Answer:

20.56 in

Step-by-step explanation:

The perimeter is the length of the outside of the figure.

This consists of 2 semicircles and 2 straight parts of 4 in

The 2 semicircles can be thought of as 1 circle with circumference

C = 2πr ( r is the radius )

Here diameter = 4 so r = 4 ÷ 2 = 2, then

C = 2 × 3.14 × 2 = 4 × 3.14 = 12.56 in

Thus

perimeter = 12.56 + 4 + 4 = 12.56 + 8 = 20.56 in

Se corta una manzana en 12 partes, se comen ocho partes. Qué fracción simplificada a su mínima expresión representa la cantidad
lakkis [162]

Answer:

A. 1/3

Step-by-step explanation:

Dado que:

una manzana se corta en 12 partes y se comen ocho partes.

La fracción de manzanas consumidas = 8/12

= 2/3

La fracción de manzanas que quedan = valor original de la manzana que se corta - la fracción de la manzana que se come

La fracción de manzanas que quedan  =1-  \dfrac{8}{12}

La fracción de manzanas que quedan  =\dfrac{12-8}{12}

La fracción de manzanas que quedan =\dfrac{4}{12}

A la fracción más baja; obtenemos = 1/3
