At a bookstore, 960 books were placed on the discount shelf for 70% off the regular price. If 2/3 of the books sold, how many bo

Brrunno [24]

Answer: a. 320 books

Step-by-step explanation:

Given : The total number of books were placed on the discount shelf for 70% off the regular price = 960

The fraction of books sold = $\dfrac{2}{3}$

Then, the number of books sold = $\dfrac{2}{3}\times960=640$

Now, the number of books remain on the discount shelf = $960-640=320$

Hence, the number of books remain on the discount shelf =320

Find the volume of a pyramid with a square base, where the side length of the base is

MatroZZZ [7]

Answer:

1529.4 m^3

Step-by-step explanation:

We will use the formula V = 1/3*h*B for the volume of the pyramid, where V is volume, h is height, and B is are of the base.

First, since we know h and are looking for V, we need B. To find this, since it has a square base, we multiply b, the base length, by itself. 15.3m * 15.3m = 234.09m^2.

Next, we plug into the formula.

V = 1/3*19.6m*234.09m^2

And simplify:

V= 1/3 * 4,588.164m^3

V= 15.29.3879....

Last, round to the tenth

1529.4 m^3

OLEGan [10]

$a^2 + b^2 = c^2\\\\30^2 +b^2= 50^2\\\\b^2 = 50^2 - 30^2\\\\c = \sqrt{1600}\\\\c =40$

The length of the other leg is 40 millimeters.
