You kind of need to show more, but the independent variable would be something that you are changing to then measure the reaction, like the time left in for example.
Answer: It's the circulatory system
Explanation:
2.0 L in mL :
2.0 x 1000 => 2000 mL
1.26 kg in g :
1.26 x 1000 => 1260 g
D = mass / volume
D = 1260 / 2000
D = 0.63 g/mL
hope this helps!
Answer:
3 × 10¯¹⁰
Explanation:
9×10² ÷ 3×10¹²
The above expression can be simplified as follow:
9×10² ÷ 3×10¹²
Recall:
9 = 3²
9×10² ÷ 3×10¹² = 3²×10² ÷ 3×10¹²
Recall:
a^m ÷ a^n = a^(m – n)
3²×10² ÷ 3×10¹² = 3^(2 – 1) × 10^(2 – 12)
= 3¹ × 10¯¹⁰
Recall:
a¹ = a
3¹ × 10¯¹⁰ = 3 × 10¯¹⁰
