A= 1/2 x a x b x sinC
= 1/2 x 77 x 76 x sin(47)
= 2139.9409

One number is six times as large as another. The sum of their reciprocal is 7. What are the numbers
RideAnS [48]
X=6y

sum of their reciprocals
(1/x)+(1/y)=7
x=6y
1/6y+1/y=7
1/6y+6/6y=7
7/6y=7
times both sides by 6y
7=42y
divide both sides by 42
1/6=y

x=6y
x=6(1/6)
x=6/6
x=1

the numbers are 1 and 1/6

-9 a que conjunto pertenece -4/4 a que conjunto pertenece -5.124 a que conjunto pertenece rapidoo pls
Hunter-Best [27]

Answer:

-9 al conjunto de los números enteros.

-4/4 pertenece a los enteros.

-5.124 pertenece al conjunto de los racionales

Step-by-step explanation:

En esta pregunta, básicamente lo que debes hacer es clasificar cada uno de los números de acuerdo al conjunto numérico. Como podrás ver en la foto 1, tienes una representación gráfica de los conjuntos numéricos existentes.

Los números naturales (N), comprenden desde el 1 hasta el infinito.

Los números enteros (Z) comprenden los negativos, el cero y todos los naturales.

Finalmente los números racionales (Q) comprenden los números enteros, los naturales y también fracciones y números decimales.

De acuerdo a estas definiciones y la foto, podemos observar que todos los números dados acá pertenecen al conjunto general de los racionales (Q), pero veamos ahora específicamente a cual:

El número -9 (o el 9) si es negativo, pertenece a los enteros; si es positivo sería entero y natural.

El número -4/4 es una fracción, que al ser dividida da como resultado el número -1, y este pertenece a los enteros.

El número -5.124 (o 5.124) es un número decimal finito, por lo que proviene de una fracción, asi que pertenece a los números racionales.

Espero que esto te ayude.

Graph Ex+ 3y = 24<br> a.<br> b.<br> c.<br> d.
8090 [49]

Answer:

(b)

Step-by-step explanation:

Given

8x + 3y = 24

Required

The graph

First, make y the subject

3y = 24 - 8x

Divide through by 3

y = 8 - \frac{8}{3}x

Let x = 3

y = 8 - \frac{8}{3}*3 = 8 - 8 = 0

Let x = 6

y = 8 - \frac{8}{3}*6 = 8 - 16 = -8

So, we plot the graph through

(3,0) and (6,-8)

See attachment for graph
