Answer:
The total amount of students in the class would be 30. The total amount of girls would be 12.
Step-by-step explanation:
60% * x = 18
(60/100) * x = 18
6x/10 = 186x = 18 * 10
6x = 180x = 180/6 = 30
The total number of students in the class is 30.
Number of girls in the class = 30 - 18 = 12
So there are 12 girls in the class.
Answer:
Step-by-step explanation:
2√5*√19=2√95≈19.494≈19.49≈19.5
if you want exact then 2√95
if three decimal places then 19.494,if two decimal places then 19.49 ,if one decimal place then 19.5
The answer is f^-1(x)=8/3+x/3
