The change in the water temperature of a bottle of water when it dropped by 4 degrees every hour is 48 degrees
<h3>What is temperature?</h3>
Temperature can be defined as the hotness or coldness of a thing or place.
To calculate the change in water temperature after 12 hours, we use the formula below.
Formula:
- ΔT₁₂ = 12t'................ Equation 1
Where:
- ΔT₁₂ = Change in the water temperature after 12 hours
- t' = drop in temperature per hour
From the question,
⇒ Given:
Substitute into equation 1
- ΔT₁₂ = 12×4
- ΔT₁₂ = 48 degrees
Hence, the change in the water temperature is 48 degrees

Answer:
64
Step-by-step explanation:
To complete the square
add ( half the coefficient of the b- term )² to b² + 16b
b² + 2(8)b + 8²
= b² + 16b + 64 = (b + 8)²
Answer:
A.
Step-by-step explanation:
Sets A and C have a mode of 12 and a median of 12.
Calculate the means:
Set A: Mean = (8+10+12+12+14+16 ) / 6 = 12
Set C: Mean = (6 + 6 +12+12+18+24 ) / 6 = 13
So the required set is A.
Answer:
5
Step-by-step explanation:
Whenever you multiply square roots that have the same number inside the radicand, you get the number under the radicand. For example, the square root of 4 squared will equal four. Similarly, you are simply squaring the square root of 5, so you should get 5 as your answer.
