Question 21: 24 minutes
x = 
x = 24
Question 22: 20 centimeters
x = one side of the square
x² = 25
x = 5
4x = perimeter
4(5) = perimeter
20 = perimeter
Question 23: 17 sides
Hexagon = 6 sides
Octagon = 8 sides
Triangle = 3 sides
Total amount of sides = 6 + 8 + 3
Total amount of sides = 17

So it starts by 22.50 regularly so she worked 40 regular hours so $22.50 * 40h= $900 and in over time she gets double for working over time so $22.50 * 2 = $45 and she worked 12 hours so 12h * $45 = $540 then we need to add those two numbers up 900 + $540 = $1,440 is our answer/outcome.
The answer is it’s 5 pie over 4
Answer:
800 mL
Step-by-step explanation:
Let b represent the amount of solution B added to 2400 mL of solution A. The total amount of alcohol (mL) in the mixture is ...
10%×2400 + 50%×b = 20%×(2400 +b)
multiplying by 100 to get rid of the % signs and simplifying, we have ...
24000 +50b = 48000 +20b
30b = 24000 . . . . . . . . . subtract 24000+20b
b = 800 . . . . . . . . . . . . . . divide by 30
Debra added 800 mL of 50% alcohol to her 2400 mL of 10% alcohol to make a 20% solution.
