Answer:
1 hour and 6 minutes
Step-by-step explanation:
- A temperature difference of 58-40 = 18°F was obtained in 2 hours
- A temperature difference of 68-40 = 28°F will be obtained in x hours
The next proportion must be satisfied:
18 °F / 28 °F = 2 hours / x hours
x = 2*28/18
x = 3.1 hours in total
Given that she has already waited 2 hours, she must wait 3.1 - 2 = 1.1 extra hours. 1 hour is equivalent to 60 minutes, then 0.1 hours is equivalent to 0.1*60 = 6 minutes.
Answer:
Step-by-step explanation:
So we want to simplify:
Note that this is in the format:
And we know that this is the same as:
Let 2√5 be a and let √3 be b. Thus:
Simplify:
And this cannot be simplified any further.
I think the fraction in simple form is 25/8
Given :
Two numbers 25 and 17.
How much larger is the sum of the numbers 25 and 17 compared to their difference? (Two small brackets will be used.)
To Find :
How much larger is the sum of the given numbers as compared to their difference.
Solution :
Sum of given numbers, S = 25 + 17 = 42 .
Difference of given numbers, D = 25 - 17 = 8 .
The difference between S and D is, S - D = 42 - 8 = 34 .
Therefore, sum of the numbers is larger by 34 than in difference.
