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.

Answer:

(6, 0)

Step-by-step explanation:

Answer:

To find the principal amount, you can use the formula for continuously compounded interest:

A = Pe^(rt)

where A is the final account balance, P is the initial principal (or starting) amount, r is the interest rate, and t is the time (in years) for which the interest is being calculated.

Substituting in the given values:

1,433,785.18 = P * e^(0.054 * 12)

To find P, we can divide both sides by e^(0.054 * 12)

P = 1,433,785.18 / e^(0.054 * 12)

The y-intercept of a function is the value of y = -9 when x = 0. Therefore, the functions have the same y-intercept.

How to find y-intercept?

A function's y-intercept is the value of y at x = 0. It is, in other words, the location of the graph's intersection with the y-axis.

the point on a line, curve, or surface where the y-axis touches that point.

Therefore,

Function 1:

r = 5 / 8 t - 9

r = 5 / 8 (0) - 9

r = -9

hence, the y-intercept is -9

(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,

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 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.

Then the value of a will be,

→ 2 + a = 7

→ a + 2 = 7

→ a = 7 - 2

→ [ a = 5 ]

Hence, the value of a is 5.
