The value of the fraction is A = 20 / 9

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given data ,

Let the fraction be represented as A

Now , the first fraction is p = 5/6

Let the second fraction be q = 3/8

Now , the equation is A = p/q

On simplifying , we get

A = ( 5/6 ) / ( 3/8 )

A = ( 5/6 ) x ( 8/3 )

On further simplification , we get

The fraction A = ( 20 / 9 )

Hence , the fraction is A = 20/9

The fact that both rays are equal in the case at hand is not given, hence the incorrect statement will be (A) AB = AC.

By selecting a curve that is perpendicular to the wavefronts of the actual light and points in the direction of energy flow, one can create an idealized geometrical model of light or other electromagnetic radiation known as a ray in the field of optics.

By segmenting the actual light field into discrete rays that can be computationally propagated across the system using ray tracing techniques, rays are used to mimic the propagation of light through an optical system.

As a result, even extremely complicated optical systems can be mathematically or computationally investigated.

For as long as light waves travel through and around objects whose dimensions are significantly larger than the light's wavelength, approximate solutions to Maxwell's equations are appropriate for use in ray tracing.

So, in the given situation it is nowhere given that both rays are equal, and hence the wrong statement will be AB = AC.

Therefore, the fact that both rays are equal in the case at hand is not given, hence the incorrect statement will be (A) AB = AC.

The required derivative of f(x) = ln(1 - x) is f'(x) = -1 / (1 - x).

A derivative is a two-party contract whose price or value is based on an underlying asset. Futures, options, forward contracts, and swaps are the four most popular types of derivatives. It is a financial instrument whose price and value are determined by the underlying assets.

The derivative of the natural logarithmic function is given by:

d/dx [ln(u(x))] = 1/u(x) * du/dx

So, to find the derivative of f(x) = ln(1 - x), we need to find the derivative of the inside function, which is 1 - x:

f'(x) = 1/[1 - x] * d/dx [1 - x]

= 1/[1 - x] * (-1)

= -1 / (1 - x)

So the derivative of f(x) = ln(1 - x) is f'(x) = -1 / (1 - x).

No, The point (30, 61) does not lie on the given line y  = 2x - 1.

The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.

Given that,

The line,

y = 2x -1

To check if the point (30, 61) is on the line y = 2x - 1, we need to substitute x = 30 and y = 61 into the equation and see if the equation holds true.

So, we have:

y = 2x - 1

61 = 2(30) - 1

61 = 60 - 1

61 = 59

Answer:

Step-by-step explanation:

The percent yield formula is used to calculate the efficiency of a chemical reaction in producing a desired product. It is defined as the ratio of the actual yield of a product to its theoretical yield, expressed as a percentage.

The formula for percent yield is:

Percent Yield = (Actual Yield / Theoretical Yield) * 100%

where:

Actual Yield is the amount of product actually produced in the reaction.

Theoretical Yield is the maximum amount of product that could be produced in a reaction under ideal conditions, calculated from the stoichiometry of the reaction.

By using this formula, you can determine how well a reaction is performing and identify areas for improvement to increase the yield of the desired product.

(1) 4 notebooks,3 pencils, have change $12;

(2)3 notebooks, 5 pencils, have no change.

Step-by-step explanation:

set student buy x notebooks and y pencils,

60x+36y≤360

if x=3, 180+36y≤360

         36y≤180

             y≤5

and y≥3, so y={3,4,5}

(1)when y=3, 60x≤360-36x3=252, x≤4.2,so x=4,

and change=360-36x3-60x4=12

(2)when y=4, 60x≤360-36x4=216, x≤3.6,so x=3,

and change=360-36x4-60x3=36, since student have to spend as much as possible of his money, $36 can buy a pencil, so this is not accepted.

(3)when y=5, 60x≤360-36x5=180, x≤3, so x=3,

and change =360-36x5-60x3=0

The student has two ways to spend his money on notebooks and pens. In one option, she can buy 4 notebooks and 3 pens and in the other option she can buy 3 notebooks and 5 pens.

To find the student's possibilities to buy pens and notebooks we must take into account his total budget of $360. Additionally, the values of the notebooks and pens that are: $60 and $36 respectively.

We must multiply the value of the notebooks by the number of notebooks that we believe the student can buy, this would be a range between 3 and 4 notebooks. Additionally, once we decide the number of notebooks we can divide the remaining money in the value of the pens to find the number of pens that the student can buy. According to the above:

The weight of Alicia's camera is 8/5 kg. We can record this value in the table.

A fraction is a number that represents a part of a whole. It is expressed as a ratio of two numbers, where the top number is called the numerator and the bottom number is called the denominator.

We need to record the weight of Alicia's camera in the table. We know that the weight of her lunch is greater than the weight of her camera, and we know that the weight of her lunch is 2 kg. Therefore, the weight of her camera must be less than 2 kg.

We are also given that the weight of her camera is 1\dfrac35 kg. To convert this mixed number to an improper fraction, we can multiply the whole number (1) by the denominator of the fraction (5) and add the numerator (3), and then put the result over the denominator:

[tex]1\dfrac35 = \dfrac{1\times5+3}{5} = \dfrac{8}{5}[/tex]

Since the two parallel lines are cut by a transversal and m∠3 = 41°, the measure of angles m∠6 and m∠8 include the following:

m∠6 = 139°.

m∠8 = 139°.

In Mathematics, parallel lines are two lines that are cut through by a transversal and they always have the same (equal) distance apart and never meet.

In Mathematics, the Alternate Interior Angles Theorem states that when two (2) parallel lines are cut through by a transversal, the alternate interior angles that are formed are congruent:

m∠3 = m∠5 (alternate interior angles)

m∠5 + m∠6 = 180° (linear pair postulate).

41° + m∠6 = 180°.

m∠6 = 180° - 41°

m∠6 = 139°

m∠6 = m∠8 (vertical angles theorem).

Answer:

The probability that two independent events will both occur can be calculated by multiplying the probabilities of the individual events. If event A has probability p(A) and event B has probability p(B), then the probability that both events A and B occur is given by:

p(A and B) = p(A) * p(B)

This relationship holds because the occurrence of event A does not affect the occurrence of event B, and vice versa. Hence, the two events are considered to be independent.

For example, if event A has a probability of 0.6 of occurring and event B has a probability of 0.7 of occurring, then the probability that both events will occur is 0.6 * 0.7 = 0.42.

The surface area of a square pyramid net can be found by adding the areas of the base and the four triangular faces.

First, find the area of the base by multiplying the length and width of the square base.

Area of base = length × width

Next, find the area of one of the triangular faces by using the formula:

Area of triangle = 0.5 × base × height

Since there are four triangular faces in a square pyramid, multiply the area of one triangle by four to find the total area of the triangular faces.

Area of triangular faces = 4 × (0.5 × base × height)

Finally, add the area of the base and the area of the triangular faces to find the total surface area of the square pyramid net.

Surface area = Area of base + Area of triangular faces

= (length × width) + (4 × (0.5 × base × height))

= (length × width) + (2 × base × height)

So, the surface area of a square pyramid net is the sum of the area of the base and the area of the four triangular faces.
