Answer:
C
Step-by-step explanation:
Given the logarithmic equation
First, notice that
So, there is no possible solutions, all possible solutions will be extraneous.

Answer:
i have made it in above picture
hope it helps
Volume of cone: pi * r^2 * h/3
Given volume, height
942in^3 = 3.14 * r^2 * 9/3
942in^2 = r^2 * 9.42
Divide by 9.42
r^2 = 100, r = -10, 10
Cannot be negative so...
Solution: radius is 10 in.
Let x = the numbers of girls
thus
the numbers of boys = 2x
x + 2x = 27
3x = 27
x = 9
2x = 2 . 9 =18
girls = 9 & boys = 18
