Answer: The value of x is 7.

Step-by-step explanation:-

Scientific notation is defined as the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.

For example : 5000 is written as 5.0\times 10^3

As we are given that the value is 28,500,000

This number is written in scientific notation as : 2.85\times 10^{7}

Therefore, the value of x comes out to be 7.

How do I make 24/9 into a mixed number
wlad13 [49]

U divide 24 to 9, which is not going to be an exact number, but you can do 9times2=18 so then if you do it in a long division bar you will put 2 on top then minus 18 from 24 which will give you 6, then ur answer is going to be 2 6/9 the nine stays the same (the denominator stay put)

ANSWER ASAP PLEASE

Answer:

Javier,16,12

Step-by-step explanation:

From the first bag, we can pull a 1,2 or 3.  That would go on the first line of the tree diagram

From the 2nd bag, we can draw a 4,5, or 6.  That goes on the the second line under each number

From the 3rd bag, we can draw a 7,8, or 9.  That goes on the the third line under each number

Javier drew the correct tree diagram.

1,3,5,7,9 are odd numbers.  We must have at least 2 of these numbers

1,4,7            2,5,7            3,4,7

1,4,9            2,5,9            3,4,9

1,5,7                                 3,5,7

1,5,8                                  3,5,8

1,5,9                                  3,5,9

1,6,7                                  3,6,7

1,6,9                                  3,6,9

There are 16 total where there are at least two odd numbers

Multiples of 4 are 4 and 8

We must have either a 4 or an 8 but not both

1,4,7             2,4,7         3,4,7

1,4,9            2,4,9          3,4,9

1,5,8            2,5,8          3,5,8

1,6,8            2,6,8          3,6,8

There are 12 outcomes
