"A storage room must be kept at a temperature (T) such that triple the temperature is at least 15° C, but the temperature plus 8 is not more than 20° C. What is the range of safe temperatures?"
- A \([5 , 12)\)
- B \((5 , 12)\)
- C \([5 , 12]\)
- D \([5 , 20)\)
Answer & Solution
Correct Answer
(C) \([5 , 12]\)
Step-by-step Solution
Detailed explanation
From the given problem, the temperature \(T\) must satisfy two conditions. The first condition is that triple the temperature is at least \(15\). This can be written as the inequality: \(3T \ge 15\) Dividing both sides by \(3\) yields: \(T \ge 5\) The second condition is that…
