Answer:
Now if the high and low monthly average temperatures satisfy the inequality, then the , monthly averages are always within 22 degrees of 43°F.
Step-by-step explanation:
The inequality describes the range of monthly average temperatures T in degrees Fahrenheit at a certain location.
The inequality expression is given as:

now this expression could also be expressed as:

Now if the high and low monthly average temperatures satisfy the inequality, then the , monthly averages are always within 22 degrees of 43°F.
( As the difference is 22 degrees to the left and right)
 
        
             
        
        
        
Answer:
9 ft
Step-by-step explanation:
Let's begin with the formula for the volume of a square pyramid.  If s is the base length, then the area of the base is s^2.  The volume of the pyramid is then V = (1/3)(base area)(height).  We know the volume and the base length (s), and want to find the height.  Solving V = (1/3)(base area)(height)
for height, we get:
3V = (base area)(height), or
     3V
---------------- = height
 base area
Substituting 75 ft^3 for V and (5 ft)^2 for base area, we get:
                3(75 ft^3)              9 ft
height = ------------------ = ----------------- = 9 ft
                  25 ft^2                   1
 
        
             
        
        
        
Answer:
Mark me as brainlist
Step-by-step explanation:
P = Perimeter            
L = Length          
W = Width
Perimeter of rectangle = L + L + W + W        
or P = 2L + 2W
You know:
P = 36 inches
L = 2W          [length is(=) 2 times it's width]
W = ?
P = 2L + 2W    
Substitute/plug in what you know, plug in 2W for L since L = 2W
36 = 2(2W) + 2W         Simplify
36 = 4W + 2W
36 = 6W        Divide 6 on both sides
6 = W              Now that you know the width, you can find the length:
L = 2W
L = 2(6)
L = 12
L = 12 in
W = 6 in
PROOF
P = 2(12) + 2(6)
P = 24 + 12
P = 36
 
        
             
        
        
        
Answer:
An =4^(n-1)
Step-by-step explanation:
hello :
the sequence is geometric because : (-64)/(-16) = (-16)/(-4)=-4/-1= 4=r
the nth term is :  An =A1 × r^(n-1)
a common ratio is : r  and A1 the first term
in this exercice :   r =4        A1 = 1
An =A1 × r^(n-1)
An =1 × 4^(n-1)=4^(n-1)
