Answer:
The train can be made up in a total of 
ways
Step-by-step explanation:
FIrst, lets assume that all cars are distinct. If that is the case, then, since we have a total of 8 cars, we have
- 8 possibilities for the first car
- 7 possibilities for the second car
- 6 possibilities for the third car
and so on.
So we have a total of 8! = 8*7*6*...*3*2*1 possibilities to make a train.
Now lets take into account that 5 of the cars are identical within each other. Then we could make a permutation of those 5 cars and we wouldnt notice. Hence, the order of the 5 cars of second-class doesnt matter and as a result, we should divide 8! by the total of possible permutations of the 5 second class cars, that it, 5!
We also need to divide the result by 2! = 2, because which first class car came first doesnt matter either. Therefore, the train can be made up in a total of ways.
Answer:
Step-by-step explanation:
Perimeter of a shape is the total distance around it.
The formula for determining the perimeter of a circle is
Perimeter = 2πr
Where
r represents radius of the circle.
π is a constant whose value is 3.14
The given circle has a radius of
225 ft. The perimeter would be
2 × 3.14 × 225 = 1413 ft
Therefore, the perimeter of the circular path of the base ball field would be
40/100 × 1413 = 0.4 × 1413 = 565.2 ft
The perimeter of the base ball field would be
565.2 + 300 + 300 = 1165.2 ft
Time = distance/speed
Time it will take you to run around the baseball field is
1165.2/9 = 129.5 seconds
If its talking about the temperature decreased it would be -11 but it's asking for an integer
What is ttm mean? And what do you mean by points?
Triangle,quadrilateral,pentagon,hexagon,octagon,decagon.
Triangle quadrilateral octagon - regular
rest are not. Someone might need to check me if im right about regular and irregular :) Hope I helped
