Answer:

P + Q = 1

Step-by-step explanation:

Given: \frac{1+\sqrt{3} }{1-\sqrt{3} }  = P - \sqrt{Q}

This is a question on surd, so we need to rationalize the denominator to have;

\frac{1+\sqrt{3} }{1-\sqrt{3} }  * \frac{1+\sqrt{3} }{1+\sqrt{3} } = \frac{1+\sqrt{3}+\sqrt{3}  + 3}{1+\sqrt{3}-\sqrt{3} -3 }

   = \frac{4+ 2\sqrt{3} }{1-3}

   = \frac{4+2\sqrt{3} }{-2}

   = -2 - \sqrt{3}

Thus,

-2 - \sqrt{3} = P - \sqrt{Q}

⇒ P = -2 and Q = 3

Therefore, the value of P + Q = -2 + 3

                                                 = 1

Thus,

P + Q = 1

In a movie theater, the number of seats in a row is 8 greater than the total number of rows. How many rows are in the movie thea
Harman [31]

Answer:

26 rows

Step-by-step explanation:

this is like a rectangle length×width situation.

seats per row = s

number of rows = r

s × r = 884

s = r + 8

so, we can use e.g. the second equation in the first :

(r + 8) × r = 884

r² + 8r = 884

r² + 8r - 884 = 0

the general solution to such a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = r

a = 1

b = 8

c = -884

r = (-8 ± sqrt(8² - 4×1×-884))/(2×1) =

= (-8 ± sqrt(64 + 3536))/2 = (-8 ± sqrt(3600))/2 =

= (-8 ± 60)/2 = -4 ± 30

r1 = -4 + 30 = 26

r2 = -4 - 30 = -34

a negative number did not make any sense for the number of rows, so r = 26 is our answer.

How to add fractions? with unlike denominators
stellarik [79]

Answer:

The recipe calls for 19/12 or 1 7/9 cups.


Step-by-step:

In order to get this answer, we have to add all three fractions together. First, we have to find the LCM (Least Common Multiple) between the three denominators:

2: 2, 4, 6, 8, 10, 12

3: 3,6,9,12

4: 4,8,12

The LCM between these three denominators is 12.

4x3=12

2x6=12

3x4=12

You now multiply the numerator by the same number you multiplied by for the denominator in order to get 12:

3/4 becomes 9/12

1/2 becomes 6/12

1/3 becomes 4/12

We now add all the fractions together:

9/12+6/12+4/12= 19/12

We got 19/12 but the answer is an improper fraction so we turn it into a mixed number:

12x1=12 (7 remaining)

This is written as 1 7/12.

Hope this helps! :)
