Answer:
-13/7
Step-by-step explanation:
2x+5(x+1)=-8
2x+5x+5=-8
7x+5=-8
7x=-8-5
7x=-13
7x/7=-13/7
x=-13/7
The formula for the sum of the a finite geometric series is this:
Sn = a((1-r^n) / (1-r))
The given values are:
n = 30
a = 0.5 mi
r = 1.10 (10% more each day)
S30 = 0.5 ((1-1.10^30) / (1-1.10))
S30 = 82.25 mi
After 30 days, he will have traveled 82.25 miles.
Answer:
7650 W-h
Step-by-step explanation:
1 day = 24 hrs
4 days and 6 hours = 4(24) + 6 = 102 hours
given
24 hrs (i.e 1 day) ------> consumes 1800 W-h
1 hour ------> consumes 1800/ 24 = 75 W-h
102 hrs (i.e 4 days 6 hrs) = 75 W-h x 102 = 7650 W-h
It means 2.5m/s multiplied by 2500 to get the total distance in meters
Answer:
(-30, 10)
multiply -20/60 by -0.5 each and you get 10/-30
this is the only pair achievable by proportion.
