<span>Given number is 41/50,
Now, let’s find which one is closer to the given choices:
=> 9/11
=> 10/11
Notice that the given number and given choices are fraction numbers. In order
know which one is closer to the given number, we need to convert these numbers
into a decimal.
Note, that in converting a fraction number to a decimal is we need to divide
our numerator by our denominator to get the answer.
=> 41/50
=> 0.82
The value of 41/50 is 0.82. Now, let’s find the value of the given choices.
=> 9/11
=> 0.818 or 0.82
=> 10/11
=>0.909 or 0.91
Thus, the correct answer is 9/11 is equals to 41/50.</span>
Answer:
25 Months
Step-by-step explanation:
Let's make the equations first,
Plan A: 70x Plan B: 50x+500...
Now we make it into an equivalent equation:
70x=50x+500...
Then we solve:
70x=50x+500-50x -50x20x=500...
÷20 ÷20x=25...
To check if it's correct, we just plug it in:
70(25)=50(25)+500...
1750=1750...

Answer: y = 2 <em>when x = 4</em>
i looked for a correlation in the given problem, and i realized that "y" will equal half of whatever "x" equals. so <em>when x = 4</em>, y = 2.
Answer:
The refrigerator was at around 13 ∘C
Step-by-step explanation:
Newton's Law of Cooling:
The rate of change of a body temperature (amount of heat loss/time of loss) is directly proportional to the difference between its own temperature and the surroundings.
T ⇒ temperature
t ⇒ time
Tenv ⇒refrigerator temperature
⇒ rate of change of he temperature
-h ⇒ constant of proportionality (negative because the temperature is decreasing inside the refrigerator)
We have 3 points:
time (minutes) - Temperature (∘ C)
0 (when the pan was put in the refrigerator) - 46
15 (after 15 minutes) - 27
30 (15 minutes after the first 15 minutes) - 19
= -h (27 - Tenv)
= -h (19 - Tenv)
Now we have a system of two equations and two variables
The refrigerator was at around 13 ∘C
