Answer:

3. A quadrilateral with each side length 4 cm

Step-by-step explanation:

We need to understand what is a unique polygon?

<em>It means all regular polygons with the same number of sides are similar.</em>

1.A triangle with angles 30 degrees, 60 degrees, and 90 degrees

It is an right triangle, so the 3 sides are not simillar, so it is wrong

2. A triangle with side lengths 5 cm, 4 cm, and 3 cm

It is a triangle with the 3 sides are not simillar, so it is wrong

3. A quadrilateral with each side length 4 cm

It is an square with the 4 sides are simillar, so it is true

4. A triangle with side lengths 7 cm and 8 cm and a 40-degree angle

It is a triangle with the 3 sides are not simillar, so it is wrong

Hence, we choose 3.

The school band sold cupcakes to raise money for new uniforms each of the 40 band members baked cupcakes to sell they either bak
Volgvan

This question is incomplete. Here is the complete question below:

The school band sold cupcakes to raise money for new uniforms. Each of the 40 band members baked cupcakes to sell. They either baked chocolate or vanilla cupcakes.

Each student baked 24 cupcakes.

Each cupcake was sold for $2.

All of the cupcakes were sold.

A total of $1,200 was earned from the vanilla cupcakes.

How much did the band earn from the chocolate cupcakes?

Answer: $720 was earned from the sale of chocolate cupcakes.

Step-by-step explanation:

Taking key points from the question:

*** 40 band members baked chocolate or vanilla cupcakes.

*** Each student baked 24 cupcakes

***Each cupcake was sold for $2

***All cupcakes were sold.

***$1200 was earned from the vanilla cupcakes.

Now, before we can determine how much was earned from y chocolate cupcakes sold, we must find out how many cupcakes were baked and later sold altogether.

Since a single studi baked 24 cupcakes and all members of the bani (numbering 40) baked cupcakes, then :

24 × 40 = 960 cupcakes.

Therefore 960 cupcu were baked altogether by the members of the band.

Again, since a single cupcake (irrespective of the flavour) was sold for $2, then:

$2 × 960 = $1920 was the total amount earned after selling all the cupcakes.

Then, if $1,200 was earned from the vanilla cupcakes, we can calculate the amount earned for selling chocolate cupcakes by subtracting the amount realized after selling all the baked vanilla cupcakes from the total amount earned after selling all cupcakes:

$1,920 - $1,200

= $720

Therefore $720 was earned after selling chocolate cupcakes.
