so it becomes 2/3,6/5,12/7,20/9, so we have that the numerator is [number in sequence]^2+[number in sequence] and the denominator is 2*[number in sequence]+1 so we have that the 12th number in the sequence is ((12*12)+12)/(2*12+1)=(144+12)/25=156/25=6 6/25 so the 12th term is 156/25 or 6 6/25

so 50 out of 100 is 50/100=1/2=50% so since the other one is 62% we multiply them by 100 to get 62 and 62-50=12 so it is 12/(100/2)=12/50=6/25=24% so our final answer is 24%

so the first sequence is (18-8)*48+18=498 and the last number is -232 so the formula is (498+-232)*99/2=13167 so the sum of the 99 terms is 13167

We round the thousandths place and that number will become the number that you want with 2 deciamls for example 1/7=0.14258...≈0.142≈0.14

an incircle is where the point that the bisectors intersect that forms a circle touching the sides of the triangle 

so we have that OD=4 , BD=6, and DC=8 so BC=14 and we can find the area so they are 14*4/2*2=64 so the area of the pentagon OECBF where O is the incenter and E is where they intersect AC and F is where they intersect AB. We only need to find AEOF which is 2 times AOF so the height of AOF is 4 and the base is x so we get that the area is 2x+64 

we make them have a LCM denominator which is 30 so the equation beomes 4 9/30 + 3 12/30+ 10/30 + 15/30 but then we change the 4 9/30 into 129/30 and 3 12/30 becomes 102/30 so the equation becomes  (129 + 102 + 10 + 15)/30=256/30=128/15=8 16/30=8 8/15 so our final answer is 128/15 or 8 8/15

so we get that 1/2=0.5 and so the equation becomes 0.75-0.25+0.5=1 so our final answer is 1.

so we have that 1/2=0.5 and 3/8=0.375 so when we plug them in we have 9.25-0.5+0.375=9.125=9 1/8 so our final answer is 9.125 or 9 1/8.

so we have sqrt(10^2+10^2) which is sqrt200 so the area of the square is 200 and then we do 10*10/2=50 so the area is 200-60=150

ok thanks
