Answer:
9
Step-by-step explanation:
The answer is A. 4
in this equation you use pythagoreans theorem
x^2-8^2=9^2
x^2-64=81
81-64=17
square x^2 square 17
x=4.12 rounded to 4
Volume of cylinders = pi x r^2 x height Simplifying the ratio: 1.6/3 = 16 / 30 (multiply and divide by 10 to remove the decimal) Volume Ratio = 512:27
To answer this item, we let x and y be the amounts (in mL) of the red and the brown dyes, respectively. The equations that would allow us to answer the question are,
x + y < 200
x ≤ 2y
The values of x and y in the inequalities are therefore 133.33 mL and 66.67 mL.
