2^5 over 4 = 2^5 over 2a = 2^b = c What are a b and c
likoan [24]

Answer:

a = 2

b = 3

c = 8

Step-by-step explanation:

<em>2^5/4</em>=<em>2^5/2a</em>=<em>2^b</em>=<em>c</em>

      <em>2^5/4</em>, 2^5 = 32, 32/4 = 8

             so c, being what all of this is equal to, is 8

      <em>2^5/2a</em>, 2*2=4

              so a = 2

      <em>2^b </em>= 8, ∛8 =  3

              so b = 3

Hope my explanation makes sense :)

You design the wooden picture frame and paint the front surface.
Hitman42 [59]

Answer:

  • a) 8x + 28
  • b) 68 in²

Step-by-step explanation:

a)

<u>Area of the frame with picture:</u>

  • A = lw
  • A₁ = (x + 4)(x + 7) = x² + 11x + 28

<u>Area of the picture:</u>

  • A₂ = x(x + 3) = x² + 3x

<u>Area of the wooden frame is the difference of the above values:</u>

  • A₃ = A₁ - A₂
  • A₃ = x² + 11x + 28 - x² - 3x
  •     = 8x + 28

b)

<u>When x = 5, the picture frame area is:</u>

  • A₃ = 8*5 + 28 = 40 + 28 = 68 in²

What is the volume of a cylinder, in cubic centimeters, with a height of 7 centimeters
devlian [24]

Answer:

The volume of a cylinder is 1782\ cm^3.

Step-by-step explanation:

We have,

Height of cylinder, h = 7 cm

Diameter of cylinder, d = 18 cm

Radius, r = 9 cm

It is required to find volume of cylinder. The formula of the volume of cylinder is given by :

V=\pi r^2h\\\\V=\dfrac{22}{7}\times (9)^2\times 7\\\\V=1782\ cm^3

So, the volume of a cylinder is 1782\ cm^3.
