Vanessa wants to determine the perimeter around her garden. She makes an small model of her garden and combines all the sides: 3
son4ous [18]

Answer:

4

Step-by-step explanation:

since it's all addition, we can remove the parentheses

3x + x + 10 + 5x + 2x + 2 = 56

Now we combine like terms

3x+x+5x+2x+10+2=56

11x+12=56

We subtract both sides by 12 to get,

11x=44

now we divide both sides by 11

x=\frac{44}{11}

x=4

A funnel is made up of a partial cone and a cylinder as shown in the figure. The maximum amount of liquid that can be in the fun
zavuch27 [327]
The volume of the partial cone is the volume of the entire funnel minus the volume of the cylindrical part.

The volume of a cylinder is given by:

V=\pi r^2h
where: r is the radius of the cylinder and h is the height of the cylinder.

Given that the cylindrical part of the funnel has a height of 1.5 cm and a diameter of 1.5 cm, thus the radius is 1.5 / 2 = 0.75 cm and the volume is given by:

V=\pi(0.75)^2(1.5)=0.84375\pi=2.65072cm^3

Therefore, the volume of the partial cone is given by 16.59375 - 2.65072 = 13.94303 cubic cm.

Can u help? thank you.​
zysi [14]

Answer:

  y = -1/2x +1/2

Step-by-step explanation:

Point B is 4 up and 2 over from point A. So, the midpoint will be 4/2 = 2 up and 2/2 = 1 over, at (1, 0).

The ratio of rise to run between A and B is ...

  m = rise/run = 4/2 = 2

The perpendicular line will have a slope that is the opposite reciprocal of this, -1/2.

Then the point-slope equation for the perpendicular bisector is ...

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

  y -0 = -1/2(x -1) . . . .line with slope -1/2 through point (1, 0)

  y = -1/2x +1/2 . . . . simplified to slope-intercept form
