A toy car is placed at 0 on a number line. It moves 9 cm to the left, then 4 cm to the right, and then 6 cm to the left. The total distance the toy car traveled is cm.

19cm    

Explanation:

Total distance is the length of path covered by a body. It is different from displacement which is concerned with the start and finishing of a journey;

Given;

   From 0 mark

              9cm to the left

              4cm to the right

              6cm to the left      

                                                        0

                                                      start

                                  - - - - - - - - -

                                         9cm left

                                 - - - -

                                 4cm  right

                   - - - - - -      

                     6cm   left

Total distance  = 9cm + 4cm + 6cm  = 19cm              

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
