The equations to represent the relationship are ƒx3/5=4 4/5 and 4 4/5 divided 3/5 =f

<h3>Ratio and proportion</h3>

Fractions are written as a ratio of two integers. For instance a/b is a fraction.

If Anastacio distributed 4 4/5 kg of seed among several bird feeders and put 3/5 kg of seed in each feeder, the expression that represents the number of bird feeders that Anastacio filled is given as;

Number of bird feeder = 4 4/5 ÷ 3/5

f = 4 4/5 ÷ 3/5

Multiply both sides by

f * 3/5 = 4 4/5   ÷ 3/5 * 3/5

f * 3/5 = 4 4/5

Hence the equations to represent the relationship are ƒx3/5=4 4/5 and 4 4/5 divided 3/5 =f

Can y’all help with geo?
VladimirAG [237]

Here's the solution,

<u>figure</u> 1.

by using trigonometry,

=》

\sin(60)  =   \dfrac{5 \sqrt{3} }{y}

=》

\dfrac{ \sqrt{3} }{2}  =  \dfrac{5 \sqrt{3} }{y}

=》

\dfrac{1}{y}  =  \dfrac{ \sqrt{3} }{2 \times 5 \sqrt{3} }

=》

\dfrac{1}{y}  =  \dfrac{1}{10}

=》

y = 10

And,

=》

\cos(60)  =  \dfrac{w}{y}

=》

\dfrac{1}{2}  =  \dfrac{w}{10}

=》

w = 5

So, values are :

  • y = 10
  • w = 5

<u>figure</u> 2.

Since, it's an isosceles triangle, w = y,

So, by pythagoras theorem :

=》

{w}^{2}  +  {y}^{2}  = (7 \sqrt{2} ) {}^{2}

=》

{w}^{2}  +  {w}^{2}  = 98

=》

2 {w}^{2}  = 98

=》

{w}^{2}  = 49

=》

w =  \sqrt{49}

=》

w = 7

and we know, w = y, so their values will be equal to 7 units.
