Answers

Answer 1

Answer:

Step-by-step explanation:

No se si esto deberia ser mas dificil pero aqui voy:

Pregunta 1.

27 - 15 = 12

El numero es 12

Pregunta 2.

27 - 5= 22 dividido 2 = 11

El numero que pensastes es 11

Pregunta 3.

32 - 8 = 24 dividido 2 = 12

El tiene 12 años

Use el metedo reversa.

Answer 2

Construyendo y resolviendo las ecuaciones, encontramos que:

1. El numero es 12.2. El numero es 11.3. La edad de Juan es 12.

---------------

Ejercicio 1

El número es x.Sumando 15, tenemos x + 15 Obtuve 27, entonces:

[tex]x + 15 = 27[/tex]

[tex]x = 27 - 15 = 12[/tex]

El numero es 12.

---------------

Ejercicio 2

El número es x.Multiplicando por 2, tenemos 2x. Sumando 5, tenemos 2x + 5.Obtuve 27, entonces:

[tex]2x + 5 = 27[/tex]

[tex]2x = 22[/tex]

[tex]x = \frac{22}{2}[/tex]

[tex]x = 11[/tex]

El numero es 11.

---------------

Ejercicio 3

La edad es x.Doble de la edad es 2x.Sumando 8, tenemos 2x + 8.Obtuve 32, entonces:

[tex]2x + 8 = 32[/tex]

[tex]2x = 24[/tex]

[tex]x = \frac{24}{2}[/tex]

ibuprofen left in the persons system. How long will it take until there is only 25 mg

of ibuprofen left in the person's system? Show all work and round your answer to

three decimal places.

Answers

Answer:

It will take 3 hours 46 minutes and 8 seconds to use 375 mg of ibrufen.

Step-by-step explanation:

An adult takes 400 mg of ibuprofen. Two hours later, there is 201.6 mg of

ibuprofen left in the persons system

This means that in 2 hours time

400- 201.6= 198.4 mg was used up.

We need only 25 mg in the system

so 400- 25= 375 mg  time is needed

time          mg

2 hour      198.4

x                375

Using the cross product rule

x= 375*2/198.4

x= 3.780 hrs

Which means 3 hours and (0.78* 60)= 46.8 minutes.

It will take 3 hours 46 minutes and 8 seconds to use 375 mg of ibrufen.

BM 1: 2. Find the value of angles x and y in circle A.
.X=
150°
175°
y =
to

Answers

Answer:

x = 35

y = 17.5

Step-by-step explanation:

By Central angle and its corresponding arc theorem:

x° = 360° - (175° + 150°)

x° = 360° - 325°

x° = 35°

x = 35

By inscribed angle theorem:

[tex]y \degree = \frac{1}{2} x \\ \\ y\degree = \frac{1}{2} \times 35 \degree \\ \\ y\degree = 17.5 \degree \\ \\ y \: = 17.5[/tex]

Answer:

x=35         y=17.5

Step-by-step explanation:

This problem wants you to find the angles of an inscribed and central angle.

Note: central angles are angles that have radii as there sides and the center (of the circle) as its center. Inscribed angles are angles that have chords as there sides and there vertex as a point on a circle.

I will by find the measure of the missing arc. To do this is simple, Just add 175+150 and subtract from 360,

175+150= 325          

360-325=35

So, the missing arc length is 35. X is a central angle and central angles are equal to the arc length. This means that,

x=35

Lastly, we need to find y, an inscribed angle. Inscribed angles are half of the arc length. So, the measure of y is 17.5

y=17.5

Write the polynomial in standard form then name the polynomal based on its degree and number of terms 2-11x2-8x + 6x2

Answers

Question

Write the polynomial in standard form then name the polynomal based on its degree and number of terms 2-11x²-8x + 6x²

Answer:

Standard form: -5x²- 8x + 2

name: Quadratic polynomial

Step-by-step explanation:

Given polynomial

2-11x²-8x + 6x²

To write this polynomial in standard form,

i. First simplify it

Collect like terms

2 - 11x² + 6x² - 8x

Add the second and fourth terms

2 - 5x² - 8x

ii. Arrange the terms in the polynomial in order of decreasing order of x.

In other words, the term which has the highest order of x is written first followed by the term with the next highest order of x and so on.

In this case, the term with the highest order of x is the second term which is given by -5x² followed by -8x and then 2.

Therefore, the standard form of the given polynomial is

-5x²- 8x + 2

The degree of a polynomial which is in standard form is the order of its first term.

In this case, the order of the first term is 2. This means that the degree of the polynomial is 2.

Since the degree of the polynomial is 2 and it has three terms, this is a quadratic polynomial.

Find the area of the figure above.
[?] cm2

Answers

Answer:

We first ALWAYS have to split the figure apart from each other,

lets split it into a triangle and a square!

Let's find the area of the triangle:

20(height) x 20(base) = 400!

400 x 1/2 (just dividing by 2) = 200!

*Remember* Formula of a triangle is:

B(base) x H(height) x 1/2 (basically dividing by 2)

Now time to find the area of the square!

20 x 20 = 400!

Now let's add both their areas:

400 + 200 = 600!

Step-by-step explanation:

600cm2 is your answer.

The figure has an area of 600 square centimeters.

In this question we need to determine the area of the entire figure, this area is the sum of the areas of a square and two symmetric right triangles, defined by respective formulas, that is:

[tex]A = A_{s} + 2\cdot A_{t}[/tex] (1)

Where:

[tex]A[/tex] - Total area, in square centimeters.[tex]A_{s}[/tex] - Square area, in square centimeters.[tex]A_{t}[/tex] - Triangle area, in square centimeters.

By applying area formulas for squares and triangles, we expand (1):

[tex]A = x^{2} + \frac{1}{2}\cdot x\cdot y[/tex] (2)

Where:

[tex]x[/tex] - Side length of the square, in centimeters.[tex]y[/tex] - Height of the two right triangles, in centimeters.

If we know that [tex]x = 20\,cm[/tex] and [tex]y = 20\,cm[/tex], then the area of the figure is:

[tex]A = \frac{3}{2}\cdot (20\,cm)^{2}[/tex]

[tex]A = 600\,cm^{2}[/tex]

The figure has an area of 600 square centimeters.
