Step-by-step explanation:
Steam distillation is a separation process which consists in distilling water together with other volatile and non-volatile components.
Fractional distillation is the separation of a mixture into its component parts, or fractions.
A technique for the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates.

a2+(b−c); a=−8, b=17, c=21
Answer:
-20
Step-by-step explanation:
a2 + ( b-c)
rewrite the equation
2 * a + ( b - c )
a = -8
b = 17
c = 21
substitute in the given values
(-8) 2 + ( (17) - (21) )
simplify and solve
-16 + ( 17-21)
= -16 + (-4)
= -16 -4
=-20

The result of adding a complex number to its conjugate is “an integer/a pure imaginary number/a real number/a whole number” and the result of subtracting a complex number from its conjugate is “an integer/a real number/a pure imaginary number/a whole number”
Answer:
If Z is a complex number:
Z = a + b*i
where a and b are real numbers, and i is an imaginary number.
Then "a" is the real part.
"b*i" is the imaginary part.
The conjugate of Z is:
Zc = a - b*i
So the sign of the imaginary part changes.
Then:
Sum:
Z + Zc = (a + bi) + (a - bi) = 2*a + 0 = 2*a
and remember that a is a real number, then 2*a is also a real numer.
The correct answer is "A real number".
Difference:
Z - Zc = (a + bi) - (a - bi) = 2b*i
and this is a pure imaginary number, so here the correct answer is: "a pure imaginary number"
Answer: a pure imaginary number
explanation:
The sum of a complex number and its conjugate will always be two times the real part of that complex number.
Z=a+b*i
where a and b are real numbers, and i is an nonexistent number.
Then a is the real part.
"b*i" is the imaginary part.
The connection of Z is:
Zc = a - b*i
So the sign of the imaginary part changes.
Sum:
Z + Zc = (a + bi) + (a - bi) = 2*a + 0 = 2*a
and remember that a is a real number, then 2*a is also a real number.
The correct answer is "A real number".
Difference:
Z - Zc = (a + bi) - (a - bi) = 2b*i
Given y2 + 5y - 6 = (y + p)(y +q) find the
values of p and q.
Answer:
p = 6, q = - 1
Step-by-step explanation:
Factor the left side and compare to right side
y² + 5y - 6
Consider the factors of the constant term (- 6) which sum to give the coefficient of the y- term (+ 5)
The factors are + 6 and - 1, since
6 × - 1 = - 6 and 6 - 1 = + 5, thus
y² + 5y - 6 = (y + 6)(y - 1)
Compare with (y + p)(y + q) , then
p = 6 and q = - 1
what is 7(1 - 8n)???
Answer:
7-56n
Step-by-step explanation:
By using the distributive property you multiply the 7 to the 1 which equals 7. Then you distribute the 7 to the -8n which gives you -56n becaus emultiplying a negative and a possitive gives you a negative.
The required solution is -56n+7.
It is required to find the solution.
What is algebra?A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.
Given:
Rearrange terms
7(1 - 8n)
=7(-8n+1)
Then distribute by multiplying 7 we get,
-56n+7
Therefore, the required solution is -56n+7.

Hey there!☺
[tex]Answer:\boxed{t=2}[/tex]
[tex]Explanation:[/tex]
[tex]5t-9=-3t+7[/tex]
Let's start by adding 3t to both sides of the equation.
[tex]5t-9+3t=-3t+7+3t\\8t-9=7[/tex]
Now let's add 9 to both sides of the equation.
[tex]8t-9+9=7+9\\8t=16[/tex]
Now let's divide both sides by 8.
[tex]\frac{8t}{8} =\frac{16}{8}[/tex]
Now let's simplify 16/8.

if the selling price of 16 water bottles is equal to the cost price of 17 water bottles find the gain percent earned by the dealer
Answer:
let cp of 17 water bottle is x
cp of 1 water bottle = x/17
from the question
sp of 16 water bottles = x
sp of 1 water bottle = x/16
profit = sp -cp
= x/16 - x/17
= x/272
profit % = profit /cp * 100%
= (x/272)/ (x/17) * 100%
= 6.25%

Arranging the data in ascending order.
56,72,87,89,93.
n=5
Median =[(n+1)/2]th observation.
=[(5+1)/2]th observation
=3rd observation

To rent a certain meeting room, a college charges a reservation fee of $39 and an additional fee of $5.80 per hour. The film club wants to spend at most $73.80 on renting the meeting room.
What are the possible amounts of time for which they could rent the meeting room?
Use t for the number of hours the meeting room is rented, and solve your inequality for t.
Answer:
The inequality is x less than or equal to 6. So the amount of hours they can rent it is 6 hours or less.
Step-by-step explanation:
5.80x + 39 <_ 73.80 ----> subtract 39 on both side to get ---> 5.80x <_ 73.80 -----> then divide by 5.80 on both sides to get ---> x <_ 6.
