I am thinking of a five-digit number where the fifth digit is one-half the fourth digit and one-fourth the third digit. the thir

Natasha_Volkova [10]

solution:

Let the number be ABCDE

>>The second digit is three times the fourth digit<<

So D is 1,2, or 3 and B is 3,6 or 9.

The number is A3C1E, A6C2E, or A9C3E

>>The second digit is ... five more than the fifth digit.<<

That rules out 3 for B, so B is 6 or 9, and D is 2 or 3.

It also tells us that E is 1 or 4, so that B can be 5 more than it.

So the number is A6C21 or A9C34

>>The third digit is ... twice the fourth digit<<

So C is twice D, which is 2 or 3. So C is 4 or 6

So the number is A6421 or A9634

>>The third digit is one-half the first digit

So C is 4 because 6 is too large to be half a digit. And so

A has to be 8 so that C=4 can be half of it.

So the number is 86421.

Mr. duc asked to set up 450 chairs in a large hall. Perry puts 20 chairs in each row. He has already set up 15 rows of chairs

Each row consists of 20 chairs

He already set up 15 rows

So number of chairs he already set up = chairs in each row * number of rows

20 * 15 = 300

So , he already set up 300 chairs

Total chairs to set up is 450

Remaining chairs to set up = 450 - 300 = 150

So, 150 more chairs to set up

The average median income for a dentist is $142,740. The average median income for a medical and health service manager is $86,4

KiRa [710]

A: For the Dentist, their average income in 30 years is $4,282,200

B: For the Manager, their average income in 30 years is $2,592,000

C: The difference in both their earnings is $1,690,200

Work: So, I just multiplied their average earnings by 30, and that's what their average income will be in 30 years. For the difference, I subtracted the higher earning by the lower earning, and that's the difference.

I hope this helps you. :)
