Answer:
M/N=5/8 or 62.5%
Step-by-step explanation:
when turning the word problem to equation...
![\frac{x}{y} \frac{80}{100}*M=\frac{50}{100}N\\\\ \frac{80M}{100}=\frac{50N}{100}\\ then you should criss-cross\\\100(80M)=100(50N) then you divide both sides by 100)\\80M=50N\\\\\frac{80M}{80}=\frac{50N}{80}\\ M=\frac{50}{80}=\frac{5N}{8}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D%20%5Cfrac%7B80%7D%7B100%7D%2AM%3D%5Cfrac%7B50%7D%7B100%7DN%5C%5C%5C%5C%20%5Cfrac%7B80M%7D%7B100%7D%3D%5Cfrac%7B50N%7D%7B100%7D%5C%5C%20%20then%20you%20should%20criss-cross%5C%5C%5C100%2880M%29%3D100%2850N%29%20then%20you%20divide%20both%20sides%20by%20100%29%5C%5C80M%3D50N%5C%5C%5C%5C%5Cfrac%7B80M%7D%7B80%7D%3D%5Cfrac%7B50N%7D%7B80%7D%5C%5C%20%20M%3D%5Cfrac%7B50%7D%7B80%7D%3D%5Cfrac%7B5N%7D%7B8%7D)
since you have the value of M in terms of N you should substitute M by 5N/8.
if you want it as a percent just multiply 5/8 by 100%.
![BY PERCENT=\frac{5}{8}*100%=\frac{500}{8}=62.5%](https://tex.z-dn.net/?f=BY%20PERCENT%3D%5Cfrac%7B5%7D%7B8%7D%2A100%25%3D%5Cfrac%7B500%7D%7B8%7D%3D62.5%25)
=62.5%
Step-by-step explanation:
As far as I understand, they can use all 26 letters (alphabet) and all 10 digits (0, 1, ..., 9), and the password looks like this:
letter-letter-letter-letter-letter-letter-number-number (6 letters, 2 numbers).
▪︎ They can reuse the letters, so they can choose the 1st letter out of 26 possible letters, then they still can choose the 2nd letter out of 26 (it's ok if they have both A's for example, they can reuse them) and so on. So each time they can choose one letter out of 26. Thus, it's 26*26*26*26*26*26.
▪︎ The same thing with numbers. Each time they can choose one number out of 10, so it's 10*10.
▪︎ Therefore, the answer is 26*26*26*26*26*26*10*10 = 30,891,577,600. That's almost 31 billion passwords.
The domain will be x>0 because their cannot be negative people or negative cost of living per person.
Hey there! :)
-(3x)² + 3 = -6
Simplify.
-(9x²) + 3 = -6
Simplify.
-9x² + 3 = -6
Subtract 3 from both sides.
-9x² = -6 - 3
Simplify.
-9x² = -9
Divide -9 from both sides.
-9x² ÷ -9 = -9 ÷ -9
Simplify.
x² = 1
So, x = 1 OR x = -1
~Hope I helped!~
Answer:
106.8 in.
Step-by-step explanation:
The circumference of a circle:
C = 2πr
Substitute the given information into the formula.
C = 2(3.14)(17) = 106.8
