Π radians = 180°
5 π / 4 = 5 · 180° / 4 = 900° / 4 = 225°
cos ( 5π/4 ) = cos 225°
With the unit circle we can find the exact value:
cos 225° = - √2 / 2 ≈ - 0.7071

The number of computers sold has to be 30% more than 48.
30% of 48 plus the numbers sold last month

Round up because the numbers has to be an integer value. (You can't have 2/5 of a computer).

63 computers

Zolol [24]


Well if her simplifies 1 3/7 to 1 1/2 and 5 4/5 to 6 then he would be overestimating because 1 1/2 is greater than 1 3/7 and 6 is greater than 5 4/5

Hope this helps!
