Answer:

\large\boxed{d_2=15\ cm}

Step-by-step explanation:

The formula of an area of a kite:

A=\dfrac{d_1d_2}{2}

d₁, d₂ - diagonals

We have A = 120 cm² and d₁ = 16 cm. Substitute:

\dfrac{16d_2}{2}=120

8d_2=120           <em>divide both sides by 8</em>

d_2=15\ cm

Which of the following expressions is correct? Select one: a. marginal cost = (change in quantity of output)/(change in total co
Natasha_Volkova [10]

Answer:

b. average total cost = total cost/quantity of output

Step-by-step explanation:

The marginal cost is the additional cost of producing one more unit of output and it can be calculated by taking the change in total cost and dividing it by the change in quantity, its formula is:

  • <em>Marginal cost = change in total cost/ change in quantity</em>

The average total cost (sometimes referred to simply as average cost) is total cost divided by the quantity of output, its formula is:

  • <u><em>Average total cost = total cost / quantity of output</em></u>

The total cost is obtained adding together the fixed costs and the variable costs, its formula is:

  • <em>Total cost = fixed cost + variable cost</em>

The average variable cost is obtained when variable cost is divided by quantity of output, its formula is:

  • <em>Average variable = variable cost / quantity of output</em>

I hope you find this information useful and interesting! Good luck!

15 + (5-x)/x=30 solve for x
elixir [45]

Answer:

5/16

Step-by-step explanation:

15+(5-x)/x=30

1) Subtract 15 from both sides:

(5-x)/x=15

2) Multiply both sides by x:

5-x=15x

3) Add x to both sides:

16x=5

4) Divide both sides by 16:

x=5/16
