Answer: 120
Step-by-step explanation:
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](https://tex.z-dn.net/?f=%20Percent%20%5C%3B%20error%20%3D%20%5Cfrac%20%7Bexperimental%20%5C%3Bvalue%20-%20actual%20%5C%3B%20value%7D%7B%20actual%20%5C%3Bvalue%7D%20%2A100)
Substituting into the equation, we have;
![Percent \; error = \frac {12 - 14.25}{14.25} *100](https://tex.z-dn.net/?f=%20Percent%20%5C%3B%20error%20%3D%20%5Cfrac%20%7B12%20-%2014.25%7D%7B14.25%7D%20%2A100)
![Percent \; error = \frac {2.25}{14.25} *100](https://tex.z-dn.net/?f=%20Percent%20%5C%3B%20error%20%3D%20%5Cfrac%20%7B2.25%7D%7B14.25%7D%20%2A100)
![Percent \; error = 0.1579 *100](https://tex.z-dn.net/?f=%20Percent%20%5C%3B%20error%20%3D%200.1579%20%2A100)
Percent error = 15.79%
Answer:
9
Step-by-step explanation:
9+9= 18
1.29 + (2.19 - 0.45) + 4.39 + 2.79 + 4.89 = 15.10
she only used 2 coupons...the one for eggs and the one for free bagels because she bought the bacon. So I took off 0.45 from the eggs, and the bagels were free because she bought the bacon.
Here is the formula
V= pi x radius (squared) x height
3.14 x 5 x 7 = 549.5
