Gas prices are up 30% since last year when they were $4.35, how much is gas now? Express your answer rounded correctly to the nearest cent.

$5.66/gal

Step-by-step explanation:

To calculate the current price of gas, multiply $4.35/gal by (1 + 0.30), or by 1.30:

1.30($4.35/gal) = $5.66/gal

step-by-step explanation: hi!

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.
