that:

Cost per pound of raspberry = $3.50

Cost per pound of apple = $3.75

Cost of 2 pounds of raspberry = 3 * $3.50 = $10.50

Cost of 2 pounds of apple = 2 * $3.75 = $7.50

Total spent = $(10.50 + 7.50) = $18.00

Cost of X pounds of raspberry and Y pound of apple

.

(3.50 * X) + (3.75 * Y)

3.50x + 3.75y

Considering the given image, we can easily spot that (B) line 2 is the line of symmetry.

A form or item is divided into two equal and symmetrical portions by a line of symmetry.

Because it divides the figure symmetrically and the separated portions resemble mirror images of one another, we also refer to this line as the axis of symmetry or the mirror line.

Rotational symmetry, reflection symmetry, translation symmetry, and glide reflection symmetry are some examples of symmetries.

Planar symmetry, which refers to various types of symmetry on a flat surface, is illustrated by these four different types of symmetry.

So, according to the given image:

LIne 1 and 3 are not making the 2 identical halves of the figure.

Line 2 is making the exact identical half of the figure.

Answer:

Step-by-step explanation:

x + y = 1           -------------------(I)

5x + 3y = -3 -----------------(II)

Multiply (I) by (-5)    -5x - 5y = -5

                               5x + 3y = -3          {Now add}

                                     -2y = -8  

                                        y = -8/-2
