volume =  l x w x h
volume = 20 x 35 x 50  = 35,000 cubic cm
 1 cubic cm = 0.001 liter
35000 x 0.001 = 35 liters of water is needed
 
        
             
        
        
        
Answer:
Width of the rectangle = 5 inches
Length of the rectangle = 20 inches
Step-by-step explanation:
Let us assume the width of the rectangle = m  in
So, the length of the rectangle = 4 (Width) = (4 m) in
Perimeter of the rectangle = 50 inches
Now, Perimeter of the Rectangle = 2 (LENGTH + WIDTH)
⇒ 2( m + 4m)  = 50
or, 2(5m) = 50
⇒ 10m = 50  or, m = 50/10 = 5
⇒ m = 5
So, the width of the rectangle = 5 inches
and the length of the rectangle = 4 m = 4 x 5 = 20 inches
 
        
             
        
        
        
1) 1/4 + 1/4 + 1/4 + 1/4 + 1/4 + 1/4 = 1 Cup and a half.
        
                    
             
        
        
        
For this case we have that by definition, the Pythagorean theorem states that:

Where:
a, b: Are the legs
c: It is the hypotenuse
According to the figure we have to:

Substituting in the formula we have:

Answer:
Option D
 
        
             
        
        
        
3/4 × 20 = 5/6y
60/4 = 5/6y
360 = 30y
y = 12
