Wallace received a 28 percent discount on an item priced at $275. what is the total price that he paid for it? cost after discount = price × (1 – discount percentage)

$198

Step-by-step explanation:

Given: The discount percentage : 28 % =0.28

The price of item = $275

The given formula for total cost of item after discount :

Substitute the value of price =$275 and discount percent = 0.28 in the above formula , we get

Hence, he paid the total price of $198 for it.

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.

the answer is
