8x + (2x - 14)= 7x + 3x -14

10x -14= 10x - 14

These equations are identical, so it would be the  identity property and the answer would either be identity or the fancy 'R'.

The volume of a cone is 18π cubic feet. If the height of the cone is 6 ft, what is the radius of the cone? (V = 1 3 πr2h)
svetoff [14.1K]

Answer:

Volume = 1/3πr^2h

18π = 1/3πr^2 x 6

18 = 2r^2

9 = r^2

r = 3 ft.

Hope this helps you!

Sv is an angle bisector of rst. If mrsv = (3x+5) and mrst = (8x-14), find x.
MA_775_DIABLO [31]

m∠RSV = 3x + 5, m∠RST = 8x - 14       <em>given</em>

m∠RSV ≅ m∠VST                                 <em>definition of segment bisector</em>

m∠RSV + m∠VST = m∠RST                 <em>angle addition postulate</em>

(3x + 5) + (3x + 5) = (8x - 14)                  <em>substitution</em>    

6x + 10 = 8x - 14                                    <em>simplify (added like terms)</em>

       10 = 2x - 14                                    <em>subtraction property of equality</em>

      24 = 2x                                           <em>addition property of equality</em>

      12 = x                                              <em>division property of equality</em>

Answer: x = 12

Select all the pairs that could be reasonable approximations for the diameter and circumference of a cirlce 5 meters and 22 mete
bazaltina [42]

Answer:

Option a) circle 5 meters and 22 meters

Step-by-step explanation:

We are given the following information in the question:

A pair of diameter and the circumference is given. We have to find a correct approximations for the diameter and circumference.

a) circle 5 meters and 22 meters

\text{Diameter} = 5\text{ meters}\\\text{Circumference} = \pi d = 3.14\times 5 = 15.7\text{ meters}

b) 19 inches and 50 inches

\text{Diameter} = 19\text{ inches}\\\text{Circumference} = \pi d = 3.14\times 19 = 59.66\text{ inches}

c) 33 centimeters and 80 centimeters

\text{Diameter} = 33\text{ centimeters}\\\text{Circumference} = \pi d = 3.14\times 33 =103.62\text{ centimeters}

Thus, no pair gives a reasonable approximation. Only the circle with diameter 5 and circumference 22 meters have closest approximation.

A = 1 + w : Solve for w
myrzilka [38]

Answer:

A - 1 = w

Step-by-step explanation:

Step 1: Write equation

A = 1 + w

Step 2: Subtract 1 on both sides

A - 1 = 1 + w - 1

A - 1 = w
