Answer:
Part A)
1) 
2)
Part B)
1) 
2)
Step-by-step explanation:
Part 1) x and y vary inversely and x=50 when y=5 find y when x=10 what is k?
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or 
step 1
<u>Find the value of k</u>
x=50 when y=5
substitute the values
------>
-----> 
The equation is equal to
or 
step 2
<u>Find y when x=10</u>
substitute the value of x in the equation and solve for y
Part B) x and y vary directly and x=6 when y=42 find k what is y when x=12
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form
or 
step 1
<u>Find the value of k</u>
x=6 when y=42
substitute the values
------>
----->
The equation is equal to
or
step 2
<u>Find y when x=12</u>
substitute the value of x in the equation and solve for y
Answer:
x = 37
Step-by-step explanation:
You just minus 5 from 42 lol

Answer:
V =648 mm^3
Step-by-step explanation:
The volume of a prism is given by
V = l*w*h
V = 6*9* 12
V =648 mm^3
