S_A_V [24]

Answer:

n=7

Step-by-step explanation:

(7^2)^4= n^8

We know that a^b^c = a^(b*c)

7^(2*4) = n^8

7^8 = n^8

There are 30 books on the library shelf, Sam noted that 1/6 of them are non fiction. Dan notes that 3/5 of the books are fiction
ehidna [41]

Answer:

7

Step-by-step explanation:

Fiction books:  (1/6) of 30 books = 5 books

Non-fiction books:  (3/5) of (30) books = 18 books

The subtotal here is 5 + 18, or 23.  

23 of the books are either fiction or non fiction.

30 - 23, or 7, of the books remain (are neither fiction nor non-fiction).

What is the volume rounded to the nearest whole number?
Semenov [28]

Answer:

13 in³

Step-by-step explanation:

This is a skewed pyramid, but that doesn't change the way you find the volume of the figure.

The formula for the volume of a pyramid is 1/3(b)(h)

Multiply 6 by 6.5 to get 39, then divide it by 3 to get 13 in³
