The answer is 18.3 because if you all add the sides it will give you 18.3

Perimeter = 18.9

If you observe the triangle, you can see that all of its sides are equal. They are all s, or 6.3 mm. This means that to find the perimeter of the triangle, you can do either of two things:

1. You can multiple s by 3.

2. You can add s three times.

Either way, you will get the same answer. 6.3 • 3 = 18.9, and 6.3 + 6.3 + 6.3 = 18.9

If I am understanding the question correctly, then "type" means the type of triangle this triangle is. To figure this out, look at the measurements of the triangle. All of its sides are equal in length. That means that it is an equilateral triangle.

I know some schools like students to write "equilateral acute" triangles, since all of the angles are less than 90˚. If you want to be sure, I'd contact your teacher and ask.

Hope this helps!

estimate 0.00792398 to the nearest thousandth. Express your answer as a single-digit times a power of ten
Marianna [84]

Answer: \approx8*10^{-3}

Step-by-step explanation:

In order to round to the nearest thousandth, you must observe the digit to the right of the digit in the thousandth place and then:

  • If it is less than 5, you must round down.
  • If it is greater than or equal than 5, you must round up.

In this case, given the number:

0.00792398

You can notice that the digit to the right of the digit in the thousandth place is 9.

Since 9>5, you must round up. Then:

0.00792398\approx0.008

Finally, to express this as a single-digit times a power of ten, move the decimal point three places to the right. Then you get:

\approx8*10^{-3}

Does (2,0) work as a solution to the systems of equations to lines 3x+y=6 and 3x-y=6
fenix001 [56]

Answer:

Yes

Step-by-step explanation:

To see if (2,0) works as a solution to the systems of equations, we plug in the values of x and y and simplify. If the results are equal, then (2,0) is a solution.

3x + y = 6:

  • 3(2) + 0 = 6
  • 6 + 0 = 6
  • 6 = 6
  • (2,0) is a solution to this equation.

3x - y = 6:

  • 3(2) - 0 = 6
  • 6 - 0 = 6
  • 6 = 6
  • (2,0) is a solution to this equation.

Therefore, the answer is yes, it does work as a solution.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
