Answer:
During cool or cold weather episodes, fuel must be consumed to make buildings comfortable living spaces. A useful indicator of fuel consumption for heating purposes is the determination of heating degree-days. They are calculated by accumulating one heating degree-day (HDD) unit for each Fahrenheit degree the daily mean (average) temperature is below the base value of 65°F (18°C). For example, a day with a maximum temperature of 60°F and a minimum of 40°F has a mean temperature of 50°F. Subtracting 50 from 65 yields 15 heating degree-day units for that day. Hence, a day with a high temperature of 45°F and a low of 25°F produces ______ HDDs.
Answer:
yes
Step-by-step explanation:
the numbers are going up
Answer:
this is not the answer thanks
We write the equation that is given above,<span>
45x + 50y = 25000
Since there are no women, x should be zero. We are then left
with the equation,
50y = 25000
<span>To answer, we divide both sides of the equation by 50 giving
us 50. Thus, Javier needs 50 male customers for him to meet his expenses. </span></span>
