Astar has a diameter of 4,680,000,000 units. express this number in scientific notation.

Step-by-step explanation:

Scientific notation is defined as a way of writing very large or very small numbers.

A number between 1 to 10 is written in scientific notation when it is multiplied by a power of 10.

Here the given scenario is :

A star has a diameter of 4,680,000,000 units.

So, in scientific notation we can write this as :

We can check this if we multiply this by 10^9. This will shift the decimal to 9 places in the right side.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

3x + 4y -25 =0 represents the amount of change sianna should recieve
