Answer:

6 plus 4 = 10

6 plus 3 = 9

6 plus 4 plus 1 = 11

Step-by-step explanation:

Since it says use them exactly once does that mean once in each number answer or once in all 3

PART 1: Find the surface area of each section.

The formula for finding the area of a triangle is A = 1/2(b)(h); where b = base length and h = height. And the formula for finding the area of a rectangle is A = (l)(w); where l = length and w = width.

I'll start with the gold triangles, which are both the same size so I only need to calculate once.

A = 1/2(b)(h)

A = 1/2(7)(8.6)

A = 1/2(60.2)

A = 30.1 cm²

Now, I'll find the area of the blue triangles.

A = 1/2(b)(h)

A = 1/2(12)(7)

A = 1/2(84)

A = 42 cm²

Now, I'll find the area of the rectangular base.

A = (l)(w)

A = (12)(7)

A = 84 cm²

PART 2: Find the amount of foil in each color needed to cover 1 ornament.

There are two gold triangles, so all we have to do is multiply the area of the gold triangle by 2.

(30.1)(2) = 60.2 cm²

There are two blue triangles, so all we have to do it multiply the area of the blue triangle by 2.

(42)(2) = 84 cm²

And Olga will need 84 cm² of black foil to cover the rectangular base.

PART 3: Find the total amount of foil needed to cover 1 ornament and then 100 ornaments.

To find the total amount of foil needed, just add the amounts found in the previous step.

60.2 + 84 + 84 = 228.2 cm²

Olga will need 228.2 cm² of foil to cover 1 ornament.

(228.2)(100) = 22820 cm²

Olga will need 22, 820 cm² of foil to cover 100 ornaments.

PART 4: Fill in the blanks to give your answer.

Surface area of black face(s) = 84 cm²

Surface area of blue face(s) = 84 cm²

Surface area of gold face(s) = 60.2 cm²

Total surface area of 1 ornament = 228.2 cm²

Total surface area of 100 ornaments = 22, 820 cm²

Hope this helps!

Identify the property used in Step 3.

svp [43]

The associative property has been used in step 3

Step-by-step explanation:

There are multiple properties that are used to solve the equations

One of them is associative property.

Associative property states that the order of three terms which are being added doesn't matter the result will be same.

$a + (b+c) = (a+b)+c$

In step 2:

$2 + 2x + 10 + (-10 + 11x)$

As we can see that the last three terms are being added

The solver has used the associative property to solve the expression.

$2 + 2x + [10 + (-10)] + 11x$

The brackets have been changed from $10+(-10+11x)\ to\ [10 + (-10)} +11x$ using associative property

The associative property has been used in step 3
