A regular octagon with side length a cm can be made by cutting off
Ksivusya [100]

Answer:

one side = \frac{a\sqrt{2}}{2}

Step-by-step explanation:

if you draw an octagon on a piece of paper, you can draw a square around it, you should be able to see a diagram of this attached, ignore the 6.

Let's say TP = a

since it's a regular octagon, TP = HT

and using the Pythagoras Theorem,  we know a² + b² = c² and thus:

√(AT² + HA²) = HT

and since AT = HA which we will call x, the equation becomes:

√(2x²) = HT = a

rearrange the equation to solve for x and you get:

2x² = a²

x² = \frac{a^{2} }{2}

x = \frac{a}{\sqrt{2}}

which, if you rationalise the denominator, you get:

x = \frac{a\sqrt{2}}{2}

I NEED NUMBER 24 ONLY PLEASEEEEEEEEEEEE I NEED HELP I DON’T GET IT!!!!!!
siniylev [52]

Answer:

$325,120.00

Step-by-step explanation:

This is my first answer so hopefully I do this correctly. In essence it's exactly the same as number 22!

The realtor earns $10,566.40 off of a comission of 3.25%. A comission is pretty much just a cut of however much the house cost; which a realtor gets for helping to sell the property. So we could say that the comission is equal to 3.25% of however much the house cost.

Say the house price = $x, so our equation would be:

$10,566.40 = (3.25%)•($x) or

10,566.40 = (.0325)•($x)

By solving for x we get:

$x = (10,566.40)÷(.0325) = $325,120
