Answer:
17:14 or 17 to 14
Step-by-step explanation:
since you know there are 14 girls, subtract 14 from 31 and then you'll get 17. since its asking for a ratio of boys to girls not girls to boys, you put boys first, then girls. so your answer will be 17:14

OK. Let's build this thing brick by brick,
one step at a time:
The number. . . . . . . . . . . . . . . . . . . . . . . N
==> Three times the number . . . . . . . . 3N
6 times the number. . . . . . . . . . . . . . . . 6N
==> 28 more than 6 times the number . 6N + 28
You said the three times the number is the same
as 28 more than 6 times the number.
So I can write
3N = 6N + 28
That's the equation.
Subtract 3N from each side: 0 = 3N + 28
Now subtract 28 from each side: -28 = 3N
Now divide each side by 3 : N = - 28/3 .
That number is kind of weird, but it's the ONLY number
that behaves according to the description in the question.
Three times the number . . . . . -28
6 times the number . . . . . . . . . -56
-28 is 28 more than -56. yay!
Answer:
38.21 in
Step-by-step explanation:
Given data
C= 120meters
We also know that circumference
C=2πr
Substitute
120=2*3.142*r
120= 6.28r
r= 120/6.28
r= 19.10 m
Hence the diamter D
D= r*2
D= 38.21 in
