Answer:
I got 204.82 the first time I did this one too. I tried it again rounding pi to 3.14 and got 204.78, which means your answer is a little off due to rounding different, so go with 204.78. Basically, you did it right :)
Step-by-step explanation:
P=12T
Q=66T
-----------
Toys added to each bag:
P=12T+nT
Q=66T+nT
Therefore, 66T+nT=3(12T+nT)
------------
66T+nT=36T+3nT
T(66+n)=T(36+3n)
66+n=36+3n
3n-n=66-36
2n=30
Therefore, n=30/2=15
-------------
*She added 15 toys to each bag.
1290 girls
If number of boys is 4/9 then number of girls must be 5/9 (of course this is assuming there are no non-binary people). Then just multiple 5/9 * 2322 and you get 1290 girls
Weight=8.15 ounces
silver=84%of the total weight
silver=(84/100)×8.15 ounces
silver= 0.84×8.15 ounces
silver=7.5795 ounces
silver=7.580 ounces (rounded to nearest thousandth)
Common denominators of 9 and 3 are 9. 27
