24i+16
A. Real
B.purely
C.complex
D. Not enough information
Answer:
Step-by-step explanation:
The i is usually the square root of -1 which does not exist in the real number system.
The number given is a mixture of real and complex and is classified as complex.
The answer is C
Answer:
the answer is: C,Complex
Step-by-step explanation:
Complex Numbers
A Complex Numbers is a combination of a real number and an imaginary number in the form a + bi. The real part is a, and b is called the imaginary part.
Examples include 4 + 6i, 2 + (-5)i, (often written as 2 - 5i), 3.2 + 0i, and 0 + 2i.
Note the last two examples:
3.2 + 0i is just the real number 3.2. All real numbers are complex numbers with zero for the imaginary part.
0 + 2i is just the imaginary number 2i. All imaginary numbers are complex numbers with zero for the real part.

What is 3 3/5 divided by 2 1/4? :)
Answer:
1.6 or 8/5
Step-by-step explanation:
120 ≤ 12 k + 29 need help
The answer is [tex]k[/tex] ≥ [tex]\frac{91}{12}[/tex]
First, you must flip the equation
[tex]12k+29[/tex] ≥ [tex]120[/tex]
Then, you must subtract 29 on both sides
[tex]12k[/tex] ≥ [tex]91[/tex]
Finally, divide both sides by 12
[tex]k[/tex] ≥ [tex]\frac{91}{12}[/tex]

Quentin is planning a party. The event coordinator charges a base fee of $67 and an additional $18.50 per party guest. If Quentin has less than $400 to spend on the party, which of the following best describes all the possible numbers of guests (g) that he can invite?
Answer:
g=20
Step-by-step explanation:
Answer:g=<25
Step-by-step explanation:
John has a soup recipe that calls for two 14.5-ounce cans of chicken broth. The recipe serves 4 people. He wants to increase the recipe to serve it to a party of 28 people. If John buys chicken broth in 1-quart containers, how many containers does he need?
Answer:
6 11/32
Step-by-step explanation:
The two cans of broth used in the recipe total 2·14.5 oz = 29 oz. The number of people John wants to serve is 28/4 = 7 times the number served by one recipe. So, the amount of broth needed is ...
(29 oz)·7 = 203 oz
Each quart container of broth holds 32 oz, so John will need ...
(203 oz)/(32 oz/container) = 6 11/32 containers
John needs 6 11/32 containers of broth.
_____
If John must buy the broth, he must buy 7 containers. he will have 21/32 of a container left over after making his soup.
solve for b
thank you :)
Answer:
[tex]b = 8[/tex]
Step-by-step explanation:
First, cross multiply across the equal sign. Note that what you do to one side, you do to the other:
[tex](b+10)(2b-7)(\frac{8}{b+10}) = (\frac{4}{2b -7})(b+10)(2b-7)\\ \\(2b -7)(8) = (4)(b+10)[/tex]
Next, distribute 8 and 4 to their corresponding parenthesis:
[tex]8(2b -7) = 16b - 56\\4(b + 10) = 4b + 40[/tex]
[tex]16b - 56 = 4b + 40[/tex]
Next, isolate the variable, b. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 56 and subtract 4b from both sides:
[tex]16b (-4b) - 56 (+56) = 4b (-4b) + 40 (+56)\\16b - 4b = 40 + 56\\12b = 96[/tex]
Isolate the variable, b. Divide 12 from both sides:
[tex]12b = 96\\\frac{12b}{12} = \frac{96}{12} \\b = \frac{96}{12} \\b = 8[/tex]
[tex]b = 8[/tex] is your answer.

Solve quick le,ase
Answer:
x>-39
Step-by-step explanation:
-4x/-4=x
-4/-4=1
1-40=-39
Answer: x is greater than 9 x>9
Step-by-step explanation:
You see -4 times 9 equals to -36. And -36+plus 40 equals to -4. The question is asking you to make sure the left side is greater. So, it has to be greater than 9. for example -4 times 8 equals to -32. And -32+40 equals to 8. So your answer is X>9. I hope that helped you.

Find the sum or difference of the polynomials (x2−xy+y2) − (x2+xy+y2)
Madison is starting her own sewing business. Madison thinks she will do a better job than her competitors, so she thinks she can charge $13.05 per hour. If she knows she will only be able to work 190 hours per month (that's 47.5 hours per week), how much money will she earn each month?
Answer:
$2479.5Step-by-step explanation:
In this problem we will estimate her monthly earnings
given that she earns $13.05 per hour
and also given that she works for 190 hours in a month
then in a month, her earnings will be
=$13.05*190
=$2479.5
alternatively,
per week she works 47.5hours
in a week she will earn 13.05*47.7= $622.485
4 weeks make a month
then after one month her earning will be
$622.485*4= $2479.5
a rectangle is 3x feet long and 4feet wide.the value of the perimeter (in feet) is equal to the value of the area in square feet. find x
Answer:
x = [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
Rectangle:
Length = 3x feet
Width = 4 feet
Perimeter = 2*(length +width)
= 2* (3x + 4)
= 2*3x + 2*4
= 6x + 8
Area = length * width
= 3x * 4
= 12x
Area of rectangle = perimeter of rectangle
12x = 6x + 8 {Subtract 6x form both sides}
12x - 6x = 8
6x = 8 {Divide both sides by 6}
x = 8/6
x = [tex]\frac{4}{3}[/tex] feet

To find slope, we need two points. Once we have them, we can put them into the formula:
[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] ← this is rise/run
For 7, it's just a matter of comparing any two consecutive points.
For 8, you are given the two points.
5x+5y are like terms and can be added together to simplify to 10xy
A.True
B.False
Step-by-step explanation:
B. False
they cannot be written as 10xy but only in 5x+5y
x and y will only become together if they are multiplied
as you can see there's a plus sign
you can add them if it is in 5x+5x (or) 5y+5y but never as in 5x+5y

How do you know if a set of information shows a proportional relationship? Select ALL that apply.
Answer:
(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

Answer:
It entirely depends upon an individual.
It’s a known fact that humans need social interaction. Lack of which can affect their social behaviour and mindset. Whilst most would agree that e-learning is widely preferred by the younger generation, it is undeniably detaching them from social interactions.
When kids or students are engrossed in learning online, they’re missing out on social interactions that can open various doors of the mind, be it creative or observational skills. It’s understood that e-learning allows an individual to study far and beyond the subject and gives them an opportunity to explore multiple fields of their interest, one can’t ignore that it chains them to the system as well.
The deal-breaker in such a situation is an individual. If they demand social interaction, they would keep their digital device aside for once and would get indulge in social interaction. If they’re of another kind, they would prefer spending their days and nights just exploring and reading about new things online.
So, in my opinion, it’s quite subjective to narrow down the overall benefits and drawbacks of e-learning.
I hope I have answered your question.
