Answer:

4.9%

Step-by-step explanation:

There are a total of 20 marbles.

The probability that the first marble is green is 8/20.

The probability that the second marble is green is 7/19.

The probability that the third marble is green is 6/18.

The total probability is:

P = (8/20) (7/19) (6/18)

P ≈ 0.049

The probability is 4.9%.

Person to get this question right will get brainliest: If I have 4 moles of a gas at a pressure of 5.6 atm and a volume of 12 li
dybincka [34]

Answer:

If i have three moles of a gas at a pressure of 5.6 atm and a volume of 3 liters, what is the temperature ?

We have the following data:

n (number of moles) = 3 moles

P (pressure) = 5.6 atm

V (volume) = 12 L

T (temperature) = ? (in Kelvin)

R (gas constant) = 0.082 atm.L / mol.K

We apply the data above to the Clapeyron equation (gas equation), let's see:

Answer:

The temperature is approximately 205 Kelvin

jalil and Victoria are each asked to solve the equation ax – c = bx + d for x. Jalil says it is not possible to isolate x becaus
Pie

Answer:

x = \frac{d+c}{a - b}

Step-by-step explanation:

Equation: ax – c = bx + d

Jalil says it is not possible to isolate x because  x has a different unknown coefficient.

Victoria t. Victoria believes there is a solution

Solving the equation:

ax-c = bx + d

ax - bx= d+c

(a - b)x = d+c

x = \frac{d+c}{a - b}

So, this shows x can be isolated .

Victoria was right .

It was not possible to isolate x if the coefficients of x would be same .

But in the given equation the coefficients of x are not same .

So, Victoria is right.

How do I solve equations with a variable to the power of something (give steps please)
lozanna [386]

Answer:

Step-by-step explanation:

Factoring will reveal the solution. So we divide the equation by the greatest common factor of the terms and use that factor as the coefficient. In this case the greatest common factor is just x.

2x^2+5x

x(2x+5) so the equation will equal zero when either of those expressions is zero because zero times anything is zero. x=0 and x=-5/2
