Jeanne makes hair bows to sell at the craft fair each bow requires .5 yards of ribbon at the fabric store ribbon is sold by foot if jeanne wants to buy 84 bows how many feet of ribbon must she buy

Hi there!

First off you need to know that 1 yard is equal to 3 feet.

In order to know how many feet each bow requires, you'll need to use the cross product method :

1 yard = 3 feet

0.5 yard = x feet

(3 × 0.5) ÷ 1 = x feet

1.5 ÷ 1 = x feet

1.5 = x feet

Since now you know that one bow requires 1.5 feet of fabric and you want to know how many feet of ribbon Jeanne must by to make 84 bows, you can use again the cross product method, or you can just multiply the amout of fabric required for one bow (1.5) by the number of bow you want to make (84) :

1.5 × 84 = 126

The answer is: Jeanne must buy 126 feet of fabric in order to make 84 bows.

There you go! I really hope this helped, if there's anything just let me know! :)

step-by-step explanation:

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.
