Answer:
16 - Original number of chocolates in the box.
Step-by-step explanation:
C = 6 / (3/8) =6 x (8/3) =48 / 3 = 16
<h2>○=> <u>Correct option</u> :</h2><h2>

</h2><h3>○=> <u>Steps to derive correct option</u> :</h3>
We know that :

So, let the diameter of this circle be x.
Which means :





Thus, the radius of the circle Robert drew = 6 m
Since the circle in option B has a radius of 6 m, it is the circle Robert drew.
▪︎<em>Therefore, the correct option is (B)</em>
The subtraction function

is defined as the subtraction of the two equations, representing each function:

So, we have

Answer:
- <em><u>12 tickets</u></em>
Explanation:
You must assume that the ratio of the number of tickets in row 7 is a constant.
That permits you to set a proportion with the ratio of the number of tickets in row 7 for the first batch of tickets and the ratio of the number of tickets in row 7 for the next 33 tickets sent out:
<u>1. Ratio of number of tickets in row 7 for the first batch.</u>
- Number of tickets in row 7: 20
- Total number of tickets: 20 + 19 + 16 = 55
- Ratio: 20/55
<u>2. Ratio of number of tickets in row 7 in the next 33 tickets sent out:</u>
- Number of tickets in row 7: x
- Total number of tickets sent out: 33
- Ratio: x/33
<u>3. Proportion</u>
Set the proportion and solve for x:

Answer: 12 tickets
