Answer:
Step-by-step explanation:
x+y = 175
y = 175 - x
f(x) = (x+3)(y+4)
= x(175-x) + 3(175-x) + 4x + 12
= 175x - x² + 525 - 3x + 4x + 12
= -x² +176x + 537
f'(x) = -2x + 176
maximum when x = 88
y = 175-x = 87

Correct answers:
A. An angle that measures
radians also measures ![30^o](https://tex.z-dn.net/?f=30%5Eo)
C. An angle that measures
also measures
radians
Step-by-step explanation:
Recall the formula to transform radians to degrees and vice-versa:
![\angle\,radians=\frac{\pi}{180^o} \,* \,\angle degrees\\ \\\angle\,degrees=\frac{180^o}{\pi} \,* \,\angle radians](https://tex.z-dn.net/?f=%5Cangle%5C%2Cradians%3D%5Cfrac%7B%5Cpi%7D%7B180%5Eo%7D%20%5C%2C%2A%20%5C%2C%5Cangle%20degrees%5C%5C%20%20%5C%5C%5Cangle%5C%2Cdegrees%3D%5Cfrac%7B180%5Eo%7D%7B%5Cpi%7D%20%5C%2C%2A%20%5C%2C%5Cangle%20radians)
Therefore we can investigate each of the statements, and find that when we have a
radians angle, then its degree formula becomes:
![\angle\,degrees=\frac{180^o}{\pi} \,* \,\angle radians\\\angle\,degrees=\frac{180^o}{\pi} \,* \,\frac{\pi}{6} \\\angle\,degrees=\frac{180^o}{6} \\\angle\,degrees=30^o](https://tex.z-dn.net/?f=%5Cangle%5C%2Cdegrees%3D%5Cfrac%7B180%5Eo%7D%7B%5Cpi%7D%20%5C%2C%2A%20%5C%2C%5Cangle%20radians%5C%5C%5Cangle%5C%2Cdegrees%3D%5Cfrac%7B180%5Eo%7D%7B%5Cpi%7D%20%5C%2C%2A%20%5C%2C%5Cfrac%7B%5Cpi%7D%7B6%7D%20%5C%5C%5Cangle%5C%2Cdegrees%3D%5Cfrac%7B180%5Eo%7D%7B6%7D%20%5C%5C%5Cangle%5C%2Cdegrees%3D30%5Eo)
also when an angle measures
, its radian measure is:
![\angle\,radians=\frac{\pi}{180^o} \,* \,\angle degrees\\\angle\,radians=\frac{\pi}{180^o} \,* \,180^o\\\angle\,radians=\pi](https://tex.z-dn.net/?f=%5Cangle%5C%2Cradians%3D%5Cfrac%7B%5Cpi%7D%7B180%5Eo%7D%20%5C%2C%2A%20%5C%2C%5Cangle%20degrees%5C%5C%5Cangle%5C%2Cradians%3D%5Cfrac%7B%5Cpi%7D%7B180%5Eo%7D%20%5C%2C%2A%20%5C%2C180%5Eo%5C%5C%5Cangle%5C%2Cradians%3D%5Cpi)

Answer:
Children: $13
Adults: $18
Step-by-step explanation:
Well for both sets we can set up the following system of equations,
![\left \{ {{3a + 4c = 106} \atop {2a + 3c = 75}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7B3a%20%2B%204c%20%3D%20106%7D%20%5Catop%20%7B2a%20%2B%203c%20%3D%2075%7D%7D%20%5Cright.)
So first we need to solve for a in the first equation.
3a + 4c = 106
-4c to both sides
3a = -4c + 106
Divide 3 by both sides
<u>a = -4/3c + 35 1/3</u>
Now we plug in that a for a in 2a + 3c = 75.
2(-4/3c + 35 1/3) + 3c = 75
-8/3c + 70 2/3 + 3c = 75
Combine like terms
1/3c + 70 2/3 = 75
-70 2/3 to both sides
1/3c = 4 1/3
Divide 1/3 to both sides
c = 13
Now we can plug in 13 for c in 3a + 4c = 106,
3a + 4(13) = 106
3a + 52 = 106
-52 to both sides
3a = 54
Divide 3 by both sides.
a = 18
