Answer:
Relation between V and c is represented as:

When c is halved, V becomes
of its initial value.
Step-by-step explanation:
Height of cylinder = Radius of cylinder = c
Volume of cylinder = V
As per formula:

Where
is the radius of cylinder and
is the height of cylinder
Putting 

The values of c is halved:
Using equation (1), New volume:

By equation (1), putting 

So, when c is halved, V becomes
of its initial value.
Answer:
-8 = d
Step-by-step explanation:
-10 = -2+d
Add 2 to each side
-10 +2 = -2+2 +d
-8 = d
Answer:
3.75Km
Step-by-step explanation:
to find Average speed you do distance over time so it would be 225/25=3.75
Answer:
y= 1/2x-3
Step-by-step explanation:
2y - x = 8
First find the slope
2y = x+8
Divide by 2
2y/2 = x/2 +8/2
y = 1/2 x +4
The slope is 1/2 ( y=mx+b where m is the slope and b is the y intercept)
When lines are parallel they have the same slope)
Using y = mx+b
y =1/2x+b
Substituting the point (4,-1) into the equation
-1 =1/2(4)+b
-1 = 2+b
-3 =b
The equation of the line is
y= 1/2x-3
C. y coordinates equal the gas pack
