Answer:
37.5
Step-by-step explanation:
if it decreases by 1/2 every 8 hours;
( 3×8= 24)
the first 8 hours 1/2×300 =150 gram
the second 8 hours(16 hours) = 1/2×150=75 gram
the third 8 hours(24 hours) = 1/2×75= 37.5gram
Answer:
-5x^4y^3
Step-by-step explanation:
so you divide -25 by 5 and the rule is if it is division for exponents then you subtract the exponent so 6-2=4, 7-4=3, 3-3=0. z^0 is 1 so we don't have to write it out.
Answer:
7
Step-by-step explanation:
As you can see, each time (let's say n) increases by 1, it divides by 1/2. So from a1 to a2, you get 28/2 or 14, then from a2 to a3, 14/2 or 7.
7 being your answer.
