Simple; you want to divide 3 and 8.
3 / 8 = 0.375
And there's your answer! Remember that a fraction is just a fancy division problem! :)
0.75^2 = 0.5625.....sq rt 0.5625 = 0.75
Hello,
z=(1/√2-1/√2 i)^6=1/8*(1-i)^6=1/8*(√2∡-45°)^6=1/8*8∡-270°=1∡90°=i

Answer: 40
Step-by-step explanation:
Number of correct questions Sally got = 28 questions
Percentage of correct questions answered= 70% on the exam,
Total number of questions in the exam = Unknown
Let the total questions in the exam be represented as y.
Since Sally got 70% correctly, this will be:
70% of y = 28
70/100 × y = 28
0.7 × y = 28
0.7y = 28
Divide both side by 0.7
0.7y/0.7 = 28/0.7
y = 40
There are 40 questions in the exam.
There is a pattern of 8 after each number (b)
For 8, it's 6.2 . For 9, it's 7.0 (or 7)
