Find the volume of a right circular cone that has a height of 13.1 in and a base with a diameter of 5.7 in

Answers

Answer:

Step-by-step explanation:

1) Divide the diameter in half to make the radius, which equals 2.85 as r.

2) Plug in the radius(r) and height(h) with the correct numbers.

3) Simply solve

V = π(2.85)² × 13.1 ÷ 3

V= 25.52 × 13.1 ÷ 3

V= 334.312 ÷ 3

V= 111.4373+

V≈ 111.43 1) Divide the diameter in half to make the radius, which equals 2.85 as r.

99.95 + 19.99x < 125.79 + 15.99x

99.95 + 19.99x < 125.79 + 15.99x

99.95 + 19.99x > 125.79 + 15.99x

Answers

Answer:

Step-by-step explanation:

because < means bigger and 125 is bigger than 99

Answer:

99.95 + 19.99x ≤ 125.79 + 15.99y    

Step-by-step explanation:

Given:

Luke bought a video game system that costs $99.95 and games that cost $19.99 each.

Bella bought a game system that costs $125.79 and games that cost $15.99 each.

Luke spent no more than what Bella spent.

To Find:

Which inequality represents this situation?

Solve:

Let Luke bought = x.

Let Bella bought = y.

How much Luke paid = $99.95 + $19.99 × x = $99.95 + $19.99x

How much Bella paid = $125.79 + $15.99 × y = $125.79 + $15.99y

Luke paid is equal or lesser than how much Bella paid, then

99.95 + 19.99x ≤ 125.79 + 15.99y

Question 4:

   2x + 3y = 17    -- equation 1

   5x + 6y = 32  -- equation 2

    (equation 1) * 2

    4x + 6y = 34 -- equation 3

    (equation 2) - (equation 3)

     x = -2 -- equation 4

     plug (equation 4)'s value of x into (equation 1)

     2(-2) + 3y = 17

     3y - 4 = 17

      3y = 21

         y = 7

      Thus the answer is x = -2 and y = 7

Question 5:

  The vertex form of a quadrilateral looks like this:

      [tex]y = a(x-h)^2 + k[/tex]

a : coefficient of [tex]x^2\\[/tex](h,k): coordinate of the vertex.

    The x-coordinate of the vertex is equal to '-b/2a'. Where b is the

     coefficient of x, so:

          [tex]h = -\frac{b}{2a} =-\frac{-8}{2*1} =4[/tex]

     

    There is also another formula to find the y-value of the vertex

    coordinate, but the easier way to find it is to plug it into the original

    equation:

        [tex]k=(4)^2-8(4) + 12= 16 -32 + 12 = -16 + 12 = -4[/tex]

    Since we know now that h = 4 and k = -4 and that a = 1, lets plug it into

    the original equation.

       [tex]y = 1*(x-4)^2 - 4 =(x^2-4)-4[/tex]

     Thus the answer is [tex]y = (x-4)^2 -4[/tex]

Hope that helps!
