i love these types of problems! i'm going to use my name, cherry, if that's ok.
cherry had 10 buttons in her collection. cherry made a deal with a friend that allowed her to receive 5 new buttons per week. after a certain number of weeks, cherry had acquired a total of 50 buttons! how many weeks had cherry's friend given her buttons?
- cherry :)
Divide the distance by the speed:
10^8 / 10^5 = 10^3 days ( 1,000 days)
8.5 is opp of the angle and 14.5 is the hypotenuse.
Sin(X) = opp/hyp
or you can use Sin-1(opp/hyp) = X
Sin-1(8.5/14.5)=X
X= 35.8 or 36 rounded
5/14 and 1/16 is in simplest form
The answer is 5 because each quarter of an hour is 1 1/4 and 1 1/4 x 4 = 5
