During the week of a convention, there were 608 occupied hotel rooms and 342 unoccupied hotel rooms in Lindsey's city. What perc

bagirrra123 [75]

Answer:

64%

Step-by-step explanation:

Given

Occupied = 608

UnOccupied = 342

The total number of room is the sum of these 2. So

Total Room = 608 + 342 = 950 rooms

To find percentage of rooms that were occupied, we have to divide the occupied number of rooms by the total number of rooms. Then we have to multiply that answer by 100 to get the "percentage". let's do this:

$\frac{608}{950}=0.64$

Then

$0.64*100=64$

So, 64% of the rooms were occupied.

g 7. Find Re f and Im f and find their values at the given z. (Both answers should be included) f = z⁄(z + 1), z = 4 − 5

Schach [20]

Answer:

The real and imaginary parts of the result are $\frac{1441}{1601}$ and $\frac{4}{1601}$ , respectively.

Step-by-step explanation:

Let be $f(z) = \frac{z}{z+1}$ , the following expression is expanded by algebraic means:

$f(z) = \frac{z\cdot (z-1)}{(z+1)\cdot (z-1)}$

$f(z) = \frac{z^{2}-z}{z^{2}-1}$

$f(z) = \frac{z^{2}}{z^{2}-1}-\frac{z}{z^{2}-1}$

If $z = 4 - i5$ , then:

$z^{2} = (4-i5)\cdot (4-i5)$

$z^{2} = 16-i20-i20-(-1)\cdot (25)$

$z^{2} = 41 - i40$

Then, the variable is substituted in the equation and simplified:

$f(z) = \frac{41-i40}{41-i39} -\frac{4-i5}{41-i39}$

$f(z) = \frac{37-i35}{41-i39}$

$f(z) = \frac{(37-i35)\cdot (41+i39)}{(41-i39)\cdot (41+i39)}$

$f(z) = \frac{1517-i1435+i1443+1365}{3202}$

$f(z) = \frac{2882+i8}{3202}$

$f(z) = \frac{1441}{1601} + i\frac{4}{1601}$

The real and imaginary parts of the result are $\frac{1441}{1601}$ and $\frac{4}{1601}$ , respectively.

Twice the sum of a number and 9 equals 6

Korvikt [17]

Let's make the equation.
2(N+9)=6
Let's divide both sides by 2.
n+9=3
Now subtract 9 from both sides.
n=-6
So, the number is -6.
