Answer:
Hey there!
Think of 45000 being split to 9 pieces.
Each piece would be 5000 dollars.
Thus, the ratio would be 20000 to 25000
Hope this helps :)
Answer:
Everyone would pay 116.66, but one of them would have to pay one cent extra!
Step-by-step explanation:
Answer: 0.5
1) convert to I proper fraction
2) divide the fraction
1.
If no changes are made, the school has a revenue of :
625*400$/student=250,000$
2.
Assume that the school decides to reduce n*20$.
This means that there will be an increase of 50n students.
Thus there are 625 + 50n students, each paying 400-20n dollars.
The revenue is:
(625 + 50n)*(400-20n)=12.5(50+n)*20(20-n)=250(n+50)(20-n)
3.
check the options that we have,
a fee of $380 means that n=1, thus
250(n+50)(20-n)=250(1+50)(20-1)=242,250 ($)
a fee of $320 means that n=4, thus
250(n+50)(20-n)=250(4+50)(20-4)=216,000 ($)
the other options cannot be considered since neither 400-275, nor 400-325 are multiples of 20.
Conclusion, neither of the possible choices should be applied, since they will reduce the revenue.
Step-by-step explanation:
okay
I think you should use the method of tan 30
and then find x by using pythagorean theorem
