The interior angle of a regular

Mathematics
1 answer:
Alexxx [7]3 years ago
7 0

Answer:

12

Step-by-step explanation:

The sum of the exterior and interior angles = 180°

let x be the measure of the exterior angle then interior angle is 5x and

5x + x = 180

6x = 180 ( divide both sides by 6 )

x = 30

The sum of the exterior angles of a polygon = 360°, thus

number of sides = \frac{360}{30} = 12

Yes, she is correct
1/2 + 1/2 = 1 or 0.5 + 0.5 = 1 so half of a wall plus half of a wall equals one hole wall.

That's as simple as I can put it mathematical reasoning. I hope this helps

rectangular prism is lwh

Put in the values you know

15 * 5 * 7 = 525

For a prism you use

\frac{lwh}{3}

Put in the values you know

\frac{15 * 5 *13 }{3}

Multiply

975/3

Divide

325

Add the values you know

325 + 525 = 850

PLEASE HELPPPPP!!!! (answer in decimal)

Answer:

\approx 0.482659

Step-by-step explanation:

The experimental probability is the chance of an event happening based on data, or rather the experiment results, and not on a theoretical calculation. In essence, a theoretical calculation can be described by the following formula:

\frac{desired}{total}

However, the experimental probability can be described with the following formula:

\frac{number\ of\ desired\ outcomes}{number\ of \ trials}

The number of trials is the sum of the number of outcomes. In this case, the desired outcome is tails. Therefore, the experimental probability can be described using the following formula:

\frac{tails}{total}

One can also rewrite the formula as the following. This is because the total is the sum of the number of the two outcomes:

\frac{tails}{heads+tails}

Substitute,

\frac{167}{167+179}

Simplify,

\frac{167}{346}

Rewrite as a decimal:

\approx 0.482659
