1. 4*3/2-1*2/2+1*1=6
2.4*4-(3*4/2)-(4*3/2)=4
3.4*4-1-1/2-(3*3/2)-(1*4/2)-((1*2/2)*2)=6
I'm really sure that 0.1=1/10 since it is 1 out of 10 and the 1 is in the tenths place so it is \(\Huge{\dfrac1{10}}\)
We have 1*6*5*3=90 ways to do this
we have 1/5 for pink roses,1-6/10=4/10=2/5 red flowers, 6/10-1/5=3/5-1/5=2/5 pink carnations, 2/5*3/4=6/20=3/10 red carnations we add them up to get 2/5+3/10=7/10=70% so our final answer is 70%
it equals 3+3+3+3+3 for the ones below 9 and 4+4+4+4+4+4+4 for the ones from 10 ~16 and 5+5+5+5+5+5+5+5+5 for the ones 17~25 and 6+6+6 for 26~29 when we add them together we have 3+3+3+3+3+4+4+4+4+4+4+4+5+5+5+5+5+5+5+5+5+6+6+6=106 so our final answer is \(\lceil\sqrt{5}\rceil + \lceil\sqrt{6}\rceil + \lceil\sqrt{7}\rceil + \cdots + \lceil\sqrt{29}\rceil=\boxed{106}\)
I mean 900 points
Um about 900 I guess and I am in the leaderboard
Which website?
we have (9+8+7)/2=12 and (sqrt(12(12-9)(12-8)(12-7)))/8 to find the altitude and we find that the altitude is sqrt720/8=sqrt(11.25) then we can use the pythagorean's theorem to have sqrt(49-11.25)=sqrt37.75 and (((8-2sqrt37.75)+8)*sqrt11.25)/2=8sqrt11.25-sqrt424.6875
anyways i'll answer them
