Answer: The answer is the first one d= 1/50w.
Step-by-step explanation: 3/5 divided by 30 is 1/50 as a fraction. This is the unit rate. 1/50 milligrams per pound. Hope this helps!:))
There are three answers and they are: choice 2, choice 3, choice 5
======================================================
Further Explanation:
Choice 1 is false because the intersection of the altitudes of a triangle leads to the orthocenter.
----
Choice 2 is true because the three medians of any triangle always intersect at the centroid. A median is a line that goes from one vertex to the midpoint of the opposite side. In this case, we go from point E to the midpoint of side CD. The midpoint of CD is found by bisecting segment CD (see choice 5)
----
Choice 3 is true. This is effectively the same as choice 5 below. The "perpendicular" aspect does not matter.
----
Choice 4 is false. Following the steps mentioned here will create an altitude line (see choice 1)
----
Choice 5 is true. To bisect something is to cut it in half. Let's say that point F is the midpoint of line segment CD. This means that line segment EF is one of the three medians of triangle CDE.

edit update: I changed choice 3 from false to true
Answer: A
Explanation: multiply 128 by .85
Answer:
Interest rate ≈ 3.48%
Step-by-step explanation:
Using the concept of probability and the arrangements formula, there is a
0.002 = 0.2% probability that the first 8 people in line are teachers.
----------------------------------
- A probability is the <u>number of desired outcomes divided by the number of total outcomes.</u>
- The order in which they are positioned is important, and all people will be positioned, and thus, the arrangements formula is used to find the number of outcomes.
The number of possible arrangements from a set of n elements is given by:

----------------------------------
The desired outcomes are:
- First 8 people are teachers, in <u>8! possible ways.</u>
- Last 4 are students, in <u>4! possible ways.</u>
Thus, 
----------------------------------
For the total outcomes, <u>number of arrangements of 12 people</u>, thus:

The probability is:

0.002 = 0.2% probability that the first 8 people in line are teachers.
