3/x=36
Multiply both sides by x
3=36x
Then divide both sides by 36
3/36=x
1/12=x
Final answer: 1/12
        
             
        
        
        
Step-by-step explanation:
Angle:2x+30+3x=180
Angle:2x+b+2b=180( Being in straight line)
Angle:30+3x+a=180
 
        
             
        
        
        
E+(e-24)=126
2e-24=126
2e=150
e=75
So (s)he recieved 75 and 75-24=51 emails  on those days.
        
             
        
        
        
Answer:
Amount of fresh water = 3.5 * 10^7 cubic kilometers
Step-by-step explanation:
Given the following
Total water on earth = 1.4×10^9 cubic kilometers
If 2.5% of it is fresh water
Amount of fresh water = 2.5% of 1.4×10^9 
Amount of fresh water = 0.025 * 1.4×10^9
Amount of fresh water = 0.035 * 10^9
Amount of fresh water = 3.5 * 10^7 cubic kilometers
 
        
             
        
        
        
Answer:
The largest area enclosed is  A = xy = 6 feet  6 feet = 36
 6 feet = 36 
Step-by-step explanation:
i) The perimeter of the area is 2 (x + y) =24  ∴ x + y = 12    ∴ y = 12 - x
(x + y) =24  ∴ x + y = 12    ∴ y = 12 - x
ii) The area of rectangle enclosed A  = xy    ⇒ A  = x ( 12 - x) = 12x - 
iii) differentiating both sides of the equation in ii) we get
 ⇒  x = 6 feet
    ⇒  x = 6 feet
iv) Differentiating both sides of equation in iii) we get     =  -2
 =  -2
    Therefore the area enclosed is maximum as the double derivative is negative
v) therefore for largest area enclosed   x  = 6 feet and  y = 12 - 6 = 6 feet
vi) therefore the largest area enclosed is 
  A = xy = 6 feet  6 feet = 36
 6 feet = 36
