The answer is C. 23 is a term
Answer:
$68.27 for 1 hour
Step-by-step explanation:
$320.28 - $115.46 = $204.82
$204.82 / 3 hours of labour = $68.27 for 1 hour
X is a number so when u plus a letter that's still a number
Basically, what this asks you is to maximize the are A=ab where a and b are the sides of the recatangular area (b is the long side opposite to the river, a is the short side that also is the common fence of both corrals). Your maximization is constrained by the length of the fence, so you have to maximize subject to 3a+b=450 (drawing a sketch helps - again, b is the longer side opposite to the river, a are the three smaller parts restricting the corrals)
3a+b = 450
b = 450 - 3a
so the maximization max(ab) becomes
max(a(450-3a)=max(450a-3a^2)
Since this is in one variable, we can just take the derivative and set it equal to zero:
450-6a=0
6a=450
a=75
Plugging back into b=450-3a yields
b=450-3*75
b=450-225
b=215
Hope that helps!
Answer:x=33.6
Step-by-step explanation:
You would set up the equation 6/5 = x/28 Then you would cross multiply 6•28 then divide by 5
