The house with 30000 cubic foot costs less to cool per cubic foot than the house with 25000 cubic foot.
Step-by-step explanation:
The cost of cooling 30000 cubic foot house = $7
Cost per cubic foot = 7/30000
=$0.00023
The cost of cooling 25000 cubic foot house= $6.50
Cost per cubic foot=6.50/25000
= $0.00026
The house with 30000 cubic foot costs less to cool per cubic foot than the house with 25000 cubic foot.
The area of the square is 81 sq in, and the area of the circule is (3.14)(3 in)^2, or approx 3.14(9) sq in, or approx 28.27 sq in.
Subtract: 81 sq in - 28.27 sq in = approx. 52.73 sq in.
The difference is 52.73 sq in; the square is larger, the circle smaller.
Well flat means open so 180°
180° - 50° = 130° is the answer
Answer:
6
Step-by-step explanation:
For a quick rough estimate, I'd round 9.1% up to 10% and 59.3 to 60. 10% of 60 is 0.1(60) = 6.
For a more accurate estimate, round 9.1% down to 9% and 59.3 up to 60. Then 9% of 60 is 5.4.
