Answer:

Step-by-step explanation:
In the fifth grade class,
of the girls have brown hair. Again among those of the brown-haired girls,
of them have long hair.
We are asked to find the fraction of the girls who have long brown hair in the class.
The fraction of the total students which have long brown hair will be (
) =
. (Answer)
Answer:
m = 2/3
Step-by-step explanation:
Slope is defined as the ratio rise/run.
As we move from (10, 20) to (30, 50), the run is 30 - 10, or 20, and the rise is 50 - 20, or 30. Thus, the slope of the line is m = 30/20, or 2/3.
The vertices of the triangle are the points where any pair of lines intersect.
We start by setting up the system

Using one of the two equations we can derive the correspondent y value:

So, one vertex is (1, 1)
We choose the other two pairs of lines to find the other vertices:


So, the three vertices are (1, 1), (2, 0), (-1, -3).
3 √2 3√2(2√3 + 5√2) 30 + 6√6 30 + 6√6
------------- = ----------------------------- = ------------------ = ----------------
2√3 - 5√2 (2√3 - 5√2)(2√3 + 5√2) 12 - 50 -38
-15 - 3√6
= ---------------- answer
