Ok so this can get tricky, it is basically just asking for you to perform many unit conversions. I'll try to simplify it for you here while still maintaining the explanation. If you have any questions about this process feel free to message me.
3 yards = ____ miles (conversion factor is 1760 because there are 1760 yards in a mile)
3/1760 = 0.017 miles,
Now we just need to convert seconds to hours.
1 second is how many mins, then how many mins in an hour?
360 seconds in an hour.
Ok now we just need to combine these two pieces of info,
0.017/360 = 4.72222 miles per hour. Thus 4.72 is the answer.
Answer:
Let fertilizer be F
and peat moss be P
since F is proportional to P
F = kP
where, k = constant of proportionality
k = F/P
putting in the values,
k = (3/4) /12
k = 3/4 * 1/12
k = 1/16
Therefore the constant of proportionality is 1/16.
Answer:
see explanation
Step-by-step explanation:
Using the rules of exponents
⇔ 
and 
= 1
Substitute the values of x into 
x = 0 → 
= 1 ⇒ a = 1
x = 2 → 
= 
= 
, hence
b =
x = 4 → 
= 
= 
, hence
c =
I think this answer is right but not 100% sure, 5 Root of 15 + 3
