Ответ:
Space heater consumption (kWh) = 50 kWh
Explanation:
Given:
Total spending on electricity = $100 per month
Rate of electricity = $0.20 per kWh
Space heater consumption = 10% of total electricity
Find:
Space heater consumption (kWh)
Computation:
Total electricity consumption = $100 / 0.20
Total electricity consumption = 500 kWh
Space heater consumption (kWh) = [Total electricity consumption][10% of total electricity]
Space heater consumption (kWh) = [500][10%]
Space heater consumption (kWh) = 50 kWh
Ответ:
A.
Explanation:
The key word is simultaneously when it comes to parallel computing. Although the option could potentially be C, it's more likely to be A because it's "more right" in the words of my old English teacher. This is because A implies them working on it at the same time to reach the goal more effectively (another key word).
