9, 14, and 22.
The formula for checking if a triangle will work is side a + side b > side c.
The only one that works is 9, 14, and 22.
Answer:
4/7 is larger than 2/7
Step-by-step explanation:
2/7 is 2÷7
4/7 is 4÷7
Answer:
The correct answer is 10 for lowest average cost and the cost function is 0.2
+ 75x + 20.
Step-by-step explanation:
Average cost function is given by = 
= C(x) = 0.2x + 
+75.
For minimizing we need to find 
C(x) = 0.
⇒ C(x) = 0.2 - 
.
⇒ = 0.2
⇒ = 100.
⇒ x = ±10
⇒ x = 10 ; cost cannot be negative.
Second order derivative is positive which implies the average cost minimizes.
Original cost function is given by C(x) × x = 0.2 + 75x + 20.
Let A and B be the mL of each solution needed.
quantity equation
A + B = 360
concentration equation
0.5A + 0.6B = 0.53(360)
use A = 360 - B for substitution in the other equation.
0.5(360 - B) + 0.6B = 190.8
180 - 0.5B + 0.6B = 190.8
180 + 0.1B = 190.8
0.1B = 190.8 - 180
0.1B = 10.8
B = 10.8/0.1
B = 108 mL
then A+B = 360
A + 108 = 360
A = 360 - 108
A = 252 mL
