Answer:
t < 4
Step-by-step explanation:
Reservation fee = $38
Additional fee per hour = $6.80
The history club wants to spend less than $65.20 on renting the meeting room.
t = number of hours the meeting room is rented
The inequality is
38 + 6.80t < 65.20
6.80t < 65.20 - 38
6.80t < 27.20
t < 27.20 / 6.80
t < 4
Therefore, number of hours the meeting room is rented should be less than 4 hours
Answer:
<h2>a)
x + y = -2</h2><h2>
b) x - y = -8</h2><h2>
c) 3x - 5y = -30</h2><h2>
d) 5x + 3y = -16</h2>
Step-by-step explanation:
Equation of line with slope m and passing through (x₁,y₁) is given by
y - y₁ = m ( x -x₁)
(x₁,y₁) = (−5,3)
a) Parallel to x = −1
Slope , m = -1
y - y₁ = m ( x -x₁)
y - 3 = -1 ( x -(-5))
y -3 = -x - 5
x + y = -2
b) Perpendicular to x = −1.
Slope of line x Slope of perpendicular line = -1
Slope of line x -1 = -1
Slope , m = 1
y - y₁ = m ( x -x₁)
y - 3 = 1 ( x -(-5))
y -3 = x + 5
x - y = -8
c) Parallel to y = 3 / 5 x + 2
Slope , m = 3/5
3x - 5y = -30
d) Perpendicular to y = 3 / 5 x + 2
Slope of line x Slope of perpendicular line = -1
Slope of line x 3/5 = -1
Slope , m = -5/3
5x + 3y = -16
The correct is one is; A cylinder is like a stack of circles. The volume of the cylinder would be the area of the circle multiplied by the height of the cylinder. The height of the cylinder represents how many circles are in the stack. Therefore, we get the formula πr²h, where πr² represents the area of the circle and h the height of the circle.
