Answer:
10 months
Step-by-step explanation:
Because he was at $-1,000 and he deposited $100 a month that he earns from watching the dogs so it took him 10 months to realize that his bank account is now at $0
You take 720 and divide by 4 for the 4 weeks. Then you divide by 6 for each of the day and then you reach your answer.
Answer:
z= 69
Step-by-step explanation:
79+122+90+z=360 angle sum property
360-291=69
so z=69 degree
Suppose:
C=cost
c=cost per kilo-watt hour
w=number of watts
h=number of hours
thus
C=kwhc
where:
k=constant of proportionality:
k=C/(whc)
but
C=15 when w=6000, h=10/60=1/6 hours, c=7.5 cents per kw/h
thus
k=15/(6000*1/6*7.5)
k=0.002
thus:
C=0.002(whc)
hence:
when
h=70*2=140=140/6=70/3 hours the cost will be:
C=0.002(6000*70/3*7.5)
C=2100 cents
C=$21
