The unit rate for doing chores is $1 per hour more than the unit rate for babysitting
Step-by-step explanation:
30 / 5 = 6
28 / 4 = 7                             the person above me was right 
 
        
                    
             
        
        
        
Answer:
Measure of minor angle JOG is 
Step-by-step explanation:
Consider a circular track of radius 120 yards. Assume that Cherie starts from point J and runs 200 yards up to point G.  
 .
.  
Now the measure of minor arc is same as measure of central angle. Therefore minor angle is the central angle  .
.
To calculate the central angle, use the arc length formula as follows.  
 
  
Where  is measured in radian.
 is measured in radian.
Substituting the value,
 
  
Dividing both side by 120,
 
  
Reducing the fraction into lowest form by dividing numerator and denominator by 40.
 
  
Therefore value of central angle is  , since angle is in radian
, since angle is in radian
Now convert radian into degree by using following formula,

So multiplying  with
 with  to convert it into degree.
 to convert it into degree.

Simplifying,

So to nearest tenth, 
 
        
             
        
        
        
The right answer is 
0.627
        
             
        
        
        
Answer:
y = -  x + 2
 x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m =  =
 =  = -
 = - 
The line crosses the y- axis at (0, 2) ⇒ c = 2
y = -  x + 2 ← equation of line
 x + 2 ← equation of line
 
        
                    
             
        
        
        
Answer:
<h2>Q = -6</h2>
Step-by-step explanation:
If the solution of the system of equations is {(x, y): x - y = 4} - infinitely many solutions, then this system is consistent and dependent.
x - 3y = 4            <em>multiply both sides by 2</em>
2x - 6y = 8
Therefore Q = -6
