1/3 + 1/4 and the the sinplest form
Verizon [17]
The least common multiple between 3 and 4 is 12, so we can use this fact to rewrite both 1/3 and 1/4 in 12ths:

\big( \frac{1}{3}\times \frac{4}{4}\big) + \big(\frac{1}{4}\times \frac{3}{3}\big)=\\ = \frac{4}{12}+ \frac{3}{12}\\\\ = \frac{7}{12}

We're left with an answer of 7/12, which can't be reduced.

When no more than 110 units are produced, the cost of producing y units is given by C(x).
Maslowich

Producing 73.8 units gives the lowest possible average cost.

The average cost (AC) is the ratio of the total cost to the number of units produced. It is given by:

AC = C(x) / x

AC = (0.2x³ – 24x² + 1514x +30064) / x

AC = 0.2x² - 24x + 1514 + 30064/x

The lowest possible average cost is at AC' = 0. Hence differentiating the average cost, gives:

AC' = 0.4x - 24 - 30064/x²

0.4x - 24 - 30064/x² = 0

0.4x³ - 24x² - 30064 = 0

Solving the cubic polynomial gives:

x = 73.8 units

Therefore the lowest possible average cost is when 73.8 units are produced.

Select the correct answer
xxMikexx [17]

Answer:

Option B. 220

Step-by-step explanation:

Let

x ----> the number of student tickets sold

y ----> the number of adult tickets sold

we know that

x+y=360

y=360-x ----> equation A

3x+5y=1,360 ----> equation B

Solve the system by substitution

substitute equation A in equation B

3x+5(360-x)=1,360

solve for x

3x+1,800-5x=1,360

5x-3x=1,800-1,360

2x=440

x=220\ student\ tickets
