This question is incomplete, the complete question is;
A household item uses 321 watts of electricity. This item is used for 27 hours each week. How much CO2 will be produced each week from this item? (assume 1.37 pounds of CO2 is produced per KWH of electricity used)
Answer: 11.87 lbs of CO2 will be produced each week from this item
Step-by-step explanation:
Given that;
Average wattage Wattage of the item = 321 watts
Time used = 27 hours each week
CO2 produced each week = ?
so;
Total electricity consume = 321 × 27 = 8667 watt = 8.667 kWh
given that; 1.37 pounds of CO2 is produced per KWH of electricity used
hence; CO2 generated by our item will be;
⇒ 8.667 kWh × 1.37
= 11.87 lbs
Therefore, 11.87 lbs of CO2 will be produced each week from this item

Answer:
Price increase $1,947
Price of the next model $34,947
Step-by-step explanation:
Since the next model of a sport car will cost 5.9% more than the current model, and the cost of current model is $33,000
The price increase in dollars would be;
= 5.9% × $33,000
= $1,947
The price of the next model would be;
= Cost of current model + Price increase
= $33,000 + $1,947
= $34,947
Answer:
We got less than 2 1/2 ft
Step-by-step explanation:
We need to add up all the snow on the three days
Monday = 15 inches
Tuesday = 4 1/2 inches
Wednesday =6 3/4 inches
------------
25 + 1/2 + 3/4 inches
Getting a common denominator
25 + 2/4+3/4
25 + 5/4 inches
25 + 1 + 1/4 inches
26 1/4 inches of snow
2 1/2 ft
1 ft = 12 inches
2 ft = 24 inches
1/2 ft = 6 inches
2 1/2 ft = 24+ 6 inches
= 30 inches
26 1/4 inches < 30 inches
We got less than 2 1/2 ft
