Answer:

Percent error = 15.79%

Step-by-step explanation:

Given the following data;

Experimental value = 12cm

Actual value = 14.25cm

To find the percentage error;

Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.

Mathematically, it is given by this expression;

Percent \; error = \frac {experimental \;value - actual \; value}{ actual \;value} *100

Substituting into the equation, we have;

Percent \; error = \frac {12 - 14.25}{14.25} *100

Percent \; error = \frac {2.25}{14.25} *100

Percent \; error = 0.1579 *100

Percent error = 15.79%

How do you solve<br> 25n=70
alisha [4.7K]
You want to do to one side the same thing you do to the other side.

In order to get the n by itself you divide the 25n by 25. But in order to not change the answer you need to do the same to the 70.

\frac{25n}{25} =  \frac{70}{25}

so n=\frac{70}{25} which can be reduced to \frac{14}{5}

so n=\frac{14}{5}
