vazorg [7]

Answer

Find out the what is the percent error in the measurement, to the nearest tenth of a percent .  

To prove

Formula

Percentage\ error = \frac{error\times 100}{exact}

Where error = | Approx - Exact |

As given

Karen measures the width of a garden plot and records that it is 44.25 meters. Its actual width is 45.5 meters.

Approx value = 44.25 meters    

Actual value = 45.5 meters        

error = | 44.25 - 45.5 |

         = |-1.25|

         = 1.25

Put in the formula

Percentage\ error = \frac{1.25\times 100}{45.5}

Percentage\ error = \frac{125}{45.5}

Percentage error = 2.7%

Therefore the percentage error is 2.7% .

0.5 is 30 minutes how do I work out more times e.g. How many minutes is 0.45 or 0.48 I don't know how to do it help
kompoz [17]
I dont know if this will help you, but a 15th (.15) of an hour is 9 minutes!
So it'd be
.15=9 minutes
.30=18 minutes
.45=27
.60=36
.75=45 
.90=54
and obviously
1.0 is 60 minutes
(((EVERY .05 IS THREE MINUTES))))
