The suns photosphere
Blababa [14]

Answer:

The photosphere is the visible surface of the Sun that we are most familiar with. Since the Sun is a ball of gas, this is not a solid surface but is actually a layer about 100 km thick (very, very, thin compared to the 700,000 km radius of the Sun).

Paradichlorobenzene, c6h4cl2 c 6 h 4 c l 2 , is a component of mothballs. A solution of 2. 00 g g in 22. 5 g g of cyclohexane bo
Nimfa-mama [501]

The value of kb of cyclohexane in the given question is; kb = 2.82 °C/m

<h3>Understanding Molality of a Solution</h3>

Molality of solution = (Number of moles of C₆H₄Cl₂)/(Mass of Cyclohexane)

Now;

Number of moles of C₆H₄Cl₂ = Mass/molar mass = 2g/147 g/mol

Number of moles of C₆H₄Cl₂ = 0.0136 mol

Molality of solution = 0.0136/(22.5 * 10⁻³ kg)

Molality of solution = 0.6 m

Now, to find kb for cyclohexane, we will use the formula;

T_b(solution) - T_b(solvent) = kb × molality of solution

Thus;

82.39 - 70 = kb * 0.6

kb = (82.39 - 70)/0.6

kb = 2.82 °C/m

Two numbers differ by 8 if their product is 713 then the sum of the two numbers is.
const2013 [10]

The sum of the two numbers is equal to 70.

  • Let the first number be x.
  • Let the second number be y.

In this exercise, you're required to find two numbers by translating the word problem into an algebraic expression and then solving for the unknown variables (x and y).

Translating the word problem into an algebraic expression, we have;

Two numbers differ by 8:

x-y=8    ....equation 1.

The product of the two numbers is 713:

xy=713    ....equation 2.

To calculate the sum of the two numbers:

First of all, we would solve for each of the unknown variables (x and y).

From eqn. 1, we have:

x=8+y   ....equation 3.

Substituting eqn. 3 into eqn. 2, we have:

y(y+8)=713\\\\y^2+8y=713\\\\y^2+8y-713=0

Solving the quadratic equation by factorization, we have:

y^2-31y +23y-713=0\\\\y(y-31)+23(y-31)=0\\\\(y+23)(y-31)=0

y = -23 or 31.

For the value of x, when y = 31:

x=8+31

x = 39

Now, we can calculate the sum of the two numbers:

x+y=39+31=70

explica, con un ejemplo, por lo menos cinco cualidades positivas de ti mismo (de tu carácter, mentales, en el terreno de las rel
larisa86 [58]

Answer:

Un cualidad en mi caracter es la templanza. Me cuido mucho de lo que vaya a comer. La segunda cualidad positiva mental es que lo que me propongo logro. En el terreno de las relaciones tengo dos. Por ejemplo con mis padres soy bueno hijo y con mi amiga siempre dispuesto de ayudar. En mi grupo de escuela me conocen como una persona amable. Finalmente, en la iglesia yo soy el que ayuda a los ancianos.

Explanation:

One quality of my character is temperance. I take good care of what I am going to eat. The second positive mental quality is whatever I set to accomplish, I will accomplish. In the personal relationships arena, I have two. For example, I am a good son with my parents and my friend I help her in whatever she may need. Within my school, people know me as amicable. Finally, in my church, I help the elderly.

Y = 3x
Anna71 [15]

Answer:

-12

Explanation:

We are given information to solve for 2 variables x and y. To solve this I substituted 3x for y in the equation 5x - 4y = 21

So substituting gets us 5x - 4(3x) = 21

and we can solve the equation for x

5x - 12x = 21

-7x = 21

x = -3

Now that we have found x, we can find y simply by putting it in the equation y = 3x

y = 3(-3) = -9

Once we have both variables, we can find the answer to x + y

-3 + -9 = -3 - 9 = -12

So the answer to the question

x + y = -12
