Answer:
<em>T </em><em>=</em><em> </em><em>1</em><em>6</em>
Step-by-step explanation:
As triangles are similar
AB/DE = BC/EF = AC/DF
13.5/18 = 6/4 = 12/T
3/4 = 3/4 = 12/T
3/4 = 12/T
T = 12×4/3
T = 16 
 
        
             
        
        
        
Perform indicated multiplication on left side first...
-5x-35<-10  add 35 to both sides
-5x<25  divide both sides by -5 (you must reverse sign because of division by a negative value too!)
x>5  or if you prefer...
x=(5, +oo)
        
             
        
        
        
Answer:
A.)  9pencils
B.)   6 more Pencils than markers
Step-by-step explanation:
A.)1.08/ 0.12 = 9 
B.) 2.18 - 1.08 = $1.10
1.10 / .36 = 3 Markers

Answer:
  h /r  =  2.55
Step-by-step explanation:
Area of a can:
  Total area of the can = area of (top + bottom)  + lateral area
lateral area  2πrh    without waste
area of base (considering that you use 2r square)  is 4r²
area of bottom      ( for same reason )                           4r²
Then Total area  =  8r² + 2πrh
Now can volume is   1000 = πr²h        h = 1000/πr²
And  A(r)  =   8r² + 2πr(1000)/πr²
A(r)  =   8r² + 2000/r
Taking derivatives both sides
A´(r)   =  16 r    - 2000/r²
If A´(r)  =  0              16 r    - 2000/r²   = 0
(16r³  - 2000)/ r²  =  0        16r³  - 2000  =  0
r³  =  125       
r = 5 cm      and      h  = ( 1000)/ πr²      h  = 1000/ 3.14* 25
h = 12,74  cm
ratio   h /r  =  12.74/5         h /r  =  2.55
     
 
        
             
        
        
        
Answer:
They switched the w and the -15 at the end
Step-by-step explanation:
When you switch the inequality sign after multiplying or dividing a number, the variable stays on the side its on, even if it looks weird.
