Answer:
separate and square both the top and bottom
the square of square root three is just 3 and the square of 3 (the bottom of the fraction) is 9
so now you have 3(i^2) /9
you can simplify this by three and then i^2 is -1
you now have -1/3 and thats the final answer
Answer:
72
Step-by-step explanation:
there are 12 inches per foot, so if five feet is equal to 60 inches then just add 12 and you get 72. 6 feet would be equal to 72 inches
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.
