What is 102.831853072 as an estimated number?

103

Step-by-step explanation:

To estimate a value you need to add 1 to the value each time a value after the value is above 5. For example the question above

102.831853072

Let's start from 2 the last number

Less than 5 so you won't be adding one to the number before it

It becomes 102.83185307

The next number is 7 it is greater than 5 so you add 1 to the number before it. Then it becomes

102.8318531. Continue like this till you get to 8 after the decimal point.

8 is above 5 so add to 102 making 103.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
