Answer:
In total, 
permutations of three items can be selected from a group of six distinct elements.
In particular, there are 
ways to order three distinct items.
.
Step-by-step explanation:
The formula 
gives the number of ways to select and order 
items from a group of 
distinct elements.
To select and order three items from a group six distinct elements, let 
and 
. Apply the formula:
.
In other words, there are unique ways to select and order three items (select a permutation of three items) from a group of six distinct elements.
Consider: what's the number of ways to order three distinct items? That's the same as asking: how many ways are there to select and order three items from a group of three distinct elements? Let 
and . Apply the formula for permutation:
.
To find the permutations, start by selecting one element as the first of the list. A tree diagram might be helpful. Refer to the attachment for an example.
Answer:
The simplest way to teach middle school math scale drawings is to use real pictures to relate to each other to explain the concept. For example, scaling a red ball of 1" to a ball of 2" and so on. This will show how the ball increases by size by adding 1" each time.
So first find the distance from the bottom of the lumber to the wood
40^2= 36^2+X^2
X=304^1/2. Or the sqaure root of 304
The you use the sin equation
Sin90*\40= sin(unknown angle)/304^1/2
Sinx(x) = ((304^1/2)xsin(90))/40
X=arcsin((304^1/2)xsin(90))/40
So you start with
V = <span>πr^2h
</span>you divide both sides by <span>πr^2
(v/</span><span>πr^2) = h</span>
