I think 8 or 7 because its -3 so +3 to the 5 minutes or 2 since it is a sprinkler hope i help
Answer:
80
Step-by-step explanation:
A certain company employs 6 senior officers and 4 junior officers. If a committee is to be created that is made up of 3 sr officers and 1 jr officer, how many different committees are possible?
8
24
58
80*
210
I initially got this one wrong, but after I saw the answer which is 80, I was able to solve it. But im not sure if this is the proper way of solving it, or if someone can suggest a more efficient way of solving it?
This is what I did, which was wrong:
Sr Officers + Jr Officers
(6!/3! 3! = 20) + (4!/3! = 4) = 24
It seems like the correct answer is:
Sr Officers X Jr Officers
(6!/3! 3! = 20) x (4!/3! = 4) = 80
If this is the most efficient way of solving, when do you know when to add them as opposed to multiplying them in this case?
Answer:
x=2
Step-by-step explanation:
4x+1=2x+5
-2x -2x
2x+1=5
-1 -1
2x=4
2x/2
4/2
x= 2
sorry I didn't explain better but here
If Fraction has denominators such as 10, 100 or 1000 it would be easy to convert it into decimal. Like this:
6
------- - Fraction.
100
Now, Write down the number six and add zeros to it. If the denominator has 2 zeros in it then the there should be two decimal numbers. Answer for the above fraction would be: 0.06.
If a fraction does not have denominators such as 10, 100 or 1000, then do the following:
6
------
25
The above fraction's denominator is not 10, 100 or 100. So, multiply the numerator and the denominator with a number that would give you the denominator as 10, 100 or 1000.
6 × 4 = 24
----- ---- -------
25 × 4 = 100
Now, you can convert it as 0.24
If a fraction has a denominator that cannot be converted into 10, 100 or 1000, then directly divide and write the decimal.
Hope it helped you, Sophia46!!
