Answer:

7/8 . 6/7

9/10 . 5/6

Step-by-step explanation:

B and C or you could say 2 and 3 are the right ones

pentagon [3]2 years ago

1/2x1/2 = 0.25
7/8 x 6/7 = 0.75
9/10 x5/6 = 0.75
3/4x 3/4 = 0.5625
1/4 x 1/2 = 0.125
So its B and C because 0.75 as a fraction is 3/4!

Answer:

<em>y = - x + 6 </em>

Step-by-step explanation:

<em>--</em><em> </em>Rhombus diagonals <u><em>are perpendicular and bisect</em></u> each other.

<em>--</em><em> </em>A( x_{1} , y_{1} ) and B( x_{2} , y_{2} )

Coordinates of <u><em>the midpoint</em></u> of a segment AB are

( \frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )

and <u><em>formula of a slope</em></u> of the line segment AB is

m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

<em>-- </em>If AB ⊥ CD then m_{AB} × m_{CD} = - 1

<em>-- </em><u><em>Slope-point of linear equation</em></u> is

y - y_{1} = m( x - x_{1} )

~~~~~~~~~~~~~~~~

M(0, 2)

T(4, 6)

m_{MT} = \frac{6-2}{4-0} = 1

m_{AH} = - 1

Coordinates of the intersection of the diagonals are ( \frac{4+0}{2} , \frac{6+2}{2} ) = (2, 4)

y - 4 = - 1(x - 2)

<em>y = - x + 6</em> <u><em>is slope-intercept form of the diagonal AH</em></u>

The cone and cylinder above have the same radius and height. The volume of the cone is 210 cubic centimeters. What is the
Juli2301 [7.4K]

Answer:

706.3 cm³

Step-by-step explanation:

<u>Given</u>

<em>"The cone and cylinder above have the same radius and height..."</em>

<em>the volume of the cone = 210 cubic centimeters</em>

<u>Formula</u>

The formula for the volume of a cylinder is V=Bh or V=πr2h. The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h.

<u>How to solve</u>

Given radius and height calculate the volume, lateral surface area, and total surface area.

Calculate V, L, A | Given r, h

use the formulas above

Given radius and volume calculate the height, lateral surface area, and total surface area.

Calculate h, L, A | Given r, V

h = V / πr2

Given radius and lateral surface area calculate the height, volume, and total surface area.

Calculate h, V, A | Given r, L

h = L/2πr

Given the height and lateral surface area calculate the radius, volume, and total surface area.

Calculate r, V, A | Given h, L

r = L/2πh

Given height and volume calculate the radius, lateral surface area, and total surface area.

Calculate r, L, A | Given h, V

$r = √( V / πh )
