Nellie is buying bird seed to put in her bird feeders. She uses about 10 pounds of bird seed each week, but has room to store any extra that she purchases. The bird seed comes in 3 different sizes as given below:3.5 pounds for $2.527.5 pounds for $5.4011 pounds for $7.92Nellie is trying to be a smart shopper and get the best deal on the bird seed. Which size bag of bird seed should Nellie buy?a. Nellie should buy the 3.5 pound bags because they have the cheapest unit price b. Nellie should buy the 7.5 pound bags because they have the cheapest unit price c. Nellie should buy the 11 pound bags because they have the cheapest unit price. d. Nellie should buy any size she wishes because they all have the same unit price.

Divide the price by the weight of all three to get the unit price then compare them. The lower unit cost is the best deal.

2.52 / 3.5 = 0.72 per pound

5.40 / 7.5 = 0.72 per pound

7.92 / 11 = 0.72 per pound.

They are all the same so she can buy whatever one she wants.

The answer is

d. Nellie should buy any size she wishes because they all have the same unit price.

step-by-step explanation:

save it by not spending on unnecessary stuff and have more

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.
