Step-by-step explanation:
Solve the bracket first. starting with multiplication and then subtraction 
0.00035 + (4.2 x 10-5)
0.00035 + (42-5)
0.00035 + 37
0.01295
 
        
             
        
        
        
Width:  W
length: L = 5W
Use the Pyth. Theorem to find the length of the diagonal:
|D| = sqrt(W^2 + [5W]^2) = sqrt(W^2 + 25W^2) = sqrt(26W^2), or 
                                                                            Wsqrt(26)   (ans.)
        
                    
             
        
        
        
Answer:
120
Step-by-step explanation:
Im not sure but 1.25 equals 1 1/4   and 16 cups equal a gallon.
 16 divided by 1.25 is 12 which means that 12 of those ten servings equal a gallon.  10 times 12 is 120 which becomes ur answer. Once again im not sure but i hope that ive helped.
 
        
             
        
        
        
Answer:
90°
Step-by-step explanation:
ABC ~ DEF so that means E = B.  A triangle has to add up to 180° so that means 180-35-55=90
 
        
             
        
        
        
The range is 6. because the highest number is 21 and the lowest is 15.
 (21-15=6). hope i helped !
