Answer:
14m-1g
Step-by-step explanation:
add 11 and 3 because they both share the variable M and than do 5-6 because they both share the variable G
Answer:
1) The length of
is 20.
2) The length of
is 17.
Step-by-step explanation:
1) If
and
, then we can use the following proportionality ratio:
(1)
Where
is the length of segment
.
If
, then the value of
is:
![2 = \frac{32-x}{26-x}](https://tex.z-dn.net/?f=2%20%3D%20%5Cfrac%7B32-x%7D%7B26-x%7D)
![52 - 2\cdot x = 32 - x](https://tex.z-dn.net/?f=52%20-%202%5Ccdot%20x%20%3D%2032%20-%20x)
![20 = x](https://tex.z-dn.net/?f=20%20%3D%20x)
The length of
is 20.
2) If
and
, then we can use the following proportionality ratio:
(2)
Where
is the length of segment
.
If
, then the value of
is:
![2 = \frac{x-7}{5}](https://tex.z-dn.net/?f=2%20%3D%20%5Cfrac%7Bx-7%7D%7B5%7D)
![10 = x-7](https://tex.z-dn.net/?f=10%20%3D%20x-7)
![x = 17](https://tex.z-dn.net/?f=x%20%3D%2017)
The length of
is 17.
Answer:
P43=4!(4–3)!=241=24 24 possible choices
Step-by-step explanation:
There are four choices you can make for the lead reindeer. For each possible choice, there are then three remaining you can choose to fly second, making 4×3=12 choices for the lead pair. For each possible choice there are two remaining reindeer to take up the back position, making 12×2=24 choices for the team of three.
This type of problem is called a permutation problem, and we write Pnr for the number of ways of choosing r items from n possibilities when the order of the items matters. In this case we are choosing 3 reindeer from 4 possibilities, and the order they appear in the flying line does matter, so the answer we want is P43. The general formula is Pnr=n!(n−r)!. For the answer we are looking for we therefore have:
P43=4!(4–3)!=241=24
