Mr. wilson bought 4 tires for $390.60. if each tire cost $90 before tax was added. what tax rate did he pay on the tires?

First  calculate after tax tire price 
$390.60 / 4 = $97.65  after tax price per tire 
take the $97.65 divided by 90 
97.65 / 90 = 1.085 
1.085 is the rate of tax he paid per tire 

No because if you do the higher number minus the lower number you will get a positive. if you do it the other way around you will get a negative number

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
