Thirty percent of the students in a high school face a disciplinary action of some kind before they graduate. Of those students,

MAXImum [283]

Answer:

D. 54%

Step-by-step explanation:

For simplicity, lets assume we have 100 students in high school.

30% of students face disciplinary action, therefore;

⇒ (30/100) x 100 = 30 students.

of these 30 students, 40% go to college. therefore;

⇒ (40/100) x 30 = 12 students (go to college)

Also 70% of students do not face disciplinary action, therefore;

⇒ (70/100) x 100 = 70 students.

of these 70 students. 60% go to college. therefore;

⇒ (60/100) x 70 = 42 students (go to college)

Total number of students who go to college

⇒ 12 + 42 = 54 students

% of students who go to college

⇒ 54/100 = 54%

liberstina [14]

Answer:

See below in exact form

2.42, -12.42 to the nearest hundredth.

Step-by-step explanation:

x^2 + 10x - 13 = 17

(x + 5)^2 - 25 - 13 = 17

(x + 5)^2 = 17 + 38 = 55

x + 5 = +/- √55

x = -5 + √55, -5 - √55.

Nady [450]

Answer:

The percentage increase without baggage fee=25%

The percentage increase with baggage fee=41.66%

Step-by-step explanation:

Given the cost of the airline ticket two weeks ago is $300 and The present airline ticket is $375

We know that when a quantity increases from x to y then The percentage increase is equal to $\frac{y-x}{x} *100$

Here the percentage increase = $\frac{375-300}{300} *100$ =25%

Now the airline charges an extra $50 baggage fee which means teh present value of the airline ticket is $375+$50=$425

the percentage increase = $\frac{425-300}{300} *100$ =41.66%
