One leg of a right triangle is 7 inches longer than the other leg, and the hypotenuse is 35 inches. Find the lengths of the legs
lilavasa [31]

Answer: 21, 28

Step-by-step explanation:

  • Side #1 = x
  • Side #2 = x + 7
  • Hypotenuse = 35

Use the Pythagorean Theorem a^{2}+b^{2}=c^{2}:

  • a = x
  • b = x + 7
  • c = 35

Substitute in the values & solve:

x^{2}+(x+7)^{2}=35^{2}\\x^{2}+x^{2}+14x+49=1225\\2x^{2}+14x+49-1225=0\\2x^{2}+14x-1176=0\\2(x^{2}+7x-588)=0\\2(x + 28)(x - 21)=0\\x_{1}=-28, x_{2}=21

<em><u>-28 is not a possible solution since you can't have negative inches...</u></em>

  • a = x = 21
  • b = x + 7 = 21 + 7 = 28
  • c = 35

Felipe trabaja en una construcción ayuda a cotizar materiales entre ellos cables para diversos propósitos el arquitecto le pidió
valina [46]

Answer:

a) 0.64mm

b) 7/25

Step-by-step explanation:

Felipe trabaja en una construcción ayuda a cotizar materiales entre ellos cables para diversos propósitos.El arquitecto le pidió cotizar un cable de 16/25 mm de diámetro. en los catálogos disponibles en as tiendas las medidas aparecen expresadas en números decimales como se muestra en la imagen

¿Que debe hacer felipe para saber el diámetro del cable que pidió el arquitecto?

¿que medida en forma de fracción le corresponde al cable que mide 0.28? ¿como lo determinaste? es urgenteeee GRACIAS

a)Para que obtengamos la medida del material expresada como decimal, usaremos el método de división larga. compruebe el archivo adjunto para la solución a la división.

16/25 mm = 0,64 mm

b) La medida fraccionaria corresponde al cable que mide 0.28 se expresa como se muestra. Convertir 0,28 a fracción.

0.28 = 28/100 (Tenga en cuenta que dividimos por 100 porque hay dos valores decimales después del punto decimal)

Sobre la simplificación en su término más bajo

0.28 = 28/100 = 2*14/2*50

0.28 = 28/100 = 14/50

simplificando aún más

0.28 = 14/50 = 2*7/2*25

0.28 = 14/50 = 7/25

28/100 = 7/25

Por lo tanto, la medida fraccionaria que corresponde al cable que mide 0.28 es 7/25.
