Answer:
1680 kwhr
Step-by-step explanation:
See attached for explanation. I converted watt*hr to kW*hr by dividing by 1000.
Fans Bulbs
40 100
50 60 W
10 6 hours/day
20000 36000 W*hr/day
30 30 days/month
600000 1080000 W*hr/month
600 1080 kWhr/month
Total = 1680 kWhr/month
The rule for quotients of similar bases with different exponents is:
(a^c)/(a^b)=a^(c-b) in this case:
15^18/(15^3)=15^15
Answer:
39/18 = 13/6 = 2 1/6
Step-by-step explanation:
factors are 1,2,3,6,9,18
so the reciprocals are
1/1, 1/2, 1/3, 1/6, 1/9, 1/18
when added the sum is 39/18 or 2 1/6
It all depends where you start from, and what route you take.
For me, if I take the shortest possible route, then it's 3,956 miles to London
and 9,809 miles to Jakarta. So for me, Jakarta is 5,853 miles farther.
But if you're starting from, say, Singapore, then London is 6,192 miles
farther away than Jakarta.
