Each ruler would cost about 9 cents 
        
             
        
        
        
Answer:
Step-by-step explanation:
time to cross will be the distance divided by the velocity in that direction.
a) t = d/v = 45/2.75 = 16.363636... 16.4 s 
In the same time that the otter is swimming cross stream, the stream is also moving perpendicularly at its own pace.
b) d = vt = 2.5(16.36) = 40.9090... 40.9 m
As velocity is a vector, An observer on the bank would see the velocity as the vector addition of the cross stream and down stream velocities
c) v = √(2.75² + 2.5²) = 3.716517... 3.72 m/s  magnitude
   θ = arctan2.5/2.75 = 42.2736... 42.3° downstream of a line straight across

Answer:I think your Answer would be x=14 but I am not sure.
Step-by-step explanation:
2log 10 (x+86)=4
Determine the defined 
2log 10 (x+86)=4,x >-86
Divide both sides by 2 
log 10 (x+86)=2
Solve by converting the logarithm into exponential form 
x+86=10 2 
Evaluate the power 
x+86=100
Move constant to the right 
x=100-86
Subtract the numbers 
x=14,x>-86
Check if the solution is in the defined range 
SOLUTION
X=14
