0.27 repeating as a fraction in simplest form is 3/11
The reflection over the y-axis has a rule:
From the diagram you can see that point W has coordinates (-7,2). Then using the rule given above, you can find the coordinates of point W':
Answer: (7,2).
Answer:
Maximum distance = 94.6 million miles
Minimum distance = 91.4 million miles
Step-by-step explanation:
The mean distance of the Earth from the sun is 93 million miles.
The distance varies by 1.6 million miles.
The maximum distance of the Earth from the sun is 93 + 1.6 = 94.6 million miles
The minimum distance of the Earth from the sun is 93 - 1.6 = 91.4 million miles.
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.
