Answer:

10%

Step-by-step explanation:

In this question, we are asked to calculate the percentage error in a measurement.

This can be obtained by first getting the error involved. That is calculated by Subtracting the value calculated from the actual value. That is 9.5 - 8.9 = 0.6

The percentage error is thus 0.6/9.5 * 100 = 6%

The value is actually 10% to the nearest tenth of a percent

jeyben [28]

Answer:

It will take 3.2 hours for 8 inches of snow to fall.

Step-by-step explanation:

You can solve this be going "backwards".

You have 2.5 inches of snow falling per hour for x hours until you get 8 inches of snow, which can be represented like this:

2.5x=8  From here you being to solve by isolating x on one side of the equation. You would divide both sides by 2.5 to do this

2.5x=8

/2.5    /2.5

8 divided by 2.5 is 3.2 and you then get

x=3.2

It takes 3.2 hours for 8 inches of snow to fall
