Answer: 28 pairs
Step-by-step explanation:
12 times 5 is 60, so she has 60 pairs in total. She gives 32 pairs to one son, so 60-32 is 28. The other son receives 28 pairs of socks.
Hello!
I am happy to see your question posted here on Brainly. Let me see if I can help.
So I’m assuming you are wanting to know the new price of the car after the 12% is added.
Let’s get to work.
So what we want to do here is use addition.
33,600 + 12% = 37,632
And that is your answer! $37,632 is the new price of the car.
Have a wonderful day and thank you for using Brainly!

Answer:
174 rpm
Step-by-step explanation:
The question says that the speed is inversely proportional to the length. Thus, Inverse means, as the diameter increases, the speed reduces, or as the diameter reduces, the speed increases.
Thus, from the question, if diameter A is 20, and B is 10, then definitely, the speed will increase from 348 to a higher rate. Mathematically, we have
20 / 10 = 348 / x, where x is the missing speed.
2 = 348 / x
x = 348 / 2
x = 174 rpm
Therefore, the pulley A must have been running at a speed of 174 rpm
