Given:
surveyed 3/4 of the population
2/3 of the surveyed students are into school clubs or sports team.
Multiply the fractions:
1) Multiply numerators
2) Multiply denominators
3) Simplify fraction
3/4 * 2/3 = 3*2 / 4*3 = 6/12
6/12 can be simplified into 1/2
4a) 3 rows and 4 columns
4b) 2 of the rows gray
4c) 4 of the gray squares black
4d) 1/2 of the students participate in school clubs or sports team
Recall that all three angles in a triangle equals 180.
Knowing this, we just have to add up all the angles and figure out what the value 'x' is.
(x-22 + x-17 + 3x+19) = 180
Simplify:
5x - 20 = 180
Add 20 to both sides:
5x = 200
Divide both sides by 5:
x = 40
Now that we found the value for x, we need to solve for angle A.
Simply input the value of 'x' into angle A's equation:
40 - 22 = 18
Angle A = 18 degrees
Good luck! If you need me to explain anything, just ask :))

Answer:
Formula
1° × π/180 = 0.01745rad
Step-by-step explanation:
I'm pretty sure the answer is D. because I don't think anyone would want to take their total meal cost and then multiply it by their tip to make it even larger. You would just add the tip to the meal cost.
