Answer:

8 in each bag 32 total hoped this helped :)

Step-by-step explanation:

The classroom has 50 girls. The solution was achieved by adding the ratio values (3+5) to get the total parts, dividing the total students by this value to find the value of each part, and then multiplying this by the number of parts for girls.

The subject of this question is a problem in Mathematics that deals with ratios and proportions. Specifically, the ratio of boys to girls in a classroom of students. The ratio given is 3:5, which means for every 3 boys, there are 5 girls. In a classroom with 80 students, we first need to calculate the total parts of this ratio by adding 3 (boys) and 5 (girls), which gives us a total of 8 parts. Having done that, we can now determine the value of a single part by dividing the total number of students (80) by the total parts (8). This gives us 10 students per part. To find out the number of girls, we multiply the number of parts for girls (5) by the number of students per part we computed (10), which equals 50. Therefore, in this classroom, there are 50 girls.

(A) The optimal solution to this problem = 2.125

(B) If a technical breakthrough occurred that raised the profit per unit of X to $8, would this affect the optimal solution is, = 10.625

(C) Instead of an increase in the profit coefficient X to $ 8, suppose that profit was overestimated and should only have been $ 3 is, = 10.625

Given that,

The following LP problem:

Maximize profit = 5X + 6Y

Subject to 2X+Y= 120

2X+ 3Y = 240

X,Y= 0

Maximize C = 5X + 6Y

2X+Y= 120

2X+ 3Y = 240

and x = 0, y = 0

Plot the lines on graph,

2X+Y= 120

2X+ 3Y = 240

x = 0, y = 0

So, boundary points of feasible region are (0,1.7) , (2.125,0) and (0,0)

Substitute the points in  Maximize C

At  (0,1.7)

Maximize C = 5X + 6Y

C = 5(0) + 6(1.7)

C = 0 + 10.2

Maximize C = 10.2

At  (2.125,0)

Maximize C = 5(2.125) + 6(0)

Maximize C = 10.625

At   (0,0)

Maximize C = 5(0) + 6(0)

Maximize C = 0

So, Maximum value is attained at   (2.125,0)

So, the optimal value of x is 2.125

The optimal value of y is 0

The maximum value of the objective function is 10.625

There are several ways to calculate optimal solution; one of them, is by using graphs.

The optimal value of x is 2.125

The optimal value of y is: 0

The maximum value of the objective function is: 10.625

Therefore,

The angle at the vertex of an isosceles triangle has a measure of 80 degrees.

According to the information provided:

A right triangle, also known as an isosceles triangle, is characterized by having two sides that are equal in length and an angle sum of 180 degrees.

8:5 is the ratio of the angle at the vertex to the angle at the base.

Let's say the angles come out to be 5x, 5x, and 8x.

To calculate the angle formed by the vertex, we can apply the formula as follows:

5x + 5x + 8x = 180°

18x = 180°

X = 10°

Thus, the vertex angle would be 8 x 10° = 80°

Answer:

Greek mathematician Heron of Alexandria was the first to determine the area of a triangle with three sides. Instead of using the triangle's side lengths, he provided a method that could compute a triangle's area without the need to measure any angles or other distances.

Let ABC be a triangle with lengths AB = c, BC = a, and CA = b for each of its three sides.

Triangle ABC's semi-perimeter is equal to s = (a + b + c)/2.

When the lengths of a triangle's three sides are known, the area of the triangle may be calculated using Heron's formula. To use this method, we must first determine the triangle's perimeter, which is the total distance around the triangle and is determined by summing the lengths of its three sides. There are two crucial phases in Heron's formula.

The semi perimeter of the triangle = 7 + 25 + 24 = 28 cm

2D is "flat", using the horizontal and vertical (X and Y) dimensions, the image has only two dimensions and if turned to the side becomes a line. 3D adds the depth (Z) dimension. This third dimension allows for rotation and visualization from multiple perspectives.

2D transforms happen only on 2 or sometimes even 1 axis. For example if you are in a top orthographic view and rotate an object clockwise, you are usually only changing its rotation value in one axis (z axis in Blender, y in some other software).

In a perspective view, if you are able to use a gizmo to manipulate multiple axis you may be changing the rotation value on all three axes, this would be a 3D transformation.

You can shift an object on any of the three axis easily by grabbing the arrow and sliding the object, or you can move it to an entirely new set of coordinates, that's a 3D transformation.

The place where the the line slope intersects the y-axis is known as the intersection point. where, on a line or a curve, the una crosses that location. This is demonstrated by using y = changes in different as the formula for the single direction, where m denotes the slope while c denotes the y-intercept. In the intercepting form of the equation, the line's slope (m) the y-intercept (b) are indicated. Slope and y-intercept are, respectively, m and b for equations with the intercept form (y=mx+b). Additionally, certain equations might be modified to look like slope intercepts. When y=x is written as y=1x+0, for example, the slope and una become 1 and 0, respectively.

Here,

In this case, you must first set up your equation in the "Slope intercept" form.

6x=8y+10

Because your y should be alone, add 8y to each of your sides.

8y + 6x = 10

Since subtraction is the exact reverse of addition, multiply 6 times on both sides.

8y = 6x + 10

You will now divide both sides by 8. You will be alone yourself while completing this.

y= 6/8x + 10/8

n to the power of 6, also written as n⁶, is a mathematical operation that raises the number n to the sixth power. This means that n is multiplied by itself six times.

For example, if n = 2, then n⁶ = 2 × 2 × 2 × 2 × 2 × 2 = 64.

Exponentiation is a mathematical operation that is used to represent repeated multiplication. The number that is being multiplied is called the base, and the number that represents how many times the base is being multiplied is called the exponent. In the case of n⁶, the base is n and the exponent is 6.

In general, when raising a number to a power, the result is the product of that number multiplied by itself the number of times represented by the exponent. For example, n³ = n × n × n and n⁴ = n × n × n × n.

In addition to being a mathematical operation, exponentiation also has practical applications in fields such as computer science, engineering, and physics.

For example, in computer science, exponentiation is used to perform fast computations, such as in the process of encryption and decryption. In engineering and physics, exponentiation is used to calculate rates of growth, such as in the case of compound interest and radioactive decay.

The expressions that could represent the amount Bo would pay for the game: 0.82B and  B - 0.18B

The correct options are: option (a) and option (e)

Given that the board game costs B dollars.

And the price is reduced by 18%.  

So, the discount percentage is 18%

i.e., the price is reduced by 0.18

To find out discount amount on  the board game, we multiply cost of the board game by discount percentage.

So, we get an expression for the discount amount = 0.18B

Now we calculate total price of the board game.

Subtract the discount amount from original price B

So, we get an expression for the total price of the board game.

B - 0.18B

As the  discount percentage is 18%, then the original percentage of pay is about 100 - 18 = 82%

In the given question, we have to check that it is possible to construct a triangle whose sides are 10.2 cm 5.8 cm and 4.5 cm.

The sum of the two sides must always be greater than the third side in order to determine whether or not the given sides may form a triangle.

To check this we firstly add the 10.2 and 5.8

Solution for 0.6x-12.3=7.4-1.9x equation: Simplifying

0.6x + -12.3 = 7.4 + -1.9x

Reorder the terms:

-12.3 + 0.6x = 7.4 + -1.9x

Solving

-12.3 + 0.6x = 7.4 + -1.9x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '1.9x' to each side of the equation.

-12.3 + 0.6x + 1.9x = 7.4 + -1.9x + 1.9x

Combine like terms: 0.6x + 1.9x = 2.5x

-12.3 + 2.5x = 7.4 + -1.9x + 1.9x

Combine like terms: -1.9x + 1.9x = 0.0

-12.3 + 2.5x = 7.4 + 0.0

-12.3 + 2.5x = 7.4

Add '12.3' to each side of the equation.

-12.3 + 12.3 + 2.5x = 7.4 + 12.3
