How many ways can 6 people sit on a bench if 3 of them have to sit side by side

Mathematics
1 answer:
pickupchik [31]3 years ago
4 0

Answer:

144 ways

Step-by-step explanation:

Let's think of the 3 persons sitting together as "one". So essentially we have 3 + "1" = "4" persons to arrange.

THey can be arranged in 4! ways, which is:

4! = 4 * 3 * 2 * 1 = 24 ways

Now, the 3 persons themselves can be arranged in 3! ways, which is:

3! = 3 * 2 * 1 = 6 ways

Total ways = 4! * 3! = 24 * 6 = 144 ways

after elsa backed muffins, her brother ate 4 of them, he ate 2/5 of all the muffins, how many muffins did elsa bake?
kondor19780726 [428]
If he ate 4 of them, but it means he ate 2/5 muffins, 
4 muffins = 2/5 muffins
You substitute x muffins for how much muffins she baked in all -
2/5* x muffins = 4
2/5 multiply by 2/5 to cross it out. Do the same to the other side. 
x= 4 *5/2
x = 10 muffins
So there were 10 muffins in all
