Angle DCA is 120°. What percent of the circle's area does this section represent?

1 answer:

4 0

A circle is 360

so we're going to set up a proportion

120 x
------ = ------
360 100

then cross multiply and divide

120 times 100=12000/360=33.3333333

so the answer is C. 33

I hope I've helped!

A computer training institute has 625 students that are paying a course fee of $400. Their research shows that for every $20 red

Anastasy [175]

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.
