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:
slope is the rate at which a function progresses. y intercept a point that passes through they x axis when it is 0. ex) (0,9)
equation written as y=ax +b
b = y intercept
ax = slope
ax = y2-y1/x2-x1
take 2 random points
(0,3) (-2,0)
slope : 0-3/-2=0 = -3/-2 = 3/2
y intercept = 3 because x = 0 and y =3
<u>equation = y =3/2x + 3</u>

Answer:
15
Step-by-step explanation:
z2 - 2z + 15
(15)2 - 2(15) + 15
30 - 30 + 15
0 + 15
15
Answer:
<u>89.4</u>
Step-by-step explanation:
Okay well if 149=100% and there is a 40% we just have to find 60% and to do that we just multiply 149 by 0.60 to get 89.4
149*0.60=89.6
3a-7=-4b+1
3a-8=4b
(3a/4)-2=b
