Answer:  The correct expression is (A) \dfrac{4}{3}\pi(7)^3.

Step-by-step explanation:  We are given to select the correct expression that gives the volume of a sphere with radius 7 units.

We know that

the VOLUME of a sphere with radius 'r' units is given by

V=\dfrac{4}{3}\pi r^3.

Here, the radius of the given sphere is

r = 7 units.

Therefore, the volume of the sphere will be

V=\dfrac{4}{3}\pi r^3\\\\\\\Rightarrow V=\dfrac{4}{3}\pi (7)^3.

Thus, the required expression is \dfrac{4}{3}\pi(7)^3.

Option (A) is correct.

Una bolsa contiene 4 canicas azules, 4 canicas rojas y 4 canicas verdes. Sacas aleatoriamente una canica y luego otra (sin reemp
sveticcg [70]

Answer:

la probabilidad es 1/11

Step-by-step explanation:

Hay 4+4+4 = 12 canicas en total en la bolsa.

Pues la posibilidad de sacar una canica azul en el principio es 4/12 o 1/3.

Y luego, no reemplaces la canica, y hay 11 canicas en total.

Por eso la posibilidad de sacar otra canica azul después es 3/11.

Son eventos independientes, y tenemos que multiplicarlos para tener la respuesta.

1/3 * 3/11 = 1/11

(−7c+8d)0.6 distributive property
Ksivusya [100]

We are given

(-7c+8d)0.6

we can use distribute property

Distributive property:

(A+B)C=A*C+B*C

so, we can write it as

(-7c+8d)0.6=-7c*0.6+8d*0.6

(-7c+8d)0.6=-7*0.6c+8*0.6d

now, we can multiply terms

and we get

(-7c+8d)0.6=-4.2c+4.8d..............Answer
