Answer:

\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{4}{3}

Step-by-step explanation:

Let the length of rectangle A be x units.

So, length of rectangle B

= x + 25% of x

= x + 0.25x

= 1.25x

Let the width of rectangle A be y units

So, Width of rectangle B

= \frac{3}{5}\times x\\=0.6x

Area of rectangle A = xy

Area of rectangle B

= 1.25x * 0.6y

= 0.75xy

\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{xy}{0.75xy}\\\\\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{1}{0.75}\\\\\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{100}{75}\\\\\red{\bold{\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{4}{3}}} \\\\

Answer:

The circumference is 75.36 inches.

Step-by-step explanation:

Hi there! Please take a look at the following explanation and let me know in the comment if you have any doubts!

<h3>Given:</h3>

We are given the <u>radius</u> that’s equal to <u>12 inches</u> and π = <u>3.14</u>

<h3>Problem:</h3>

We want to find <u>the circumference</u>.

<h3>Circumference Formula:</h3>

\displaystyle \large{C=2\pi r} which simply means <em>circumference = 2*π*radius</em> or sometimes can also be written as \displaystyle \large{C=\pi d} which means <em>circumference = π*diameter </em>since 2r means two times of radius and that’s technically diameter.

<h3>Step:</h3>

Determine the following:

  • π = 3.14 as given
  • r = 12 as given

Apply the circumference formula.

\displaystyle \large{C=2\cdot 3.14 \cdot 12}\\\\\displaystyle \large{C = 24 \cdot 3.14}\\\\\displaystyle \large{C=75.36}

Hence, the circumference is <u>75.36 inches</u>.

[(2/3)^2]^3 X (2/3)^2 ÷ (2/3)^8 ​
skad [1K]

Answer:

Reduce the expression, if possible, by cancelling the common factors.[(2/3)^2]^3 X (2/3)^2 ÷ (2/3)^8 ​ = 1

Step-by-step explanation:

4/9^3 x (2/3)^2 ÷ (2/3)^8

4/9^3 x 4/9 ÷ (2/3)^8

4/9^3 x 4/9 divided by 256/6561

64/729 x 4/9 divided by 256/6561

= 1
