First find the speed...
8 miles per 3 hrs
8/3 = 2 2/3 m/hr
2 2/3 m/hr × x/3 m =
2 2/3 ÷ 3 = x
8/3 ÷ 3 = x
8/3 × 1/3 = x
8/9 = x
It takes 8/9 of an hour to run 3 miles. Multiply 8/9 × 60 to find out how many minutes.
8/9 × 60 = 53.33 minutes
The sum of a geometric sequence is:
s(n)=a(1-r^n)/(1-r), s(n)=nth sum, a=initial value, r=common ratio, n=term #
In this case we are told that a=6 and r=1/3 so:
s(n)=6(1-(1/3)^n)/(1-1/3)
s(n)=6(1-(1/3)^n)/(2/3)
s(n)=9(1-(1/3)^n), so the sum of the first 5 term is:
s(5)=9(1-(1/3)^5))
s(5)=9(1-(1/243))
s(5)=9(242/243)
s(5)=2178/243
s(5)=242/27
s(5)=8 26/27 ...if you wanted an approximation s(5)≈8.96 to the nearest hundredth...
Answer:
720
Step-by-step explanation:
15×6×8=720
if you multiply them all together it gives you the amount of possible options.
125+5(25) =10(25) --> 250=250, so the answer is 25 workout days
Answer:
z×(-5+3)then you complete the sum and that is your answer
