Let n be the amount of time it takes william to cut the lawn. Then Shelly takes
n-2 hours. So:
1/n+1/n-2=1/3
3(n-2)+3n=n²-2n
6n-6=n²-2n
n²-8n+6=0
Using the quadratic formula, we get a positive value of 7.1623 hrs as the amount of time william takes working alone, and 5.1623 as the amount  of time Shelly takes working alone

Answer:
   1131.0 m³
Step-by-step explanation:
Using the formula for the volume of a cylinder, fill in the appropriate values and do the arithmetic.
   V = πr²h
Since this formula needs the radius of the cylinder and you are given the diameter, you must divide the diameter by 2 to get the radius:
   r = d/2 = (12 m)/2 = 6 m
Then the volume is ...
   V = π(6 m)²(10 m) = 360π m³ ≈ 1131.0 m³ . . . . . rounded to tenths
 
        
             
        
        
        
Answer:
   5√2 is as simple as it gets
   5√2 ≈ 7.071068
Step-by-step explanation:
One simplifies radical expressions by removing from under the radical any squares that might be there. 2 is a prime number, so has no square factors. The simplest form of this radical expression is the one given:
   5√2
Your calculator can tell you the value of this irrational number is about ...
   5√2 ≈ 7.071068
 
        
             
        
        
        
Answer:
Step-by-step explanation:
The sine of an angle is equal to the cosine of its complement, and vice versa.
   sin ∠QOP = cos ∠ROQ
   cos ∠ROQ = sin ∠QOP
 
        
             
        
        
        
The slope would be 2/3 because that would leave pounds when multiplied by cups.
add 0.5 for the weight of the water jug
y = (2/3)x + 0.5
