____ [38]

9514 1404 393

Answer:

2876 books

Step-by-step explanation:

If we let y1 and y2 represent the costs from method 1 and method 2, then we have, for x books published, ...

y1 = 12841 +24.25x

y2 = 48072 +12x

These costs will be equal when ...

y1 = y2

12841 +24.25x = 48072 +12x

12.25x = 35231 . . . . . . . . . . . . . subtract 12841+12x

x = 2876 . . . . . . . . . . divide by 12.25

The costs will be the same for production of 2876 books.

An action movie production team needs glass spheres to hold a green liquid that looks like an explosive. If all of the available

Ivenika [448]

Answer:

6 inches

Step-by-step explanation:

3392.92 cubic inches of liquid distributed in 30 spheres would give each sphere's volume to be:

$\frac{3392.92}{30}=113.1$

Now we equate 113.1 to the formula for volume of a sphere and solve for r:

$\frac{4}{3}\pi r^3=113.1\\r^3=\frac{113.1}{\frac{4\pi}{3}}\\r^3=27\\r=\sqrt[3]{27} =3$

The radius of each of those spheres is 3

We know diameter is twice the radius , so diameter would be 3 * 2 = 6 inches
