Answer:
What is the mission
Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
given that y varies directly with x
mathematically we can express this as
y = k x , where k is a constant
step 1: find k
given x = 3 and y = 21
y = k x
21 = k (3)
k = 7
hence the equation becomes
y = 7 x
when y = 105,
105 = 7x
x = 105 / 7 = 15
Volume=length times width times height
given
volume=576
length=12
width=6
height=?
576=12 times 6 times ?
576=72 times ?
divide both sides by 72
8=?
8 layers
