I think its 7 or 10 Dont remember that question
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
Answer:
Step-by-step explanation:
Simplify the expression -4x^2(3x − 7).
A. -12x^3 + 28
<h2>B. -12x^3 + 28x^2<= your answer</h2>
C. -12x^3 − 28
D. -12x^3 − 28x^2
The slope of the line is 50. You can try looking at the equation, which is
y=50x+500
500 is your y-intercept, and is where the cost starts.
50 is your slope, since the cost goes up by $50 every time.
x is how many hours, which determines how many $50s there are.
I hope this helps. All in all, the slope is 50.
