The distance from the earth to the sun is approximately 93,000,000 How is this distance expressed in scientific notation? SHOW YOUR WORK

Answers

9.3  ×  10 ^7

Explanation:

The decimal point is to the right of the last zero, so move it left until you get in between  9  and  3 , so there is only one digit to the left.  That's 7  spaces, so the answer is  9.3  ×  10 ^7 .

Step-by-step explanation:

Answer: 9.3 to 10 to the 7th power.

93,000,000 divided by 10 to the 7th is 9.3. So, 93,000,000 in scientific notation would be 9.3 × 10 to the 7th. You have to move the decimal point from 93,000,000 a trick for this is to count the zeros and divide by ten a calculator would make this easier. I hope I helped.

A bus can hold 40 passengers. How many buses will be needed for 170 passengers?

Answers

Answer:

Between 4 and 5

Step-by-step explanation:

You will need 5 buses to fit all 170 passengers
This is because 170 divided by 40 equals 4 remainder 10, and you can’t leave the 10 remaining passengers, so you’ll need a 5th bus, but it just won’t be full.

Answer:

c:-$12

Step-by-step explanation:

34+30=64.

then 64 - 76=-12

Answer:

-12

Step-by-step explanation:

You start off with $34 so +34

Then you spend $76 so -76

Then you deposit $30 so +30

There are several ways to go about this but i find the easiest way is to add the positives first.

We're going to say 34+30=64

Next we subtract 76 from 64= -12

You go about this in the same way you would if it didn't have a negative sign in front of it. Then since the 76 is the larger number you add the negative sign.  

  -76

-   64

-----------

  -12
