Step-by-step explanation:

 The volume of a cone can be derived by writing an expression that represents the volume of one cone within the cylinder.

the expression for the volume of a cylinder is

volume-of-cylinder= \pi r^2h

the volume of a cone is a part of the volume of a cylinder

volume-of-cone= \frac{1}{3} \pi r^2h

Hence the volume of a cone can be derived by dividing the volume of a cylinder by 3

a lever will balance if the mass of object 1 times its distance from the fulcrum equals the ma's of object 2 times its distance
Afina-wow [57]

If the distance between the fulcrum and the effort is increased, the distance that the effort must move the lever increases as well. Conversely, if the distance between the fulcrum and the load is decreased, the distance that the lever must move also decreases.

so we have too apply more force to pull the lever cause the distance is 1x smaller then mia lever so on mia lever we ull moree to get it to move!

How do I graph -4x+6y=12
eimsori [14]

You have 2 options.

I will show you the most efficient one, but later I will tell you the other.

-4x+6y=12

6y=4x+12

y=4/6x+12

y=2/3x+12

This tells us the point (0,12) as 12 is where it meets the y-axis (that is why you add it)

And then using the slope, 2/3 we can get (2,15) (which is up 3, right 2)

Just graph those, I would show you exactly, but I cannot add attachments sadly.

The other way (which I won’t show it all as the results would end out with the same line) is to fill in x, then y, with 0

So -4*0+6y=12 which means x=0 and you are solving for y  and -4x+6*0=12 which means y=0 and you are solving for x

Find the value of x.
suter [353]

Answer:

104 degrees

Step-by-step explanation:

71 degrees is one corner

Opposite corner is equal

Middle angle: 180-71-71 = 38

isosceles triangle bottom angle = 38 and 38

top angle = 180 - 38 - 38 = 104 degrees
