The equation y=1/9x relates proportional quantities x and y.

What is the value of x when y is 4?

Answers

Answer 1

Answer:

x=36 when y=4

Step-by-step explanation:

When y=4, you have to multiply 1/9x by 9 to make x whole and to truly figure out how much it is worth. So if 1/9x =4, you need to multiply 4x9

4x9=36

x=36

Solve x2 - 16x + 60 = -12 by completing the steps. First, subtract 60 from each side of the equation. Next, add 8 ⇒ 64 to each side of the equation to complete the square. Now, write x² - 16x + 64 = -8 as ✔ (x - 8)² = -8 Take the square root of both sides to get the solutions

Answers

Answer:

Step-by-step explanation:

Given  x^2 - 16x + 60 = -12

Using the completing the square method to find x;

subtract 60 from both sides

x2 - 16x + 60-60 = -12-60

x2 - 16x  = -72

Add square of the half of the coefficient of x to both sides

x2 - 16x + (1/2(-16))²  = -72 +  (1/2(-16))²

x^2 - 16x +64 = -72+64

(x-8)² = -8

Take the square root of both sides

√(x-8)² = √-8

x - 8 = ±√8i

x =  ±√8i+8

x =  ±2√2i+8

The solution of the given equation is:  [tex]x = 8+\sqrt{-8}[/tex]  and  [tex]\\x = 8-\sqrt{-8}[/tex].

Given that:

Equation:  [tex]x^2 - 16x + 60 = -12[/tex]

Simplify the above equation as:

x² - 16x + 60 = -12

x² - 16x = -12 - 60

x² - 16x = -72

Add 64 to each side of the equation to complete the square.

x² - 16x + 64 = -72 + 64

x² - 16x + 64 = -8

Write x² - 16x + 64 as (x - 8)² since it is a perfect square trinomial.

(x - 8)² = -8

Take the square root of both sides to get the solutions.

[tex]x - 8 = \±\sqrt{-8}\\x = 8\±\sqrt{-8}\\x = 8+\sqrt{-8}\\x = 8-\sqrt{-8}[/tex]

where i is the imaginary unit.

Hence, the value of x are:  [tex]x = 8+\sqrt{-8}[/tex]  and  [tex]\\x = 8-\sqrt{-8}[/tex].

Step-by-step explanation:

Given

[tex]\frac{2}{5\sqrt{3} }[/tex]

To rationalise the denominator, multiply the numerator/ denominator by [tex]\sqrt{3}[/tex]

= [tex]\frac{2\sqrt{3} }{5\sqrt{3}(\sqrt{3}) }[/tex]

Find the values of x and y. 3x - 5 5y - 4 y + 12​

Answers

The values of x and y in the equilateral and Isosceles triangles are 7 and 4 respectively.

What is an equilateral triangle?

An equilateral triangle is a triangle that has all its sides equal to each other.

Therefore,

3x - 5 = 5y - 4 (equilateral triangle)

3x - 5y = 1

Therefore,

y + 12 = 3x - 5 (Isosceles triangle)

y - 3x = - 17

Hence,

3x - 5y = 1

- 3x + y = - 17

-4y = -16

y = -16 / -4

y = 4

Therefore,

3x = 1 + 5(4)

3x = 21

x = 21 / 3

x = 7

Após recuperar-se de uma cirurgia, o treinador da corredora Andrea estipulou um plano de treinamento diário: correr 500 metros no primeiro dia e aumentar 200 metros por dia, a partir do segundo, até que ela atinja 10 km. Andrea pretende correr 10 km na maratona do Rio de Janeiro, no início do próximo ano. Em quantos dias de treinamento Andrea atingirá 10 km?

Answers

Explicación paso a paso:

La distancia recorrida el primer día = 500 m

Si aumenta la distancia en 200 m diariamente, entonces el total corrido diariamente formará una progresión aritmética con el último término de 10 km (10,000) como se muestra;

500, (500 + 200), (500 + 200 + 200) ... 10,000

500, 700, 900 ... 10,000

para que sepamos el número total de días usados ​​para la carrera, usaremos la fórmula para calcular el enésimo término de una secuencia aritmética como se muestra;

[tex]T_n = a+(n-1)d[/tex] where;

n es el número de términos

a es el primer término de la secuencia

d es la diferencia común

Dado a partir de la secuencia:

a = 500

Tn = 10,000

d = 700-500 = 900-700 = 200

Sustituir en la fórmula y calcular el valor de n

[tex]10,000 = 500+(n-1)*200\\10,000 = 500+(200n-200)\\10,000 = 500-200+200n\\200n = 10,000-300\\200n = 9,700\\n = 9,700/200\\n = 48.5[/tex]

Andrea habría alcanzado los 10.000km tras 48,5 días de carrera

Suppose there is a 1.7f drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 49.9f what will be the temperature when the plane reaches am altitude of 4,000ft?? The temperature will be_____F (type an integer or a decimal)

Answers

Answer:

[tex]43.1 ^{\circ}F[/tex]

Step-by-step explanation:

Give that for every 1000 feet increase in the height there is a drop of [tex]1.7 ^{\circ}F[/tex] in temperature.

So, the rate of temperature drop with respect to height, R = 1.7/1000 [tex]^{\circ}F/\text{ft}[/tex].

If the change in height is [tex]\Deltah[/tex][tex]\Delta h[/tex] feet, the temperature drop,

[tex]\Delta T= \Delta h R \;^{\circ}F\cdots(i)[/tex]

The temperature on the ground is 49.9 [tex]^{\circ}F[/tex].

At the ground, the height is 0, so the change in height, \Delta h when the plane reaches an altitude of 4,000 feet, is

\Delta h =4000-0=4000 feet

Now, from equation (i), the temperature drop

[tex]\Delta T= 4000 \times \frac {1.7}{1000}=6.8\;^{\circ}F.[/tex]

Hence, the temperature at an altitude of 4000 feet [tex]= 49.9-6.8=43.1 \;^{\circ}F[/tex].

Answers

Answer: 64462 visitors

Step-by-step explanation:

In September, a website had 12,514 visitors.

In October, the website had 13,460 more visitors than it did in September. This will be:

= 12514 + 13460

= 25974

The website had the same number of visitors in November as it did in October.

September = 12514 visitors

October = 25974 visitors

November = 25974 visitors

Total visitors = 12514 + 25974 + 25974

= 64462 visitor
