joja [24]3 years ago
4 0

Answer:

The answer would be the very last explanation.

Step-by-step explanation:

Considering x=63 it shows that x = 18 + 45 which it is, and it also represents the equation by stating how he spent 18 dollars while shopping and he has 45 dollars left. So meaning he had more in the start unlike the other situations.

What is the volume of the cone? Cone V = 1/3 Bh V = 1/3 πr2h V = 1/3 π32(8) V = 1 3 π(9)(8) V = 1/3 π(72) The cone has a volume
Amanda [17]

The volume of cone is 24\pi or 75.398 cubic centimeters, if the cone has a radius of 3 centimeters and height of 8 centimeters.

Step-by-step explanation:

The given is,

                  Formula for volume of cone, V = \frac{1}{3} Bh

                  Where, B = \pi r^{2}

                  Volume, V= \frac{1}{3} \pi r ^{2} h

                  From the given,

                           Radius, r = 3 centimeters

                          Height, h = 8 centimeters

                 volume, V= \frac{1}{3} \pi (3 ^{2})( 8)

                                    = \frac{1}{3} \pi (9)( 8)

                                    = \frac{1}{3} \pi (72)

                                    = 24\pi

    Volume of cone, V= 24\pi (volume in terms of \pi )

                                ( or )

                    Volume, V = (24 × 3.14 )                        ( ∵ \pi=3.14 )

                                  V = 75.398 cubic inches

Result:

         The volume of cone is 24\pi or 75.398 cubic centimeters, if the cone has a radius of 3 centimeters and height of 8 centimeters.

Solve. 20/n+10 = 10/n+20 n = -10 n = -20 n = 30 n = -30
kirill115 [55]

Answer:

20/n+10 = 10/n+20 n

multiply both side n,

n (20/n+10) = n(10/n+20 n)

20+10n = 10+20n^2

20+10n -20 = 10+20n^2 -20

10n  = 20n^2 -10

10n  - 10n  = 20n^2 -10 -10n

0 = = 20n^2 -10 -10n

20n^2 -10 -10n = 0

n = 1 or n = -0.5

Step-by-step explanation:
