Jay has an album that holds 600 coins. Each page of the album holds 6 coins. If 39% of the album is empty, how many pages are

Nutka1998 [239]

9514 1404 393

Answer:

Step-by-step explanation:

If there are 6 coins on each page, then the number of pages for 600 coins is ...

(600 coins)/(6 coins/page) = 100 pages

If 39% are empty, then 100% -39% = 61% are filled.

The number of filled pages is ...

61% × 100 = 61/100 × 100 = 61 . . . . pages filled

_____

<em>Comment about percent</em>

You can think of the percent symbol (%) and "per 100" (/100) as being interchangeable. 61% = 61/100

("Cent" is used to signify one of 100 parts. A cent is 1/100 of a dollar, for example. In land area, a cent is 1/100 of an acre. Then, "percent" can be thought of as "per cent" or "per 100 parts".)

A side of a square is A = 8^(3/2) inches. Using the area formula A = s2, determine the area of the square.?A = 24 square inches

VLD [36.1K]

Answer:

512 square inches

Step-by-step explanation:

If A = s², and $s=8^{\frac{3}{2}}$ , then

$A=s^2=(8^{\frac{3}{2}})^2$ and

$A=s^2=8^{\frac{6}{2}}$ which simplifies to

$A=s^2=8^3$ which simplifies to

$A=s^2=512$

Therefore, if $A=s^2$ and $s^2=512$ , then

A = 512 square inches
