Answer: H = 1
Step-by-step explanation:
Let x + 15 = total penguins
15/ (x +15) = .30
15 = .30x + 4.5
.30x = 10.5
x = 35
Total penguins = 15 + 35 = 50
Double Check
15 / 50 * 100 = 30% Correct!!!
The coordinates of the point that is one-half the distance between A(-1,-2) and B(6,12) is (2.5,5)
What is the midpoint?
The mid-point lies midway between the two ends. Its x value lies in the middle of the other two x values. Its y value lies in the middle of the other two y values.
Given, 

Let M is a midpoint of AB, then

The midpoint of point AB is M(2.5,5)
Therefore, the coordinates of the point which is one-half the distance between A(-1,-2) and B(6,12) is M(2.5,5).

C - 2c = 2c - 2c - 4
c - 2c = -4
-c = -4
c = 4
Answer:
c^2=a^2+b^2
c^2=6^2+8^2
c^2=36+64
c=10
