Answer:
Step-by-step explanation: The answer is 0.5
So a hack is we know that 20% times 5 =100% and 40 divided by 2=20 so
50=40%
divide both sides by 2
25=20%
20 times 5=100 so
multiply both sides by 5
125=100%

<h2>
Answer:The number of milk chocolates are 18 and the number of dark chocolates are 24.</h2>
Step-by-step explanation:
Let the number of milk chocolates be 
.
Let the number of dark chocolates be 
.
Given that the box contains the milk and dark chocolates in the ratio 
.
So,
...(i)
Given that the total number of chocolates are 
.
So,
. ...(ii)
Using (i) and (ii),
So,the number of milk chocolates are 
and the number of dark chocolates are 
.
12.7
Using the Pythagorean theorem, you can easily calculate the length of BC.
So:
BC = sqrt(12^2 - 6^2) = sqrt(144 - 36) = sqrt(108) = 10.39230485
Now consider triangle BCD. You know all three angles and one side. Using the law of sines you know that ratio of the sine of each angle over the opposite side is constant. So:
BC/sin(55) = CD/sin(90)
BC/sin(55) = CD/sin(90)
sin(90)BC/sin(55) = CD
1*BC/sin(55) = CD
BC/sin(55) = CD
10.39230485/0.819152044 = CD
12.68666167 = CD
12.7 = CD
