How do I solve this using long polynomial division?

The percentage by which the second increase of the item became 1.44 times more expensive is; 20%

Complete question is;

A store manager increased the price of an item twice by the same percent. By what percent was the second increase if the item became 1.44 times more expensive?

Let the price of the item be considered to be f(x).

Let p be the percent increase. Thus;

f(x) = xp²

We are told that at the second increase, the item became 1.44 times more expensive. Thus;

1.44x = xp²

1.44 = p²

p = √1.44

p = 1.2

Now, in percentage form, p = 120%

This means that the second increase was 20% more than the first.

The values of a and b from the quadratic equation x² + (13/2)*x + 15/2 = 0 are:a = -10/13 and b = -3/13 respectively.

For a general quadratic equation:a*x² + b*x + c = 0

The solutions are:

\(x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}\)

In this case, we have the quadratic equation:

x² + (13/2)*x + 15/2 = 0.

Replacing that in the quadratic formula for the solutions, we will get:

\(x = \frac{-13/2 \pm \sqrt{(13/2)^2 - 4*1*15/2} }{2*13/2}\\\\

x = \frac{-6.5 \pm 3.5 }{13}\)

Then the two solutions are:

x = (-6.5 - 3.5)/13

= -10/13

x = (-6.5 + 3.5)/13

= -3/13

Therefore, the solution to the quadratic equation is = -10/13 and b = -3/13

The specific policies regarding the use of SAT/ACT scores for college admissions can vary from school to school. It's best to consult with your school's admissions office or check their official website to understand their specific requirements and policies.

In general, many schools consider the highest score achieved by an applicant, also known as superscoring. Superscoring involves considering the highest section scores from multiple test administrations to calculate a composite or total score. This allows students to showcase their best performance across multiple test sittings.

However, some schools may have different policies and may consider the most recent score or use a different method to evaluate test scores. It's important to reach out to your school's admissions office or refer to their official documentation to determine how they handle SAT/ACT scores for admissions purposes.

Answer:

Image result for Eight cakes cost 2. 40. How much do 20 cakes cost

How much should I charge for my cake?

First, estimate how many hours is this cake going to take - 5 hours.

Then, calculate the cost of ingredients - $20.

Next, determine the labor cost - $20 x 5 = 100.

Add utility cost - $5.

Sundry cost (small cost) - $5.

Then, calculate the total cost: 20 + 100 + 5 + 5 = $130.

Explanation:

Answer: 20 + 100 + 5 + 5 = $130.

The equivalent of each unit in SI of Norah's Ark was lenght=137.16m,hieght =13.71m and width= 22.86m and Solomon’s temple at Jerusalem was  lenght =27.432m,hieght =13.71m and width= 9.144m.

In the olden days, God gave Noah the dimensions for the ark in cubits. “This is how you are to make it: the length of the ark 300 cubits, its breadth 50 cubits, and its height 30 cubits” (Genesis 6:15).

The dimensions for the Jerusalem Temple King Solomon built: “60 cubits long, 20 cubits wide and 30 cubits high” (1 Kings 6:2).

the SI unit of length is Meters. Therefore 1 Cubit= 0.4572m;

Calculating  The dimensions of Noarh's Ark;

Length= 300 X 0.4572= 137.16m

Width=50 * 0.4572=22.86m

Height=30*0.4572=13.716m

Calculating the dimensions of  Solomon’s temple;

Length= 60 X 0.4572= 27.432m

Width=20 * 0.4572=9.144m

Height=30*0.4572=13.716m

Based on the fact that Rafi made a diagram to compare Newton's universal law of gravitation with Einstein's general theory of relativity, the label that belongs in the area marked X is option B. gravity causes objects to fall to the ground.

A coherent account of gravity as a geometric property that pertains to space as well as time, or four-dimensional spacetime, is said to be provided by general relativity, which generalizes special relativity and improves Newton's law of universal gravitation.

Note that the premise upon which Einstein based his theory was that it is one that is based on gravity and acceleration have the same effect and cannot be separated from one another. According to his findings, light can and need or must fall in a gravitational field and an accelerating reference frame.

Hence, based on the above,  the right label is option B. gravity causes objects to fall to the ground.

Encontrando y resolviendo un sistema de ecuaciones, veremos que hay 9 camionetas y 3 autos.

Sabemos que hay 12 vehículos en el camión.

Definamos:

tal que a + c = 12

La masa total será:

a*2 ton + c*3 ton

Y sabemos que el camión lleva 33 toneladas, entonces tenemos:

a*2 ton + c*3 ton = 33 ton

Así encontramos el sistema de ecuaciones:

a + c = 12

a*2 ton + c*3 ton = 33 ton

Para resolverlo, primero aislamos una de las variables en una de las ecuaciones, aislemos a en la primera:

a = 12 - c

Ahora reemplazamos esto en la otra:

(12 - c)*2 ton + c*3 ton = 33 ton

24 ton + c*1 ton = 33 ton

c*1 ton = 9 ton.

c = 9

Es decir, hay 9 camionetas.

Entonces los 3 vehículos restantes son autos.

Explanation:

The probability of event B occurring based on the question requirements is P(B), is 0.75.

For two independent events A and B, the probability of both A and B occurring, P(A and B), is the product of their individual probabilities, P(A) and P(B).

So, P(A and B) = P(A) * P(B).

Given P(A) = 0.64 and P(A and B) = 0.48, you can solve for P(B) by dividing P(A and B) by P(A), i.e., P(B) = P(A and B) / P(A).

Substituting the given values, P(B) = 0.48 / 0.64 = 0.75.

Therefore, the probability of event B occurring, P(B), is 0.75.
