line a has a slope of 5/6 line b is perpendicular to a what is the slope of b?
Answer:
slope is -6/5
Step-by-step explanation:
A line that is perpendicular to the other the slope will be flipped and minus itself. So if the slope is positive you flip it and make it negative. But if the slope is negative you have to flip it and make it positive because a negative times a negative equals positive.

6. A theater has 490 seats. Seats sell for $25 on the floor, $20 in the mezzanine, and
$15 in the balcony. The number of seats on the floor equals the total number of
seats in the mezzanine and balcony. Suppose the theater takes in $10,520 from a
sold-out event. Which system of equations represents this situation?
Answer:
There are 245 seats on the floor, 101 seats on the balcony and 144 seats in the mezzanine
Step-by-step explanation:
first equation: all sections added together equaling total number of seats. second equation: price of each type of seat multiplied by number of each seat, added together equals total sales. third equation: relates floor seats to addition of other two types
2
subtract f from both sides of third equation
3
first equation: add first equation from first step and equation from previous step
second equation: add second equation from first step and 25 times equation from previous step
4
subtract 40 times second equation in previous step from first.
5
plug m-value into first equation from third step
6
plug m and b values into first equation from first step
The equation that can be used to represent the information will be b + f + m = 490 and 15b + 25f + 20m = 10520.
Let the floor be represented by f.
Let the mezzanine be represented by m.
Let the balcony be represented by b.
Therefore, based on the information given, the equation to solve the question will be:
b + f + m = 490
15b + 25f + 20m = 10520
Therefore, the equation will be b + f + m = 490; 15b + 25f + 20m = 10520.

There are three clubs at Redwood High School: Debate, Student council, and Key club. There are 1000 students in the school. And everyone is in at least one club.
• The total number of students in the debate club is 310
• The total number of students in the Student council is 650
• The total number who are in debate and student council is 170
• The total number of students who are in both debate and the key club are 150
• The total number of students who are in both student council and the key club is 180
• There are 50 students who are in all three clubs How many students are in the key club?
Answer:
The number of students in the key club is 490
Step-by-step explanation:
The given parameters are;
The number of student in the school = 1000
The total number of student in the debate club = 310
The total number of student in the student council = 650
The total number of student who are in debate and student council = 170
The total number of student who are in both debate and the key club = 150
The total number of student who are in both student council and the key club = 180
The number of students who are in all three clubs = 50
Therefore, we have;
Let A represent the number of students in the debate club
Let B represent the number of students in the student council
Let C represent the number of students in the key club
We have;
n(A∪B∪C) = n(A) + n(B) + n(C) - n(A∩B) - n(B∩C) - n(C∩A) + n(A∩B∩C)
Where;
n(A∪B∪C) = 1000
n(A) = 310
n(B) = 650
n(A∩B) = 170
n(B∩C) = 180
n(C∩A) = 150
n(A∩B∩C) = 50
Therefore;
n(C) = n(A∪B∪C) - (n(A) + n(B) - n(A∩B) - n(B∩C) - n(C∩A) + n(A∩B∩C))
Substituting the values gives;
n(C) = 1000 - (310 + 650 - 170 - 180 - 150 + 50) = 490
The number of students in the key club, n(C) = 490.

The following quadratic function describes a launched Air Force missiles height over time is h(t)=-t^2+6t.
a. Why is it important to know the zeros of the function? what do the zeros tell us?
b.How long was the missile in flight for?
c. what was the maximum height reached by the missile?
d. The early warning system alarmed when the missile was descending and reached the height of 8 km. how much time is there before impact?
Answer:
See below.
Step-by-step explanation:
a) The zeros tell us when the missiles will be at ground level after being launched.
b) h(t) = 0 = -t^2+6t = t(6-t)
The missile was in flight for 6 units minutes.
c) h'(t) = -2t+6 = 0 --> t = 3
h(3) = 9
d) 8 = -t^2+6t
t^2-6t+8 = 0
(t-2)(t-4)=0
The missile is descending at a height of 8 km at 4 minutes.
It lands at 6 minutes. So, it will impact 2 minutes after the early warning alarm.
