The value of x varies directly with y and inversely with z. when x=4,and y=12, z=6. what is the value of k? A. K=6
B. K=2
C. K=18
D. K=288

B

Step-by-step explanation:

Given x varies directly with y and inversely with z then the equation relating them is

x = ← k is the constant of variation

To find k use the condition when x = 4 and y = 12, z = 6 , then

4 = ( multiply both sides by 6 )

24 = 12k ( divide both sides by 12 )

2 = k → B

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.

m∠a is 90°

m∠b is 40°
