<u>Answer:</u>

The correct answer option is B. 72°.

<u>Step-by-step explanation:</u>

A polygon is said to be a regular polygon when all its sides and angles are equal.

So a regular pentagon coincides with its pre-image when it is rotated at an angle of 72°.

When rotated at an angle of 72°, a regular pentagon produces the same pentagon regardless of being rotated clockwise or anticlockwise.

Therefore, option B is the right choice.

La suma de dos número impares consecutivos es 100 . hallar la suma de cifras del mayor<br> numero
gtnhenbr [62]
<h2><u>solución</u></h2>

deja que los números sean x, and x + 2

sabemos que su suma es igual a 100, entonces

  • x + x + 2 = 100

  • 2x = 100 - 2

  • 2x = 98

  • x = 98 ÷ 2

  • x = 49

por lo tanto, el primer número es 49

y el segundo número es x + 2 = 49 + 2 = 51 (también es el mayor entre los dos números)

entonces suma de dígitos de mayor número = 5 + 1 = 6

Respuesta correcta de la pregunta anterior = 6

Julius is buying beverages for brunch. He needs to buy a total of 5
xeze [42]
Well, he only needs 5 gallons of beverages. Because he buys two containers of each, however, that means he bought 320 gallons total (I would say). How I got my answer:

There are 8 pints in a gallon (8 x 2)
There are 4 quarts in a gallon (4 x 2)
There are 16 cups in a gallon (16 x 2)
There are 128 ounces in a gallon (128 x 2)

With that being said, we can add these to find the total amount of gallons of beverages Julius bought. 16 + 8 + 8 + 32 + 256 = 320.

Hopefully this helps!
