What is the missing length?
TEA [102]
Answer:  13.722 km ;  or, write as:  13  13/18 km .
___________________________________________________
Explanation:
___________________________________________________
Area = Length * width ; 
___________________________________________________
or, write as:  A = L * w ;
________________________

Given: A = 247 km² ; 
           
          L = 18 km ; 
 
          w = "y" ; 
________________________
 Find:  "y"
______________________________
  A = L * w ; 
______________________________
Plug in our values:
______________________________
  247 km² = 18 km * "y" ;  solve for "y" (in units of "km") ;

_____________________________
        18 y = 247 ; 
___________________________________________________________
Divide each side of the equation by "18"; to isolate "y" on one side of the equation; and to solve for "y" :
___________________________________________________________
        18 y / 18 = 247 / 18 ;
_____________________________________________
  to get:
_____________________________________________
              y = 13.7222222222222222...... km ;  round to: 13.722 km

                   or;  y = 13  13/18 km .

Find the slope and y intercept of the graph of the graph of each equation.
AleksandrR [38]
Solve each equation for y and then the slope is m and y-intercept is b as in:
y = mx+b

So, if you do that, you'll get (remember, this is <em>after</em> solving for y):
1. m = -6, b = -2
2. m = 5, b = -1
3. m = -5/3, b = 5
4. m = 0, b = -1/4
5. m = -1, b = -3
6. m = 3, b = -4
7. m = 1/2, b = -5/2
8. m = 7/2, b = 1

Hope this helps.

Mariulka [41]

Answer: 30.1

Step-by-step explanation:

Cups of raisins mixed= 10.33

Cups of pretzels mixed= 12.25

Cups of chocolate mixed= 7.50

When each ingredients is rounded to the nearest tenths, it will be:

Cups of raisins mixed= 10.3

Cups of pretzels mixed= 12.3

Cups of chocolate mixed= 7.5

Total trail mixed by John= 10.3 + 12.3 + 7.5 = 30.1

30.1 cups was mixed together by John.
