The percentage of correct answers is 85% and the percentage of incorrect answers is 15% and this can be determined by using the unitary method.
Given :
- Henry takes a math test that had 20 questions.
- He answered 17 questions correctly and 3 questions incorrectly.
The following steps can be used in order to determine the percentage of correct and incorrect questions Henry answered:
Step 1 - The unitary method can be used in order to determine the percentage of correct and incorrect questions Henry answered.
Step 2 - The total number of questions in a math test is 20. The total number of correct answers is 17 and the total number of incorrect answers is 3.
Step 3 - If the 20 is the 100% questions then the percentage of 17 correct answers is:
= 85%
Step 4 - If the 20 is the 100% questions then the percentage of 3 incorrect answers is:
= 15%

If he buys 30 for x amount and sells them for y then you would take y and subtract 30x and your left with the answer = y-30x.
Problem 5
Apply the Law of Sines
s/sin(S) = r/sin(R)
s/sin(78) = 10/sin(48)
s = sin(78)*10/sin(48)
s = 13.162274
<h3>Answer: 13.162274 approximately</h3>
=============================================================
Problem 6
Use the Law of Sines here as well.
x/sin(X) = y/sin(Y)
x/sin(53) = 6/sin(22)
x = sin(53)*6/sin(22)
x = 12.791588
<h3>Answer: 12.791588 approximately</h3>
The number of bottles in the full box by solving the equation is 12.
<h3>How to form an equation?</h3>
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the number of bottles in the full box = x
Initial bottles = 9
Bottles in 3 full box = 3x
Bottles in 2 box in which number of bottles is x - 1 = 2(x-1)
Now,
Total bottles in refrigerator is 67
So,
9 + 3x + 2(x - 1) = 67
9 + 3x + 2x - 2 = 67
5x = 60
x = 12
Hence "The number of bottles in the full box by solving the equation is 12".
