A bakery bakes 183 loaves of bread in 4 hours. How many loaves does the bakery bake in 1 hour?

Leona [35]

Answer:

45.75 loaves.

Step-by-step explanation:

I believe this is the answer as you would divide the amount of bread made (183 loaves) by the amount of time it took to make it. (4 hours) So it would be 183/4 which equals 45.75. To check your work, 45.75*4 =183.

Bess [88]

Answer:

x = 2/5

Step-by-step explanation:

$x^3=\dfrac{0.008}{0.125}=\dfrac{8}{125}=\dfrac{2^3}{5^3}\\\\x=\sqrt[3]{\dfrac{2^3}{5^3}}=\dfrac{\sqrt[3]{2^3}}{\sqrt[3]{5^3}}=\dfrac{2}{5}$

The value of x is 2/5.

Answer:

The minimum unit cost is equal to $15,339

Step-by-step explanation:

Let

x ----> the number of engines

C ---> the cost in dollars to make each airplane engine

we have

$C(x)=0.5x^{2} -100x+20,339$

This is a vertical parabola open upward (the leading coefficient is positive)

The vertex represent the minimum of the parabola

The minimum unit cost is equal to the y-coordinate of the vertex

Convert the quadratic equation into vertex form

Factor 0.5

$C(x)=0.5(x^{2} -200x)+20,339$

Complete the square. Remember to balance the equation by adding the same constants to each side

$C(x)=0.5(x^{2} -200x+100^2)+20,339-5,000$

$C(x)=0.5(x^{2} -200x+10,000)+15,339$

Rewrite as perfect squares

$C(x)=0.5(x-100)^{2}+15,339$ ----> equation into vertex form

The vertex is the point (100,15,339)

The y-coordinate of the vertex is 15,339

therefore

The minimum unit cost is equal to $15,339
