9. Denise measured the length of her
yard to be 90 feet. The actual length is

percent of error in her measurement?​

Respuesta :

There is 4.65% error in Denise's measurement.

Step-by-step explanation:

Given,

Length measured by Denise = 90 feet

Actual length = 86 feet

Percent error = [tex]\frac{|Approx-exact|}{exact}*100[/tex]

[tex]Percent\ error=\frac{|90-86|}{86}*100\\\\Percent\ error=\frac{|4|}{86}*100\\\\Percent\ error=\frac{400}{86} \\\\ Percent\ error =4.65\%[/tex]

There is 4.65% error in Denise's measurement.
