Answer:
r=1
Step-by-step explanation:
-7.61 - 4.3r = -8.1r - 3.81
(bring like terms to one side)
-4.3 r = -8.1r -3.81 + 7.61
-4.3r + 8.1 r =-3.81 + 7.61
(consolodate)
3.8r = 3.8
(divide right by # of r)
r = 3.8/3.8
r = 1
Answer:
168pi cm2
Explanation:
SA = 2pi(r^2) + 2pi(r)h
diameter is 8 cm so radius is 4 cm
SA = 2pi(4^2) + 2pi(4)17
SA = 32pi + 136pi
SA = 168pi cm2
Revenue of Movie A on first weekend = $ 142.44 million
According to the given statement, revenue of movie A was $4.14 million more than the revenue of movie B in their first weekends.
So, we can write:
Revenue of movie A = Revenue of movie B + $4.14 million
Revenue of movie B = 142.44 million - 4.14 million = $ 138.30 million.
Thus movie B take in $138.30 million on its opening weekend.
The slope would be -2 because the graph is going down and from the y-intercept (0-2), it is going 2 units down and 1 unit right.
