Answer:
<h2>0.</h2>
Step-by-step explanation:
First, we should line up the fractions.
6 / 7 - 6 / 7.
Second, we subtract straight across since denomionators are the same.
6 / 7 - 6 / 7 = 0.
Therefore, the difference is 0.
Just divide the original cost for one pound by 4 for each meat.
4.25 divided by 4. if it makes it any easier, 425 divided by 400 because you just move the decimal over and you will get the same result.
2.85 (or 285) divided by 4 (or 400).
then add the original cost per pound for each and then subtract turkey from beef.

Answer: ds/dt = 11</h3>
================================================
Work Shown:
Before we can use derivatives, we need to find the value of s when (x,y) = (15,20)
s^2 = x^2+y^2
s^2 = 15^2+20^2
s^2 = 225+400
s^2 = 625
s = sqrt(625)
s = 25
-----------
Now we can apply the derivative to both sides to get the following. Don't forget to use the chain rule.
s^2 = x^2 + y^2
d/dt[s^2] = d/dt[x^2 + y^2]
d/dt[s^2] = d/dt[x^2] + d/dt[y^2]
2s*ds/dt = 2x*dx/dt + 2y*dy/dt
2(25)*ds/dt = 2(15)*5 + 2(20)*(10)
50*ds/dt = 150 + 400
50*ds/dt = 550
ds/dt = 550/50
ds/dt = 11
-----------
Side note: The information t = 40 is never used. It's just extra info.
