Answer:
The area of the tablecloth showing is approximately 45.55 square feet
Step-by-step explanation:
The diameter of the dinner table, D = 8 feet
The diameter of each plate, d = 1 feet
The number of people at the dinner table = 6 people
The number of plates = 6 plates
The area of the table cloth, A₁ = π·D²/4
∴ A₁ = π × 8²/4
The area covered by the 6 plates, A₂ = 6·π·d²/4
A₂ = 6 × π × 1²/4
Let 'A' represent the area of the tablecloth showing when the table is set for six people, we have;
A = A₁ - A₂
∴ A = π × 8²/4 - 6 × π × 1²/4 ≈ 45.55 ft.²
The area of the tablecloth showing when the table is set for six people, A ≈ 45.55 ft.²
Answer:
Looks good to me
Step-by-step explanation:
I checked for an incorrect answer and it seems like you got everything right :)
You need to distribute the 4, so you'll end up with:
4n-16=-12
Then, add 16 to both sides.
4n-16+16=-12+16
4n=4
Divide by 4 on both sides.
4/4n=4/4
n=1
No matter what units you are exchanging to and from, the number of unit cubes will remain constant. For example: If I had a cube who's side was 10 km long, the number of unit cubes would be the volume of the cube which in this case is 1000 km³. So there would be 1000 unit cubes. Then, if I changed the side from 10 km to 10 in, and find the volume, it would be 1000 in³, meaning there are 1000 unit cubes! So the answer to your question is: The number of unit cubes remains constant
