If the temperature drops, then you must have subtract amount of drop from initial temperature.

The correct answer is the first one.
Answer:
I got 40210.1
Step-by-step explanation:
4,567.89+7,894.56=12462.45
12462.45+1,232.45=13694.9
13694.9+1,474.10=15169
15169+2,585.20=17754.2
17754.2+3696.36=21450.56
21450.56+3,214.56=24665.12
24665.12+6,545.65=31210.77
31210.77+7,898.78=39109.55
39109.55+1.100.55=40210.1
Yes, it’s D because you would have want to compare both fractions by making them have the same denominator. Since 60 is the least common denominator for 10 and 12 (the denominators), you would convert the fractions by multiplying the numerator and denominator of 5/10 by 6 to get 60. 5/10 would turn into 30/60. Then you would multiply 6/12 both by 5, and then it would turn into 30/60. Now that you have equal fractions, you can guess that they are the same. Therefore, 30/60=30/60! An easier way of doing it would be just simplifying them into 1/2 and comparing them + seeing that they are both 1/2. Hope this helps!

Answer: 47°C
Step-by-step explanation:
Since we are given the velocity, all we have to do is plug in 358 for v and solve for t.
[divide both sides by 20]
[square both sides to cancel out square root]
[subtract both sides by 273]

Now that we know the temperature is 47.41°C, we know our answer choice is D.
