Each week, mrs mack buys exactly 3 5/8

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.

- 4, v72, 32/5

i think this is right.

hope it

answer: victoria's daughter's cookie recipe uses less flour

step-by-step explanation:

you could set up a proportion (even though they are not equal) to find that the number of grams of butter used by victoria's daughter is twice as much, but the amount of grams of flour used are not (multiplied by 1.6 instead of 2)
