Which of the following uses estimation to check 267 - 154 = 113 a. 300 - 150 = 150 b. 300 - 200 = 100 c. 270 - 150 = 267 d. 113 + 154 = 267

Option 'B'.

Step-by-step explanation:

Option 'A' and 'B' use estimation to check 267 - 154 = 113.

Option 'C' is wrong given that 270 - 150 is not 267. Also, option 'D' is not providing an estimation, just adding random numbers.

In the first case, option 'A', the number '267' is rounded to 300 which is the nearest multiple of 100. And the number '154' is rounded to 150 which is the nearest multiple of 50.

In the second case, option 'B', the number '267' is rounded to 300 which is the nearest multiple of 100. And the number '154' is rounded to 200 which is the nearest multiple of 100.

If you are to give one option, then the correct option would be option 'B', given that both options are rounded to the nearest multiple of 100, and the percentage of error is lower that the other options.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

yes because they have the same amount of green and blur marbles.
