La mamá del profesor Ernesto tiene una bolsa con 3/4 kilogramos de arroz y guiso 2/3 de su contenido Que fracción de un kilogram
VARVARA [1.3K]

Answer: ella usó (1/2) kg de arroz para cocinar.

Step-by-step explanation:

La madre de Ernesto tenía una bolsa con 3/4 kg de arroz.

Sabemos que uso 2/3 de esa cantidad para hacer un guiso.

Entonces ella usó 2/3 de 3/4 kilogramos de arroz.

Entonces ella usó:

(2/3)*(3/4) kg de arroz.

Recordemos que esto se puede escribir como el producto entre los numeradores dividido por el producto de los denominadores:

(2*3)/(3*4) kg de arroz.

(6/12) kg de arroz

(1/2) kg de arroz.

Esto significa que ella usó (1/2) kg de arroz para cocinar.

Does 24, 7, and 26 form a right triangle
const2013 [10]

Answer:

No. It is an obtuse triangle.

Step-by-step explanation:

If c^2>a^2+b^2, then the triangle is obtuse. Since 24^2 + 7^2 is 625, and the square root of 625 is 25, that means 26>25. This proves that the triangle is obtuse.
