Answer:
SA of black base: 84 cm^2
SA of blue faces: 84 cm^2
SA of gold faces: 60.2 cm^2
SA of 1 ornament: 228.2 cm^2
SA of 100 ornaments: 22,820 cm^2
Step-by-step explanation:
SA of black base:
A = lw
A = 7(12)
A = 84 cm^2
SA of blue faces:
A = bh
(don't divide by 2 since there are 2 triangles)
A = 12(7)
A = 84 cm^2
SA of gold faces:
A = 7(8.6)
(don't divide by 2 since there are 2 triangles)
A = 60.2 cm^2
SA of 1 ornament:
Add #s in bold:
84 + 84 + 60.2 = 228.2 cm^2
SA of 100 ornaments:
Multiply SA of 1 ornament by 100:
228.2(100) = 22,820 cm^2
Answer:
angle A=30°
Step-by-step explanation:
Slope is 2/3. All of the letters equal the slope of 1.

Euclid
By Vicki Young
<span>Euclid dreamed of measuring stuff, many years ago.
He wrote down all the rules for us – a method he would show.
The world seemed flat back in his day,
But all his rules still hold today.
He called his math geometry –
it’s math for you and me.
It was geometry –
measure the earth, you see.
It’s math that’s real for me
- angles and symmetry.
Postulates still are true tell us just what to do.
This much I know is true
Geometry is the math I want to teach to you!
Through the years, they added more, with each new theorem found.
All those Greeks had found the door to prove the earth was round.
This math still rules the world today,
With all the shapes along our way.
This is the math, geometry – it’s math that you can see. </span></span>
The operation you would do first is 7*4 as according to PEMDAS.
PEMDAS stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction.
In the order of PEMDAS, you would do whatever expression is in the parentheses, and in this case it is 7*4.
