1) y = 0.5x^2 - 12x + 150 axis of symmetry x = -b/(2a) x = 12/1 = 12 y = 0.5(x^2 - 24x + 144) - 72 + 150 y = 0.5(x - 12)^2 + 78 vertex = (12, 78) 2) The vertex is the minimum point, and the minimum cost y = $78. 3) x = 12 cakes to yield minimum cost.

Tasya [4]

squash = cordial + water

400 ml = 50 ml + x ml

350 ml = x ml

Therefore, 350 ml are water.

350 ml / 400 ml = 0.875 = \frac{350}{400} = \frac{35}{40} = \frac{7}{8}

So the answer is 7 / 8

In Kite KLMN, find the measure of
Degger [83]

Answer:

M = K =

<h3>101°</h3>

Step-by-step explanation:

M = K, because it's a kite.

  • Kite has 2 angles on the left and right, each with the same size,
  • The kite also has different angles at the other angle points.

(Addition of kite angles result in 360°)

Therefore

360 = 63 + 95 + 2M

2M = 360-63-95

2M = 202

M = 202÷2

M = K = 101°

The size of each angle M and angle K = 101 degrees.

Arturiano [62]

Answer:

We'll use the variable x to represent last year's price. First, we have to set up an equation:

We get this equation because $13.25 is 6% MORE than last year's price, meaning we need to add the original price to the increase. Next, we combine like terms and solve for x:

Last year's price was $12.50.
