6/7 - 6/7 = ? Help please.
swat32

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.

Can you please please help me in this Math Question!!!!! Be sure to Show Your Work/Steps!!!!!

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.

Please help, this chapter was on derivatives...
Usimov [2.4K]
<h3>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.
