The answer is 9-11i
5+4=9
-3i+-8i=-11i
Hey there :),Good question!
If question 12=40%
Lets determine how many questions fill 20% of the progress bar
Take 12 and divide by 2 to get half of the questions
12/2=6
6 questions equal 20% progress bar
100/20= 5
Next multiply 6 and 5 to find the total number of questions:
6×5=30
The answer is 30 Total Questions are on the test
Answer:
The question
after change the mixed number to improper & using KCF will become : ![\mathbf{=\frac{7}{2}\times \frac{3}{1}}](https://tex.z-dn.net/?f=%5Cmathbf%7B%3D%5Cfrac%7B7%7D%7B2%7D%5Ctimes%20%5Cfrac%7B3%7D%7B1%7D%7D)
Option B is correct option.
Step-by-step explanation:
We need to change the mixed number to improper & use KCF to rewrite the question.
The expression is: ![3\frac{1}{2}\div\frac{1}{3}](https://tex.z-dn.net/?f=3%5Cfrac%7B1%7D%7B2%7D%5Cdiv%5Cfrac%7B1%7D%7B3%7D)
First converting mixed fraction into improper fraction
Multiply whole number with the denominator i,e (3*2=6) now add the numerator i.e (6+1) = 7/2
Solving:
![3\frac{1}{2}\div\frac{1}{3}\\=\frac{7}{2}\div\frac{1}{3}](https://tex.z-dn.net/?f=3%5Cfrac%7B1%7D%7B2%7D%5Cdiv%5Cfrac%7B1%7D%7B3%7D%5C%5C%3D%5Cfrac%7B7%7D%7B2%7D%5Cdiv%5Cfrac%7B1%7D%7B3%7D)
Using KCF
KCF stands fro Keep it, Change it, Flip it.
It is used when division sign is converted to multiplication the term (1/3) is reversed to (3/1)
So, our expression will be
![=\frac{7}{2}\times \frac{3}{1}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B7%7D%7B2%7D%5Ctimes%20%5Cfrac%7B3%7D%7B1%7D)
So, The question
after change the mixed number to improper & using KCF will become : ![\mathbf{=\frac{7}{2}\times \frac{3}{1}}](https://tex.z-dn.net/?f=%5Cmathbf%7B%3D%5Cfrac%7B7%7D%7B2%7D%5Ctimes%20%5Cfrac%7B3%7D%7B1%7D%7D)
Option B is correct option.
Answer:
p=56
Step-by-step explanation:
multiply by 7 to get it out of denominator
Answer: A & C
The dimensions of the larger cylinder are 3 times the dimensions of the smaller cylinder.
If proportional dimensional changes are made to a solid figure, then the surface area will change by the square of the scale factor of similar solids.
