Yes, they can have both positive and negative oxidation numbers.
Answer:
19.65°
Step-by-step explanation:
Use tan when you don't have the hypotenuse.
tan(y) = opposite/adjacent
tan(y) = 5/14
y = (tan^-1)(5/14)
y = 19.65°
Answer:
Hours of work= 3.5
Step-by-step explanation:
Giving the following information:
Allowance= $5
Hourly pay= $7.5
Desired profit= $31
<u>To calculate the number of hours to work, we need to use the following formula:</u>
Hours of work= shoveling pay / hourly pay
Hours of work= (31 - 5)/7.5
Hours of work= 26/7.5
Hours of work= 3.5
We know that 5 x 5 = 25, so the only answer choice with a 5 in it is 0.5
0.5 x 0.5 = 0.25, and the square root of that just equals 0.5.
Answer: C. 0.5
