Answer:
mCO₂ = 1.188 lb or simply 1.2 lb
Step-by-step explanation:
We need to use the following expression:
E = P * t
Where:
E: Energy in Kwh
P: Power in Watts
t: time in hours.
Applying this, with the given data we have:
E = 150 * 8
E = 1200 watts . h
Converting this value in kW we have:
E = 1200 watts * 1 kW/1000 watts = 1.2 kWh
In general terms, we have 0.99 pounds of CO₂ emissions per kWh, so with the obtained value we have:
mCO₂ = 0.99 * 1.2
<h2>
mCO₂ = 1.188 lb or simply 1.2 lb</h2>
Hope this helps
Answer:
-4,7
Step-by-step explanation:
add both to get y=7
then sub y in 2 to get 8x+42=10
8x=-32
x=-4
Step-by-step explanation:
the first one if you are solving for x it will be x=21-8y
if you are solving for y it will be y =21/8 - x/8
the second one will be if you are solving for x x = 2 -5y/3
solving for y is y=6/5-3x/5
