We can conclude that <span> the number representing the amount of calcium in the liquid will have
two significant figures.</span>
The answer is 1/2. The reasoning is 1/2 x 1/2=1/4 1/4 x 1/2=1/8 fractions multiply on numerator and denominator then simplify
Answer:
The answer is 4/5
Step-by-step explanation:
-1/2 y ≤ -2/5
1/2y ≤ 2/5
