cluponka [151]

Answer

92%

Explanation

23 out of 25 people voted Abdul.

So that means $\frac{23}{25}$ people voted Abdul.

When you divide 23 by 25 you get 0.92 which is 92% (multiply by 100).

You divide because a fraction means the numerator divided by the denominator.

The ratio of the areas of two similar polygons is 400:25. what is the ratio of their corresponding sides

Bogdan [553]

The ratio of areas is given by:
A1 / A2 = 400/25 = k ^ 2
Therefore, the relationship of the sides is given by:
L1 / L2 = k
Clearing k we have:
k = root (400/25)
Rewriting we have:
L1 / L2 = k = 20/5
Answer:
The ratio of their corresponding sides is:
20: 5
