Tan(30o)= ?/25
25 * tan(30o) = ?
? = 14.4
-- Cut the sheet in half.
-- Put one half-sheet on top of the other half-sheet.
Cut the stack of 2 halves in half.
-- Put one stack of two quarter-sheets on top of the other stack of quarter-sheets.
Cut the stack of 4 quarters in half.
Now you have eight one-eighth sheets.
Three cuts.
Taking Sam (3 x 5) = 15 minutes, plus a few seconds for set-up between cuts.

Answer:
2y² + 9
---------------
15y³
Step-by-step explanation:
Start by identifying the LCD, and then change each fraction so that its denominator is the LCD.
Here the LCD is 15y³, which is evenly divisible by 15y and 5y³.
Focus now on the first fraction: 2 / (15y). Multiplying numerator and denominator of this fraction by y² results in
y²·2 2y²
--------- → ----------
y²·15y 15y³ ←This is the correct LCD
Multiplying numerator and denominator of the second fraction by 3 results in:
3·3 9
------------ → ---------
3·5y³ 15y³ ←This is the correct LCD
So now those two original terms look like:
2y² 9
--------- + --------
15y³ 15y³
and this can be written in simpler form as:
2y² + 9
---------------
15y³
800,000. This is because the 8 is in the hundred thousandth spot. Because of this, the value of the 8 is eight hundred thousand.
