In the US shoe sizes and foot length are related byt he formula s=3f-24 where s represents the shoe size and f represents the foot in length in inches
Solve this formula for f, foot length in terms of s, shoe size
are you just asking for rearrangement?
if so,
(s+24)/3=f
I'm not sure because that's all the question is asking? But from what it looks like, does it just need rearranging? There's another question after that which is : According to this formula if you wear a size 15 shoe how long is your foot
Is the formula they gave wrong
This is not the right formula
yeah just plug in the 15 for s into your formula and rearrange to find f, foot length
13?
13 in is the length of the foot if its a size 15 shoe. that's a big foot
In the formula what is the number 3 and 24 for
they might be products of the proof that derived that formula
To solve the equation s = 3f - 24 for f (foot length), we need to isolate f on one side of the equation. Here's how you can do it step by step:
1. Start with the equation: s = 3f - 24.
2. Add 24 to both sides of the equation to isolate the term with f:
s + 24 = 3f.
3. Divide both sides of the equation by 3 to solve for f:
(s + 24) / 3 = f.
Therefore, the equation f = (s + 24) / 3 represents foot length (f) in terms of shoe size (s).
