Answer:
Step-by-step explanation:
A, B and C must be real numbers, and A and B are not both zero (which would cause division by zero in the calculation of the slope).

This is a matter of elimination. So let's figure out how many of each display there is.
30% of 150 = 0.30 * 150 = 45 displays about electricity.
2/5 * 150 = 0.40 * 150 = 60 displays about renewable energy
1/10 * 150 = 150/10 = 15 displays about gas.
The rest of the displays are about nuclear power. So
150 - 45 - 60 - 15 = 30 displays about nuclear power. Since we want a fraction, we get 30/150
But 30/150 isn't in it's simplest form. The largest number that will evenly divide both 30 and 150 is 30. So divide both the numerator and denominator by 30
(30/30)/(150/30) = 1/5
So 1/5 of the displays are about nuclear power.</span>

Step-by-step explanation:
Answer: 10.3 pounds of CO2 is produced
Step-by-step explanation:
Assuming there are 30 days in a month, if the microwave is run for 10 minutes per day, then the number of minutes for which the microwave is run in a month is
30 × 10 = 300 minutes
We would convert from minutes to hours
60 minutes = 1 hour
Therefore,
300 minutes = 300/60 = 5 hours
Also,
1000 watts = 1 kW
Therefore,
1500 watts = 1500/100 = 1.5kw
Therefore, the number of kWh is
1.5 × 5 = 7.5 kWh
If 1.37 pounds CO2 per kWh, then
If 1kWh = 1.37 pounds CO2, then
7.5 kWh = 7.5 × 1.37 = 10.3 pounds rounded to the nearest tenth
