Answer:
First
Step-by-step explanation:
The first person in the line will always have an odd position, not an even one. They will be the only one left.
He has dropped 10 points
Explanation:
Since he dropped 2 points EACH day for 5 days, we do 2+2+2+2, or 2x5 = 10
550 ml is the original amount in addition to the 18% that was given free
We can write this as
550 = 100% + 18% = 118%
550 = 118%
The first step to working this out is to work out what 1% of the drink is equivalent to
To get from 118% to 1%, we must divide by 118
We do exactly the same to the drink
550/118 = 4.661ml
We also know that 18% was given free
4.661 x 18 = 83.898ml Free
83.9ml free
You need to be note specific
((4 3/8)/(3/4)) x 4/7
(4 3/8)/(3/4 x 4/7)
In the future, would you please post just one or two problems at a time. Be fair to others who also want help.
#5: <span>(-4)^8/(-4)^4 can be expressed more clearly as (-4)^8
---------
(-4^4)
and this can be reduced to (-4)^4 by subtracting the exponent 4 from the
exponent 8.
furthermore, because of the even exponent, (-4)^4 can be written as 4^4.
Note that 4^4 = (4^2)^2 = 16^2 = 256 (answer)</span>
