LAW 2: The second law of indices tells us that when dividing a number with an exponent by the same number with an exponent, we have to subtract the powers. In algebraic form, this rule is as follows . The a represents the number that is divided by itself and m and n represent the powers.
Answer:
22 grams
Step-by-step explanation:
loses 50% of it's mass per 22 years
so after 22 years the mass would be 44 grams
22 years later would leave 50% of 44 grams = 22 grams

32 is the total
Answer:
There the buoy is 17.3 m from the place where the diver started.
Step-by-step explanation:
a² + b² =c²
⇒ 10² + b² = 20²
⇒ 100 + b² = 400
⇒ b² = 400 - 100
⇒ b²= 300
⇒ b = 
⇒ b = 17.3 m
There the buoy is 17.3 m from the place where the diver started.
Answer:
60
Step-by-step explanation:
If we assume that the line is 180 degrees, we can subtract 180 and 120, to get 60. So f is 60.
