Aiden measures a book with paper strips. it is actually 10 paper strips long, but he gets an answer of 8. what is his mistake ?

Since no options are provided, there could be several reasons for this.

Among these reasons are:

1- He did not measure from the beginning of the first strip till the end of the last one.

Now, check the attached picture please.

For the measurement to be correct, he should measure from the beginning of the first strip till the end of the last one as represented by the red line.

If he measured otherwise, say for example, from the end of the first strip till the beginning of the last as represented by the blue line, he will be getting the wrong measurement.

2- The strips may be of different width. This would lead to an error in measurement.

3- He might have simply miscounted the strips.

4- He did not follow the precision or accuracy rules stated for the measurements using paper strips (if they were stated)

Hope this helps :)

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
