Weight is another term for the force from mass multiplied by acceleration due to gravity, the equation being expressed as 

, being force, mass, and acceleration respectively.
We already have 2 parts of the equation,
 
 Acceleration due to gravity on the planet is 

Plug it into the equation 


 x 

Weight or force from gravity is 60N.
 
        
        
        
Tan(angle) = opposite/adjacent
tan(x) = 90/51
x = arctan(90/51)
x = 60.461217740442
which rounds to 60 when rounding to the nearest whole number
Answer: 60
        
             
        
        
        
The slope is negative, so the slope is negative. Using the rise over run formula, the slope of the line should be -1.
        
             
        
        
        
Given :
Natalie is going mountain biking. She can buy a bike for $250 or she can rent a bike for $30 an hour.
In both cases, she must also rent a helmet for $5 an hour.
To Find :
Which inequality shows the number of hours Natalie must bike for the cost of buying a bike to be less than renting a bike.
Solution :
Let, after t hours total money required is ( if she rent bike ).
T = 30t.
Money required to purchase bike , M = $250.
For cost of buying a bike to be less than renting a bike :
 
 
Hence, this is the required solution.
