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

In this question, we have to convert 12m/s to km/min .
And for the conversion, we need km in the numerator and min in the denominator .
And 1 km equals to 1000 m and 60 seconds equals to 1 minute .
And that's the required conversion factor to convert 12m/s to km/min.
And hence out of the four given options, correct options are A and B .
Yes, we claim that the two ratios are proportional.
<h3>Proportion</h3>
Proportion is an equality between two ratios. These ratios are made up of two real integers. In a proportion, when there is an equality, both ratios have to be equivalent to the other. Equivalent ratio is when both division results are equal.
— To find out if the equality between these two given ratios is true, let's just: divide the numerator by the denominator.
3/8 = 3 ÷ 8 = <u>0,375</u>
24/64 = 24 ÷ 64 = <u>0,375</u>
Therefore, we see that the results of these ratios are the same. So these two ratios are proportional. 3/8 = 24/64
Answer:
y=3x
Step-by-step explanation:
3 is telling how many centimeter she knits per NIGHT, so x will be perfect for 3 because x will be the number of night. Y will be the answer because 3x will show the total length of the knit
