Joni’s hair is 13 inches long and grows at an average rate of ⅔ in per month. Her friend Kate’s hair is 16 inches long and grows
Gelneren [198K]
<h3>18 months will pass before the two friends have the same hair length</h3>

<em><u>Solution:</u></em>

Let "x" be the number of months

Joni’s hair is 13 inches long and grows at an average rate of ⅔ in per month

Equation : 13 + \frac{2}{3}x ------- eqn\ 1

Her friend Kate’s hair is 16 inches long and grows at an average rate of ½ in per month

Equation: 16 + \frac{1}{2}x ----- eqn\ 2

<em><u>For two friends to have the same hair length, eqn 1 must be equal to eqn 2</u></em>

13 + \frac{2x}{3} = 16 + \frac{x}{2}\\\\\frac{2x}{3} - \frac{x}{2} = 16 - 13\\\\\frac{4x}{6} - \frac{3x}{6} = 3\\\\x = 18

Thus 18 months will pass before the two friends have the same hair length

Audrey takes a sheet of paper and makes a diagonal cut from one corner to the opposite
Elodia [21]

\large{\underline{\underline{\pmb{\frak {\color {blue}{Solution:}}}}}}

Let us take the width of the paper as base, the cut she made be hypotenuse and the paper's length be perpendicular.

Here,

Hypotenuse (H) = 87 inch

Base (B) = 60 inch

Perpendicular (P) = [To be calculated]

As, we can use Pythagoras theorem to find. So by using Pythagoras theorem :

H² = P² + B²

{87}^{2}  =   {P}^{2}  +   {60}^{2}  \\  \\  \implies \: 7569 =   {P}^{2}  + 3600 \\  \\  \implies \: 7569 - 3600 =  {P}^{2}  \\  \\  \implies3969 =  {P}^{2}  \\  \\  \implies \: P =  \sqrt{3969}  \\  \\ \implies \: P = 63

The length of the paper is 63 inches.

\boxed{ \frak \pink{BrainlyDamurai}}
