Answer:20+10
Step-by-step explanation:It is 20 plus 10 because 6 times 5 is 30 and so is 20 plus 10.
The slope of this line is
−
12
5
.
Perpendicular lines have opposite reciprocal slopes. To find an opposite reciprocal, multiply by
−
1
and flip the numerator and denominator.
Hence the opposite reciprocal of
−
12
5
and the slope of a line perpendicular to a line with a slope of
−
12
5
is
5
12
.
The ratio is 5:1:3 as there is 25:5:15 which is all divisible by 5 making the simplest ratio in that order
3 days = 72 hours + 12 hours = 84 hours
12600 watt hours / 84 hours
= 150 watt hours / 1 hour
It’s asking how many watt hours consumed per day. We know 150 watt hours per hour so multiply that by 24 because 24 hours in a day
= 3600 watt hours per day
