Answer: 25</h3>
Explanation:
The "large cars" pie slice takes up 7% of a full circle. This means that the degree measure of this slice takes up 7% of a full 360 revolution.
7% of 360 = 0.07*360 = 25.2 degrees
This then rounds to 25 degrees

Answer:
4.13E23 molecules
Step-by-step explanation:
Molar mass HCl = 36.4611 g/mol
25.0g = 25/36.4611 = 0.686 mol HCl
1 mol HCl = 6.022*10^23 molecules
0.686 mol = 0.686*6.022*10^23 = 4.13*10^23 molecules.
Kenny sold his sneakers for $45, 60*.25(which is 25%)= 15, but that is 25% of 60, so you need to subtract that from 60, which is $45. If you use the same principle for 30%, you end up with $42. Subtract 42 from 45, and your answer is $3.
