guys need asap with these two problems

Question1: 58660

Question 3: 7244

Step-by-step explanation:

Question 1: My 5 is worth 50,000 means the number will start with 5 and will be between 50,000 and 60,000, thus will have 5 digits in total

My 8 is worth 8,000 means the next number is 8

One of my 6s is worth 60 means there is more than one 6. One 6 is worth 60 and the other is 10times as much so 600. The other digit is a 0. So those 3 together are 660.

The entire number is 58660

Question 3: The number has 4 digits:

My 7 is worth 7000 so the number will be between 7,000 and 8,000.

My 2 is worth 200 so.

One of my 4s is worth 40. So this means there is another 4.

The other number is 1/10 of 40, which is 4.

The total is 7244

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
