Keeping in mind the rules for significant digits, what is the product of 0.8954 m and 2.98 m?

3.240576

Explanation:

There are various ways of doing multiplication this is one of them

The wording "keep in mind the rules for significant digits" implies that we are to use these to show where the decimal place goes by approximating the answer. Then conducting the exact calculation.

Consider 0.8 as 8

=

2.4

So the solution is some where a bit above 2.4

Lets just use the numbers

Multiply both 0.8439 and 3.84 by 1000 to get rid of the decimal place. This makes thing more straight forward. So we end up with:

8439

×

38400

Split up the 38400 into 30000+ 8000 + 400

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.
