Answer:

The regular decagon has 10 axes of symmetry.

Step-by-step explanation:

A regular decagon is made up of ten sides and ten vertices. Each vertex is located exactly in front of another vertex (opposite). Then, by drawing axes that join two opposite vertices, five axes of symmetry can be constructed.

Each side is located exactly opposite the other side of the decagon (opposite). Then, joining the midpoints of each side, with their respective opposite, five axes of symmetry are constructed for the decagon.

Conclusion: the regular decagon has 10 axes of symmetry.

The number of sides is the same as the number of lines of symmetry and the order of rotational symmetry.

So, a regular decagon would have 10 lines of symmetry.

Write an equality that represents eight less that three times a number is more than 22

leonid [27]

Answer:

3x - 8 > 22

Step-by-step explanation:

" eight less" means to subract 8 form something. If you had 10 apples and I took some so now you had 8 less apples, you'd have 10 - 8 = 2 apples

"three times a number" means 3x. 3 times some number.

The expression 3x - 8 means "8 less than 3 times a number"

"is" is math is a statement of equality, either an equals sign or an inequality needs to go here.

Our inequality is

3x - 8 > 22

PLEASE HELP!!!

44.

The closer it gets to -19, the closer the number goes to 44. It never hits it exactly though, but based off the trend (43.95, 43.995, 43.9995) we can tell that it gets closer to 44 each time.

Hope this helps! (:

Reuben bought a desktop computer and a laptop computer. Before finance charges, the laptop cost $150 more than the desktop. He p

Same case as Pablo's, more or less.

a = price for the desktop

b = price for the laptop

we know the laptop is 150 bucks more than the desktop, b = a + 150.

how much is 7% of a? (7/100) * a, 0.07a.

how much is 9.5% of b? (9.5/100) * b, 0.095b.

total interests for the financing add up to 303, 0.07a + 0.095b = 303.

$\bf \begin{cases}
\boxed{b}=a+150\\
0.07a+0.095b=303\\
----------\\
0.07a+0.095\left(\boxed{a+150} \right)=303
\end{cases}
\\\\\\
0.07a+0.095a+14.25=303\implies 0.165a=288.75
\\\\\\
a=\cfrac{288.75}{0.165}\implies a=1750$

how much was it for the laptop? well b = a + 150.
