Answer:
3 miles 
Step-by-step explanation:
Slope is simply the change in position per unit rate. We could conclude that the steepness of the Applachian is the rate of change in position per unit time. Since the distance hiked on the Applachian is said to be 3 miles per hour, then we can conclude that the slope of the applachian is 3 miles 
This is the change in miles / change in time. 
Chang in miles = 3 
Change in time = 1
Slope = 3/1 
Slope = 3 
 
        
             
        
        
        
I believe your mistake is that you are trying to use the sector area formula ti find arc length when there is already a formula for it.
The formula for it is 

So first substitute the values in and then simplify!

Now simplify!
21 × 118 is 2478 so it's 

When divided ou and multiplied, this is 21.62cm!

Its only asking numbers less than zero but greater than-10 so 0 and -10 will not be included. Only numbers in bn
        
                    
             
        
        
        
A straight line is represented by a linear equation given below.
The points are given as (1, 2) and (4, 4).
Start by calculating the slope (m)

So, we have

<h3>What is the slope-intercept form of the line?</h3>
The equation in slope-intercept form is then calculated as:

So, we have:

Expand 

Take LCM

Multiply through by 3
3y=2x+4
So, the possible equations are:

Answer:
20
Step-by-step explanation:
He wil be 20 because if his brother is 10 and it says his brothers age is his age but just doubled then it would be 20 example: If bobs brother was 40 then bob would be 80
