Answer:
P43=4!(4–3)!=241=24
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
Multiply the total land he owns by the land that is fenced. So he has 8/15 acres of land fenced.
Therefore the solution is 8/15 acres.
Answer:
Option (1)
Step-by-step explanation:
Minus notation of the elevations from the sea level represents the distance below the sea level and positive notation represents the elevations above the sea level.
+7 → 7 meters above the sea level
-3 → 3 meters below the sea level
→ 0.5 meters above the sea level
-0.8 → 0.8 meters below the sea level
+0.8 → 0.8 meters above the sea level
→ 0.1 meters below the sea level
-2 → 2 meters below the sea level
Therefore, +7 meters above the sea level will be the farthest point from the sea level.
Option (1) will be the answer.
It would take 19.31 full containers to fill the fish tank.
There is 1000 ml in a L making it 5000 ml needed to fill the tank.
Divide the 5000 ml by 259 ml to get your answer.
the simplified expression is:
6s + 9
