C: 15,938 + 427 is 4 times as large as (15,938 + 427) /4
Hey!
-------------------------------------------------
Solution:
The ratio is FEMALES to MALES.
So its 18/16, 18:16, or 18 to 16.
~Now we need to simplify.
18:16 → 18/2:16/2 → 9:8
*Note* When you have a ratio you need to know which comes first. If you put males to females that incorrect. It has to be correct according to the question.

Answer:30 feet.
Step-by-step explanation: 2 doubled is four and in the bigger triangle it says 5. Therefore 12 doubled and a bit more is 30
.10 I hope that that helps you :)
Table:
x y
-3 0.5
-2 1
-1 2.5
0 5
1 8.5
Now, y = ax^2 + bx + c
Start replacing x = 0 and y = 5
5 = a(0) + b(0) + c => c = 5.
Now, replace any other two pair of data:
(-2, 1) => -1 = a(-2)^2 + b(-2)
-1 = 4a - 2b
(1, 8.5) => 8.5 = a(1)^2 + b(1)
8.5 = a + b
Solve the system
4a - 2b = - 1
a + b = 8.5
=>
4a - 2b = - 1
2a + 2b = 17
-------------------------
6a = 16
=> a = 16 / 6 = 8/3
b = 8.5 - a = 17/2 - 8/3 = 35/6
=> y = (8/3)x^2 + (35/6)x + 5 <--------- answer
