Hello!
Divide the amount of chairs (30) that 12 people can build by the number of hours (8) it takes to build them, to find out how many chairs they make per hour.
30 ÷ 8 = 3.75
This means that they make they make 3.75 chairs per hour. Multiply this by 100 hours.
3.75 × 100 = 375
ANSWER:
The people can build D. 375 chairs in 100 hours.
The answer is 3/6.
So we know that 2/4 is equivalent to 1/2. 1/2 of 6 is 3. We can make this our numerator and our denominator as 6.
Using proportions, considering the total number of students, it is found that 216 boys to linking their school lunch.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, 400 - 152 = 248 boys were surveyed. 32 said they liked the school lunch and 248 - 32 = 216 said no liking their school lunch.

Let z = sin(x).
.. z^2 -2z = 2
.. z^2 -2z +1 = 3
.. (z -1)² = 3
.. z -1 = ±√3
.. z = 1 -√3 . . . . . the positive solution is extraneous
sin(x) = 1 -√3
