Answer:

10 sides (decagon)

Step-by-step explanation:

You find the perimeter by adding up all the sides of a shape.

side + side + side + side... = perimeter

You know that each side is 4/5 centimeters. You also know that the perimeter is 8 centimeters.

You can set up an equation like this:

4/5 * number of sides = 8

or you can write it in a simpler form as:

4/5x=8

Now solve it like a normal equation:

5 * (4/5x) = (8) * 5

(4x) / 4=(40) / 4

x = 10

So, you know the shape has 10 sides that are 4/5 centimeters each.

Harlamova29_29 [7]

Ok 15% is 0.15 in decimal form so you multiply 0.15 by 16000$ and get 2,400$ (the down payment not amount owed) you then subtract 2,400$ from 16,000$ and get 13,600$ which is how much he still owes

Answer: x-9

Step-by-step explanation: because x is lower than Tony's money you would have to subtract x (Michelle's money) from Tony's ( which is 9)

This is why the answer would be X-9

A family will travel 350 miles from their house in order to reach Dallas TX. Which inequality can be used to find all possible v

Brrunno [24]

V = d / t => t = d / V

V ≥ r ; d = 350 => t = d / V ≤ 350 / r

Then, t ≤ 350 / r, which is option C.

What is the area of this triangle? A=bh2

Dmitry_Shevchenko [17]

The area of a triangle formal is base times height divided by 2. So 9x 12 which equals 108 then you divide that by 2 which equals 54 and the unit is cm^2

The path traveled by a bottlenose dolphin as it jumps out of water is modeled by the equation y = −0.4x2 + 3x, where y is the he

Dima020 [189]

We can find the answer by solving the two equations simultaneously.

equation 1: y = -0.4x^2 +3xequation 2: x + y = 10
We need to write equation to with y as the subject:equation 2: y = 10 - x

equation 1 = equation 2:
10 - x = -0.4x^2 + 3x0.4x^2 - 4x + 10 = 02x^2 - 20 + 50 = 0(2x - 10)(x - 5) = 0x = -10/2 or x = 5

But x >= 0 (the question says it's a height above the water), so x = 5

Substituting x = 5 into one of the equations:
y = 10 - x
y = 10 - 5
y = 5

So the answer is C
