Step-by-step explanation:
12 cm,
Simply use Pythagora's theorem. The square of the hypotenuse = the sum of the squares of the other two sides
So, you get the square of the missing side by subtracting 5 squared from 13 squared, which gives 144.
Square root of 144 is the length of the missing side, i.e. 12 cm.
9.5% of 500 = 47.5
9.5% × 500 =
(9.5 ÷ 100) × 500 =
(9.5 × 500) ÷ 100 =
4,750 ÷ 100 =
47.5;
