If you mean you get them by diving them by 100 or something over 100(as in a fraction) that's the answer, I'm incredibly sorry if it is not what you meant!
Angle R - Apex
Just took the quiz, the answer was Angle R.
Hope this helps people in the future
We know that the line is tangent at the point (2,8)
The derivative of the function at x=2 is

So, the tangent line passes through the point (2,8) and has slope 2. The equation is

This line crosses the x axis where y=0:

From the information given, Dairon already had a string that is 4 7/8 inches long.
We first write or simplify 3/8 and 4 7/8 in their decimal fraction forms.
3/8 is written as 0.375 and 4 7/8 is written as 4.875
We can now find out how many pieces he cut from the string (that was 4 7/8 inches), so:
4.875 ÷ 0.375 = 13
So he got 13 pieces of string. He wants 20 pieces, so;
20 -13 = 7
Therefore he will need 7 more strings .
