Answer:
<h2>The answer is 13.4 units</h2>
Step-by-step explanation:
The distance between two points can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
A (10,-1) and B (-2,5)
The distance is

We have the final answer as
<h3>13.4 units to the nearest tenth</h3>
Hope this helps you
For the girls:
12:30
Simplifying it, we get:
6: 15
2: 5
For the boys:
16:40
Simplifying it, we get:
8:20
4:10
2:5
So yes, the ratios are both the same for boys and girls.
F(n)=235-(235*.3^n)+50n is your equation where * is multiplication and ^ it to the power to.
