The ratio in which girls and children are born is 2 to 5, and 35 are born. How many girls are born?
2 answers:
The ratio in which girls and children are born is 2 to 5, then the number of girls born is 10
<u>Solution:</u>
Given that the ratio of girls and children is = 2 : 5
Let the number of girls born be "2x" and number of children born be "5x"
Given that 35 are born, So total born = 35
Hence we get,
2x + 5x = 35
7x = 35
x = 5
So number of girls born is:
Hence number of girls born is 10

Answer:
Step-by-step explanation:
Given equation can be re written as
............(i)
Now it is given that y(π/2) = 2e
Applying value in (i) we get
ln(2e) = sin(π/2) + c
=> ln(2) + ln(e) = 1+c
=> ln(2) + 1 = 1 + c
=> c = ln(2)
Thus equation (i) becomes
ln(y) = sin(x) + ln(2)
ln(y) - ln(2) = sin(x)
ln(y/2) = sin(x)
