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:
60%
Step-by-step explanation:
Given that Ben, Fran and Stan post funny memes online.
Benny got 40% more likes than Stans's
Fran got 20% fewer likes than Stan's
Let x % be that of Stan's
Then Ben's likes would be x+40 %
and Fran's likes would be x-20%
Difference = x+40-(x-20) = 60
Hence put to gether we can say that
Ben got 40-(-20) = 60% more likes than Fran
