6,200,0 is the answer to that
Kate may have payed for 20 strawberries I'm not sure if that is right?? hope I helped
Answer:
Solid/freezing
Explanation:
Solid has the least energy of all of the phase changes and the more energy is lost the colder its gets then water turns into a solid called ice hope i helped!
Answer:
Hb would be 78.4% saturated.
Explanation:
This problem can be solved by using simple unitary method.
At 100 mm Hg pressure of oxygen, Hb is saturated by 98%
So, at 1 mm Hg pressure of oxygen, Hb is saturated by 
%
Hence, at 80 mm Hg pressure of oxygen, Hb is saturated by 
% or 78.4%
Therefore, at 80 mm Hg pressure of oxygen in the lungs, Hb would be 78.4% saturated.
Answer: 31 (a) 4 32 (a) 5
(b) 7 (b) 3
(c) 5 (c) 5
(d) 3 (d) 2
<u>Significant Figures (sf) Rules:</u>
1) Trailing zeroes are considered significant ONLY If a decimal point is provided.
2) Zeroes between the decimal point and number are NOT significant <u>unless</u> they are between numbers.
3) All digits in scientific notation are counted (disregard the exponent).
31 (a) 508.0 <em>trailing zero so use rule 1 </em> --> sf = 4
(b) 820,400.0 <em>trailing zero so use rule 1 </em> --> sf = 7
(c) 1.0200 x 10⁵ <em>scientific notation so use rule 3</em> --> sf = 5
(d) 807,000 <em>no trailing zeroes so use rule 1</em> --> sf = 3
32 (a) 0.049450 <em>zero between decimal point & #, use rule 2</em> --> sf = 5
(b) 0.000482 <em>zero between decimal point & #, use rule 2</em> --> sf = 3
(c) 3.1587 x 10 ⁻⁸ <em>scientific notation so use rule 3</em> --> sf = 5
(d) 0.0084 <em>zero between decimal point & #, use rule 2</em> --> sf = 2
