11 would be my best guess, kinda confusing question. I hope I helped!
If 5 cleaners took 4 hours and 30 min. to clean the whole rooms in a hotel and there's only 3 cleaners, it would take them 6 hours and 30 min. why? because 5 cleaners = 4 hours and 30 min. 4 cleaners = 5 hours ad 30 min. 3 cleaners = 6 hours and 30 min. Anyway so, if they were paid 8.20 for each hour you would multuply that so 8.20x6.5 = ?? and then you divide the answer to 3 and thats your answer
Answer:
What is the example of the secret message
Step-by-step explanation:
To do this we have to do 7 divided by 2/3
The first step to dividing fractions is to turn it into a mutipuacation sentence
7x2/3
Now we want to flip the second fraction over or make it a reciprocal
Our new equation is
7x 3/2 which is equal to 21/2
There are two ways. You may simplify it to 10 1/2 or just leave it as it is
hope this helped!! If you have questions, feel free to ask
Answer:
Step-by-step explanation:
This is permutation question
<u>The formula for it: </u>
- N = b!/(b-s)!, where N- number of ways, b- number of books, s- number of slots
<u>Finding the answer:</u>
- N = 7!/(7-5)! = 7!/2! = 7*6*5*4*3 = 2520
