Answer:
12 ways
Step-by-step explanation:
Normally there are 4 species of deer in the reindeer, which normally could have been arranged in 4! ways = 24 ways
Now considering the restriction that Prancer and Lancer are put apart
The number of arrangement when they are apart = Total number of ways - number of ways when they are together
Note: If they are put together, the two are seen as one which makes the arrangement to be 3!, but also note that either of them can be at the front or back.
Therefore, the number of arrangement when Prancer and Lancer are put together = 2(3!) = 2(3*2*1) = 12 ways
The number of arrangement when they are put apart = 24 - 12 = 12 ways
Answer:
900° and 1260°
Step-by-step explanation:
The sum of the interior angles of a polygon is calculated as
sum = 180° (n - 2) ← n is the number of sides
(2)
Here n = 7 , then
sum = 180° × 5 = 900°
(3)
Here n = 9 , then
sum = 180° × 7 = 1260°
Bike is rented for $9/hour and scooter can be rented for $10/hour. So for the bike it would be 9b (9xb) and the scooter is 10s (10xs) for the total cost of both of them the answer is 9b+10s
Answer:
think its 1.10? tbh thats probably wrong
