Start by combining like terms:
Now we have:
Divide both sides by 2 to isolate s
Final answer:
s=12
A................................
This problem requires the use of the chain rule: dy / dt = [dy / dx] * [dx / dt]
y = √x => dy / dx = 1 / (2√x)
<span>(a) Find dy/dt, given x = 16 and dx/dt = 7.
dy/dt = [ 1/(2√x) ] * 7 = [1/(2*4)] * 7 = 7/8
(b) Find dx/dt, given x = 64 and dy/dt = 8.
dx/dt = [dy/dt] / [dy/dx] = 8 / [1/(2√64) ] = 128

Answer:
35.7142857143
Step-by-step explanation:
All you need to do is divide 250 by 7 because their are 7 days in a week.
A. Other crops: 35+25+20=80%
Beans: 100-80=20%
B. 300 acres×20%
=60 acres of cotton
C. Corn: 300×35%= 105 acres
Wheat: 300×25%= 75 acres
105-75= 30 more acres of corn than wheat
D. Yes, he is correct.
Corn fields+bean fields
35%+20%= 55%
