Answer:
QSR = 68º
Step-by-step explanation:
TSQ + QSR = TSR
15x + (10x - 2) = 173
Combine like terms
25x = 175
Divide both sides by 25
x = 7
QSR = 10x - 2
QSR = 10(7) - 2
QSR = 68º
 
        
             
        
        
        
Answer:
Workdone = 2450Joules
Step-by-step explanation:
Let the top of the aquarium be at height 0.
Let the bottom of the aquarium be at height 1
F = mg = 2p◇x × g
F= 2000◇x × 9.8
F = 19600◇x
Workdone = 19600xdx
Total workdone = Integral (limits 0.5 -0)19600×dx
Total work = [9800x^2]^0.5
Total work= 9800× 0.5^2 = 2450 Joules
 
        
             
        
        
        
Test the choices !
Pick an even number, and see what each choice does to it.
Let's start with, say,  6 .
We'll try each choice, and see which one produces an odd number:
a).  6 to the 2nd power. . . . . .  6 x 6 = 36.  That's not an odd number.
b).  6 + 3  =  9  This could be it.  9 is odd. We'll save this one.
c).  3·6 = 18.  That's not an odd number.
d).  6/3 = 2.  That's not an odd number.
The only one that gave us an odd number is (b).
        
             
        
        
        
The answer is C,

Answer:
   102
Step-by-step explanation:
The total of ratio units is ...
   6 + 3 + 8 = 17
The difference between the Charlie's ratio units and Adrian's ratio units is ...
   8 - 6 = 2
That is, the total number of ratio units is 17/2 = 8.5 times that difference.
The actual difference is 12 sweets, so the total number of sweets is ...
   8.5 × 12 = 102 . . . . total sweets
