Answer:
61
Step-by-step explanation:
If there are 6 coins on each page, then the number of pages for 600 coins is ...
(600 coins)/(6 coins/page) = 100 pages
__
If 39% are empty, then 100% -39% = 61% are filled.
The number of filled pages is ...
61% × 100 = 61/100 × 100 = 61 . . . . pages filled
_____
<em>Comment about percent</em>
You can think of the percent symbol (%) and "per 100" (/100) as being interchangeable. 61% = 61/100
("Cent" is used to signify one of 100 parts. A cent is 1/100 of a dollar, for example. In land area, a cent is 1/100 of an acre. Then, "percent" can be thought of as "per cent" or "per 100 parts".)
Answer:
The 1918 influenza pandemic was the most severe pandemic in recent history. It was caused by an H1N1 virus with genes of avian origin. Although there is not universal consensus regarding where the virus originated, it spread worldwide during 1918-1919. In the United States, it was first identified in military personnel in spring 1918. It is estimated that about 500 million people or one-third of the world’s population became infected with this virus. The number of deaths was estimated to be at least 50 million worldwide with about 675,000 occurring in the United States.
dunno if this helps or not i hope it does!
Step-by-step explanation:
Multiply the second equation by -3 in order to cancel out U
3u+z=15
-3(u+2z)=10
3u+z=15
-3u-6z=-30. Then u subtract those two equations
-5z=-15
Z=3
To solve for u, plug in the z in one of the equation (doesn’t matter which one)
3u+3=15
3u=12
U=4
Ur answer is
U=4. Z=3
