I think
Step-by-step explanation:
12.5 since it decreases 10% and the old bag had 14 cups and 10% is 1.4
If there were 30 Girls, 4 Girls played for each part.
60/ (30/100)
= 60* (100/30)
= 200
The final answer is 200~
Try 18 and then multiply the sum of 2 and 18 to 7
18. S=r^2-t^2
S+t^2=r^2
r=sqrt(S+t^2)
20. Tan 18=x/12
x=12×Tan 18
x=3.899036355
x=3.90
I hope this helps.
