The distance from mercury to the sun is 28.5 million miles. the distance from neptune from the sun is 2.8 billion miles. express the distance between mercury and neptune in scientific notation

2.7715 x 10^9 miles

Step-by-step explanation:

The distance from Mercury to the sun is 28.5 million miles which is 28.5 x 10^6 miles.

The distance from Neptune to the sun is 2.8 x 10^9 miles.

Then we know that:

Distance Neptune-Sun = Distance Neptune-Mercury + Distance Mercury-Sun

Solving for 'Distance Neptune-Mercury" we have that:

Distance Neptune-Mercury = Distance Neptune-Sun - Distance Mercury-Sun

Distance Neptune-Mercury = 2.8 x 10^9 miles - 28.5 x 10^6 miles.

Distance Neptune-Mercury = 2,771,500,000 miles

Which can be expressed: 2.7715 x 10^9

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
