Answer:
170 cm^2.
Step-by-step explanation:
This consists of 3 rectangles of same area and 2 triangles of the same area.
= 3 * 10 * 5 + 2 * 1/2 * 5 * 4
= 150 + 20
= 170 cm^2.
To round to the nearest ten million, check the millions digit after it:
2 , 0 2 4
The millions digit is 4, so you will round down to 0. All digits after this number will be converted to 0.
Rounded to the nearest ten million, the number becomes 2,020,000,000.
Answer:
4.61% increase (round up as needed)
Step-by-step explanation:
Subtract the smaller amount from the larger to find the dollar difference

Then divide the difference by the original amount

Answer:
Correct option: third one -> 12
Step-by-step explanation:
In a polygon with 'n' vertex, we can trace diagonals from one vertex to all vertices, except to the vertex chosen and the two adjacent vertices (because we would have sides and not diagonals), so we would have 'n - 3' diagonals.
If we have a polygon with 15 vertex, the number of diagonals from one vertex is 15 - 3 = 12.
Correct option: third one
