How many one pound coins would you need to make a line from land's End to John O'Groats?

Unknow I was looking for the bloody awnser


John has a total of 13 coins in his pocket Of the 13 coins they are all either quarters or dimes The total value of the coins is 2.50 How many quarters does John have in his pocket?

8 of them.


John has a total of 13 coins in his pocket Of the 13 coins they are all either quarters or dimes The total value of the coins is 250 How many dimes does John have in his pocket?

If all coins were dimes he would have $1.30. Every quarter that replaces a dime increases the total by 15c. The total has to be increased by $1.20 which is 15c x 8. He has 8 quarters and 5 dimes.


If John is twice as old as Mary then how old is Mary if John is 4?

Mary would be two years. This is a division problem 4 (John's age)/2 (two times older)=2(mary's age.)


John has a total of 13 coins in his pocket of the 13 coins thay are all either quarter or dimes the total value of the coins is 2.50 how many quarters does john have his pocket?

The first step in solving this problem is to build two equations. 0.25Q+0.10D=2.50 and Q+D=13 where Q=total number of quarters and D=total number of Dimes. Next we try to subtract one equation from the other to eliminate one variable. So we multiply 0.25Q+0.10D=2.50 by 4 to get 1Q+0.4D=10. Then we subtract Q+0.4D=10 from Q+D=13. This results in 0.6D=3. We divide both sides by 0.6 and end up with d=5. Therefore we have 5 dimes, which equals 50 cents. Therefore we have $2 in quarters or 8 quarters. 8 quarters is the answer.
