Mr. Chang received the better discount

Step-by-step explanation:

Mrs. Robinson bought a novel at a bookstore on sale for 20% off its regular price of $29.99

The price of the novel at a bookstore = 29.99 -(20% × 29.99)

= 29.99 - (0.20 × 29.99)

= 29.99 - 5.998

= $23.99

Mr. Chang bought the same novel at a different bookstore for 10% off its regular price of $25.

The price of the novel at a different bookstore = 25 - (10% × 25)

= 25 - (0.10 × 25)

= 25 - 2.5

= $22.50

Mr. Chang bought the novel at the price of $22.50 and Mrs. Robinson bought the same novel at the price of $23.99.

Therefore, Mr. Chang received the better discount.

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 )
