Answer:
   (b)  Hiking 10 feet due north, then hiking 10 feet due south
Step-by-step explanation:
Any pair of numbers that totals zero will be a pair of opposites. The offered choices are ...
   +6 -4 = 2 . . . not zero
   +10 -10 = 0
   +2 -3 = -1 . . . not zero
   +5 -3 = 2 . . . not zero
Hiking 10 feet due north, then hiking 10 feet due south is a situation involving opposite numbers adding up to zero.
 
        
             
        
        
        
1)  The amount M 1 IS $20 increases by 10% = 10 % *(20) + 20 = 22
2) The amount M1 decreases by 10% = 22- (10%*22) = $ 19,8 IS THE AMOUNT that i earn each week
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
Join OB.
∠A=∠A  (common)

∴ ΔAPO and ΔAOB are similar.

∠P=∠O
∠Q=∠B
So PQ║OB
Similarly RS║OB
∴PQ║RS

Answer:
   2800 tiles
Step-by-step explanation:
Each tile has an area of (0.05 m)² = 0.0025 m². Then the number of tiles required to cover 7 square meters is ...
   (7 m²)/(0.0025 m²/tile) = 2800 tiles
It will take 2800 tiles to cover the entryway.
