120-95=25, 25/2 = 12.5 weeks or 13 weeks if they want it rounded to a whole number
Answer:
Mathematics is never a challenge on my side.
Step-by-step explanation:
hope that will help you
I don't understand this work sorry.
As the general formular for a straight line is
m represents the gradient
c represents the point at which the line crosses the y axis.
Therefore you simply plug the numbers into the equation.
You can work out whether 2 lines are perpendicular by multiplying their gradients. The product of the gradient of perpendicular lines will always be -1.
If lines are perpendicular, M1× M2 = − 1
So you can rearrange the equation to get M2=-1/M1.
As they perpendicular they have to intercept at the same point on the Y axis therefore you get the equation
The diameter is 8, so the radius is 4 (cut the diameter in half)
r = 4
The height is h = 3
Plug this into the formula below which is the volume of a cylinder
V = pi*r^2*h
V = pi*4^2*3
V = pi*16*3
V = pi*48
V = 48pi <--- this is the exact volume in terms of pi
V = 48*3.14
V = 150.72 <---this is the approximate volume
V = 151 cubic cm is the approximate volume if we round to the nearest whole number
