5π/12
75∘⋅π/180∘=5π/12
Therefore the answer not rounded is 1.309 radians
Answer:
the solution to the equations is :-
(4,3)
Step-by-step explanation:
here's the solution :-
=》x + 2y = 10
=》x = 10 - 2y
now, plugging the value of x in other equation :-
=》9x - 2y = 30
=》9 × (10 - 2y) - 2y = 30
=》90 - 18y -2y = 30
=》-20y = 30 - 90
=》y = -60 ÷ -20
=》y = 3
now, plugging the value of y in first equation,
=》x = 10 - 2y
=》x = 10 - (2×3)
=》x = 10 - 6
=》x = 4
so, the solution of the system is (4,3)
Answer:

Step-by-step explanation:
y = mx + b
Where M is the slope and b is the Y-intercept
1st drop- 10ft comes back up 5ft
2nd drop-5ft comes back up 2.5ft
3rd drop-2.5ft comes back up 1.25 ft
4th drop-1.25ft comes back up .625ft
(10+5) + (5+2.5) + (2.5+1.25) + (1.25) = 27.5ft
