In ΔCAD and ΔCBD,

CD = CD [ Common side ]

AD = BD [ CD is the perpendicular "bisector" of AB ]

∠CDA = ∠CDB [ CD is the "perpendicular" bisector of AB ]

Thus, ΔCAD and ΔCBD are congruent triangles. [ SAS congruency ]

If these triangles are congruent, then AC = BC.

2x = 3x -10

x = 10.

6. For a particular pickup truck, the percent markup is known to be 115% based on cost to the seller. If the seller paid $15,800
Neko [114]

Answer:

  • <u>53.5 %</u>

Explanation:

You can convert the percent markup into a multiplicative factor in this way:

Base price:                     15,800 . . . (cost to the seller)

Percent mark up:           115% . . .  (based on the cost to the seller)

Sale price:                      15,800 + 115% of x = 15,800 + 115 × 15,800 /100 =

                                        = 15,800 + 1.15 × 15,800 = 15,800 (2.15) = 33,970

The markup is:

  • Markup = price paid by the seller - cost to the seller = 33,970 - 15,800   = 18,170 (notice that this is 115% of 15,800)

And <em>the percent markup based on the sale price is</em>:

  • % = (markup / sale price) × 100 = (18,700 / 33,970) × 100 =

            = 53.49 %

Rounding to the nearest tenth percent that is 53.5 %.
