Charles paid $398.57 for a new computer. He knew that the total included about 28$ in tax. What is the approximate percentage of the total that was tax?

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 )

i believe it's a.

i'm not sure on this one, most likely correct.

good luck!

X= -5because this is a single step equation so you would just have to divide -16 both sides for x to equal your solution
